Dear audiodsp group, I have designed a function for audio resampling between arbitrary rates using the common "windowed sinc" interpolation with FIR filter. The function works well, but please could you answer a few questions about the resampling quality for me? * Do I understand correctly that the number of filter "taps" is equal to the FIR window size in terms of input samples? i.e. in...

Dear all, I wonder whether you can help me. I recently stumbled across the paper "Improved Phase vocoder Time-scale modification of Audio", and have tried rather unsuccessfully to implement it in Matlab. Therefore, I would be ever so grateful for some hints as to where I seem to be going wrong, or even some Matlab code (if you have it, and are willing to send it to me). I belie...
