Click Removal & Noise suppression
by Nicolas Montgermont 01 Mar '17

01 Mar '17

Hello list, I'd like to implement click removal and noise suppression techniques for a specific signal I have that is full of: - loud clicks, but very regular in time and short (2ms) - 50 Hz noise with harmonics. This one has two spectral patterns switching to one or the other during time. For the clicks, I tried median filtering, but it's not working well. I tried to work with audacity on a recorded extract, and I have pretty good results with their click suppression and noise removal algorithms. So I was thinking of implementing them in Pd, but before I do that I was wondering if some of you have already implemented some of these techniques, or of you have any advices? https://github.com/audacity/audacity/blob/master/src/effects/ClickRemoval.c… https://github.com/audacity/audacity/blob/master/src/effects/NoiseRemoval.c… Best, Nicolas
