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.
