IERBLETT ERBlet non-stationary Gabor synthesis
Usage: fr = ierblett(c,g,shift,Ls,dual)
fr = ierblett(c,g,shift,Ls)
fr = ierblett(c,g,shift)
Input parameters:
c : Transform coefficients (matrix or cell array)
g : Cell array of Fourier transforms of the analysis
windows
shift : Vector of frequency shifts
Ls : Original signal length (in samples)
dual : Synthesize with the dual frame
Output parameters:
fr : Synthesized signal (Channels are stored in the
columns)
Given the cell array c of non-stationary Gabor coefficients, and a
set of filters g and frequency shifts shift this function computes
the corresponding ERBlet synthesis.
If dual is set to 1 (default), an attempt is made to compute the
canonical dual frame for the system given by g, shift and the size
of the vectors in c. This provides perfect reconstruction in the
painless case, see the references for more information.
