[outsig, fc] = auditoryfilterbank(insig,fs); [outsig, fc] = auditoryfilterbank(insig,fs,...);
insig | input acoustic signal. |
fs | sampling rate. |
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.
The following parameters may be passed at the end of the line of input arguments:
'flow',flow | Set the lowest frequency in the filterbank to flow. Default value is 80 Hz. |
'fhigh',fhigh | Set the highest frequency in the filterbank to fhigh. Default value is 8000 Hz. |
'basef',basef | Ensure that the frequency basef is a center frequency in the filterbank. The default value of [] means no default. |
