SmartAudio

SmartAudio objects are SmartObjects that wrap sound files. Similar to Audio objects, they have many of the same properties and functions.

Properties

Property Name	Return Type	Description	Tags
`isPlaying`	`boolean`	Returns if the sound is currently playing.	Read-Only
`isSpatializationEnabled`	`boolean`	Default true. Set to false to play sound without 3D positioning.	Read-Write
`isAttenuationEnabled`	`boolean`	Default true, meaning sounds will fade with distance.	Read-Write
`isOcclusionEnabled`	`boolean`	Default true. Changes attenuation if there is geometry between the player and the audio source.	Read-Write
`isAutoPlayEnabled`	`boolean`	Default false. If set to true when placed in the editor (or included in a template), the sound will be automatically played when loaded.	Read-Only
`isTransient`	`boolean`	Default false. If set to true, the sound will automatically destroy itself after it finishes playing.	Read-Write
`isAutoRepeatEnabled`	`boolean`	Loops when playback has finished. Some sounds are designed to automatically loop, this flag will force others that don't. Useful for looping music.	Read-Write
`pitch`	`number`	Default 1. Multiplies the playback pitch of a sound. Note that some sounds have clamped pitch ranges (0.2 to 1).	Read-Write
`volume`	`number`	Default 1. Multiplies the playback volume of a sound. Note that values above 1 can distort sound, so if you're trying to balance sounds, experiment to see if scaling down works better than scaling up.	Read-Write
`radius`	`number`	Default 0. If non-zero, will override default 3D spatial parameters of the sound. Radius is the distance away from the sound position that will be played at 100% volume.	Read-Write
`falloff`	`number`	Default 0. If non-zero, will override default 3D spatial parameters of the sound. Falloff is the distance outside the radius over which the sound volume will gradually fall to zero.	Read-Write
`fadeInTime`	`number`	Sets the fade in time for the audio. When the audio is played, it will start at zero volume, and fade in over this many seconds.	Read-Write
`fadeOutTime`	`number`	Sets the fadeout time of the audio. When the audio is stopped, it will keep playing for this many seconds, as it fades out.	Read-Write
`startTime`	`number`	The start time of the audio track. Default is 0. Setting this to anything else means that the audio will skip ahead that many seconds when played.	Read-Write
`stopTime`	`number`	The stop time of the audio track. Default is 0. A positive value means that the audio will stop that many seconds from the start of the track, including any fade out time.	Read-Write

Functions

Function Name	Return Type	Description	Tags
`Play()`	`None`	Begins sound playback.	None
`Stop()`	`None`	Stops sound playback.	None
`FadeIn(number time)`	`None`	Starts playing and fades in the sound over the given time.	None
`FadeOut(number time)`	`None`	Fades the sound out and stops over time seconds.	None
