WavPack

WavPack is a versatile, fully open-source audio compression format. It offers three distinct modes: perfect lossless compression for archiving, high-quality lossy compression for efficient storage, and a unique hybrid mode. The hybrid mode combines a small, high-quality lossy file with a correction file, enabling both space-saving playback and the ability to later restore the original audio perfectly. This flexibility makes WavPack ideal for music enthusiasts, archivists, and professionals who need to balance quality and file size for a wide range of media applications.
