As its name suggests, WavPack is used to compress WAV files, and it can accommodate files with multiple channels, at sampling rates from 6 to 192 KHz, and at 8-,16-, 24-, and 32-bit resolution. The compression rate ranges from 30 percent to 70 percent, depending on the source file.
The WavPack encoder offers options for both lossless and lossy compression as well as a ``hybrid'' mode, which creates a lossy compressed file and a second ``correction'' file that can be used to restore the compressed file to its original lossless state. The encoder is available in versions for Windows, Linux, and Mac OS X. All versions are run from a command line, but an optional Windows interface is available.3.9
