Perceptual Metrics for Ideal Reverberation
Some desirable controls for an artificial reverberator
include
• t60(f) = desired reverberation time at each frequency
• G 2 (f) = signal power gain at each frequency
• C(f) = “clarity” = ratio of impulse-response energy
in early reflections to that in the late reverb
• ρ(f) = inter-aural correlation coefficient at left and
right ears
Perceptual studies indicate that reverberation time t60(f)
should be independently adjustable in at least three
frequency bands.
