Applies a multiplier to the audio flowing through the mix engine (FreeSWITCH channel read volume) — changes what other participants hear, not what the local browser captures. For local PC mic gain, use Call.setLocalMicrophoneGain instead. ## **Parameters** **`value`** `number` — required Volume level (0-100). --- ## **Returns** `Promise` #### Inherited from [`Participant`](/docs/browser-sdk/v4/reference/participant).[`setAudioInputVolume`](/docs/browser-sdk/v4/reference/participant#setaudioinputvolume) ## **Examples** ```ts await selfParticipant.setAudioInputVolume(value); ``` > Sets the server-side microphone volume on this participant's bridged call leg.
