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. PRIVACY FIRST No account, no ads, no tracking. Your progress lives on your device.
