CHAPTER 17Digital Signal Processing

In many ways, digital signal processing (DSP) returns us to the elemental beginning of our discussion of digital audio. Although conversion, error correction, data reduction, and other concerns can be critical to a digitization system, it is the software-driven signal processing of digital audio data that is germane to the venture. Without the ability to manipulate the numbers that comprise digital audio data, its digitization would not be useful for many applications. Moreover, a discussion of digital signal processing returns us to the roots of digital audio in that the technology is based on the same elemental mathematics that first occupied us. On the other hand, digital signal processing is a science ...
