Nonuniform oversampled filter banks for audio signal processing
Zoran Cvetković, James David Johnston · IEEE Transactions on Speech and Audio Processing · 2003
In emerging audio technology applications, there is a need for decompositions of audio signals into oversampled subband components with time-frequency resolution which mimics that of the cochlear filter bank and with high aliasing attenuation in each of the subbands independently, rather than aliasing cancellation properties. We present a design of nearly perfect reconstruction nonuniform oversampled filter banks which implement signal decompositions of this kind.
