The envelope of each auditory filter output is processed by a modulation filterbank

Evidence

In the monaural pathway the output of the adaptation loops was analysed by a modulation filterbank, where the highest centre frequency of the modulation filters was restricted to a quarter of the centre frequency of the auditory filter. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3473
