    Hi!!

    I have an mp3 file with multiple sound effects, separated by ~300 milliseconds of silence.

    How would you guys suggest a way of obtaining the timecodes (in milliseconds) of each sound effect?

    I wanna end-up with something like this (key names by user input):
    Code:
    'JSON
    {
        
    "Whoosh": {
            
    "Start""830",
            
    "Stop""2121"
        
    },
        "Boom": {
            "Start": "2256",
            "Stop": "4765"
        },
        ...
    }

    Maybe by using the fft lib? it is used to create sound wave (equalizer) représentations… then its a mater of "detecting" the silence...

    My Python library is very limited in terms of supporting other libraries, I'm also missing the 64bit binary... :/
