Wayne, It is fairly easy to turn SilentJack into a "NoisyJack" type of app - changing a less then to a greater then in the source, some of the text output in the printf statements, recompile, and it'll run your command when ever noise is detected.
The trick is - you've got to build into the script that you run checks to ensure that it does not run multiple times. This can also happen with SilentJack. Otherwise as long as the condition it is looking for is true (silence or noise) it'll run the command each time the grace period is reached. > -------- Original Message -------- > Subject: [RDD] Rivendell over a remote link > From: Wayne Merricks <waynemerri...@thevoiceasia.com> > Date: Sun, February 28, 2016 7:04 pm > To: <rivendell-dev@lists.rivendellaudio.org> > > > Hi, > > I'm not sure if this is useful to anyone but heres how I made Rivendell > work over a remote VPN link seamlessly (India office broadcasting via > the UK).
