|index||The index of the sound to check.|
This function will return the length of the given sound in
seconds. The sound can either be a referenced from index for an
individual sound being played which has been stored in a variable
when using the audio_play_sound or audio_play_sound_at
functions, or an actual sound asset from the resource tree.
len = audio_sound_length(snd_Beam);
audio_play_sound(snd_Beam, 1, false);
alarm = room_speed * len;
The above code gets the length (in seconds) of the sound indexed in the variable "snd_Beam", then plays the sound and sets an alarm to go off when the sound has finished playing using the length of the sound to calculate the time needed for the alarm.
