Hey guys,

just wondering if anyone has come across a tutorial or any information about the computeSpectrum that could help me out.

I know how to create a spectrum analyzer, however what I would like to do is be able to take the bytes from the byte array and put it back into a sound object. So for example take a song cut out, all of the high frequencies and then push those bytes back to a sound object. Does anyone know if this is possible with AS3???

Thanks
