Play raw audio sample stream using Web Audio API.

• [x] Arbitrary channel count
• [x] Arbitrary sample rate
• [x] Basic OLA (overlap-add) resampler
• [ ] Adjustable buffer size

Depends on the sample format, there are multiple player classes:

• Int16PcmPlayer (little endian)
• Float32PcmPlayer
• Float32PlanerPcmPlayer

No Planer: audio samples are interleaved (left channel first).

With Planer: audio samples are in a two-dimensional array (left channel first).

The constructors require user activation (must be invoked in a user event handler, e.g. onclick), because they create AudioContexts.

var player = Int16PcmPlayer(44100);
player.start();
player.feed(new Int16Array([0, 0, 0, 0, 0, 0, 0, 0]));
player.stop(); // `AudioContext` will be closed, so can't be restarted
