i have a little project in mind but not sure how id do it.
basically what im trying to do.... capture a certain sound (db level?) on the computer monitor and log it.
lets say i watch a video on youtube of a drummer doing a simple beat. i press play on the video, and press 'play' (or whatever it would be called) on my program and it would detect a certain sound - lets say i set the db level to pick up when the drummer hit the symbol. so lets say the video is 60 seconds long, i would have a log that the drummer hit the symbol on the 6th second, then the 15th second, then the 18th second etc.
i dont know if this would be better as a program for the computer (pc or mac) or if it could be HTML5 and all done online... open to any advise please!

Simple option: You would need to transform the audio file into an array buffer, and run that through a low pass filter. Afterwards, Downsample the output and normalise it. This should give you something that can be used to perform a count.
Complex option: same as above, but prior to the previous options first step, isolate each individual track using a histogram analysis, allowing you to better focus on individual aspects.
