Input parameters:
| insig | input acoustic signal. |
| fs | sampling rate. |
Description:
auditoryfilterbank(insig,fs) applies an auditory filterbank to the imput signal insig sampled with a frequency of fs Hz. The filterbank is composed of gammatone filters with 1 ERB wide filters.
[outsig,fc]=auditoryfilterbank(...) additionally returns the center frequencies of the filter bank.
