If not, please ask me some more questionsSome news about our project with ClemChen.Okay, I indeed did that. The problem is, as I thought, that this gives the audio volume, but what I need is the audio level, as in the visualization modules. For this, I think I need to access the audio buffers...

Audio Bar Graph Video sub filter
--AudioBarGraph_V-i_values=<Chaîne>
Value of the audio channels levels
Value of the audio level of each channels between 0 and 1Each level
should be separated with ':'.
--AudioBarGraph_V-x=<Entier>
Position X
Position X du logo. Vous pouvez le déplacer en faisant un clic droit
dessus.
--AudioBarGraph_V-y=<Entier>
Position Y
Position Y du logo. Vous pouvez le déplacer en faisant un clic droit
dessus.
--AudioBarGraph_V-transparency=<Entier [0 .. 255]>
Transparence du logo
Transparence du logo (255 = opaque, 0 = transparent).
--AudioBarGraph_V-position={0 (Centré), 1 (Gauche), 2 (Droite), 4 (Haut), 8 (Bas), 5 (Haut-Gauche), 6 (Haut-Droite), 9 (Bas-Gauche), 10 (Bas-Droite)}
Position du logo
Forcer l’alignement du logo dans sa fenêtre. Par défaut (0) :
elle sera centrée (0=centré, 1=gauche, 2=droite, 4=haut, 8=bas,
vous pouvez également spécifier une combinaison des ces valeurs,
par exemple 6 = haut-droit).
--AudioBarGraph_V-alarm=<Entier>
Alarm
Signals a silence and displays and alert (0=no alarm, 1=alarm).
--AudioBarGraph_V-barWidth=<Entier>
Bar width in pixel (default : 10)
Width in pixel of each bar in the BarGraph to be displayed (default :
10).
Audio part of the BarGraph function
--AudioBarGraph_A-address=<Chaîne>
TCP address to use (default localhost)
TCP address to use to communicate with the video part of the Bar
Graph (default localhost).In the case of bargraph incrustation, use
localhost.
--AudioBarGraph_A-port=<Entier>
TCP port to use (default 12345)
TCP port to use to communicate with the video part of the Bar Graph
(default 12345).Use the same port as the one used in the rc interface.
--AudioBarGraph_A-barGraph=<Entier>
Defines if BarGraph information should be
send (default 1)
Defines if BarGraph information should be send. 1 if the information
should be sent, 0 otherwise (default 1).
--AudioBarGraph_A-barGraphRepetition=<Entier>
Sends the barGraph information every n audio
packets (default 4)
Defines how often the barGraph information should be sent. Sends the
barGraph information every n audio packets (default 4).
--AudioBarGraph_A-silence=<Entier>
Defines if silence alarm information should
be send (default 1)
Defines if silence alarm information should be send. 1 if the
information should be sent, 0 otherwise (default 1).
--AudioBarGraph_A-timeWindow=<Entier>
Time window to use in ms (default 5000)
Time Window during when the audio level is measured in ms for silence
detection. If the audio level is under the threshold during this
time, an alarm is sent (default 5000).
--AudioBarGraph_A-alarmThreshold=<Flottant>
Minimum Audio level to raise the alarm
(default 0.1)
Threshold to be attained to raise an alarm. If the audio level is
under the threshold during this time, an alarm is sent (default 0.1).
--AudioBarGraph_A-repetitionTime=<Entier>
Time between two alamr messages in ms
(default 2000)
Time between two alarm messages in ms. This value is used to avoid
alarm saturation (default 2000).
