Runs in your browser. Your files are never uploaded. How it works
Drag across the waveform to select, or type the times.
Fade In and Fade Out Audio makes a song or recording start and end smoothly instead of with a jump. It opens with a 3 s fade in and fade out over the whole file; change either one from 0.5 to 10 seconds, or set it to None. Click Apply fade, listen, and save as MP3, WAV, M4A, FLAC or OGG.

Fade a part of the track
The whole file is selected when it opens. To keep only a section, drag across the waveform or type From and To: the fades are applied at the start and end of that section. For a ringtone with a fade, see the Ringtone Maker; to blend two songs into each other, use the crossfade option in Audio Joiner.
Frequently asked questions
How do I fade out the end of a song?
Choose the file and set Fade out to the length you want, for example 5 s; set Fade in to None if the start should stay as it is. Click Apply fade, listen, then download.
How long should a fade be?
1–2 seconds removes a click or an abrupt start. 3–5 seconds is a natural fade for music. 10 seconds is a long, radio-style fade out at the end of a song.
Can I fade only part of a song?
Yes. Drag across the waveform or type the From and To times: only that part is kept, with the fades at its start and end. This is how you fade a clip cut out of a longer track.
