CD-DA

(Compact Disc-Digital Audio) The original Compact Disc format developed by Sony and Philips in the 1980s, which was designed for audio only. Since "CD" is used loosely for all Compact Disc formats, the CD-DA designation differentiates a music disc or player from its data counterparts, such as CD-ROM, CD-R and CD-RW. See Red Book audio, CDA and CD.

Back to CD-DA
Many home and car CD players only support the original CD-DA music CD format. Highly compressed music files such as MP3 and AAC that are on the computer can be converted back to CD-DA for playback in all CD players.

Although MP3 and AAC files take up about 10% of the original CD-DA file space, when "burned" back to "Audio CDs," they once again take up as much space as the original. Although the format may be CD-DA again, the quality is not. In the original CD-DA to MP3 conversion, some audio data were permanently removed.


iTunes Burning Options
iTunes lets you burn files to CD-DA ("Audio CD") or retain the MP3 file format. The "Data CD or DVD" option stores playlists on the disc. Note the message under "Data CD" that warns of potential compatibility problems if the songs are burned to data formats rather than audio (CD-DA). See iTunes and MP3.

The CD-ROM formats that have evolved since 1986 from the CD-DA (digital audio) format constitute a maddening alphabet soup, ranging from CD-ROM XA for extended architecture) to CD-I (for interactive) to CD Extra (also known as Enhanced CD, which accommodates audio and data tracks in a fashion that permits the audio to be played on a plain vanilla CD player).
