[MPlayer-users] Resamplig of audio

Hi,

I had a look at SDL, their resampling is a joke (it can only do 2 up or
down and has no filtering) nice documentation though. I made some
Matlab simulations using a FFT-DFT based approach but I haven't got
anything solid yet (bloody thing still clicking - I will try with
overlap and add). If I get lucky and find something that works I can
make a C implementation. It will be slow as hell - MMX/3DNOW will be
necessary. I heave worked quite a bit with assembly but only on DSP
processors, so I would probably need some help. Are there people in
this project that can help me with that kind of stuff?

Cheers,
//Anders
