Disable Auto Gain Control

Disables auto gain control on an active call, so the microphone input level is sent unaltered.

Use this when the input is already at a known, controlled level — for example a professionally mixed feed — and the browser's automatic adjustment is working against you.

Signature

disableAutoGainControl(callId: string): Promise<void>

Parameters

Parameter	Type	Required	Description
callId	string	Yes	Identifier of the active call

Return Type

Returns a Promise that resolves once the constraint has been applied.

Usage Example

const callId = 'callId';
await client.disableAutoGainControl(callId);

Errors

Error Type	Error Code	Description
INTERNAL_ERROR	media:error:track_not_found	No active call or no outgoing audio track found for provided callId
UNKNOWN_ERROR	N/A	Unexpected failure

Notes

• Web only. Android and iOS do not expose auto gain control
• Currently marked experimental
• Requires an active call — call this once media is established
• Changing one audio processing constraint preserves the other two
