Audio Parameters

Filters, adding delay, bitrate, channels, mono/stereo, muting guests etc.

They are separated in three groups: general options (push and view), source side (push) options and viewer side (view) options.

General options

You can add them to both, source (&push) and viewer (&view, &scene or &solo) sides.

Parameter	Explanation
&proaudio	Improves the audio quality, changes default audio settings and sets the audio mode to stereo
&stereo	Sets the audio mode to stereo and changes default audio settings to improve audio quality
&mutespeaker	Auto mutes the speaker
&deafen	Audio playback is muted
&noaudioprocessing	Disables all webaudio audio-processing pipelines

Source side options

You have to add them to the source side (&push).

Parameter	Explanation
&audiodevice	Pre-configures the selected audio device
&echocancellation	Automatic echo-cancellation is ON or OFF
&audiogain	Applies a gain multiplier (as a percentage) to the local microphone
&autogain	Sets whether audio auto-normalization is ON or OFF
&compressor	Applies a generic audio compressor to the local microphone
&denoise	Turn audio noise reduction filter ON or OFF
&distort	Will try to "distort" your microphone's output audio, making your voice a bit anonymous
&equalizer	Provides access to a generic audio equalizer that can be applied to the local microphone
&limiter	Applies a generic audio limiter to the local microphone
&lowcut	Adds a low-cut filter
&noisegate	Lowers your mic volume to 10% of its current value based on volume-level activity
&noisegatesettings	Lets you tweak the &noisegate variables, making it more or less aggressive as needed
&audiocontenthint	=music fixed bitrate; =speech bitrate is variable
&audiolatency	Adds an audio-latency to the published audio stream
&micdelay	Delays the microphone by specified time in ms
&mute	Starts with the microphone muted by default
&automute	Will mute the microphone of a guest when not loaded in an active OBS scene
&outboundaudiobitrate	Target audio bitrate and max bitrate for outgoing audio streams
&inputchannels	Audio capture device to select N-number of audio channels
&monomic	Sets a guest's audio input to mono (1-channel)

Viewer side options

You have to add them to the viewer side (&view, &scene or &solo).

Parameter	Explanation
&audiooutput	Like &sink, but selects the audio output device
&sink	Outputs the audio to the specified audio output device, rather than the default
&volume	Sets the 'default' playback volume for all video elements
&volumecontrol	Shows a dedicated local audio-volume control bar for canvas or image elements
&audiobitrate	Manually sets the audio bitrate in kbps
&vbr	Sets the audio bitrate to be variable, instead of constant
&mono	Has the inbound audio playback as mono audio
&noaudio	Delivers video only streams; audio playback is disabled
&nodirectoraudio*	Disables all audio playback from room directors
&panning	Pans the outgoing audio left or right, allowing for spatial audio group chats
&sync	Sets an offset (in ms) for the automatic audio sync fix node
&samplerate	Audio playback sample-rate, in hz
&channels	Specifies the number of output audio channels you wish to mix up or down to
&channeloffset	Shifts audio channels 0 and 1 up channels, based on the offset value
&playchannel	Will play either the left or right audio stream-only for an incoming stereo stream
&ptime	Audio packet size
&maxptime	Maximum packet size of audio
&minptime	Minimum packet size of audio
&audiocodec	Lets you specify the audio codec
&dtx	Turns off the audio encoder automatically when no little to no sound is detected
&nofec	Disables FEC (audio forward error correction)
