EQ Ear Trainer

Most producers can hear that a mix sounds wrong. Far fewer can name the frequency.

EQ Ear Trainer closes that gap. The app hides a boost somewhere in the spectrum, you guess where it is, and then it plays the answer back so your ear learns the difference. Two taps from opening the app to your first exercise. No setup, no account, no tutorial to sit through.

HOW A SESSION WORKS
Ten rounds. Each one hides an EQ change at a single frequency band. Hit bypass as often as you like to compare against the flat signal, then pick the band you think it is.

Miss it, and the correct band keeps playing so you can A/B it against the one you chose. That comparison is where the learning actually happens — it is the difference between a quiz and real training.

FOUR LEVELS
Basic — 8 octave bands, +6 dB, boosts only.
Intermediate — 8 bands at 4 dB, and now cuts as well as boosts. A cut at 250 Hz does not sound like a boost at 250 Hz.
Advanced — 15 half-octave bands at 3 dB. Neighboring bands sit much closer together.
Precision — no multiple choice. Turn a one-third-octave knob until your attempt matches the target, and you are scored on how close you landed, measured in octaves.

EXPLORE MODE
New to this? Explore lets you tap through the spectrum with no rounds and no score, so you find out what 250 Hz actually sounds like before anyone tests you on it. Most ear training apps drop you straight into the exam. This one lets you listen first.

YOUR EAR PROFILE
The app tracks your accuracy for every frequency band and turns it into a profile: which bands you nail, which ones you keep missing, and where you are improving. Daily streaks included.

TRAIN ON MUSIC
Pink noise is the fairest place to start, because every octave carries the same energy and no band is easier than another. When you are ready, switch to a synthesized drum and bass loop and find the same boosts in a musical context. It is a noticeably different skill, and it is the one you use when you mix.

WHAT YOU WILL NOT FIND
No banner ads eating the screen. No interstitials interrupting a session. No account, no sign-up. Every exercise runs offline, and your progress is stored on your device.

The only ads are optional reward videos you choose to watch, and they never take anything away from what is already free.

USE HEADPHONES
This matters more than it sounds. Phone speakers reproduce almost nothing below 400 Hz, which makes the three lowest bands inaudible and the exercise unfair. Any headphones will do the job.
