Plugins don't fix a mix; your ears decide what to change. Producers who can name "that's 300 Hz mud" or "the vocal is over-compressed" mix faster and better. That skill is trainable, the same way musicians train to recognise intervals. There are two kinds of ear training:
- Technical (audio) ear training: hearing frequencies, EQ boosts and cuts, compression, panning and reverb. This improves mixing.
- Musical ear training: hearing intervals, chords and scales. This improves writing, melodies and playing by ear.

A 10-minute daily routine
| Minutes | Exercise | Why |
|---|---|---|
| 0 to 4 | Frequency game: identify boosted bands (start with octave bands, then thirds of an octave) | Learn where mud, boxiness and harshness live |
| 4 to 6 | Compression or dynamics game | Hear when a sound is squashed or pumping |
| 6 to 8 | Panning or reverb game | Judge width and depth |
| 8 to 10 | Intervals or chords | Write and play by ear |
Do it before you mix, at a moderate volume, on the same headphones or speakers you mix on. Short and daily beats long and weekly.
A frequency map to train against
| Range | What it sounds like | Common problem |
|---|---|---|
| Below 60 Hz | Rumble, sub bass you feel | Muddy low end on small speakers |
| 60 to 250 Hz | Weight and warmth | Kick and bass fighting |
| 250 to 500 Hz | Body | "Mud" and boxy vocals |
| 2 to 5 kHz | Presence, clarity | Harshness and listening fatigue |
| 5 to 10 kHz | Sibilance, attack | Harsh "s" sounds |
| Above 10 kHz | Air, sparkle | Brittle cymbals |
Then use it on real mixes with our mix troubleshooting table and a free analyzer from our free plugin list to check your guesses.
Train for free in your DAW
- Put an EQ on a song you know well, boost one band by 6 dB and ask a friend (or a random-preset button) to choose the frequency.
- Guess, then check. Repeat with cuts, which are harder to hear.
- Do the same with a compressor: set a random threshold and guess how much gain reduction you hear.
Questions people ask
Does ear training really improve mixing?
It helps you recognise what is wrong faster: which frequency is muddy or harsh, and when compression is too heavy. Combine it with reference tracks and an analyzer to confirm what you hear.
What is the best ear training app for producers?
SoundGym focuses on audio skills such as frequencies, compression and panning. TrainYourEars is a one-time purchase focused on EQ. musictheory.net is free for interval, scale and chord training.
How long does ear training take?
Most apps are built around about 10 to 15 minutes a day. Consistency matters more than session length.
