Many years ago I was trying to build a "shot counter" to measure balls fired per second for a college paintball league. I ended up using sox + some Perl to be able to: - filter out only the frequency of the gun cycling - identify the peak amplitude to know when a shot started - use a sliding window of about 30ms to figure out when the shot ended - once the above was done, I could count how many shots per second and output it I even posted the code which you can see here: https://www.pbnation.com/showthread.php?t=3216349&highlight=linux https://www.pbnation.com/showthread.php?t=3216349&highlight=...
