How to remove silence of an mp3-file?

[Pouckypluysch]

I'm working on a little project where I'm asked to make some loopable music to play under a looping animation. I created a track, and made it so that it can be repeated without an audible end/start point. But when I convert the wav (in Wavelab) to mp3 (the preferred audio format) there is automatically a few milliseconds of silence inserted at the beginning and at the end.

I can remove these silences, but when I re-open the file, the silences are inserted again. The silences make the end/start point audible, so I want to get rid of them. How do I do that?

This is a limitation of mp3 files. For perfect loops, you'll have to use another format.

Or just loop the track for like 10h and then make an mp3 out of it.

If it's a 44.1khz, 128kbps MP3, then each frame is 417 samples long. Make sure your loop is an exact multiple of that, and everything should be fine.

Ogg Vorbis is gapless. Might want to give that a go.

Use Ogg's... they don't insert some silence at the beginning...

In fact when ever collabarating with other it's best never to use mp3's because of this insertion of silence problem.

amazingly Ogg Vorbis is not a baddie from Blake's Seven.

.OGG or wave wrapped in OGG, this means it's a compressed file like an ogg, but reads as a wave.
