Yes, but you can run wvunpack -s *.wv and it'll tell you if the files are lossless or not (see wvunpack_s.txt to see the output).

Anyway, I ran the following test and everything seems perfectly kosher on my end.

First, I got the ffp from the original FLAC files by running metaflac --show-md5sum *.flac (see XM2 - Transmission 4.1.ffp.txt). I then ran shntool len *.flac (see shntool len (flac).txt) and computed the st5s using shntool hash *.flac (see XM2 - Transmission 4.1 (flac).st5)--side note, it's now 'hash' instead of 'md5' to compute st5s.

The next step was to decompress the FLAC files, which was done using flac -d -V *.flac.

From there, I could convert the WAV files to WavPack, which was done with the command wavpack -hm *.wav. I then ran shntool len (see shntool len (wv).txt), shntool hash (see XM2 - Transmission 4.1 (wv).st5), and finally the aforementioned wvunpack -s *.wv on the WavPack files.


As you can see from the text files attached in this post and the next few posts, it worked beautifully--checksums match. Based on my observations, I'm going to put in my recommendation for WavPack to be considered an acceptable format for trading on this site. Others may run tests and see if there are any major hitches I haven't encountered in my test.

Re: Wavpack

This is excellent news. I've been itching to upload my content as wavpack. Just need to wait for a couple of other applications to catch up, some approvals, and away I go.

Re: Wavpack

hopefully we can get support from TLH now that xAct has it. Also support for the command to differentiate lossy from lossless-encoded wavpack in non-command line form is essential. We need full support for the command line-impaired! Then it sounds great to me.

wavpack is a leader, only lossless codec to support 32bit (albeit limited support).
