AudioIQ

About

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.
