Critically sampled PR filterbanks of nonuniform resolution based on block recursive FAMlet transform

Unto K. Laine

A new block recursive algorithm is introduced for effective FAMlet transform implementation. When the Fourier transform is combined with the algorithm a nonuniform resolution filterbank is created. The algorithm allows to approximate frequency resolutions of any type, the ERB-rate scale included. The signals can be vector based critically down sampled which allows a perfect reconstruction.
