baumgartner2014_gradientextraction - - Extraction of positive spectral gradients
Usage
[gp,gfc] = baumgartner2014_gradientextraction(mp,fc)
Input parameters
| mp | spectral magnitude profile in dB |
| fc | center frequencies |
Output parameters
| gp | positive spectral gradient profile |
| gfc | center frequencies of gradient profile |
- baumgartner2014_gradientextraction(...) is a spectral cue extractor
- inspired by functionality of dorsal cochlear nucleus in cats.
baumgartner2014_gradientextraction accepts the following optional parameters:
| 'c2',c2 | Inhibitory coupling between type II mpd type IV neurons. Default is 1. |
| 'c4',c4 | Inhibitory coupling between AN and type IV neuron. Default is 1. |
| 'spacing',sp | Tonotopical spacing between type IV mpd II neurons in ERBs. Default is 1 ERB. |
baumgartner2014_gradientextraction accepts the following flags:
| 'positive' | Perform positive spectral gradient extraction (default). |
| 'negative' | Perform negative spectral gradient extraction. |
| 'both' | Perform spectral gradient extraction. |
