I think a solution that uses setInterval() to schedule frequent JS callbacks, checks AudioContext.currentTime to measure the progress of the audio clock, and uses AudioBufferSourceNodes to queue playback of generated audio buffers, should work as well as any other, providing the Web Audio implementation is adequate. Incremental GC might also be required.
