Über dieses Tool
Add a smooth fade-in at the beginning and/or fade-out at the end of an audio file. Removes the abrupt clicks at the start of recordings and the harsh cut-offs at the end, giving voice memos, music demos and podcast intros a professional finish in seconds.
Privvert lets you set independent fade-in and fade-out durations in seconds. Fades use a linear curve by default, with an optional logarithmic curve for music. Stream-copy is preserved for the unchanged middle of the file when possible, so processing is fast.

Häufig gestellte Fragen
Yes - set the duration on the side you don't want faded to 0.
0.05-0.2 seconds is enough to remove a click. 1-3 seconds is a typical music fade. 5+ seconds for a slow ambient ending.
No - fades only adjust the volume curve at the edges. Use the silence-removal tool to trim leading/trailing silence.
Output is MP3 at 192 kbps regardless of input, so the file plays everywhere.
Human hearing is roughly logarithmic, so a mathematically linear amplitude fade sounds like it stays the same volume and then suddenly drops. The default fade curve is logarithmic for that reason; you can switch to linear if you specifically need it.
For songs, 2-4 seconds at the end is conventional. For voice recordings or podcasts, 0.5-1 second on the intro and outro is usually enough to avoid clicks without sounding faded.
