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.
WavPack features include:
- Compatible with virtually all PCM audio formats including 8, 16, 24, and 32-bit ints; 32-bit floats; mono, stereo, and multichannel; sampling rates from 6 to 192 kHz (and non-standard rates)
- Multiplatform support including Windows, Linux, and OS X, plus a Flash decoder and Silverlight decoder that can work virtually anywhere, and now a web-based audio converter that can decode WavPack files online
- Instantly seekable and streaming capable (and gapless)
- ReplayGain (including WavPack file scanner and compatible plugins)
- Uses ID3v1 and APEv2 tags for metadata (including ReplayGain)
- 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
Dynamic noise shaping (dns) for optimum quality at lower hybrid bitrates
- Hybrid mode now operates as low as 2.25 bits/sample (or 196 kbps for CD audio)
- Free and open source with easy to use C library API and unrestrictive license (BSD)
- Intuitive command line interface (with wildcards and destination directory)
- Small, efficient executable (no large programs or dlls to install)
- Special "low latency" version available for custom applications
- Self-extracting archives with cuesheets (Windows only)
- Java and C# decoders and encoders available
- Fully backward compatible to WavPack 1.0
- Complete piping support... More Info »
