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.
