![]() (Officially, 1 GHz is supported – it is gigaherz, not MHz, the upper limit being in the UHF radio frequency band. High-resolution support for bit depth 1-bit to 32-bit integer and sampling rates up to 2 GiHz in integer steps.DSD support: can losslessly compress Philips DSDIFF and Sony DSF files (see "Using WavPack" below no other end-user codec compresses DSD.) ID3v2.3 tags can be imported.Most of these features are shared with only a few if any notable codecs, or extend to signal types or file types others do not support (comparisons given). Wasted bits detection is also found in FLAC, TAK and OptimFROG. WavPack also handles bit depths not divisible by 8, and is known to employ a "wasted bits" strategy for a signal that is n "actual bits of signal" zero-padded and stored as N bits where certain other codecs may get tricked into a size penalty when the n is not a multiple of 8, or for "fake high resolution" (say the signal is 16 bits, but wrapped in a 24-bit file). In practice, some applications handle embedded cuesheets better in WavPack than in some other formats. Non-audio chunks (RIFF and similar) stored by default, WavPack will not only decode the audio losslessly, but restore the non-audio chunks to file bit-identical to the original.Piping support for encoding, and support for RAW PCM input/output.Multichannel support: currently capped at 256 channels, supports WAVEFORMATEXTENSIBLE channel masks.High-resolution audio support (see next headline).Optional MD5 audio checksum can also be added upon encoding for file fingerprinting. Since version 5, WavPack can also check for corruption without decoding, hence quicker than any decoding format. Error handling: upon playback, it will detect and report corrupted frames, mute to protect against static/noise output, and continue playback.WavPack supports pretty much all the more common features noted at HA Wiki's Lossless Codec Comparison as in the following first list, but several users might consider the more unique features listed under the subsequent headline. 3.2 FFmpeg's WavPack implementation: differences and quirksįor an end-user considering WavPack as an audio format, its feature-richness might be the big selling point.3.1 Splitting WavPack files by cuesheet.3 Using WavPack with 3rd party tools (FFmpeg & more).2.3.5 (To fill in:) Tagging (wvtag) and replaygain management (wvgain).2.3.4 Other file handling: verification / error checking, and other file info (incomplete).2.3.2 (Incomplete:) hybrid lossless & lossy encoding. ![]() 2.2 Basic command line encoding/decoding (for Windows: command-line hints here).2.1 Encoding/decoding by drag and drop (Windows).For more on WavPack, including on its history and technology, see the Wikipedia entry. WavPack has inspired other codecs and their features. In the age of low-power portable Rockbox-equipped players, WavPack could be seen as a reasonable middle ground between FLAC's low CPU footprint and long battery life, and the smaller files but more CPU-intensive Monkey's Audio – invoking WavPacks high mode and extra compression that would compress to smaller sizes than FLAC. Performance-wise, WavPack defaults to a fast codec – less CPU intensive than ALAC, but typically not as fast as FLAC or TAK, especially in decoding CPU usage. ffmpeg's implementation) – and special features might require the user to apply the WavPack executable directly, for example with drag+drop, see the #Using WavPack section below. Everyday use is supported by a wide range of players and taggers, but conversion is likely safest done with applications that invoke the official tools (rather than e.g. ![]() ![]() WavPack is arguably the most feature-rich lossless compressor, supporting a unique range of audio signals including Direct-Stream Digital. WavPack supports and/or can be played back on a large number of platforms/OSes including mobile (Android, iOS), portable ( Rockbox) and even web apps. ![]() Third party implementations are available, including ffmpeg. It is distributed as a free open-source encoder/decoder with a library and a large number of tools, including a Windows GUI and a range of plugins for both audio players and other software. WavPack (pronounced "wave-pack") is a lossless audio codec, also offering optionally a hybrid lossless/lossy mode. ![]()
