Fade in / out

Bring a recording in gently and let it fade out naturally.

Every parameter, explained

Fade in

0 ms to 10000 ms · Default 1500 ms

Time for the opening to rise from silence to its original level. Set to zero to keep the original beginning.

Fade out

0 ms to 10000 ms · Default 2000 ms

Time for the ending to fall smoothly to silence. If both fades exceed the track length, they shrink proportionally.

A good place to start

Try the sample or upload a short recording. Apply the defaults, compare Original and Result, then adjust one parameter at a time. Revisions on this page start from your original recording.

What to listen for

Fade times are scaled together if they exceed the recording length. Duration is preserved.

Compare a quiet passage and a busy passage at a comfortable listening volume. The player volume changes playback only; it does not change the downloaded audio.

Can I combine this with other effects?

Yes. Open the combination studio and choose this effect along with any others. Effects run in the displayed order, and completed stages are reused. Changing or removing an earlier effect rebuilds the affected stages.

Once processing finishes, compare the result and download MP3 or WAV. MP3 encoding runs locally and does not apply the effects again.
