Audio ear training
for working engineers.
Tools and references for the decisions you make on a mix: which band, how much compression, whether the speakers are telling the truth. Every page plays audio. None of them is a keyword swap of its neighbor.

Drills, then the references that explain them
Train first, then look up the band you could not name. The chart and the instrument pages use the same stems as the drills, so a frequency you find in practice is a frequency you can replay in context.

FAQ
Audio training questions
I am new to EQ. Where do I start?
Do ten minutes on the frequency trainer with pink noise, then open the EQ chart and solo one band on a drum loop. After that the kick, snare and vocal pages will make more sense.
Is this the same training as the app?
The web drills are free and shorter. The iOS app is the daily practice: more stems, a streak, and units that come back when you miss them.
How loud should I listen?
Keep these drills at a conversation level. These pages can generate steady tones and noise, which fatigue your ears faster than music. If anything rings or feels uncomfortable, stop and turn the volume down.
