Convert wavpack hybrid to wavpack standard
Folks,

I have a lot of wavpack hybrid tracks. I'm finding that dealing with the two files for each track is cumbersome.  I'm looking for a way to convert these wavpack hybrid file pairs back to the single *.wv lossless files, while keeping the tags intact. Does anyone know of a good Linux solution. Command line is preferred but a gui is alright. 

I've googled this and nothing seems to work well.

Thanks

making an example encode
   
Code: [Select]
wavpack -b2 -c -w "sometag=VaLuE" file.wav

(will generate file.wc and file.wvc with sometag=VaLuE)

   
Code: [Select]
ffmpeg_static -i file.wv whatever.wv

(will generate whatever.wv with sometag=VaLuE)

Using ffmpeg from http://johnvansickle.com/ffmpeg/

I'am sure there is a way with just wavpack tools, but too dumb to understand the wavpack man.

------------------------------------------

edit: ok, with wavpack 4.75 a simple
Code: [Select]
wavpack file.wv -o whatever.wv

is working just fine.

or convert all *.wv to subdir ./out
Code: [Select]
wavpack *.wv -o ./out

I'd use caudec, because it will be automatically using n threads, just like foobar on windows. It also uses /tmp to get around HDD limitations. Tags are kept, as well.

Code: [Select]
caudec -c wv -q hx6 -o /my/output/dir *.wv

Currently, I'm using DeadBeef to convert hybrid Wavpack to MP3 under LXLE (a variant of Lubuntu) and so far so good: it's been working like a charm, tags and everything!

So I can't see why it wouldn't do the same flawlessly to your required hybrid-to-lossless conversion.

Edit: as I'd previously posted elsewhere on HA, I made sure the correction files were actually being recognized by DeadBeef during conversion* - or else I could've ended up with MP3 files resulting from lame lossy-to-lossy conversion.



*which, unfortunately, (and thanks to some arcane reason) wasn't the case with my copy of foobar2000 under Wine.

The only thing I can add is that it's possible do do this in place (if you have the stomach, although it should be safe because tmp files are always used and the output is verified before the source is deleted):

Code: [Select]
wavpack -vdy *.wv


or even something like this (although too many files will create problems for the shell):

Code: [Select]
wavpack -vdy *.wv */*.wv


Note that the -d is not normally required when overwriting the original file, but is required here to delete the .wvc files (although you could easily delete them manually afterwards too).

And, of course, you might want to use some other encoding mode options (-h, etc.). Note that this will not use multiple threads.

Note that the second example is Linux only (not Windows), and that you can use this same format to convert back to hybrid if you change your mind again (and then the -d would be redundant).

Good luck!

edit: fixed typo in second example and added final note

@bryant, nice about the overwrite, but how deep should that */wv */*.wv glob traverse?

Code: [Select]
ls */mp3 */*.mp3 | wc -l
ls: dostop do */mp3 ni mogoč: No such file or directory
407

find . -type f \( -iname "*.mp3" ! -path "*.Apple*" \) | wc -l
1911

ls */*.mp3 **/*.mp3 | wc -l
814

Pretty sure only find gets them all (GNU bash, version 4.2.37(1)-release (x86_64-pc-linux-gnu)).

I had a typo in my original example which I also fixed in your quote (hope that's not against the rules ), but yeah, I have not figured out a way to traverse recursively just using the shell like that. But in reality I would just go one level deeper every command until I got no files (and would do an "ls" first at each level to make sure something funny wasn't going to happen). I quite often use grep like that when I'm looking for things is large source trees.

Ideally I should have a --recursive option, but I'd be a little hesitant to implement that...

I think a few find examples in man should be enough, + advanced would be something like parallel, I have this example noted:

Code: [Select]
parallel --gnu mpcenc {} {.}.mpc ::: *.flac

Unless I guess stuff like this is out of the man scope for specific thingy.

Wow, thanks, I had never heard of the parallel command!

I will experiment with that and see how well it works doing batch WavPack operations with multiple threads.

Apparently my post didn't take last night.  Thanks all for your suggestions. Bryant's works great. I had no idea that Wavpack preserved tags! That's makes me love it even more.

Hi, longtime lurker here.

First of all, I want to thank bryant, and I love wavpack, etc, etc.

A couple of months ago, I ran into a similiar problem the OP did. I then discovered GNU Parallel (as previously mentioned,) and wrote a shell script for batch encoding. I'll leave it here in case anyone would like to use it.

@rdtsh; No bashism detected (checkbashisms (in jessie devscripts)), so I guess it should work on most shells? (Thanks for sharing, quite an elaborate script).
p.s. There are some 'comments' if you paste the script to http://www.shellcheck.net

I'm just using zsh (bash compatable).  I made a postbin of the code here https://gist.github.com/dc4e4a151a81f2e17db4  but doing a diff on it and your code, i only changed that line.

Thanks for showing me shellcheck. I wrote the script after reading the O'Reilly book "Classic Shell Scripting", so everything should be POSIX. About the two comments in shellcheck:
    1)
        There's some bug in parallel that won't let it take a shell function as an argument. I could have put the meat of the script into a seperate file, but that would have been silly.
    2)
        I put the backslash in there so that the line wouldn't go over 80 characters. If it weren't in quotes, it wouldn't matter, and that is how parallel sees it. Parallel's fine with it, so I don't see a problem with it.

I did notice a somewhat redundant 'printf' on line 164 though.

@BearcatSandor
I figured it was some shell issue. It's probably the '-' in the crunchbang. That tells the shell not to take any additional arguments (security feature); it must mess zsh up.

There's a special debug feature built into the WavPack command-line programs that might help debug issues like this. You create a copy of the binary with "_debug" appended to the name (like "wavpack_debug") and when you use that it will dump its command-line arguments to stderr when it's run, one arg per line. It also dumps some other info, but this look like an args problem.

Also, I noticed you're still using the 4.70 version...there's a new faster one available, you know!

@Bryant  Well,  I'm on Gentoo which can be a bit conservative in some ways and some packages like wavpack don't get a lot of love.

@rdtsh I'll try the script in plain old bash and see what it does.

Bash isn't plain. Try dash, it only does POSIX with a few BSD extensions (It's what /bin/sh links to in Debian by default.) I think that my earlier hypothesis was wrong, as I didn't notice the wavpack copyright stuff.

1- I highly doubt that your /bin/sh is actually zsh.

2- zsh is not bash-compatible, it's neither a superset, nor a subset. Example:
Code: [Select]
a=b; b=c; echo "${(P)a}" # zsh syntax
a=b; b=c; echo "${!a}" # bash syntax


3- Do you happen to have a file that starts with a dash?

All of my files start with numbers, as i prepend the disc number to the file name.

I just switched to bash via "bin/bash" at my cli  and ran the command. i get the same results with /bin/bash and /bin/dash

Thanks for the help so far folks. I really do appreciate it.

Your interactive shell is irrelevant. The script has a shebang(the 1st line) that calls /bin/sh.

Anyway, I don't think what /bin/sh links to is relevant here.
Sharing more of the output you get should help us figure out what's really going on.

Yes, I know the adoption is pretty slow in some distros. Raspian (Debian/ARM) is still on 4.60 which has bug there (because of default unsigned chars) that causes high and very high modes to produce corrupt files. 

But it's pretty safe to build a static version locally (--disable-shared) and install it in the default location (/usr/local/bin). You can undo it by deleting those three files. That will also make it easy to try the "wavpack_debug" trick I described above and see the actual args being passed.
