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.
