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%
|
|
(generally lower for typical popular music and somewhat better for classical
|
|
music and other sources with greater dynamic range).
|
|
|
|
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!
