Abstract
Waveform audio is one of the essential components of a multimedia system. Waveform audio can do anything within the practical limitations of memory, disk capacity, and sound card capabilities. The normal functions that one performs on tape recorder can also be done with waveform audio. One can read and write, store and retrieve, and manipulate the waveform audio. The voltage level determines the amplitude of the wave. The wave file not only contains the digital data required to produce sound, but also additional information such as the sampling rate, the type of audio data, and other critical data. Wave data comes in several formats, sampling rates, channels, and resolutions. The information appears in a format block called the Resource Interchange File Format or the RIFF chunk. The chapter also discusses the structure of the wave audio file and provides the steps for accessing the wave data and files.
