| Description | WV (WavPack) is a kind of audio format, which supports lossless and/or high-quality lossy compression. This is a free open-source codec, which compresses files by 30% to 70% depending on the type of music. It is also noteworthy that WV also uses ‘hybrid’ compression mode and creates a high-quality lossy file in combination with a so called ‘correction’ file (.WVC), which is responsible for complete restoration. WV compression pattern compresses/restores 8, 16, 24 and 32-bit files in the WAV format. |
