So? You can tune in with any major player, and these services probably do the very same for their silence detection.
Just use the direct streaming URL you find in the control panel at spacial.com
Most of the ones I have come across need you to also input the server, server type, and port as well as the url that the stream is playing on. mediaMon will set up their program for you to do that, but don't have it built in as an option.
All others I have tried do not accept just the play stream url.
