LSND/SSND - Loop a Sound¶
Loop a WAV file, playing until you send the equivalent SSND
.
X-Plane includes many sound files under <XP>/Resources/sounds
.
- Send
Use the relative path to the sound file (e.g.,
Resources/sounds/alert/fire_bell.wav
):path = 'Resources/sounds/alert/fire_bell.wav' msg = struct.pack('<4sxiff500s', b'LSND', index, # 0-4 freq, # frequency, 1.0 == 100% vol, # volume, 1.0 == 100% path.encode('utf-8')) # remember to encode string as bytes sock.sendto(msg, (beacon['ip'], beacon['port']))
This loops the given sound. See SOUN to play a sound once.
freq
and vol
play the sound relative to how it was recorded: 1.0 means play at
100% of original speed, and original volume.
You can enable up to 5 loops to play at the same time, by assigning different values
for index
, and sending five UDP commands.
To stop looping, send the same command with SSND
, and a matching index number.
