What is WV? WavPack Audio Format Explained
An open audio format offering lossless, lossy, and a unique hybrid compression mode.

What is WV?
WV is the file extension for WavPack, a free and open-source audio compression format created by David Bryant and first released in 1998. WavPack can compress audio losslessly, in a high-quality lossy mode, or in a distinctive hybrid mode that combines the benefits of both.
In its standard mode, a .wv file is fully lossless. In hybrid mode, WavPack splits the audio into a relatively small lossy .wv file that is usable on its own, plus a separate .wvc correction file that, when combined with the .wv file, restores the audio losslessly. The format supports 8-, 16-, 24-, and 32-bit integer and 32-bit floating-point PCM, multichannel and surround audio, and native DSD in WavPack 5.
How WavPack Works
WavPack can operate in three ways: a fully lossless mode, a high-quality lossy mode, and a distinctive hybrid mode.[1] In hybrid mode the encoder produces a relatively small lossy .wv file that plays on its own, plus a separate .wvc correction file that recombines with it to restore the audio losslessly.[2]
History and Standardization
WavPack is a free and open-source format created by David Bryant and first released in 1998.[2] Its reference encoder, decoder, and documentation are published openly, supporting third-party integration into players and tools.[1]
Technical Details
The format handles 8-, 16-, 24-, and 32-bit integer and 32-bit floating-point PCM, along with multichannel and surround audio.[1] WavPack 5 added native DSD support, extending the format beyond conventional PCM workflows.[2]

WV vs Other Audio Formats
| Feature | WV | FLAC | ALAC |
|---|---|---|---|
| Compression | Lossless & hybrid[1] | Lossless | Lossless |
| Hybrid mode | Yes[1] | No | No |
| License | Open (BSD)[2] | Open | Open |
| Developer | David Bryant[2] | Xiph.Org | Apple |
| Device support | Limited | Wide | Apple-centric |
| Best for | Hybrid lossless | Lossless archiving | Apple lossless |
WavPack offers a unique hybrid lossless mode, though FLAC remains the more widely supported lossless choice.
Advantages & Disadvantages
Advantages
WavPack can produce a small playable lossy file plus a correction file, giving both a compact version and lossless recovery.
The format and reference implementation are released under a permissive BSD license with freely available source code.
It handles 8- to 32-bit integer and 32-bit float PCM, multichannel surround, and native DSD in version 5.
Standard-mode WavPack restores audio bit-perfectly, making it suitable for long-term lossless storage.
Disadvantages
WavPack is less ubiquitous than FLAC, so some hardware players and apps may not support .wv out of the box.
Keeping the .wv and .wvc files together is required for lossless restoration, adding bookkeeping in hybrid workflows.
Its comparatively low profile means fewer guides and tools target WavPack specifically.
Common Use Cases
WavPack suits users who want flexible lossless, lossy, or hybrid audio storage.
Lossless archiving | FileFormer
Standard-mode .wv files store master recordings and CD rips bit-perfectly with strong compression.
Hybrid storage | FileFormer
Hybrid mode lets users keep a small portable lossy file plus an optional correction file for full lossless recovery.
High-resolution and DSD audio | FileFormer
Support for 32-bit float and native DSD makes WavPack useful for high-resolution and audiophile material.

What is the difference between .wv and .wvc files?
The .wv file holds the main WavPack audio (lossless or lossy), while the optional .wvc file is a correction file used in hybrid mode to restore full lossless quality.
Is WavPack lossless?
It can be. In standard mode WavPack is lossless; it also offers lossy and hybrid modes, the latter combining a lossy file with a correction file for lossless recovery.
Who developed WavPack?
WavPack was created by David Bryant, with version 1.0 first released in 1998, and it remains actively maintained as an open-source project.
Is WavPack free to use?
Yes. WavPack is open source under a permissive BSD license, so the format and tools are free for personal and commercial use.
Does WavPack support high-resolution and DSD audio?
Yes. WavPack supports up to 32-bit integer and 32-bit float PCM, multichannel surround, and native DSD storage starting with WavPack 5.
