  2. Dynamic range compression - Wikipedia

    en.wikipedia.org/wiki/Dynamic_range_compression

    Dynamic range compression (DRC) or simply compression is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal's dynamic range. Compression is commonly used in sound recording and reproduction, broadcasting, [1] live sound reinforcement and some ...

  3. WAV - Wikipedia

    en.wikipedia.org/wiki/WAV

    All WAV files, even those that use MP3 compression, use the .wav extension. This is a reference to compare the monophonic (not stereophonic) audio quality and compression bitrates of audio coding formats available for WAV files including LPCM, ADPCM, Microsoft GSM 06.10, CELP, SBC, Truespeech and MPEG Layer-3. These are the default ACM codecs ...

  4. 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.

  5. μ-law algorithm - Wikipedia

    en.wikipedia.org/wiki/Μ-law_algorithm

    Given that the precision of the detail is compromised anyway, and assuming that the signal is to be perceived as audio by a human, one can take advantage of the fact that the perceived acoustic intensity level or loudness is logarithmic by compressing the signal using a logarithmic-response operational amplifier (Weber–Fechner law). In ...

  6. 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 ...

  7. List of codecs - Wikipedia

    en.wikipedia.org/wiki/List_of_codecs

    Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary.

  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. 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.
