2. Audio file format - Wikipedia

   en.wikipedia.org/wiki/Audio_file_format

   Standard audio file container format used mainly in Windows PCs. Commonly used for storing uncompressed , CD-quality sound files, which means that they can be large in size—around 10 MB per minute. Wave files can also contain data encoded with a variety of (lossy) codecs to reduce the file size (for example the GSM or MP3 formats).

3. Data compression ratio - Wikipedia

   en.wikipedia.org/wiki/Data_compression_ratio

   Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:

4. Shorten (codec) - Wikipedia

   en.wikipedia.org/wiki/Shorten_(codec)

   Shorten (SHN) is a file format used for compressing audio data. It is a form of data compression of files and is used to losslessly compress CD-quality audio files (44.1 kHz 16-bit stereo PCM). Shorten is no longer developed and other lossless audio codecs such as FLAC, Monkey's Audio (APE), TTA, and WavPack (WV) have become more

5. WavPack - Wikipedia

   en.wikipedia.org/wiki/WavPack

   WavPack compression can compress (and losslessly restore) 8, 16, 24, and 32-bit fixed-point, and 32-bit floating-point PCM audio files in the .WAV file format. It can also handle DSD input in DSDIFF or DSF format. [2] It also supports surround sound streams and high sampling rates. Like other lossless compression schemes, the data reduction ...

6. Data compression - Wikipedia

   en.wikipedia.org/wiki/Data_compression

   When audio files are to be processed, either by further compression or for editing, it is desirable to work from an unchanged original (uncompressed or losslessly compressed). Processing of a lossily compressed file for some purpose usually produces a final result inferior to the creation of the same compressed file from an uncompressed original.

7. Audio coding format - Wikipedia

   en.wikipedia.org/wiki/Audio_coding_format

   An audio coding format [1] (or sometimes audio compression format) is a content representation format for storage or transmission of digital audio (such as in digital television, digital radio and in audio and video files). Examples of audio coding formats include MP3, AAC, Vorbis, FLAC, and Opus.

8. Compressed audio optical disc - Wikipedia

   en.wikipedia.org/wiki/Compressed_audio_optical_disc

   A standard audio CD (74 minutes) can hold about 18 audio programs, a 650-MB data CD (equivalent to 74-minute audio CD) containing mid-quality (160-kb/s) audio files can hold approximately 9.5 hours of audio or about 138 audio tracks. ID3 tags stored in compressed audio files can be displayed by some players, and some players can search for ...

9. Lyra (codec) - Wikipedia

   en.wikipedia.org/wiki/Lyra_(codec)

   The Lyra codec is designed to transmit speech in real-time when bandwidth is severely restricted, such as over slow or unreliable network connections. [1] It runs at fixed bitrates of 3.2, 6, and 9 kbit/s and it is intended to provide better quality than codecs that use traditional waveform-based algorithms at similar bitrates.
