DRNL filter outputs smear temporal fine structure into double impulses
Evidence
Although gammatone filters provide a good approximation of the human auditory filters, they suffer from a few shortcomings. They cannot emulate the level-dependent characteristics of the auditory filters. In addition, the impulse response of a gammatone filter has a relatively slow onset, which brings on problems when modelling phenomena involving temporally short sounds, such as the precedence effect. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1614 (
