LTFAT - Filterbanks

Peter L. Søndergaard, 2011 - 2023.

Transforms and basic routines

filterbank - Filter bank
ufilterbank - Uniform Filter bank
ifilterbank - Inverse normal/uniform filter bank
ifilterbankiter - Iteratively inverse filter bank
filterbankwin - Evaluate filter bank window
filterbanklength - Length of filter bank to expand signal
filterbanklengthcoef - Length of filter bank to expand coefficients

Filter generators

cqtfilters - Logarithmically spaced filters
erbfilters - ERB-spaced filters
warpedfilters - Frequency-warped filters
audfilters - Filters based on auditory scales
gabfilters - Linearly spaced Gabor filters
waveletfilters - Waveletfilters

Window construction and bounds

filterbankdual - Canonical dual filters
filterbanktight - Canonical tight filters
filterbankrealdual - Canonical dual filters for real-valued signals
filterbankrealtight - Canonical tight filters for real-valued signals
filterbankbounds - Frame bounds of filter bank
filterbankrealbounds - Frame bounds of filter bank for real-valued signals
filterbankresponse - Total frequency response (a frame property)

Auxilary

filterbankfreqz - Frequency responses of filters
filterbankscale - Scaling and normalization of filters
nonu2ufilterbank - Non-uni. to uniform filter bank transformation
u2nonucfmt - Change format of coefficients
nonu2ucfmt - Change format of coefficients back

Plots

plotfilterbank - Plot normal/uniform filter bank coefficients

Reassignment and phase gradient

filterbankphasegrad - Instantaneous time/frequency from signal
filterbankreassign - Reassign filterbank spectrogram
filterbanksynchrosqueeze - Synchrosqueeze filterbank spectrogram

Phase reconstruction

filterbankconstphase - Construct suitable phase from the coefficient magnitude
