ABSTRACT
Source coding for audio and speech signals is introduced in Chapter 3. Coding techniques such as linear predictive coding, code excited linear predictive coding, and sub-band coding are presented. Transform coding techniques such as Fourier transform, wavelet transform, discrete wavelet, and discrete wavelet packet transforms have also been discussed. An in-depth discussion on psychoacoustic model employing daubchies wavelet for speech coder is also presented.
