Play live audio stream - html5
Solution 1:
Use a ScriptProcessorNode, but be aware that if there is too much load on the main thread (the thread that runs your javascript, draws the screen, etc.), it will glitch.
Also, your PCM stream is probably in int16, and the Web Audio API works in terms of float32. Convert it like so:
output_float[i] = (input_int16[i] / 32767);
that is, go from a [0; 65535] range to a [-1.0; 1.0] range.
EDIT
I was using output_float[i] = (input_int16[i] / 32767 - 1);, this article shows that you should use output_float[i] = (input_int16[i] / 32767);. Now it's working fine!
