Add Reverb to Audio

This page adds reverb to an audio file. Drop in an MP3 or WAV and Audjust applies reverb that gives the sound a sense of space, as if it were recorded in a room, a hall, or somewhere bigger. It runs in your browser, it's free, and there's no signup or install.

To do it: open the studio and upload your file. Apply reverb to the track. Listen back on the waveform, adjust how much you want, and export when it sounds right.

People usually land here to fix a thin, dry recording, like a voice memo, a phone-recorded vocal, or a flat instrumental that sounds bare. Reverb fills that empty space. Others want to give a song they like a roomier, more open feel.

One thing worth knowing: a little reverb goes a long way. Too much and vocals get muddy and words blur together. Start light, then add more only if it still sounds dry. You can also trim or rearrange the track in the same studio before exporting, so you're not jumping between tools.

A lot of people ask whether they need software for this. You don't. Everything happens on this page, and your finished file downloads straight back to you.

If you want a slowed-down, dreamy version instead, that combination has its own page on the site. This one keeps reverb at the track's normal speed.
