Hey Mike, thanks for the response.

I am considering it, but I went the whole way and too it to a better box, better UPS, better internet connectivity, all in one so I should be good on that front. My thought is that if that nook next to our Riv box is not wired to the riv box properly for testing now,  I will look the obrx on that nook to the obtx on it in jack and send the audio right back to where it came from for latency evaluation. This leaves some latency untested but that same latency would also exist for the linphone option. If I have to I will set up an old pc and replace the pi. I have enough old pcs, I am not sure any of them are new enough though. We run RadioDJ (about 7 now with home based presenters) 3 in studio and 4 OB, all the OB's are connected via openvpn and running openob to send audio back to the studio. One crappy old box does the receiving (that worries me a bit) Also have an openob as an STL to our remote 2nd FM transmitter all of this is running on £35-£50 old sff desktop hardware and a bloody great HP Proliant DL360 G7 It just sits there and does its thing, we do get the occasional glitch but I put that down to home internet connection... Our remote presenter path looks like W10 - RadioDJ Mixer - to mix audio path Linux - openob tx Inet - to studio Linux - openob rx Kramer audio switch - allows remote switching of audio source compressor Audio splitter Is there anywhere in your chain where the home DJ is listening to the studio audio, sending vocals back to the studio where it is mixed with the audio the DJ was "talking to" and then goes out over the air. That is basically the situation I am concerned with. With some leeway if I restrict the use to remote voice tracking but it would be nice to use this setup for live remotes and even shows if the latency can get down enough. (It is early and I am tired and may not be thinking clearly right now and may be wishing for the impossible. Need to think more about it.)   * To local FM transmitter via 2 leg wifi hop over sonifex audio     streamer (would use openob but these were already there)   * To Bloody great Proliant that does silence detection, icecast,     openob tx STL and ROT What is this bit below about?

Also have jack_capture and njconnect installed on the openob nodes so that I can see what is happening IIRC, I did not know about njconnect . Are you getting it from: https://sourceforge.net/projects/njconnect/ https://github.com/radiganm/njconnect Or somewhere else? -- Mike Phillips Coast FM.n email to openob-users-leave(a)lists.talkunafraid.co.uk <mailto:openob-users-leave@lists.talkunafraid.co.uk> Thanks for the response, all the best, drew -- Enjoy the *Paradise Island Cam* playing *Bahamian Or Nuttin* - https://www.paradiseislandcam.com/ _______________________________________________ openob-users mailing list -- openob-users(a)lists.talkunafraid.co.uk To unsubscribe send an email to openob-users-leave(a)lists.talkunafraid.co.uk
