Sequencing Audio Using React and the Web Audio API
summary
A faithful web recreation claims to synthesize the TR-808 drum sounds synthesized without samples using React, Redux and the Web Audio API and ships as IO808 released for 8/8; timing relies on the audio context with a hybrid scheduling approach (references an NPM scheduler) rather than naive setInterval. State scales to 12,288 steps in the Redux store. Also includes GPU fragment-shader visuals via WebGL; the demo runs and sounds close to the original with no heavy bespoke optimization.
