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 4.0 format has been designed from the ground up to offer unparalleled performance and functionality. Features:

- Compatible with virtually all PCM audio formats including 8, 16, and 24-bit ints; 32-bit floats; mono, stereo, and multichannel; sampling rates from 6 to 192 kHz
- Multiplatform support including Windows, Linux, and OS X
- Instantly seekable and streaming capable
- Error-tolerant block format conducive to hardware decoding
- Optional "asymmetrical" mode for improved compression
- MD5 audio checksums for verification and identification
- Unique hybrid mode (provides high quality lossy + "correction" file)
- Hybrid mode now operates as low as 2.25 bits/sample (or 196 kbps for CD audio)
- Free and open source with easier to use library interface and unrestrictive license (BSD)
- Intuitive command line interface (with wildcards and destination directory)
- Small, efficient executable (no large programs or dlls to install)
- Fully backward compatible to WavPack 1.0
- Self-extracting archives (Windows only)
