Hi thanks, indeed it works -- but mplayer changes the pitch (sounds like mickey mouse on speed up). The yatm changes the speed without changing the pitch, so it still sounds natural even on faster speed.

It's substantially below realtime, IIRC, but sox can do it for general sound files with the standard windowing, time-scaling, and overlapping.
If you only want mp3s, and are content with ratios of small integers (so it can be done by just repeating and dropping mp3 frames), mpg123 can do it for mp3s with -d and -h, and should have almost no penalty.

I found it in a new version of mplayer:
https://launchpad.net/~rvm/+archive
* the option to change the playback speed without altering the pitch will work (thanks to the new scaletempo filter)
It does not work in maemo mplayer rc1.2. Any body knows where I can get a version with this scaletempo filter ?
EDIT: Here are the scaletempo patches to mplayer rc1.2:
http://sourceforge.net/project/showf...kage_id=279916
Any body kind enough to patch it and make it available for everybody? Thank you in advance!
