v. t. e. Compact Disc Digital Audio ( CDDA or CD-DA ), also known as Digital Audio Compact Disc or simply as Audio CD, is the standard format for audio compact discs. The standard is defined in the Red Book, one of a series of Rainbow Books (named for their binding colors) that contain the technical specifications for all CD formats.
An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression. The data can be a raw bitstream in an audio coding format, but it is ...
Timeline of audio formats. An audio format is a medium for sound recording and reproduction. The term is applied to both the physical recording media and the recording formats of the audio content βin computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store the data.
The compact disc ( CD) is a digital optical disc data storage format that was co-developed by Philips and Sony to store and play digital audio recordings. It uses the Compact Disc Digital Audio format which typically provides 74 minutes of audio on a disc. In later years, the compact disc was adapted for non-audio computer data storage purposes ...
For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint. First public release date is first of either specification publishing or source releasing, or in the case of closed-specification, closed-source codecs ...
FLAC is specifically designed for efficient packing of audio data, unlike general-purpose lossless algorithms such as DEFLATE, which are used in ZIP and gzip. While ZIP may reduce the size of a CD-quality audio file by 10β20%, FLAC is able to reduce the size of audio data by 40β50% by taking advantage of the characteristics of audio.
1. a null byte (binary value 0) The size of a CDA file being fixed, as well as its organization, there is always only one and only chunk, named "CDDA" (meaning compact disc for digital audio ). The identifier created by Windows is used by the Windows 95 and Windows 98 CD drive (cdplayer.exe). This player cannot connect to FreeDB or CDDB.
It compresses an audio CD to a range of 206 to 411 MB, at bit rates of 470 to 940 kbit/s. The result is a bit-for-bit duplicate of the original audio file; in other words, the audio quality on the CD will be the same as the file when played back. WMA Lossless uses the same .WMA file extension as other Windows Media Audio formats.
