Скачать или смотреть Music visualiser in Python

In this project, I have tried to build a music visualiser using a signal processing technique, short time Fourier transform, to analyse frequencies and amplitude of the audio signal. I have used Python libraries Pydub for basic sound analysis, sampling rate, song length, etc. and Scipy for signal analysis. I created the soundless animation in matplotlib and merged the audio (mp3 ) file and the matplotlib animation using ffmpeg-python. My current problem is that I need to manually 'time' the matplotlib soundless animation by calibrating the interval lag between frames. This is far from ideal and lead to some asynchronicity. As we say - more work is needed.

I have tried this work with a mp3 of Enya, Floras' secret.
I have no objective to violate copyrights - I only want to illustrate the application I am working on.
