Honored ContributorThe need there I sjould use FFT instead of FIR (convolution)
Hi all! For me is very interesting can I use FFT for filtering purposes or I should only use FIR convolution? And if FFT is useful in that case, there is a boundary between it and for for ...

Honored Contributor --- Quote Start --- Thank you, Pete! And why you don't use FIR? It also have multiple c It will be very interesting if somebody will tell the way he use the core in practice. --- Quote End --- If I understood Pete: For one signal you can do one fft first then for each channel (filter) you set its stopband to zero and do ifft per channel. So still plenty of resource and delay of framing fft/ifft.
