signal processing - Python Audio Analysis: What properties/values can I extract from it?

Question

I'm currently working on a tkinter python school project where the sole purpose is to generate images from audio files, I'm going to pick audio properties and use them as values to generate unique abstract images from it, however I don't know which properties I can analyze to extract the values from. So I was looking for some guidance on which properties (audio frequency, amplitude... etc.) I can extract values from to use to generate the images with Python.

Answer 1

Time domain: Zero-crossing rate, Root mean square energy ,etc . Frequency Domain: Spectral bandwith,flux,rollof,flatness,MFCC etc. Also ,tempo, You can use librosa for Python , link : https://librosa.org/doc/latest/index.html for extraction from a .wav file , which implements Fast Fourier Transfrom and framing. And then you can apply some statistics such mean,standard deviation to the vector of the above characteristics across the whole audio file.
