|index||The index of the sound to check.|
When adding audio to GameMaker: Studio it can be either
streamed or in memory. If you need to know whether a
given sound index is for streamed audio or not you can use this
function which will return 1 for streamed, 0 for sound in memory,
and -1 if there is any error or the index does not point to a valid
type = audio_get_type(snd_Music_1);
The above code checks the type of audio indexed in the variable "snd_Music_1" and stores the returned value in the variable "type".
