WavPack

[2] A similar "hybrid" feature is also offered by OptimFROG DualStream, MPEG-4 SLS and DTS-HD Master Audio.

The official WavPack website offers plugins for Winamp, Nero Burning ROM, MediaChest 2.1, and several other applications, as well as a DirectShow filter.

[9] dBpoweramp CD-Ripper,[10] by the author of foobar2000, as well as foobar2000[11] itself, and Asunder allow ripping Audio CDs directly into Wavpack files.

It can only produce version 4 bitstreams, which do not support fast verification for file integrity checks, or more than 16 channels.

Due to lack of support for Hybrid mode, FFmpeg-based playback software will fail to consider the .wvc correction file if there is one present, and will play or transcode only the lossy section.

For the default mode a simple adaptive factor is added to weigh the influence of the earlier sample on the prediction.

The second advantage is that it is easily adaptable to lossy encoding, since all significant bits (except the implied "one" MSB) are transmitted directly.

In the "fast" mode the output of the non-adaptive decorrelator is simply rounded to the nearest codable value for the specified number of bits.

It is possible that a lossless compressor that used floating-point math could generate different output when running on that faulty Pentium.

Even disregarding actual bugs, floating-point math is complicated enough that there could be subtle differences between "correct" implementations that could cause trouble for this type of application.

[15] A 32-bit error detection code to the generated streams is included to maintain user confidence in the integrity of WavPack's compression.

It works on many architectures, including x86, ARM, PowerPC, AMD64, IA-64, SPARC, Alpha, PA-RISC, MIPS and Motorola 68k.

A cut-down version of WavPack was developed for the Texas Instruments TMS320 series Digital Signal Processor.

This was aimed predominantly at encouraging manufacturers to incorporate WavPack compression (and de-compression) into portable memory audio recorders.

Some "special" features of the full WavPack software were included (ability to generate a correction "file" (stream), for example), and others were excluded.
