But what if there are no instruments being played? whats the concept then? the idea of this show is to remove the stage entirely and have a shared experience between audience and performer.
]
But the experience can never be shared-no matter how hard you try.
The performer (if actually performing) is going to produce a sound of some sort (or why is a sound system needed?).
When they produce that sound THEY experience it-no body else does (unless it has an onstage amplifier.
Then the will hear the delayed signal getting back to them.
The audience however-does not get the original sound and only the sound from the system. So they have 1 arrival while the musician (can you say that if there are no instruments?
) gets 2 sources (original nd from system. It is this delayed signal that would cause the problem with performance.
Of course if IEMs are used then it is reduced.
HOWEVER consider that if there is signal point toward the stage-then the stage mics will pickup this delayed signal and amplify it-causing even more delay and a smearing of the sound.
And before people talk about directional microphones-consider that the sound is coming from 360° around the stage-so the mic WILL be pointed towards a sound source.
Unless I am missing something is what is going on.
