| Passed parameter | Return type | Description |
|---|---|---|
| "balance" | integer | Balance value in the range of -100 (100% left channel) to 100 (100% right channel). A value of 0 means 50% balance or balance could not be retrieved. |
| "duration" | integer | Total length of sound in milliseconds, or -1 if the duration could not be retrieved. |
| "loop" | boolean | True if the sound is looped, false if it is only played once or if the property could not be retrieved. |
| "offset" | integer | Current playtime of the sound in milliseconds, or -1 if the offset could not be retrieved. |
| "paused" | boolean | True if the sound is currently paused, false if it is playing or not active at all. |
| "playing" | boolean | True if the sound is currently playing, false otherwise. |
| "volume" | integer | Level of volume in the range of 0 (mute) to 100 (full volume). A value of -1 is returned, if the volume could not be retrieved. |
Examples
Example 1: Store the current playtime of an active sound in a variable.
-- Sound id can only be retrieved if the sound is active
local mySoundId = getSoundId("vispath:sounds/example.ogg")
local soundOffset = getSoundProperty(mySoundId, "offset")
