I would have thought that it had killed the properties of your filters ? There are two issues: - how to do convolution fast - how to go from one filter to the other The main issue with changing filters is that your system is not LTI anymore. If your filters have finite impulse answer, I guess it should not be too much of an issue. To do convolution quickly, you need to use FFT, which is a bit tricky if you want to do things in real-time, as you need to partition the impulse response. Using "partitioned impulse answer" as keywords should give you plenty of references on how to do it, David _______________________________________________ NumPy-Discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
