WV to SPH Converter

WavPack is an open-source audio codec created by David Bryant, with version 1.0 released on August 15, 1998. What sets WavPack apart is its unique hybrid mode: the encoder can simultaneously produce a compact lossy file and a separate correction file that, when combined, reconstruct the original PCM stream bit-for-bit. Users who need portability carry just the lossy file; those who want archival quality keep both. The codec handles PCM audio from 8-bit to 32-bit integer and 32-bit floating point, with sample rates up to 768 kHz — specifications broad enough for DSD content, which WavPack 5 added support for. Compression ratios in pure lossless mode typically reach 40 to 55 percent of the original size, competitive with FLAC and often slightly better on certain material. Multicore encoding in later versions dramatically speeds up processing on modern hardware. The open-source library ships under a BSD license and has been integrated into foobar2000, VLC, FFmpeg, and numerous other tools. WavPack also supports rich metadata through APEv2 tags, embedded cue sheets, and ReplayGain values, covering the organizational needs of even the most meticulous music library.
