Hi there,

    I've just developed a small package to wrap Source Rabbit Code from 
Erik de Castro de Lopo, which is a library to do high quality samplerate 
conversion (http://www.mega-nerd.com/SRC/). You can download it here:

    Example of error conversions:

    Basically, you just import resample from pysamplerate, and 
resample(sins, fr/fs) gives you a converted signal at sampling rate fr, 
with fs the original sampling rate. You can also select the conversion 
method (eg 'sinc_best', etc...). The pydocs + examples should be enough
   
    This package can be useful for people who deal with music signal 
processing and co, when scipy.resample is not enough. Only float32 and 
float64 input are supported for now, I will polish the package when I 
will have some more time,

    cheers,

    David
