Given in my case I am not concerned with mangling the audio (it is

mics), I have no reservations towards resorting to destructive kinds

TDOA between multiple mics.
But earlier:
Does anyone have access to an easy to implement (as in code)
dereverberation algorithm assuming one has access to the room impulse
response? I am looking for a way to clean-up recorded audio signal in
order to improve signal clarity (e.g. speech).
So now I'm a bit confused... Do you need improved audio, or just
signal statistics ???
Good point. As long as the spectral content is more accurate because it
is devoid of extraneous reflections and therefore potentially altering
the spectral composition to the point it fails to be cross-correlated
correctly, and a single window of sound is enough to do a more accurate
cross-correlation, I am fine with that. The in-between-windowing
artifacts do not concern me as long as they are not a cause of signal
degradation to the point where cross-correlation is affected by it. Hope
this helps. Thank you all for your input so far.
Best,
Ico
