baumgartner2016_gradientextraction - - Extraction of positive spectral gradients
Usage
[gp,gfc] = baumgartner2016_gradientextraction(mp,fc)
Input parameters
| mp | discharge rate profile |
| fc | center frequencies |
Output parameters
| gp | positive spectral gradient profile. Fields: gp.m for magnitude and gp.sd for standard deviation. Dimensions (4-6 optional): 1) frequency, 2) position (polar angle), 3) channel (L/R), 4) fiber type, 5) time frame. |
| gfc | center frequencies of gradient profile |
- baumgartner2016_gradientextraction(...) is a spectral cue extractor
- inspired by functionality of dorsal cochlear nucleus in cats.
