MP3 to strobe lights algorithm

🚨 WARNING: THIS ALGORITHM PRODUCES RAPIDLY FLASHING LIGHTS. 🚨

Algorithm to generate a strobe light effect by alternating white and black fullscreen using PySimpleGUI. This is a math-heavy project.

How to use

1. place a MP3 file in the same directory as main.py
2. change the FILE_NAME variable on line 17 of main.py
3. (OPTIONAL) Other variables such as the volume can be changed at lines 16-21 in main.py
   • VOLUME variable should be kept low (try to start at 5-10)

More about the algorithm

This algorithm works like a beat detection algorithm, which uses FFT's (Fast Fourier Transform) and statistical analysis to detect spikes at certain frequencies. The SENSIBILITY_CONST variable used in the algorithm changes the sensibility to changes as the name suggests.

The sound energy of each subband is evaluated over time and compared to the average sound energy of an interval of time around the current time. A spike is detected when the current time's sound energy is higher than average.
