     1.4 +WavPack is a completely open audio compression format providing lossless,
     1.5 +high-quality lossy, and a unique hybrid compression mode.
     1.6 +
     1.7 +In the default lossless mode WavPack acts just like a WinZip compressor
     1.8 +for audio files. However, unlike MP3 or WMA encoding which can affect the
     1.9 +sound quality, not a single bit of the original information is lost, so
    1.10 +there's no chance of degradation. This makes lossless mode ideal for
    1.11 +archiving audio material or any other situation where quality is paramount.
    1.12 +The compression ratio depends on the source material, but generally is
    1.13 +between 30% and 70%.
    1.14 +
    1.15 +The hybrid mode provides all the advantages of lossless compression with an
    1.16 +additional bonus. Instead of creating a single file, this mode creates both
    1.17 +a relatively small, high-quality lossy file that can be used all by itself,
    1.18 +and a "correction" file that (when combined with the lossy file) provides
    1.19 +full lossless restoration. For some users this means never having to choose
    1.20 +between lossless and lossy compression!
    1.21 +
    1.22 +WavPack employs only well known, public domain techniques (i.e., linear
    1.23 +prediction with LMS adaptation, Elias and Golomb codes) in its
    1.24 +implementation.
    1.25 +Methods and algorithms that have ever been patented (e.g., arithmetic
    1.26 +coding, LZW compression) are specifically avoided. This ensures that WavPack
    1.27 +encoders and decoders will remain open and royalty-free.
