cut the spectrogram of a wav file
Could you show some code that you have written to try out the same? It would be easier to help if we have something to build upon and rectify issues, if any.
Additionally please try basic image manipulation to do the same. Instead of cutting you could divide the image into N (here 24) regions and analyze them in parallel using multiprocessing.
I want to horizontally cut the spectrogram of a wav file into 24 pieces,and after measuring the power of each piece, and finally rank the pieces by power orders what should I do please
