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 and 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%.

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!

Features of WavPack 4.7:

- 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 encoder and a 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

Changes in WavPack 4.70:

WavPack frontend 2.0: You really need this graphical user interface for command-line encoder and decoder. If you get an error when you try to run the frontend, you need one of the following files (the error message indicates which one): Visual Basic 6 Runtime files, mscomctl.ocx or tabctl32.ocx.

CoreWavPack: is a set of DirectShow filters to support the WavPack Audio Codec that allows playing WavPack files (.wv .wvc) in any DirectShow based media player.

Ogg Vorbis: is a high-quality lossy audio codec which is free of intellectual property restrictions (like those surrounding MP3).

FLAC: is similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality.
