How to equalize audio online
Open a song, podcast, or recording and turn its bass, middle, and treble up or down by up to 15 dB, or start from Clear voice, Brighter, or Less bass. Save it in its own format. A limiter keeps a boosted band from clipping, and a video's sound changes under its picture. It runs in your browser, so the file stays on your device.

What to expect
- Supported inputs
- MP3, WAV, M4A, AAC, FLAC, OGG, Opus, AIFF, and other audio files, and videos (MP4, MOV, MKV, WebM) with sound.
- What happens
- Three bands: a bass shelf below about 100 Hz, a middle band around 1 kHz, and a treble shelf above about 8 kHz. A boosted file is held under -2 dBFS so it doesn't clip, then saved in its own format (FLAC as WAV).
- Limits
- Three bands, not a graphic equalizer with ten. The change is applied to the whole file.
