Returns the length of the soundfile
#include <Sound.au3>
_SoundLength ( $aSndID [, $iMode = 1] )
| $aSndID | Sound ID array as returned by _SoundOpen() or a file name |
| $iMode | [optional] This flag determines the format of the returned sound length 1 = (by default) hh:mm:ss where h = hours, m = minutes and s = seconds (default) 2 = milliseconds |
| Success: | the sound length. |
| Failure: | 0 and sets the @error flag to non-zero. |
| @error: | 1 = $iMode is invalid 3 = Invalid Sound ID. Use return array from _SoundOpen() or valid file name. |
This function will return the best available value for the length of the file regardless of encoding method or parameter type.
