+ <summary>
+ Number of simultaneous inputs coming to the AudioRendererMixer rendering
+ audio with the latency of the exact value specified by the user. The value
+ is lifetime maximum logged on the mixer destruction. It is useful for
+ evaluating how mixing audio in renderer reduces the number of output audio
+ streams going from the renderer to the browser.

+ Subset of audio output latencies encountered during the renderer lifetime.
+ Logged on the renderer destruction. The values are bitsets where each bit
