Commercial room-calibration algorithms vary so widely that results are not directly comparable.

Evidence

Discussions of the effectiveness of “room equalization” or “room calibration” are confounded by the fact that commercial algorithms differ widely in the resolution of the measurements they do, the resolution of the equalization employed, and in the algorithmic rules by which the corrective filters are created, and last but not least, the target performance being strived for. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1512
