Further Reading

Wavelet filter banks are briefly introduced in Chapter 12. In particular, the dyadic wavelet filter bank is described--a ``constant Q'' multirate filter bank.

In addition to [264] which was frequently cited in this chapter, [267], [145], and [15] are excellent references (books). The original paper by Princen and Bradley on time-domain aliasing cancellation is [198]. The Princen-Bradley filter bank is a special case of Lapped Orthogonal Transforms (LOT) [145] for which the overlap is 50%. It is also an orthogonal perfect reconstruction filter bank with first-order FIR polyphase filters. Other papers related to perceptual audio coding include [23,262,48,146,175,16,24,17,184,15].
