Convolution and Deconvolution in Python using scipy.signal

Question

I am trying to do some (de)convolution with audio samples. I have one sample s and the same sample with some filters added on top of it s_f

Answer 1

The rank(x) returns the rank of matrix. In other words number of dimensions it contains. Please check whether ranks of s and f are the same before call to signal.convolve(). Otherwise you will receive an exception you quote.

I have no idea why deconvolution may return something with more dimensions than given input. This requires deeper investigation I don't have time for.
