I would be grateful if you could help me in the following issue:
I have a "Pure Speech" audio file and a "Noisy" audio file which consists of "Pure Speech" and background noise (passed through a microphone).
I need to extract the background noise (Not Speech) from the "Noisy" file using the "Pure Speech" as the reference signal.
I tried different kinds of LMS and RLS algorithm to do that, but all of these algorithms failed to extract the background noise.
It would be very helpful if you could guide me what the problem is.
