Audio equalizer online for free
Adjust 10 bands from 31 Hz to 16 kHz, or start with a preset such as “Bass boost” or “Voice clarity”. You hear the change live while you move the bands and can compare it with the original. A limiter keeps the result from clipping when you boost the bass.

Audio equalizer: common questions
Which band do I raise for more bass?
The 62 and 125 Hz bands add body; 31 Hz is only noticeable on large speakers or headphones. Lower the output a little to avoid clipping.
Why does the volume drop when I pick a preset?
Some presets lower the output to leave headroom: boosting bands raises the peaks, which could clip.
Does it change the original file?
No. A new file is created on your device; the original stays as it is and is not uploaded anywhere.
Is my audio uploaded to a server?
No. The tool runs inside your browser: audio files are read and processed on your device and are not sent to Cocuyo or to any third party. The MP3 encoder is served from our own site. You can check it in your browser’s network tools: your file is not sent.
Is it really free?
Yes. You can try it before signing up; to download the result we ask for a free account, with no subscription. Your free account comes with 30 welcome uses; after that, each use costs 1 credit (top-ups from US$1), and they are unlimited with Basic or Pro. It never adds a watermark.
