How to add a chorus

1. Drop an audio file you already have. A video is refused here. 2. Leave light, or pick medium or wide. 3. Press “Add chorus” and download the same file type.

GustKit runs the FFmpeg chorus filter. Light uses one short voice. Medium uses two. Wide uses three. MP3, WAV, M4A, OGG and FLAC keep their type. The clock time stays about the same.

A short delay, not a room

Bass and treble change a shelf. Change volume raises or lowers the whole file. This page mixes a delayed copy that moves a little. It does not add a long room reverb. A video belongs on the video pages.

The audio stays in this tab

FFmpeg runs in this browser. GustKit does not fetch audio from a link. Close the tab and the file is gone. Audio up to the limit shown next to the button.

How to check the chorus

1. Play the download next to the original. 2. Light should sound a little doubled. Wide should sound thicker. 3. If the file type changed, you opened a different page.
