Envelope and fine structure cues can be swapped across tokens to isolate their roles

Evidence

Within the healthy cochlea, broadband sounds are decomposed into narrowband signals, each of which can be considered as a relatively slowly varying envelope (ENV) imposed on a rapidly oscillating carrier (the temporal fine structure, TFS). Information about ENV and TFS is conveyed in the timing and short-term rate of nerve spikes in the auditory nerve (Joris and Yin 1992 ). Following Moore ( 2014 ), a distinction is made between the physical ENV and TFS of the input signal (ENVp and TFSp ), the ENV and TFS at a given place on the basilar membrane (ENVBM and TFSBM ), and the neural representation of ENVBM and TFSBM (ENVn and TFSn ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 794 (#expands, via linked claim)
