This is an interesting idea that I think could benefit us too, but we do understand that RadioCaster is a smaller program.
We currently have 2 sites - studio and transmitter site. We use the pira.cz silence detector software and we'd like to invoke API commands so that when silence is detected, it stops RadioCaster on the studio site, and starts streaming on the transmitter site to allow our backup music to play to air. Then when audio resumes, it does the opposite - stop streaming on the transmitter site instance, and starts it on the studio end.
Currently it's a manual process where we stop streaming and start it manually. The only other idea I've had is getting a CMD script to force close the app, and open the other... but that screams danger...
We would use RadioBOSS, but I'm worried about the resource usage, as they're only small NUCs and running a full instance may be less reliable than the Caster software.
