[sdiy] resampling wav files

Hi,

Looks like there's some DSP in my future. I need to resample wave files 
to get them from 600 samples down to 256 samples. Unless there is a 
groovy toll out there that can do that, I gotta write an app for it. As 
far as I can tell I need to interpolate 32x and then decimate 75x, with 
all the attendant filters that these processes need. I know just enough 
DSP to be dangerous.

Thoughts?
