Hi everyone,

I am working on a problem statement where I need to extract the relevant part/section from audio files. for instance my data has audio files of engines with background noise - birds, people conversation, etc.

I read couple of papers which have mainly used PCA for denoising the noise. Couple of them have used SNR too. But I am not very convinced as how this can actually work considering that PCA take n-components value so how we can be sure that the components that it is picking up will actually not contain noise?. 

The articles/links that I explored for this are: (applies SNR), , + +  + + +n + (audio-fingerprinting),

Any lead as to how this relevant part extraction can be done would be very helpful to me.

Looking forward to getting good leads in solving this problem.
