Train your ears. Mix better.
$4.99 · Designed for iPad. Not verified for macOS.
Ear training built for audio engineers, not musicians. Practice EQ, compression, distortion, reverb, and more on real recordings. 11 modules, all free-play labs included.
Audio IQ is ear training built for audio engineers.
Instead of intervals and chords, you practice recognizing what actually matters in a mix: EQ moves, compression, distortion, reverb, delay, phase issues, limiting, saturation, loudness differences, and codec artifacts. Every exercise plays real recordings, never synthesized test tones, across dozens of genres — classical, jazz, military band, folk, world music, and more.
ELEVEN MODULES
EQ — spot the boosted or cut frequency band
Compression — tell apart subtle, moderate, and hard-squashed dynamics
Distortion — recognize overdrive, fuzz, digital clipping, and bitcrush
Loudness — judge level differences by ear, in dB
Reverb — tell room, hall, plate, and cathedral apart
Delay — judge how long the echo repeats are
Noise & Artifacts — spot hum, hiss, clicks, and pops
Phase & Mono — hear a mix collapse in mono or cancel out of phase
Limiting — feel the difference between compression and a brickwall ceiling
Saturation — dial in warmth from clean to hot
Codec Artifacts — recognize what a mix crushed to a low bitrate sounds like
PRACTICE + LESSONS
Every module has two modes: a multiple-choice Practice quiz to test yourself, and a free-play Lesson lab with live sliders so you can explore each effect at your own pace before or after quizzing.
BUILT TO FIT YOUR LEVEL
Set difficulty once in Settings — Beginner, Intermediate, or Advanced — and it applies everywhere, narrowing the gaps as you improve. Track your accuracy and daily streak per module, right on your device.
