setLocalMicrophoneGain

1
setLocalMicrophoneGain(value): void

Set the local microphone gain as a percentage applied before transmission.

• 0 = silent
• 100 = unity (no change, default)
• 200 = 2× digital boost (max; expect clipping / noise amplification)

Values are clamped to [0, 200]. Engages the local audio pipeline on first use (one-time cost).

Note: this is a digital multiplier applied in a Web Audio GainNode between your mic track and the RTCRtpSender — it does not change the physical mic’s hardware sensitivity. Browsers’ autoGainControl can fight the setting; call setAutoGainControl(false) for predictable behaviour.
