+ <summary>

+ Mismatch between the system buffer size the browser side renders audio at

+ and the buffer size it requests from renderer. When equals zero, it means

+ buffer sizes are equal. When positive, the value reflects the average number

+ of extra consecutive render requests issued by browser to renderer (scaled

+ by a factor of 1000); any positive values can cause problems for RTC. When

+ negative, it reflects the average number of extra system audio render calls

+ per one request to the renderer (scaled by a factor of 1000). Any values

+ those are not multiples of 1000 mean that from time to time browser skips a

+ call to renderer, which can cause problems for RTC.

Ilya Sherman 2016/08/24 22:20:23 How can you identify values that are not multiples
