How can I batch convert flac files to wav?

Question

I'm using Windows XP, and I have several (about 160) flac files which I need to convert to wav. Since it is not practical to convert so many one by one, I need a utility that can convert them, but also preserve the metadata. It is crucial that the metadata is present and not altered, and I would highly prefer anything portable (sans-installation), and command line utilities would help too.

Thank you for helping

==EDIT== I don't need the metadata, can this conversion be done now, somehow?

Solution

The default flac distribution include a binary called flac(.exe). You can decompress flac files with it using the -d option.

Just use the cmd shell from the folder with .flac files:

FOR %f IN (*.flac) DO "C:\Program Files (x86)\FLAC\flac.exe" -d "%f"

Uhm, WAV has very limited metadata support you know? It simply can't handle everything that can be stored in a flac file.

Thank you, this is just what I needed. It also has an option to write to STDout (EXACTLY what I needed), so this is perfect.

I have encountered difficulties when feeding the output from flac into lame. The duration of the mp3 files comes out wrong sometimes. It's possible to recalculate the length of VBR mp3s using some utility (e.g foobar2000), but I find it generally safer to use intermediate wav files.
