a webapp for chopping breakbeats
check it out at https://rhythmclinic.org/junglechopper
uses the js webaudioapi to chop and reassemble the amen break. I used this article heavily as a guide for webaudioapi.
the grid is a dynamically generated html table. try changing the NUM_CHOPSvariable at the top of main.js to change the size of the grid and the length of each chop. you could also change the sample by replacing amen.mp3 and changing NUM_BARS and INPUT_BPM.
to run this locally you need to use a webserver to deal with CORS. I just used python3 -m http.server
