Ear training for mixing

Know what to listen for.
Actually hear the difference.

When you are learning to mix, the hard part is often knowing what to listen for. Explore the difference with labelled examples, then tell it apart without hints. Difficulty follows your answers.

FREQUENCY· LISTENING ROOM

Is anything different?

Switch between the reference, the boosted and the cut example. All three sit at the same Low frequency.

Compare body, boxiness and brightness. Where is the change?

01Listening rooms

Before the right answer,
listen for the right thing.

Before every stage a listening room opens, with no score. Play the reference and the labelled examples side by side, switch the material and see where the difference sits.

When you are ready, move on to the exercise — assessment starts there.

  • Guided discovery or free comparison
  • Hands-free A/B that cycles through the examples
  • Your listening note stays on this device
So what do I practise after that?

02Guided curriculum

Not random games.
A path you can follow.

Every skill has its own stages. First you hear that something changed, then where it changed, then how precisely you can place it.

A stage opens when you answer correctly often enough at the target difficulty — not after a fixed amount of time.

FrequencySample progress
  1. Is there a change in the Low band? done
  2. Is there a change in the High band? done
  3. Which band is the EQ change in? done
  4. 04 Is there a change in the Mid band? Evidence 8 / 12 now
  5. 05 Which band was changed? next
  6. 06 Which part of the Low band was changed? later

+3 more stages

At the target difficulty a correct answer adds 1 and a miss takes 2 away. At 12 the next stage opens.

03Adaptive difficulty

As your ear improves,
the differences get finer.

Exercises adjust to your answers: get it right and the difference shrinks, miss it and it becomes clearer again. The aim is not to keep you winning or struggling, but to keep you where you get roughly four out of five right.

That is why your accuracy percentage does not show progress. A shrinking difference does.

04Progress tracking

Not just a score.
The direction you are moving in.

When you play with an account, every skill gets its own progress screen: the difficulty you have practised over time, the material you hear more easily, your practice pattern and a suggestion for what to do next.

Seventeen skills · one way of learning

Hear the different layers of a mix.

Each skill starts with one simple question.

  • Panning Is the sound on the left, in the centre or on the right?
  • Compression What happened to the hit and to the tail after it?
  • Stereo Width Does the sound feel narrow or wide?
  • Frequency Which part of the sound changed — its body or its brightness?
  • Gain Is one sound louder than the other — and by how much?
  • Masking Which sound is covering up the other?
  • Sidechain Ducking Is the bass making room for the kick?
  • Phase & Polarity Are two copies cancelling each other?
  • Reverb How far back does the tail put it?
  • Delay How many repeats, and how far apart?
  • Balance Memory Which fader moved in the mix you just heard?
  • Reference Match Where do these two mixes differ?
  • Mix Critique No reference — can you name the flaw?
  • Chain Order Same two plugins: which one came first?
  • Saturation Is it saturated — or just brighter or louder?
  • Tone Vocabulary Muddy, boxy or harsh — can you name what you hear?
  • Spectral Balance Is the mix dark, bright or balanced?
  • Filters Was it cut from below, from above — and where?
  • Resonance Hunt Where does this sound ring on its own?
  • Multiband Compression Which band of this mix is squeezed?
  • Transient Shaping Did the hit get sharper or longer?
  • Gate & Expander What did the gate remove — and what did it break?
  • Loudness & Limiting How hard is this master pushed — and what did it cost?

Hear better. Mix with intent.

In your next mix,
know what you are hearing.
