_SNDPLAYFILE

The _SNDPLAYFILE statement is used to play a sound file without generating a handle, automatically closing it after playback finishes.

Syntax

_SNDPLAYFILE filename$[, ignored%][, volume!]

Supported file formats are WAV, FLAC, OGG, MP3, MID, IT, XM, S3M, MOD or RAD (v2 only). See _SNDOPEN.
ignored% is an optional parameter , accepted for historical reasons.
- In versions prior to build 20170811/60, ignored% identified if a sound was to be loaded with "SYNC" capabilities, (-1 for true, 0 for false). This is true for all sound files in the latest versions, making this parameter safe to be ignored.
volume! is a SINGLE value from 0 (silence) to 1 (full volume). If not used or outside this range, the sound will be played at full volume.
_SNDPLAYFILE never creates an error. If the sound cannot be played it takes no further action.
The sound is closed automatically after it finishes playing.
When a sound will be used often, open the file with _SNDOPEN and use _SNDPLAYCOPY to play the handle instead to reduce the burden on the computer.

Example: Playing a sound file at half volume.
