Audio Equalizer

Apply a 10-band graphic EQ to audio entirely in the browser. Drag-and-drop or pick a file, decode with Web Audio API, adjust the gain (-12 dB to +12 dB) on each ISO-standard band (31, 62, 125, 250, 500, 1k, 2k, 4k, 8k, 16k Hz), apply via a chain of peaking BiquadFilterNodes in an OfflineAudioContext for batch processing, and re-encode as a 16-bit PCM WAV (pure-JS encoder). 10+ preset library (flat, bass-boost, treble-boost, vocal-boost, loudness, rock, pop, jazz, classical, podcast), 3-band & 5-band simplified modes, 7 gain presets per band, default Q factor 1.41, gain validator, filter-chain config builder, file-size estimator, text + CSV report, history (localStorage), shareable URL, summary stats. 100% client-side.
