The Audacity Noise Removal Algorithm

Special Interest Groups Audio Processing

Hello.
I work on the tones generated by striking piano keys. I gather the data using Audacity but I do the processing offline using Matlab. I would like to use the Audacity noise removal algorithm via a Matlab script. Does anyone have such a script and would they be willing to share it?

Alternatively, I would like to construct a Matlab script that uses the Audacity algorithm. I see that there are several internet posts that describe the algorithm qualitatively. I have written a script derived from those comments but it clearly is not detailed enough. Can someone point me to a document that explains the algorithm in detail sufficient for a Matlab script construction?

Thanks,

Dave

As there has been no reply, I guess the answer is no.
However, the source code for the Audacity “Noise Reduction” effect is open source (GPL v2) and freely available here: https://github.com/audacity/audacity/blob/master/src/effects/NoiseReduction.cpp
If you prefer to use the old “Noise Removal” effect code: https://github.com/audacity/audacity/blob/master/src/effects/NoiseRemoval.cpp
