Where is the Noise Reduction/Removal source code?

Hello fellow coders.

I’m researching about Sound Source Separation. I would really like to study the algorithm behind noise reduction. Can anyone point me to where the Noise Reduction source code is?

I’m viewing the source code from here: https://code.google.com/p/audacity/source/browse/audacity-src/trunk

Try looking in https://code.google.com/p/audacity/source/browse/audacity-src/trunk#trunk%2Fsrc%2Feffects for NoiseRemoval.cpp and NoiseRemoval.h .


It it harder to understand than I thought. But Thanks!
