The Audio File Library provides a uniform programming interface to standard digital audio file formats, including AIFF/AIFF-C, WAVE, and NeXT/Sun .snd/.au. Key goals of the Audio File Library are file format transparency and data format transparency.
The same calls for opening a file, accessing and manipulating audio metadata (e.g., sample rate, sample format, textual information, MIDI parameters), and reading/writing sample data will work with any supported audio file format. Likewise, the format of the audio data presented to the application need not be tied to the format of the data contained in the file.
