About gabor atoms / gammatone functions. [ Reply ]
By: Nicolas Vinuesa on 2012-10-24 11:47
I have a problem. In the gammatone function i have to implement the bandwidth depends of the central frequency by a ERB function (ERB=24.7 + 0.108*fc). So my function would be something like (for order 4 n=4): g(t)=a*t‎‎^(n-1)*e^(-2*pi*1.019*ERB)*cos(2*pi*fc*t + phase).
I can't see how to make the bandwidth b dependent of fc in the dictionary.
Thanks a lot!
