Give a song, a jingle or a recording a soft start and a gentle ending instead of an abrupt cut. Set the lengths, pick a curve, and apply it to one file or a whole batch.

How to fade audio
- Choose or drop one or more audio files.
- Set the fade in and fade out in seconds (0 for none).
- Pick the curve: smooth for music, linear or logarithmic.
- Press Apply fades, listen, then download or send the files.
Which curve to use
| Curve | Sounds like | Good for |
|---|---|---|
| Smooth (sine) | Even, natural fade | Music, most uses |
| Linear | Level drops slowly, then quickly at the end | Short fades, sound effects |
| Logarithmic | Steady fall in decibels, like turning a volume knob | Long fade outs |
Typical lengths
- Removing a click at a cut: 0.1 to 0.5 s.
- Song intro: 1 to 3 s.
- Radio-style ending: 5 to 10 s.
To cut a section first, use Trim audio, which also has fades. For a ringtone with fades, use Ringtone maker.
Quality and privacy
Fading changes the samples, so the audio is decoded and encoded again: choose 192 kbps or more for music, or WAV to keep it lossless. It all happens in your browser, and the files are not uploaded.

Yes. Set the fade in to 0.
Can I fade several files at once?
Yes. The same fades are applied to every file; download them as a ZIP.
Does fading lower the quality?
The audio is re-encoded once. At 192 kbps or more, or as WAV, you will not hear a difference.
