AudioSource Inherits from Behaviour

A representation of audio sources in 3D.

An AudioSource is attached to a GameObject for playing back sounds in a 3D environment. In order to play 3D sounds you also need to have a AudioListener. The audio listener is normally attached to the camera you want to use. Whether sounds are played in 3D or 2D is determined by AudioImporter settings.

You can play a single audio clip using Play, Pause and Stop. You can also adjust its volume while playing using the volume property, or seek using time. Multiple sounds can be played on one AudioSource using PlayOneShot. You can play a clip at a static position in 3D space using PlayClipAtPoint.

Variables
volume

The volume of the audio source (0.0 to 1.0)

pitch

The pitch of the audio source.

time

Playback position in seconds.

timeSamples

Playback position in PCM samples.

clip

The default AudioClip to play

isPlaying

Is the clip playing right now (Read Only)?

loop

Is the audio clip looping?

ignoreListenerVolume

This makes the audio source not take into account the volume of the audio listener.

playOnAwake

If set to true, the audio source will automatically start playing on awake

velocityUpdateMode

Whether the Audio Source should be updated in the fixed or dynamic update.

panLevel

Sets how much the 3d engine has an effect on the channel.

bypassEffects

Bypass effects (Applied from filter components or global listener filters)

dopplerLevel

Sets the Doppler scale for this AudioSource

spread

Sets the spread angle a 3d stereo or multichannel sound in speaker space.

priority

Sets the priority of the AudioSource

mute

Un- / Mutes the AudioSource. Mute sets the volume=0, Un-Mute restore the original volume.

minDistance

Within the Min distance the AudioSource will cease to grow louder in volume.

maxDistance

(Logarithmic rolloff) MaxDistance is the distance a sound stops attenuating at.

pan

Sets a channels pan position linearly. Only works for 2D clips.

rolloffMode

Sets/Gets how the AudioSource attenuates over distance

Functions
Play

Plays the clip with a certain delay

Stop

Stops playing the clip.

Pause

Pauses playing the clip.

PlayOneShot

Plays an AudioClip, and scales the AudioSource volume by volumeScale.

GetOutputData

Returns a block of the currently playing source's output data

GetSpectrumData

Returns a block of the currently playing source's spectrum data

Class Functions
PlayClipAtPoint

Plays the clip at position. Automatically cleans up the audio source after it has finished playing.
