Inter-channel coherence ICC measures signal similarity normalized from 0 to 1

Evidence

This indicates that the present approach was too simplistic, i.e., modulation cues may only be reduced and not abolished by the presence of the interferer. In addition, not only modulation frequencies close to the beating frequency may be affected by the presence of the interferer but also other modulation frequencies. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3494 (#contradicts, via linked claim)
