Inside Macintosh: Sound

Sound Data

The Sound Manager can play sounds defined using one of three kinds of sound data:

square-wave data
wave-table data
sampled-sound data

This section provides a brief description of each of these kinds of audio data and introduces some of the concepts that are used in the remainder of this chapter. A complete description of the nature and format of audio data is beyond the scope of this book. There are, however, numerous books available that provide complete discussions of digital audio data.
