WavPack is a completely open audio compression format providing lossless,
high-quality lossy, and a unique hybrid compression mode. Although the
technology is loosely based on previous versions of WavPack, the new
version 4 format has been designed from the ground up to offer unparalleled
performance and functionality. In the default lossless mode WavPack acts
just like a WinZip compressor for audio files. However, unlike MP3 or WMA
encoding which can affect the sound quality, not a single bit of the
original information is lost, so there's no chance of degradation. This
makes lossless mode ideal for archiving audio material or any other
situation where quality is paramount. The compression ratio depends on the
source material, but generally is between 30% and 70%. The hybrid mode
provides all the advantages of lossless compression with an additional
bonus. Instead of creating a single file, this mode creates both a
relatively small, high-quality lossy file that can be used all by itself,
and a "correction" file that (when combined with the lossy file) provides
full lossless restoration. For some users this means never having to choose
between lossless and lossy compression! WavPack employs only well known,
public domain techniques (i.e., linear prediction with LMS adaptation,
Elias and Golomb codes) in its implementation. Methods and algorithms that
have ever been patented (e.g., arithmetic coding, LZW compression) are
specifically avoided. This ensures that WavPack encoders and decoders will
remain open and royalty-free.
