		WavPack development is still going on, and a major feature added in late 3.x versions is the hybrid mode, where the encoder generates a lossy file + a correction file, so that both can be decompressed back to the original PCM stream.
		The first advantage of WavPack's coder is that it does not require the data to be buffered ahead of encoding, instead it converts each sample directly to bitcodes.
		The developer has decided to not use any floating-point arithmetic in WavPack's data path because he believes that integer operations are less susceptible to subtle chip to chip variations that could corrupt the lossless nature of the compression, the Pentium floating point bug being a blatant example of this.

	wavpackenc
		Wavpack is an open-source audio codec that features both lossless and lossy encoding.
		The audioconvert element is needed as the Wavpack encoder only accepts input with 32 bit width (and every depth between 1 and 32 bits).
		This pipeline encodes audio from an audio CD into a Wavpack file using lossy encoding at a certain bitrate (the file will be fairly small).

		Another advantage of wavpack lossy 384+kb/s is that it can be transcoded to other codecs without a discernable loss of quality compared to the original source.
		But nonetheless, WavPack is a very flexible codec and can give the user a lot of choice that way, and is still very competitive in all respects, any way you slice it.
		if some device "supports" wavpack but cannot handle all the modes because some require too many mips, and this is not clear to users and the decoder, there are going to be customer support problems.

	WinZip® - Additional Compression Methods Specification
		WavPack is an open-source lossless audio compression format developed by David Bryant.
		If you tell WavPack that the sample size is only 12-bits, it will ignore the 4 unused bits during compression and set them to 0 on extract, regardless of what they were set to in the original file.
		Instead, telling WavPack that the sample size is the full 16-bits instead of the actual 12-bits is necessary to insure that the file extracts to one that is bit for bit identical to the original

	WavPack User Documentation
		WavPack normally defaults to joint stereo (sometimes called mid/side) in which the left and right channels are combined to form an alternate representation (essentially L+R and L-R) that compresses better in lossless mode and improves quality in lossy mode.
		Because WavPack must seek to the beginning of the file to write the correct length, this option cannot be used with piped output.
		WavPack uses first-order noise shaping to improve the perceived quality of lossy files and to improve the hybrid lossless compression ratio.

		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 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.

		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.

	WavPack - Hydrogenaudio Knowledgebase
		WavPack (pronounced "wave-pack") allows users to compress (and restore) 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.
		In 1999, the developer released version 3.0, which featured novelties such as a fast mode (with reduced compression ratio), compression of RAW files and error detection using CRC checksums.
		It's worth mentioning the Matroska guys decided to concentrate on WavPack as the lossless compressor of choice for their container.
