useful application of oversampled subband audio processing can be described as frequency domain based gain adjustment. In this appli-cation, an oversampled filter bank is used to separate the broadband audio signal into a number of well separated subbands such that they can be adjusted independently [1]. In the simplest case, the ampli-

The STFT also computes a uniform filter bank, but it can be used as the basis for a variety of non-uniform filter banks, as discussed in §10.7, to give frequency resolution more like that of hearing (§7.3). For each selected STFT example below, a list of filter-bank properties is listed, followed by some discussion.

Non-uniform filter banks (NUFBs) attract particular attention in signal processing applications due to their flexibility in frequency partitioning . For example, in the design of the filter banks that approximate the time–frequency resolution of human ears, this non-uniform frequency spacing that matches the critical bands is much more preferred.

In , a method is proposed for the design of non-symmetrical (i.e. increased analysis bandwidth) oversampled filter banks with low processing delays, based on non-linear phase M-band prototype filters optimized via a constrained eigenfilter approach. Low delay is generally achieved at the cost of increasing the length of the prototype filter; the issue of …

Multirate Filter Banks The preceding chapters have been concerned essentially with the short-time Fourier transform and all that goes with it. After developing the overlap-add point of view in Chapter 8, we developed the alternative (dual) filter-bank point of view in Chapter 9.This chapter is concerned more broadly with filter banks, whether they are implemented using an FFT or by …
