  2. Comparison of audio coding formats - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_audio_coding...

    The 'Music' category is merely a guideline on commercialized uses of a particular format, not a technical assessment of its capabilities. 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.

  3. Audio file format - Wikipedia

    en.wikipedia.org/wiki/Audio_file_format

    Audio file icons of various 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.

  4. Windows Media Audio - Wikipedia

    en.wikipedia.org/wiki/Windows_Media_Audio

    When decompressed, the audio signal is an exact replica of the original. The first version of the codec, WMA 9 Lossless, and its revisions support up to 96 kHz, 24-bit audio for up to 6 discrete channels (5.1 channel surround) with dynamic range compression control. The typical compression ratio for music varies between 1.7:1 and 3:1. [40] [41 ...

  5. Audio coding format - Wikipedia

    en.wikipedia.org/wiki/Audio_coding_format

    A lossless audio coding format reduces the total data needed to represent a sound but can be de-coded to its original, uncompressed form. A lossy audio coding format additionally reduces the bit resolution of the sound on top of compression, which results in far less data at the cost of irretrievably lost information.

  6. Audio codec - Wikipedia

    en.wikipedia.org/wiki/Audio_codec

    An audio codec, or audio decoder is a device or computer program capable of encoding or decoding a digital data stream (a codec) that encodes or decodes audio. [1] [2 ...

    [19] [20] A stable version (1.0) of the reference software was released on July 19, 2002. [ 21 ] [ 22 ] [ 23 ] Since February 2013, [ 24 ] Xiph.Org has stated that the use of Vorbis should be deprecated in favor of the Opus codec, which is also a Xiph.Org Foundation project and also free and open-source.

  8. Audio compression - Wikipedia

    en.wikipedia.org/wiki/Audio_compression

    Audio compression may refer to: Audio compression (data) , a type of lossy or lossless compression in which the amount of data in a recorded waveform is reduced to differing extents for transmission respectively with or without some loss of quality, used in CD and MP3 encoding, Internet radio, and the like

  9. Transparency (data compression) - Wikipedia

    en.wikipedia.org/.../Transparency_(data_compression)

    In data compression and psychoacoustics, transparency is the result of lossy data compression accurate enough that the compressed result is perceptually indistinguishable from the uncompressed input, i.e. perceptually lossless. A transparency threshold is a given value at which transparency is reached. It is commonly used to describe compressed ...
