How Equalizer and Bass Boost works

The live preview uses Web Audio filters, so slider changes are heard instantly. The export applies the same 10 bands with ffmpeg equalizer filters plus a limiter.

Input: MP3, WAV, M4A, OGG, FLAC, MP4, MOV, WEBM. Output: MP3, WAV, M4A, OGG, FLAC, MP4, MOV, WEBM.

How to use Equalizer and Bass Boost

1. Drop a file and press Play.
2. Pick a preset or move the sliders while it plays.
3. Export the equalized file.

Tips

• WAV is lossless but large; MP3/AAC/OGG are compact for sharing.
• Engines load on first use and are cached afterwards.

Equalizer and Bass Boost FAQ

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
