When I originally suggested this could be blind tested I thought that using the mute button and transfer zone would all that was required to properly blind the subject. But having played with it today I see the audio goes back about a second on transfer, so mute and pause would be required, with a suitable pause on some switches. This is all getting a bit complicated for a human to do reliably, software could be written to do it, with something like a sub 2 second silence between switches, but it would only work for this scenario so it's very limited in scope.
