Parameters

Parameter	Type/Structure		Description
soundfile	string		Relative path to the audio file you want to play. Add the "vispath:" prefix.
flags	table	flags = 1	indicates flags table
		balance (int)	Set left/right audio balance value in the range of -100 (100% left channel) to 100 (100% right channel).
		loop (bool)	Set to true to loop the sound.
		offset (int)	Set the playtime position in milliseconds.
		volume (int)	Set the volume in the range of 0 (mute) to 100 (full volume).

Return values

Type	Description
integer	Unique id referencing the started sound, or -1 if the sound could not be started.

Examples

Example 1: Play an audio file and store the sound id for later use. Update the left/right balance of the sound while it is playing.

local mySoundId = startSound('vispath:sounds/example.ogg')
setSoundProperty(mySoundId, {flags=1, balance=40})

Example 2: Play an audio file and set balance, offset and volume.

startSound('vispath:sounds/example.ogg', {flags=1, balance=-10, offset=1000, volume=70})

+== Examples ==
-let's say you have an audio file with a duration of 00:03:24 & you want to start the audio file at: 2 minutes & 44 seconds;
-so what we need to do is convert minutes/seconds into ms like so: (2*60)*1000 + (44*1000) = 164000ms
-math explanation:
+'''Example 1:''' Play an audio file and store the sound id for later use. Update the left/right balance of the sound while it is playing.
-m*60s = 120 seconds * 1000ms = 120,000ms | 44s*1000ms = 44,000ms

-,000 + 44,000 = 164,000ms
