Perhaps the BBC could use it on SS GB? ;-)


What makes you think they have grotty mics?

Have you any idea how much decent mics cost?

A few pence!
And I really do mean they cost a few pence.


I would think they have an array of mics so that they can detect sounds
better and they would also be able to subtract the signal from the
speakers relatively easily.

Yes of course. For a stage performance you merely hide the mics inside the
speaker arrays. No need for any on the actual stage. It can all be done
with clever software.


You could use a microphone array at the edge of the stage if you could
get technicians with enough of a brain to put them in right.

Don't assume you know anything about signal processing just because you
worked in TV. It wasn't exactly needed for such a simple job.

Amazon appear to have their echo working quite well in a home
environment and the whole thing retails for £50.
