Stereo Channel Selection
The selection or weighting of one stereo channel for downstream speech processing based on activity, quality, speaker separation, or channel-specific signal conditions.
Speech Processing Context
Stereo channel selection chooses the channel that currently provides more useful speech evidence, using measures such as VAD confidence, energy, SNR, or speaker activity. Hysteresis can prevent rapid channel switching when the evidence is close.
Modeling Boundary
Channel selection is not source separation. If both channels contain the same acoustic mixture, selecting one channel cannot mathematically recover independent speakers.
