Calculating the SNR of Audio Signal (Recommended Libraries) Are there any open source packages or libraries available which can be useful in calculating the SNR(signal to noise ratio) of an audio signal.

The input will be just an audio signal and I have to calculate the SNR of that signal. Can anyone suggest any library in python/C/C++ or any other language which does this or can be useful?
It is really hard to create something to estimate the SNR in all cases. Each case requires its own treatment according to model of the acquisition of the signal.

For instance, if the model is AWGN noise an the audio is of human voice and data is samples in high sample rate (Let's say above 44.1 [KHz]) then you can use a lot of the bins in the DFT of the signal to estimate the Noise STD.
Then according to the energy in the bins of the data you can estimate the SNR.

Regarding a library, you might find general tools in Mozilla's Deep Speech library.
