The mirror trick will help you to remove the first reflection
of the side walls for mid and high frequencies. If that will
improve the sound remains to be seen. What is very clear is
that it won't do much to improve a bad room sound because
that is not the result of just those first reflections.
Remember the last time you were standing close to a wall ?
Did that wall create a 'mirror image' of sounds arriving
from the other side ? I'm pretty sure it didn't, one reason
being that your brain will reject such images - even if you
wanted to 'see' them you wouldn't be able to. Not until the
delays get a lot larger than what a typical room will produce,
and them we're talking about discrete echos.
There are no 'rules of thumb' except some based on reliable
measurements of acoustic parameters.
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
