    en.wikipedia.org/wiki/Vorbis

    Vorbis is a free and open-source software project headed by the Xiph.Org Foundation. The project produces an audio coding format and software reference encoder/decoder for lossy audio compression, libvorbis. [10] Vorbis is most commonly used in conjunction with the Ogg container format [11] and it is therefore often referred to as Ogg Vorbis.

  7. 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.
