Oh, I wanted this years ago when phones had terrible microphones and audio codes.

The idea was that at a gig loads of people would record and you could reconstruct a much better recording.

I'd assume a lot of the losses would be the same across all devices - e.g. GSM and associated preprocessing will result in dynamic compression in a uniform way regardless of placement, no? It's an interesting idea but it seems like you'd need a mixture of different compression types.
