CDDA stands for Compact Disc Digital Audio, which is a standard format for audio CDs (Compact Discs) that contain digital audio. CDDA is a high-quality, uncompressed audio format that uses PCM (Pulse Code Modulation) encoding with a sampling rate of 44.1 kHz and a bit depth of 16 bits per sample.
CDDA files are stored on an audio CD in a specific format that includes a Table of Contents (TOC) and other information about the tracks and disc. The audio data is arranged in a series of sectors, each containing 2352 bytes of data. The first 44 bytes of each sector contain control and error correction information, while the remaining 2304 bytes contain the actual audio data.
CDDA files can be played back on any standard CD player or CD-ROM drive, and can also be ripped (copied) to a computer or other digital storage device using CD ripping software. Once ripped, CDDA files can be saved in various digital audio formats, such as WAV, MP3, or FLAC, depending on the user's needs.
One notable feature of CDDA is its "Red Book" standard, which defines the specifications for audio CDs and ensures that they are compatible with all standard CD players and drives. This makes CDDA a widely accepted and reliable format for audio recording and distribution.
