I need to convert a bunch of .wv files to .flac but I can't seem to find a program to do it. Does anybody know how I can do this?

P.S.: I was wondering why Audacity does not support the importing .wv format if it is open source and lossless. Does anybody know?

Update: Somewhere I read about converting .ape to .flac using ffmpeg, so I decided to try replacing the .ape with .wv and at first it seems to work but then I get this at the end:

[wv @ 0x8e7c200] Invalid block header.te= 836.1kbits/s    
audiofile.wv: Invalid data found when processing input

So my question is: what is wrong here?

By the way, the command used was ffmpeg -i audiofile.wv audiofile.flac. Thanks for the help.

The ffmpeg error you're getting makes me think you might just have a corrupted file. You could try sox audiofile.wv audiofile.flac. Alternatively, you could use the wavpack tools:

wvunpack audiofile.wv -o - | flac - -o audiofile.flac

Note that wiill not copy over any metadata; you'll need to do that separately.

If even the wavpack tools can't successfully read the file, then your file is probably just corrupt.


If you don't mind using command lines, you could use ffmpeg. If you simply run:

ffmpeg -i file.wv -acodec flac file.flac

(Assuming of course the file you want to convert is called "file.wv"), will produce a file called file.flac. Of course, if you want to, you can change that last bit of the command so that ffmpeg outputs a different filename.

Or, if you at least have the ffmpeg libraries installed, you should be able to import the wavpack files into Audacity.

  • OP already mentions having tried ffmpeg (though probably OP edited it in while you were writing your answer)

  • "Invalid data found when processing input", ffmpeg 6.0, while wvunpack processed it well Jun 9, 2023 at 12:18
