  3. Lossless compression - Wikipedia

    en.wikipedia.org/wiki/Lossless_compression

    Some image file formats, like PNG or GIF, use only lossless compression, while others like TIFF and MNG may use either lossless or lossy methods. Lossless audio formats are most often used for archiving or production purposes, while smaller lossy audio files are typically used on portable players and in other cases where storage space is ...

FFmpeg; Pulse-density modulation ...

  7. Data compression - Wikipedia

    en.wikipedia.org/wiki/Data_compression

    Some audio file formats feature a combination of a lossy format and a lossless correction; this allows stripping the correction to easily obtain a lossy file. Such formats include MPEG-4 SLS (Scalable to Lossless), WavPack, and OptimFROG DualStream. When audio files are to be processed, either by further compression or for editing, it is ...

    The intended purpose was to create an open source lossless compression method that was faster and easier to implement than PNG. Figures specified in the blog post announcing the format claim 20-50 times faster encoding, and 3-4 times faster decoding speed compared to PNG, with similar file sizes. [1]
