AudioContextOptions.sampleRate

Allows developers to set the "sampleRate" for an AudioContext at the time it is created. This allows developers to set an arbitrary sample rate for audio processing in Web Audio API.

This allows developers to control the sample rate separatly from the hardware rate. Use this to reduce complexity (using a lower sample rate) or to make the sample rate consistent across devices by using a fixed rate and letting WebAudio resample appropriately for the hardware rate.
