Granular synthesis is a method of sound synthesis based on splitting the audio into small pieces and playing them with short intervals. After loading a sample, you can start creating grains by clicking and holding your mouse on the waveform. The X axis will determine the position and Y axis will change the amplitude of each grain. This app also has multi-touch support for up to three voices and real-time manipulation of settings. Tested on: Google Chrome,Firefox, Safari, Chrome iOS (iPad), Safari iOS (iPad) Libraries used: Web Audio AP, Processing.js, Bootstrap 3,jQuery Knob. Performance Tip: Try using a quick attack and release as well as low density when using multi-touch for better performance.
