How it works
About Audio Equalizer
The Audio Equalizer reshapes the tone of a track with one-click presets or your own bass and treble settings. Presets cover the common jobs — bass boost, bass cut, treble boost, bright and crisp, vocal clarity, podcast polish, and a loudness curve that lifts both ends — while custom mode gives you bass and treble gain controls up to ±12 dB.
A live preview plays your file through the EQ in the browser: switch presets while it plays and toggle the effect on and off to compare against the original, with a curve display showing exactly what changes. The in-browser preview is an approximation; the final file is rendered in full quality on the server.
Upload MP3, WAV, M4A, or OGG and download the equalized MP3. The tool is free — a fast way to add warmth to thin recordings, tame boomy bass, or give spoken word a broadcast-style polish.
