Analysis Summary: This experiment limits sample rate and channel count in voice calls when noise or echo processing is enabled.
Why It Matters: It may improve processing stability or compatibility, but it can also affect clarity and stereo presentation.
Measured results are needed to determine the actual user impact.
Detailed Description: This experiment adjusts voice-quality ceilings when noise or echo processing is active in a call.
The default adds no sample-rate or channel-count cap.
Treatments cap the sample rate at 32 kHz when Krisp, standard noise suppression, echo cancellation, or any of those modes is active; some treatments also cap audio to one channel.
The client applies these values to the active voice engine whenever voice-processing settings are refreshed.
There is no separate user-facing toggle, and the code does not establish the measured tradeoff between stability and audible quality.
