Parsing Sound Resources and Sound Files

This section explains how you can parse sound resources and sound files to find the component of a sound resource or sound file that contains information about the sound. For sound resources, this information is stored in the sound header. In addition to obtaining information about a sound from a sound header, you might need a pointer to a sound header to use any of several low-level sound commands. For sound files, information is stored in the Form and Common Chunks. This section shows how you can find those chunks and extract information from them.

The techniques shown in this section assume that you are familiar with the format of sound resources and sound files. See "Sound Storage Formats" for complete information on sound storage formats.
