Fade audio in and out
Ease a track in at the start and out at the end instead of cutting it off.
A track that starts at full volume and stops dead sounds like a mistake, and it is the difference between a clip that sounds finished and one that sounds cut. Set how long each fade should take; the end is found from the file itself, so you do not have to work out where to put it.
How to use it
- Add the audio file.
- Set how many seconds each fade should take.

Frequently asked questions
- How long should a fade be?
- One to two seconds at the start and two to four at the end suits most music. For speech, half a second at each end is plenty — a long fade on a voice sounds like a fault.
- Can I fade only one end?
- Yes. Set the other one to zero and it is left alone.
- Does the file get re-encoded?
- Yes, because the volume of the actual audio is being changed. If you set both fades to zero nothing is altered and the audio is copied straight through instead.
- Why is the result always an MP3?
- Because it is the format that plays everywhere, and a file that has just been faded is usually about to be sent to somebody. Use Convert audio afterwards if you need a different one.
