WavPack Win32 4.4

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, 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%.


WavPack 4.40 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
* 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
* 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 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)
* Self-extracting archives with cuesheets (Windows only)
* Fully backward compatible to WavPack 1.0
* Complete piping support
