Audio

Description

Supported Script Types: Interface Scripts • Client Entity Scripts • Avatar Scripts • Server Entity Scripts • Assignment Client Scripts

The Audio API provides facilities to interact with audio inputs and outputs and to play sounds.

Properties

Name Type Summary
muted boolean

true if the audio input is muted for the current user context (desktop or HMD), otherwise false.

mutedDesktop boolean

true if desktop audio input is muted, otherwise false.

mutedHMD boolean

true if the HMD input is muted, otherwise false.

warnWhenMuted boolean

true if the "muted" warning is enabled, otherwise false. When enabled, if you speak while your microphone is muted, "muted" is displayed on the screen as a warning.

noiseReduction boolean

true if noise reduction is enabled, otherwise false. When enabled, the input audio signal is blocked (fully attenuated) when it falls below an adaptive threshold set just above the noise floor.

noiseReductionAutomatic boolean

true if audio input noise reduction automatic mode is enabled, false if in manual mode. Manual mode allows you to use Audio.noiseReductionThreshold to set a manual sensitivity for the noise gate.

noiseReductionThreshold number

Sets the noise gate threshold before your mic audio is transmitted. (Applies only if Audio.noiseReductionAutomatic is false.)

inputVolume number

Adjusts the volume of the input audio, range 0.01.0. If set to a value, the resulting value depends on the input device: for example, the volume can't be changed on some devices, and others might only support values of 0.0 and 1.0.

inputLevel number

The loudness of the audio input, range 0.0 (no sound) – 1.0 (the onset of clipping). Read-only.

clipping boolean

true if the audio input is clipping, otherwise false.

context string

The current context of the audio: either "Desktop" or "HMD". Read-only.

devices object

Read-only.

Deprecated: This property is deprecated and will be removed.

pushToTalk boolean

true if push-to-talk is enabled for the current user context (desktop or HMD), otherwise false.

pushToTalkDesktop boolean

true if desktop push-to-talk is enabled, otherwise false.

pushToTalkHMD boolean

true if HMD push-to-talk is enabled, otherwise false.

pushingToTalk boolean

true if the user is currently pushing-to-talk, otherwise false.

avatarGain number

The gain (relative volume in dB) that avatars' voices are played at. This gain is used at the server.

localInjectorGain number

The gain (relative volume in dB) that local injectors (local environment sounds) are played at.

pushingToTalkOutputGainDesktop number

The gain (relative volume in dB) that all sounds are played at when the user is holding the push-to-talk key in desktop mode.

acousticEchoCancellation boolean

true if acoustic echo cancellation is enabled, otherwise false. When enabled, sound from the audio output is suppressed when it echos back to the input audio signal.

isStereoInput boolean

true if the input audio is being used in stereo, otherwise false. Some devices do not support stereo, in which case the value is always false.

isSoloing boolean

true if currently audio soloing, i.e., playing audio from only specific avatars. Read-only.

soloList Array.<Uuid>

The list of currently soloed avatar IDs. Empty list if not currently audio soloing. Read-only.
