Sorry, a bit OT..Another abstract (2015) that has the interesting detail about a scalar slide input for users to select the preferred amount of "multi loudspeaker eq" and "ordinary" REQ:
..However, since a full dereverberation may not always be desirable, we shall here study the proposed method from the perspective of how to control the amount of room correction for a given number of contributing support loudspeakers. The amount of correction is controlled by a scalar parameter that we interpret as a "focus control," enabling the user to slide seamlessly between a single-channel equalizer and a full multichannel inversion of the room.
