Other information
There is currently no way to detect whether WebAudio playback has glitches (gaps in the played audio, which typically happens due to underperformance in the audio pipeline). There is an existing way to measure the instantaneous playback latency using AudioContext.outputLatency, but no simple way to measure average/minimum/maximum latency over time. With this API, we want to propose a way to be able to measure the delay of that audio and the playback quality of the audio.
