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.

Inherited Class Functions

operator bool	Does the object exist?
Instantiate	Clones the object original and returns the clone.
Destroy	Removes a gameobject, component or asset.
DestroyImmediate	Destroys the object obj immediately. It is strongly recommended to use Destroy instead.
