Auditory chimeras swap spectral envelopes between signals to isolate cue contributions

Evidence

As described in Wang et al. ( 2011 ), the chimeric tokens were generated in a condition with 16 channels. These 16 FIR band-pass filters with nearly rectangular response were equally spaced on a cochlear frequency map, ranging from 80 to 8820 Hz. In order to avoid the blurriness between E and FS in the chimeric stimuli, we adopted a lowpass filter (cut-off at 64 Hz) for extraction of the envelopes from the filters. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3380
