Hear it
A band gets boosted, a compressor clamps down, one part creeps up a few dB. Flip it in and out until you hear what changed, then name it. In EQ, sometimes nothing changed at all.
Train your ears to hear what most people miss: the frequency muddying a mix, the compressor flattening the drums, the vocal sitting a touch too loud. A few minutes a day trains you to hear it before you reach for a plugin.

Flipping by itself. Tap one to take over.
Every exercise trains part of the same flow you use on every mix: notice a change, track down what caused it, then put it right without hurting everything else.
A band gets boosted, a compressor clamps down, one part creeps up a few dB. Flip it in and out until you hear what changed, then name it. In EQ, sometimes nothing changed at all.
Something is ringing, poking out or sitting too loud. Sweep a boost across the spectrum until it jumps at you, or pick out the part that moved.
Cut it on the right instrument, or set the faders back where they were, in a full mix. Your score is how close the result gets to right.
Use headphones or decent speakers. Laptop and phone speakers can’t play the low bands, so 63 and 125 Hz turn into guesswork.
Start with EQ: name bands on pink noise, then find the one instrument muddying a full mix. Then hear what a compressor is really doing, and set a song’s faders by ear. Every exercise has levels that get harder as you go.
Hear it, find it, fix it.
Stop guessing. Start hearing.
Set the faders by ear.
Pan, width and reverb by ear.
Ear training works the way practice does: a little, often. Mix Chops keeps score so you can see it working.
Twelve questions from pink noise to a full mix, weighted toward the bands you miss. Keep the streak alive and post your score.
Take today’s sessionMix Chops keeps your first answers at every band. Keep training and your latest show beside them, so you can see what’s changed.
An illustration, not real results. Yours fill in as you train.
Every right answer is XP. Climb eight ranks, from the studio runner up, and collect badges along the way. Golden Ears is a Pro rank: it also takes the last level of Identify, Compressed or Dry and Restore the Balance, and those are Pro levels.
“We all hear changes that aren’t there. I’ve tweaked a bypassed EQ and sworn it sounded better.”
Dan Murtagh, in the feedback for a No change questionThe daily session and the first levels of two exercises in each of EQ, compression and balance are free for good. Pro opens every exercise and every level, Space, your own songs and the whole track library.

Dan Murtagh has been making records in Melbourne for 20 years and has taught audio production at Collarts since 2016. Every exercise, hint and explanation in Mix Chops is written the way he teaches: in plain words, around what you actually hear on each instrument.
Short explainers and practice guides with a demo you can play: flip each move off and on, then practise it in the exercise that goes with it.
What an equaliser does to a sound, on a full mix: a range of frequencies turned up or down.
Hear itPlay each of the nine bands boosted or cut, on noise and a mix, and learn a name for every one.
Hear itFrequency, gain and Q, the three controls on every bell band. Hear what each one does.
Hear itTake out everything below or above a point. Where a high-pass goes on a vocal, and when it goes too far.
Hear itLift or lower everything above or below a frequency, and how a shelf differs from a bell and a filter.
Hear itMuddy, boxy, honky, harsh, sibilant and dull: what each sounds like and where to look for it.
Hear itIt turns the loud moments down. Hear it on drums with the levels matched, so louder is never the clue.
Hear itIt works if you know what your headphones hide. Check the low end, then train on what you mix on.
Hear itHeadphones or decent speakers. Laptop and phone speakers can’t reproduce the low bands, so 63 and 125 Hz turn into guesswork. Set a comfortable level on the first sound and leave it there: every exercise plays at the same loudness.
Yes. The daily session and the first two levels of two exercises in each of EQ, compression and balance are free, with no account and no card. Until Pro launches, every exercise but the Pro-only ones is open to everyone, every level, and accounts made before launch keep them.

Anyone who mixes: students, producers, bands recording themselves, and engineers keeping their ears sharp between sessions.
Mix Chops trains EQ, compression, balance and space in your browser, and it goes past naming bands to fixing the problem in a full mix: cutting the instrument that’s muddying it, or setting the faders back by ear. See how it compares with SoundGym and seven other ear trainers.
Three sounds, a minute or two: hear what your ears already catch, then train the rest.
