The (not so) secret ingredient to making your mixes sound good

When you start creating mixes, you quickly realize that the low and low-mid frequencies are problematic. Without care and attention, they can sound muddy, boomy, and unclear. Mid- and high frequencies are much easier to manage—you can have multiple instruments and voices taking up the same sonic bandwidth and still hear everything clearly. Try this in the low frequencies and it’s a mess.

We feel low frequencies in our bodies. It’s where the punch, the groove, and the drive of a track lives. It’s critical to your mix that instruments in the low frequencies be clear, full, and bold.

As with many mixing decisions, it’s not about increasing the level or power of bass elements; rather, it’s about eliminating the stuff that gets in their way.

The Secret

Enter the ubiquitous high-pass filter. The name is fairly self-explanatory; it filters out sound so that only high-frequencies pass through. The high-pass filter is sometimes called a low-cut filter. It’s easy to see how it works with a diagram. The horizontal represents frequencies, and the vertical represents amplitude, or volume.

In this example, the filter is set at 80 Hz, which means everything under 80Hz will be reduced in volume—just follow the slope of the line. For reference, 80 Hz is about the same as the low E string on a guitar. The low E string on a bass is one octave lower, about 40 Hz (that’s E2 and E1 on the piano).

For most instruments, including the human voice, there’s very little of value below 80 Hz. The bass guitar and thud of the kick drum usually live between 40 Hz and 250 Hz. So, the general wisdom is to high-pass everything except the bass and kick drum to 80 Hz or higher. The kick and bass will then have room to be heard clearly, which usually adds punch and groove to your mix.

Every single digital audio workstation (DAW, the software you use to record audio) has a high-pass filter. Usually, it’s a feature of your EQ (equalization) plug-in.

How high is your high pass?

The next question, then, is how high should you set your high-pass filters? That depends on your material. The rule of thumb is to dial up the filter during playback on a track until it starts sounding thin, then back down a bit. If you high-pass too much on guitars, pianos and vocals, you could rob the mix of warmth and body. If something sounds thin in solo, it could be just right in the mix; never judge your settings when listening to a track in solo—it only matters if the mix sounds good.

High-pass filters can also be used on bass and kick drum, but normally they are set very low. For dance music, you may want to include and emphasize the sub-bass (below 40 Hz). For most rock, pop, country and folk tracks, I recommend minimal high-pass filters on the bass and kick drum. Again, what matters is the kind of sound you’re after. Mix with purpose and you’ll get what to where you want to be much faster.

Microphones with high-pass filters

Some microphones have a switch for a high-pass filter. Usually it looks like this, where the crooked line indicates the “on” position for the filter. Usually they’re fixed at 80 Hz.

If you’re recording vocals or guitar (where there will be a bass in the arrangement), it’s advisable to use the high-pass filter on your microphone. Eliminating low frequencies you know you’re not going to need during the recording phase allows you to record a more consistent, louder signal.

Always mix with purpose

Finally, it’s easy to get carried away and high-pass everything judiciously. If you mix with purpose and subtlety, the overall effect can be dramatic. In other words, a subtle high-pass filter on 8 tracks, when they are all mixed together, can make a big difference.

I’ve personally found using high-pass filters to be the one technique that is universally effective on just about any mix, from a simple voice-over narration to a full band. Next to volume, it’s the move that makes the biggest difference to your mixes—in a good way.

If you’ve never mixed with using a high-pass filter, try it out on an old mix and see if it doesn’t clear out the muddiness and open up the sound. I’d love to hear your thoughts—leave a comment below.

Light Your Way collaborative songwriting

As part of the indie rock band Beige Shelter, we were approached to write a new song for a youth gang prevention event. Although we declined to perform for the event, we realized our new song was also a great message for mental health awareness and conversation.

My friend and Beige Shelter frontman Adi Aman had written a song a few years ago with a message to help out a friend going through some tough times. Adi sent me a rough recording and his lyric/chord sheet to play around with. In particular, he said he wasn’t very happy with the melody. Before I even got a chance to look at it, he followed up with a revised lyric that was more poetic and a bit more abstract.

The rewriting process

At the time, we were still involved in the youth prevention event, and I took this angle when rewriting the song. I thought a more direct lyric would be more effective in reaching young people. I also wanted to highlight the aspect of reaching out for help and getting it from friends and family. This, to me, is at the cornerstone of good mental health—people need to be willing to come forward and talk to someone they trust, and their communities need to be willing to listen, empathize and help as best they can.

I printed out Adi’s lyrics and chords and sat at my piano to work on the song. Starting with small edits, I quickly found myself rewriting entire phrases. I realized that using Adi’s lyrics as springboards, I could develop a much more direct song, and marry a melody to the words more easily. This is the sort of lyric I never would have come up with on my own, but using Adi’s original take as inspiration gave me the direction and focus I needed. Here are the working pages I used:

Page 1
Page 2
Page 3

I took care to develop a simple, flowing chord progression and catchy melodies. It was amazing how much mileage I could get from using C, G, F, and Am by playing around with the time between each chord change. I introduced a new, unheard chord to start the pre-chorus section. In other words, the Dm had not been heard in the song yet, but the rest of the pre-chorus chords were also used in the verse. This, along with the melodic centre change, was enough to give the listener a sign-post that the pre-chorus was a new section. For the chorus, I returned to the base C major chord but lifted the melody again.

Back and forth

I presented the revised song to Adi and he liked it very much. He had a few revisions for some of the chord changes, especially the unusual chords I used to end the chorus. Adi felt keeping it simple would be more effective, and once he sung it with his rich voice, I was compelled to agree.

Our bass player Tom made a suggestion for a lyric change at the end of the second verse:

Me: It goes “For your grief, but you know…” which is kinda cheap. We need a good word that rhymes with “grief.”

Tom: Believe.

Adi (singing): For your grief, but believe…

Me: And that flows great into the pre-chorus lyric “You have got the strength to carry on…” — well done, Tom!

Feedback from other songwriters

I presented the song at a Songwriter’s Cafe Meetup by playing back the recording from our latest rehearsal. Members found the song to have an inspiring message without being didactic, and with a good flow to the chords and melody.

We adopted two points from the group to improve the song:

  1. Revised the chorus lyric “And you think that there’s no way to see the light” to “And you think there’s no way out of your plight” so that the word “light” isn’t featured twice in the chorus.
  2. Extended the ending to repeat the main hook “We’ll be lighting your way” a few times before finishing the song.

Recording and Producing

We wanted to release Light Your Way as a single during the CMHA (Canadian Mental Health Association) Mental Health Week between May 1 and May 7. I knew this would be a tight schedule to get it arranged, recorded, mixed, and released.

During our first recording session, we were still finessing lyrics and making small changes to the chords. I used a rehearsal recording to set the tempo for a drum loop. I recorded Adi playing his acoustic guitar and then recorded his vocals.

Tom recorded a bassline at his home studio and sent it to me. Meanwhile, I developed a drum track and added some piano comping. Our lead guitarist, Karan, was busy with final exams and couldn’t commit to the recording session. I asked singer-songwriter and guitarist Paul Vos to contribute lead guitar based on some noodling I had done on my keyboard. Paul did an awesome job with the last minute crunch and played the part with great finesse.

During the mixing stage, I decided the piano track wasn’t helping and re-recorded an electric piano track with a little more interest than simple comping. I still wanted the acoustic guitar to be the main rhythm instrument—the electric piano was just there to add some weight to the track. I also added a string pad and a tambourine to thicken up the choruses. Finally, I recorded some vocal doubles with Adi for the choruses, again, to give them a little more thickness.

Final release

We wanted something unique for the cover art. Adi happened to see a canvas watercolour painting of tulips that my wife Hema had done a few years ago. He liked it enough to ask her if we could use it for the cover art. She gave us her blessing, and I took a photo of it to develop the cover. We kept it very simple, with the Beige Shelter logo and the title. A big thanks to Hema for her beautiful contribution!

Here’s the final track, which is available on Spotify, iTunes, Apple Music, Google Music and other digital retailers. It was a great joy and privilege to write and produce this song with Adi, Tom, and Paul. Enjoy!

7 ways to bring variety to your collection of songs

When writing a collection of songs, whether for a album release or in general, we sometimes end up playing it safe and resorting to tried and true motifs and ideas for every song.

For myself, when I become a fan of an artist or band, I like to hear a variety of songs. Sometimes the differences are obvious, like a ballad vs. a rockin’ out song. And sometimes, the variety comes in more subtle ways—-ways that only looking closer reveals. Your audience will know something feels different and unique, but only the more discerning listeners will know the how and the why.

More than likely, you’re already doing some of these “7 ways” — they are by no means truly unique ideas, as my examples of popular songs will show. Some of them may not work for you, and this list is by no means exhaustive. Hopefully, looking at these will spur on some more ideas. So let’s get into it.

One: Play with the structure

The typical verse, chorus, verse, chorus, bridge, chorus structure is a go-to for many songwriters. But you don’t have to look any further than the Beatles for excellent examples of structural inventiveness. In I Feel Fine, for example, the title occurs at the end of each verse. Then there’s a “B” section that almost sounds like a bridge, until it repeats later, and then maybe you can call it the chorus. Who knows? And more importantly, who cares? It’s all catchy, the title is clear, and the changes are frequent, regular, and interesting. They did something similar with A Hard Day’s Night, and we argued about discussed it on an episode of Song Talk Radio.

When you play around with structure, the parts of the songs sometimes defy conventional nomenclature. Call it a bridge or a chorus, it doesn’t matter; it’s merely semantics. Sometimes it’s more effective to use terms like “A section”, “B section”, and “tag.”

Sometimes the narrative you establish can inspire an unconventional structure. For my song, Depend on Me, I established a narrative with three distinct parts: an easy going afternoon drive, a car accident, and the aftermath. This structure inspired me to begin the song with a simple verse chorus, verse chorus, then a bridge (for the accident) and a completely new section for the aftermath.

Two: Write a song with very few or no perfect rhymes.

Rhymes are usually an integral part of any song in a popular medium. If there’s anything most genres have in common, it’s rhyming. More “pop” songs characteristically have lots of perfect rhymes. At the other end, folk songs tend to have fewer perfect rhymes.

First, let’s talk briefly about rhyme types. Perfect rhymes are pairs of words which have both final vowel sounds and final consonant sounds the same – e.g. space / race, moan / cone,  exemplify / diversify. Assonance rhymes have the same final vowel sound, but different final consonant sound, and the result is softer – e.g. lost / cough, graze / lake, policy / bakery.

The tricky part might be writing a song that minimizes perfect rhymes. Fast Car by Tracy Chapman comes pretty close, using mostly assonance rhymes to end her verses.

For my own song Hurting. Choosing. Learning, I managed to get through four verses and two choruses with absolutely no rhymes, and writing the verses as haiku poems to boot.

Three: Do a few songs in 3/4 or 6/8 time

This one is fairly common, but still, many songwriters fall back on the ubiquitous 4/4 time signature.

Before I get into examples, let’s go over what time signatures mean and how they work. Time signatures are normally expressed as two numbers (four-four, six-eight, or three-four). 4/4 time is sometimes called Common Time (go figure). The first number, or the one on top, is how many beats there are in one bar or measure. The bottom number represents the note division of the beats. So, if the bottom number is 4, the song is counted in quarter notes. If it’s 8, it’s counted in eighth notes (half the duration of a quarter note). It’s far less common to see a 2 for the note division.

For example, 4/4 time is counted as “1,2,3,4” in a moderate pace. 6/8 time is counted as “1,2,3,4,5,6” where each beat is about half the duration of the quarter notes. Of course, tempo plays a big part in exactly how fast the song is; the note divisions are relative to each other and also represent rhythmic emphasis—i.e. most of the time, there’s a strong emphasis on the “1”, otherwise known as the downbeat. In 3/4 time, the emphasis is usually on the 2 and 3, and in 6/8 time, the emphasis is usually on the 1 and 4. You can usually focus on the kick drum and snare drum hits in a song to indicate the stressed beats.

Compare the songs Wrapped in Grey by XTC and I Go To Sleep by The Pretenders. See if you can identify which is in 3/4 time and which is in 6/8 (hint: in the chorus of Wrapped in Grey, the snare hits on the “2” of every other measure).

Four: Treat your title differently

Many songwriters write from titles, which is a great way to get your song moving in a focused direction, and sticking to that focus. Sometimes the title is a phrase, at other times, a single word or pair of words.

Context is important here – does your title stand alone, or is it part of a larger phrase that maybe connects it with the verse or pre-chorus? Take note of your collection of songs; do you stick to one way of singing your title?

Consider Billy Joel’s song The Stranger. In this song, the “stranger” shows up frequently but it’s always part of a larger phrase in the verse. There’s a catchy “B” part which might be called the chorus, except that the title doesn’t show up there.

Contrast that with a song like Layla, where the title is the main hook (apart from the classic guitar riff), tops each chorus and melodically stands by itself.

Then look at the classic rock song Closer to the Heart by Rush; here the title is a full phrase that ends each verse in a verse-refrain structure (there is no chorus).

You can examine just about any song and note other ways in which the title shows up. Consider melody, narrative and what it might mean if the title was incorporated differently. For example, often when the title shows up as part of a larger context or phrase, the song is following a verse-refrain structure (see tip One above).

Five: Try a song with a quiet / small chorus

Where is it written that your chorus has to be the “big” part of your song? Typically, your chorus has a melodic center change to a higher, more expansive and catchy melody. But in Pretty Good Year by Tori Amos, the chorus is the most understated part of the song. The melody goes nowhere, it’s dynamically quieter, and very simple. The bridge is the section that takes on more characteristics of a chorus, expect the presence of the title and refrain (multiple repetitions in the song).

For a different example, check out the song Pretty by Miggs. The verse has a good amount of melodic range, and is fairly resolved. The chorus (“If it’s worth it..”) has more tension and less melodic range. Similarly to Pretty Good Year, it’s the C-section of the song that takes off with the catchiest, most energetic part of the song (“It takes a lot of steps…”). Call this part the post-chorus, maybe.

I took the “quiet chorus” approach when writing my own song, Brave DaughtersIn this case, the chorus lyric was more reflective and less direct than the angrier verse lyrics, so it led me to treat the music with a lighter energy.

Six: Open a song with your chorus

Opening your song with the chorus is a great way to give it a great kick off, particularly if your chorus is catchy and tight. This works usually when your chorus expresses the central theme of the song, and it doesn’t spoil anything to give it away up front. If you’re used to working in a double chorus at the end of your songs, this is an opportunity to keep that a single, lest you have too many choruses in your song.

A couple of good examples are We’re Not Gonna Take It by Twister Sister, and All About the Bass by Meghan Trainor. (Note: The song doesn’t kick in until over 2 minutes in We’re Not Gonna Take It, but that first couple of minutes is classic music video satire at its finest.) In both songs, the opening chorus is treated more like an introduction, with lighter arrangements than the full-blown choruses that come later.

Seven: Try a different mode in a song

I’ve saved the (arguably) most complex tip for last. Using different modes assumes you know about scales and key signatures, but after that, it’s fairly simple. Customarily, we begin a chord progression on the I chord of the key we’re playing in. But what about starting on the II chord, or III chord? Doing this imparts a subtle tension to your song, and especially works well if you resolve to starting your chorus with the I chord.

Try playing a major scale using the same notes but going from the II tone to the II tone. For example, the Dorian mode in C major would go like this:

D – E – F – G – A – B – C – D

You would also stick to chords in the base key signature. So in the the key of C major and the Dorian mode, this would mean you start your chord progression with a D minor. Famous songs in the Dorian mode include Scarborough Fair (made popular by Simon and Garfunkel), and Eleanor Rigby by the Beatles.

I tried this myself in a collaboration I did with my friend Shari Archinoff, called Winter Without You.

Note that the special, unusual chord progressions start with the II, III, IV, or V chord. It’s very common to start with the VI chord, known as the Aoelian mode or natural minor—just think of every song starting on A minor and using C major, F major, and G major.


You can also combine any of these tips into a single song. Please comment below about any of these 7 ways you’ve used, or about other tips you have for adding some variety to your collection of songs.

Winter Without You (with Shari Archinoff)

I met singer-songwriter Shari Archinoff at one of my meetup groups. Shari plays piano, guitar, sings, and lives in the same neighbourhood I grew up in.

The first time we met, I came up with a simple chord progression on the piano. Shari developed lyrics and a melody for a song about moving on from a relationship with a winter theme. We also threw in a little joke about the debate over the naming of Canada’s national bird. We completed a draft of the song in one afternoon.

Something I’ve been playing around with recently is trying to write in different modes. For the verse, I developed a chord progression in C major, but started the progression on D minor (the II chord). The mode reveals its slightly unusual nature when the G major chord turns up in the verse. Normally, if the song were in D minor, the IV chord would be G minor, but using a G major instead keeps the song in the key of C major, even though it doesn’t start with a C major chord.

A couple of weeks later, I had developed a more interesting chord progression for the chorus and some greater melodic interest for the piano verse part. Shari had completely re-written the lyrics with much greater attention to poetics and melody details.

We performed the song at a Songwriter’s Cafe Meetup in January. Feedback from the group was largely positive, and we ended up taking a suggestion to transpose the song a whole step higher. We found the higher key resonated a bit better with Shari’s voice.

We recorded the final version in my home studio. Shari added some wonderful melody variations to the final chorus.

It was a joy to work with Shari and we’re hoping to do some more writing together.

Nashville-style singer-songwriters in the round

Once again, I attended a night of talented singer-songwriters in a Nashville-style round, where four performers do four songs each in turn. What makes this kind of setup amazing is when the performers backup each other with guitar or harmony vocals.

The performers for the February 9 show at the 120 Diner in Toronto were:

  • Chase Stevens
  • John Chris Ford
  • Bruce Harrott
  • Annie Bonsignore

As before, I took some photos of the performers and shared the hi-res copies with them.

Nashville style singer-songwriters in the round photos

Once again, I attended a night of fantastic original music at the 120 Diner in Toronto. I was invited by two of the performers, Sherry Jacoby and Lora Ryan. The show was hosted by Annie Bonsignore and Roger Beckett from A&R Productions.

The great thing about the Nashville-style setup is the interplay between the artists. In particular, Augusta Ray lent her sweet country voice to other performers on stage. As well, Paul Malysa prompted the audience for random key words and improvised a song on the fly, with backup vocals by Augusta. It was a fun night and a privilege to hear such talented singers and songwriters.

I took photos of the performers, and offered to share high-resolution copies with the artists.

Relentless Turmoil – Loud Isn’t Loud Enough – mastering work

Last year I was approached by indie punk band Relentless Turmoil to master their latest album, Loud Isn’t Loud Enough. If you read anything about mastering on internet forums and what not, you’ll hear time and time again that it’s a strange black art. For a home studio based producer, it’s supposed to be an elusive task. But like most things when it comes to production work, the devil is in the details. Mastering is also about creative decisions just as much as it is about technical know-how, and most of the moves are quite subtle.

The process depends on what I’m mastering. For a single song, I consider overall tone, dynamics, and final volume. For an album of songs, I also consider sequencing, gaps between the songs, and relative volume between the tracks.

Sequencing and silence

Loud Isn’t Loud Enough is a unique album. Nine of the eleven tracks are full songs; one is a live track, and the last is a track of random “mess-ups.” The entire thing can heard in just over ten minutes. The shortest track is 22 seconds, and the longest clocks in at 1:33. There are great riffs and big energy to almost all the tracks. I decided to let some of the tracks overlap with each other, or leave no silence at all. I wanted to keep the album moving and energetic. The live cut and “mess-ups” track finishes off the sequence.

It’s been a while since I’ve heard an album that serves up a surprise final track. On the 1995 Tea Party album The Edges of Twilight, the final track, Walk With Me, clocks in at 14:20 with a five-minute song, a long silence, and an instrumental outtro. You’d never hear the instrumental bit if you stopped playback after the song itself, and maybe you only heard it if you forgot to stop the playback.

I brought a bit of this spirit to the final “mess-ups” track by adding almost 40 seconds of a buzzing guitar amp sound off the top, at a reduced volume. If a listener heard the album at a low level (who would ever do this with a punk record?), they might not even hear the buzzing and think the album was over, or they’d hear a very faint sound, turn up the volume, and be suddenly assaulted by the screaming band members a minute later. The band loved the idea and the way I did it.

Loud Isn’t Loud Enough

This is punk music. Punk is by its nature loud; like, your amp goes up to 12 kind of loud. Loudness is about more than the final mastered volume; it’s about the dynamic range. In other words, the difference between the loudest moment and the quietest moment in the song. The loudness wars aren’t about the maximum volume as much as they’re about the drastically reduced dynamic range.

Relentless Turmoil was clear in their directive – they didn’t want to squash the dynamics. They wanted the music to breathe with the beat and rock out like a classic punk or rock record. I fully agree with this approach, and I don’t believe you need to overdo the loudness in order to have a great energetic record.

Tone, dynamics, and final volume

I referenced a classic Sex Pistols record to achieve a similar tone for the Relentless Turmoil record. I adjusted each track with a little more “oomph” in the bass and a bit less harshness. The overall tone is warmer than the final mixes provided by the band.

Like the subtle moves to the tone, I also made adjustments to dynamics with subtle settings to overall compression and mutiband compression. For the final volumes, I hit the limiter a little bit harder.

Neither relentless nor turmoil

This album was great fun to work on. I don’t listen to a lot of punk music, but to me, any good music deserves the same attention to detail and care. The songs grew on me, and it’s a really fun album. Take a listen below and name your price on Bandcamp to download it.

Holiday Shopping Spree

Through co-hosting the Songwriter’s Cafe Meetup and Song Talk Radio, I get to meet many singer-songwriters in and around Toronto. Some of them have written original Christmas songs, including Carmen Toth’s This Christmas I’m Giving You Love and Melanie Peterson’s Santa’s Sleigh. Themes of peace and love tend to come up, as is typical of many holiday songs.

Of course, I try to be different. So, I wrote a song embracing consumerism and throwing playful jabs at the status quo of creative types. This is not to say I find typical holiday themes trite or tedious, but I do commend singer-songwriters who put their own special twist on these themes. In fact, it’s a tricky business writing a good original holiday song instead of playing cover versions of well established songs. Carmen and Melanie have done a great job with songs and performances that are sweet, thoughtful, and festive. It’s clear to me that I was inspired by these singer-songwriters to write this song.

Writing and recording the song

I wrote the lyrics over my lunch break one day, and the piano part after work. I did a quick demo recording and presented the song at the December Songwriter’s Meetup. A main critique of my song was that the holiday aspect wasn’t clear until the end of the chorus. I took the suggestions and revised the first verse lyrics, and wrote a new holiday-esque musical introduction with glockenspiel section. I also took a more deliberate approach to my melody, thanks to some suggestions from my singer-songwriter friend Melanie Peterson.

I recorded a final version, and then set to work creating a video. I spent about two hours at the Toronto Eaton Centre, listening to my recording on repeat and shooting footage of shoppers, interesting sale signage, and the latest big-screen TV’s at Best Buy.

During a Beige Shelter rehearsal, I asked our bassist Tom Kuczynski to record me playing the keyboard and singing the song. Tom’s also a talented photographer and videographer. I then edited together a quick video.

All in all, this was a quick and fun writing and recording process, with a push to get it done before Christmas. It’s amazing what you can pull off when you have a hard deadline to meet.

Lyrics

Your new greeting card
Peace and love for the holidays
I say good fortune for all
And dollars to spend on sales

You wrote that song
The evils of materialism
Give away half your guitars
To the needy and poor musicians

You know what
I like my stuff
Makes my life easy
You know what
It’s never enough
Holiday shopping spree

Always preaching moderation
Credit cards gotta stay at home
Support your local economy
Don’t be a consumer drone

You know what
I like my stuff
Makes my life easy
You know what
It’s never enough
Holiday shopping spree

Get what you want
Not what you need
You’d better like
What you got!

I only wanna spend
Christmas with you
Binge watching on Netflix
On my brand new
75-inch, L.E.D., 4K HD, and 3D
Smart TV with 1000 watt, 5.1 surround sound

You know what
I like my stuff
Makes my life easy
You know what
It’s never enough
Holiday shopping spree

Live music photography

I recently purchased a new medium telephoto lens for my camera and put it to the test with photographing a couple of live music events. I enjoyed a “songwriters in the round” event at 120 Diner in Toronto. I already knew three of the performers, and got to meet and hear several new ones.

Beige Shelter was playing a show at Skeaky Dee’s, and I took photos of bands The Thick, The Cashews, and singer-songwriter David Dino White. For this show, the stage was bathed in a very bad blue light, so I converted the photos to black and white in post-production.

For another Beige Shelter show, I took photos of supporting acts Brian Sasaki and Wilson & The Castaways. The show was a great success at the Amsterdam Bicycle Club in Toronto.

The new lens is great for capturing sharp photos in low light. I find the keys to great photos on stage are using spot metering and adjusting the focus point as you shoot. I like to capture high emotional moments in the performances and where possible, get them with their eyes open. Framing with odd angles also adds a cool dynamic.

How to shop for an audio interface

If you’re just starting out your home studio, or looking to upgrade your audio interface, there are many factors to consider in order to make an informed decision that gets you the best bang for your buck. An audio interface is the traffic cop of your home studio, controlling all the physical inputs and outputs.

Using an audio interface is always better for a home recording studio than the built-in soundcard on your computer. An audio interface:

  • will allow you to connect guitars, synthesizers, and professional microphones
  • can achieve lower latency, so you don’t hear a delay while recording or playing a software synthesizer
  • is designed to record and playback at the same time; a soundcard, not so much

With the right feature set for your home studio, you can improve your workflow and focus on the creative rather than the technical. Don’t get me wrong, though – you still have to understand the technical, so here we go.

Number of inputs

The first and potentially most important thing to consider is the number of inputs you have. You need as many inputs as things you’ll be recording at the same time. Interfaces generally come with 2, 4 or 8 analogue inputs.  Manufacturers usually state the number of inputs in the model name, and almost all of the time, it’s the first number.  For example, a Focusrite 2i4 has 2 inputs (and 4 outputs, but we’ll get to that in a bit). A Presonus AudioBox 44VSL has 4 inputs and 4 outputs.

What’s crucial to understand here is that you only need enough inputs for one recording pass. For example, if you record guitar first, then vocals, then bass, you really only need one input. If you’re recording all three at the same time, you’ll need three inputs. Simultaneous recording not only captures the magic of musicians playing off one another, but recording them on discrete channels also gives you isolated tracks in your software for better mixing. (Note, mic bleed is a topic unto itself.)

Types of inputs

Inputs for microphones are XLR inputs – an XLR mic cable has three large pins in a circle on one end. Often, audio interfaces feature “combo jacks” which can take an XLR (mic) cable, or a standard ¼” cable, like a guitar patch cord. Other inputs may only take a ¼” cable.

Inputs are usually designed for one or more impedance levels. The definition of impedance doesn’t matter – just note that microphones, guitars (or any stringed instrument with a ¼” output), and synthesizers all have different types of output, and require three different setting for inputs. Mic level is the weakest of the three, instrument level (for guitars) is higher, and line level (synthesizers, CD players, your mobile music device) is the strongest signal. While most combo jacks automatically detect a mic or line level signal, only some feature a switch or option for instrument level. Activating the instrument level switch (sometimes called Hi-Z), if it’s available on your interface, ensures you get a good signal level from the instrument. This is about the same as patching your guitar through a DI box.

Input channels may also features a 20dB pad. This switch cuts the signal by 20dB, which is a significant drop. This is useful if you’re recording anything particularly loud, like a guitar amp or a drum, and ensures you won’t distort the signal. This feature is usually not found on the least expensive interfaces.

Some interfaces also include 5-pin MIDI input and output. While not strictly part of the audio system of your home studio, this can save you from investing in an additional USB MIDI interface if you have some older synthesizers you want to use. Most modern synthesizes and MIDI controllers connect directly to your computer via USB.

Preamps

When you plug in a microphone, the gain knob controls the volume of the input and engages the preamp. Ideally, these knobs are laid out beside each input, so it’s easy to know which knob controls which input. For most home studio setups, the preamps in modern audio interfaces are low-noise and transparent sounding. While some interfaces feature premium quality preamps (for a premium price), you need to keep in mind you should also have a premium microphone and an acoustically treated recording environment to really take advantage.

Phantom Power, or 48V

Every audio interface will have a switch or button for 48V power, also known as Phantom Power. This is required for using condenser microphones. Just remember to always switch on Phantom Power after plugging in your microphone, and switching it off before unplugging your mic. Phantom Power will not affect your dynamic microphones.

Some interfaces put the switch for 48V on the back of the interface. Ideally, the switch is on the front and has a light to indicate that it’s on. Some may even have the switch as part of the software interface, which in my opinion, is the least desirable place for it.

Outputs

Most audio interfaces will have balanced TRS (tip, ring, and sleeve) connections for outputs. The TRS cable looks similar to a ¼” patch cord (unbalanced TS cable), but it has an additional ring on the connector pin, indicating that it can be used for a balanced TRS connection, or carries a stereo signal, like your headphone cable. Generally, balanced TRS connections are less susceptible to introducing hum or noise in your signal path over longer distances.

Outputs are normally reserved to connect your studio monitors. This takes two outputs – one for the left speaker, one for the right. Interfaces with more than one output pair can be used to connect additional speakers, or connect to a desktop mixer. Connecting to a second set of speakers can be useful in testing your mixes.

Don’t discount the value of a big honking volume knob. Some interfaces feature this, and personally, I think it’s a great value add. Volume of your playback is one of the most frequently used controls in your home studio, and sometimes you need to adjust it quickly; you don’t want to be mousing around to find the control. Some interfaces also feature a mute button, which is ideal (i.e. you don’t want your monitors sounding while you’re recording from a microphone).

Digital inputs and outputs

Some interfaces also include digital inputs and outputs. These are used if you have a device with a corresponding output (S/PDIF or optical). The optical (sometimes called ADAT) signal can carry 8 discrete channels. For example, you could expand your two-input setup with an 8-channel preamp with an optical output, for a total of 10 microphone or instrument inputs. The S/PDIF connection only carries a 2-channel stereo signal, and is usually found on synthesizers or CD players.

Sometimes audio interfaces are marketed as having 10 inputs, while only two mic inputs are visible. That’s because the manufacturer is also counting the 8 digital inputs via an optical connection.

Monitoring options

All interfaces have an option for zero-latency monitoring. Generally, if you want to include a reverb in software for your vocalist while recording, you’ll introduce latency while the computer processes the signal, applies the reverb, and sends it back out to be heard. A zero-latency switch (often called direct monitor, or input) allows you to hear the input in real time, without latency, along with the computer playback. Some interfaces allow you to adjust the relative levels of input and playback material.

On-board DSP

Some interfaces include on-board digital effects processing. This allows you to record with very low latency and still apply a reverb or other effect to the monitored input. In my opinion, this is only an issue with older or very budget-level computers. With most modern systems and non-DSP audio interfaces, you can get latency down to a few milliseconds and use a software reverb. It’s best to use a low-CPU taxing plug-in for this. It’s important to note that the reverb in this case won’t be recorded; it’s only used for monitoring. You can still use a better reverb plug-in after the recording is complete. Many singers prefer a bit of reverb in their headphones while recording.

Power supply

Many of the two-channel interfaces are powered by their USB connection to your computer, making them ideal for a mobile recording studio. The larger interfaces, with four or more inputs, usually require a separate power supply in addition to the USB connection, and a power switch. This is something to consider if you’re planning to go mobile with your studio.

Bundled software

The fact is, there are a lot of interface options out there, especially in the two-channel range. One way to decide which one to buy is to look at their bundled software. Many manufacturers include a light version of recording software, like Cubase or Abelton Live. If you prefer one software choice over another, but you haven’t invested in it yet, sometimes getting the light version with your interface gives you a discount when upgrading to the full version. You can check with the software companies to find out more, or download trial versions if you haven’t settled on one yet.

Conclusion

Ultimately, I can’t tell you what interface to buy. If you want to know which one I have, and which ones I’ve had in the past, check out my blog post about the history of my home studio. You have to assess your needs and come to your own conclusion. Hopefully, this article has armed you with the knowledge to make a good choice.
