  2. Data compression - Wikipedia

    en.wikipedia.org/wiki/Data_compression

    MP3, an example of a lossy file format compared to WAV. In the late 1980s, digital images became more common, and standards for lossless image compression emerged. In the early 1990s, lossy compression methods began to be widely used. [13] In these schemes, some loss of information is accepted as dropping nonessential detail can save storage space.

    This method is commonly referred to as perceptual coding or psychoacoustic modeling. [13] The remaining audio information is then recorded in a space-efficient manner using MDCT and FFT algorithms. Compared to CD-quality digital audio, MP3 compression can commonly achieve a 75–95%

  4. Lossy compression - Wikipedia

    en.wikipedia.org/wiki/Lossy_compression

    In information technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storing, handling, and transmitting content. The different versions of the photo of the cat on ...

  5. Audio file format - Wikipedia

    en.wikipedia.org/wiki/Audio_file_format

    Audio file format. 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 ...

  6. Advanced Audio Coding - Wikipedia

    en.wikipedia.org/wiki/Advanced_Audio_Coding

    Advanced Audio Coding is designed to be the successor of the MPEG-1 Audio Layer 3, known as MP3 format, which was specified by ISO / IEC in 11172-3 (MPEG-1 Audio) and 13818-3 (MPEG-2 Audio). Blind tests in the late 1990s showed that AAC demonstrated greater sound quality and transparency than MP3 for files coded at the same bit rate.

  7. Lossless compression - Wikipedia

    en.wikipedia.org/wiki/Lossless_compression

    Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. [1] By contrast, lossy compression permits reconstruction only of an approximation of ...

  8. Audio compression - Wikipedia

    en.wikipedia.org/wiki/Audio_compression

    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. Dynamic range compression, also called audio level compression, in ...

  9. Sub-band coding - Wikipedia

    en.wikipedia.org/wiki/Sub-band_coding

    Sub-band coding. In signal processing, sub-band coding ( SBC) is any form of transform coding that breaks a signal into a number of different frequency bands, typically by using a fast Fourier transform, and encodes each one independently. This decomposition is often the first step in data compression for audio and video signals.
