As far as I can tell ffmpeg is currently not able to use WavePack
correction file when decoding a WavePack track.
It would be great if this could be implemented.
Relevant excerpt from WavePack user documentation:
> If the -c option is specified (in addition to the -b option), then
WavPack will generate an additional file that will contain the information
that was discarded to generate the lossy .wv file. This file will have the
same name as the .wv file but will have the extension .wvc (the 'c' is for
"correction"). When WvUnpack is used to restore the .wav file, it will
attempt to find the .wvc file in the same directory as the .wv file. If it
is found then the decompression will be lossless and will be reported as
such, otherwise lossy decompression will be reported (assuming that any
information was actually discarded during the original compression).
