How to Add a Fade-Out to Audio Online
A fade-out lowers the volume at the end of a recording. Use it to ease a voiceover into silence, tidy a sample, or soften an ending that stops too suddenly.
You can do this in Audio Lab FX Editor in your browser. Keep your original file so you can return to it.
1. Open your recording
Choose Audio and select an audio file your browser can open. You can also start with a new microphone recording. If your file cannot be decoded, try a WAV version of the source.
Need a file to practice with? Download this original four-second tone. It was made for this tutorial; you can use and edit it freely. It ends abruptly so the fade is easy to hear.
2. Choose where the recording ends
In the editor, open Edit, then Trim if you need to shorten the recording. Listen to the ending before changing the fade. A fade changes the level; trimming changes which audio you keep.
3. Adjust Fade Out
Under Edit, open Fade and increase Fade Out. Start with 0.5 seconds, then try a little more or less. The control supports up to two seconds. For a very short clip, use a shorter fade so it does not swallow the whole ending.
4. Listen to the last few seconds
Play through the end. The recording should taper into silence without cutting off a word or note you wanted to keep. If it disappears too early, shorten the fade. You can use Undo to compare with the earlier edit.
5. Export the result
Choose Export to prepare the processed audio as a WAV file. Complete the download or save action shown by your device. Play the exported file to check the ending before using it in your video, podcast or song.
Audio Edits also save locally on this device. Check that saving succeeds; clearing browser storage can remove local-only projects. Export a copy of anything you want to keep. Signed-in users can separately choose Sync to cloud from Projects. Video edits need to be exported before leaving.
Try one more change
A short fade-in can soften the start of a recording too. If the ending feels dry rather than abrupt, try a small amount of reverb and listen again. Additional effects and mastering controls may require Full Access; stem separation uses Stem Credits.
