I guess Julien means removing the room's contribution from a
recording made in that room. It *should* be possible, using
similar techniques as for normal room correction, provided
the source is in a fixed position.

Suppose you set up a microphone to record a solo voice.
Put a speaker at the place where the singer is going to
be, measure the IR, and invert. This still requires a
flat reference mic to remove the contribution from the
speaker.
