In python, I'm trying to create a software that finds all the frequencies of a .WAV file given a sample time. For example, if the sample time is 1 second, I want to find the frequency of the WAV file every second, then add that value to a list/dictionary in chronological order. Any way to do this (python)?
I want to be able to associate these frequencies with notes later, and the NumPy solution being linked seems to be giving me the wrong frequencies for the wav file.
