Wavpack is supposed to work with shntool but it appears that it no longer has full functionality with shntool since wavpack v.4.0 came out. I would expect that a new edition of shntool will come out in the near future to accomodate this.

You can, however, produce shntool output in wavpack 4.0+ format (4.2 is the current version). It is only input from 4.0+ files that shntool cannot currently handle. This, of course, means that you can't check wavpack 4.0+ files for SBEs w/o converting them to some other format.

If you mean does wavpack operate like flac, shn etc, the answer is yes it does. Wavpack has Win32 binaries available at its website that work with Multi-frontend and there is a special Wavpack Frontend like FLAC Frontend made by Speek. The only difference is that wavpack uses two separate binaries, one for encoding and one for decoding.

Making or decoding wavpack files is every bit as simple as dealing with shn, flac or ape. When making wavpack files I recommend you use '-hm' as your only command-line switch. The 'h' means 'high quality' which basically means high compression, and the 'm' tells the encoder to put a wave md5 fingerprint inside the headers.
