shepard-tone's Issues

Make the class more like OscillatorNode

Currently the ShepardTone class has a custom interface with timeouts that conflict with the scheduling mechanisms of the Web Audio API.
While a separate high level interface with play and pause methods may be desirable, there needs to be a basic class whose behavior matches that of the native OscillatorNode as close as possible.

I have a proof-of-concept implementation that mimics an oscillator interface with the caveat that you can only change the frequency in discrete steps. I can clean it up if you're open to adding it to your package.
