I've got a lot of WMA files (non-DRM'ed) that I'd like to convert to mp3 on my Mac, preferrably via the command line.

I can of course use lame to encode the files, so if I can just find a decoder for WMA? Anyone?

Not command line but if you install the free Flip4Mac component and this Lame component you can just open each file in turn with QuickTime Pro and then Export (command-E) straight to Lame. If you have Toast 7/8 but not QT Pro I'm pretty sure you can drop a bunch of WMA files in the Audio window and then then Export them to WAV/AIFF etc but Toast has no direct LAME option.

edit: You can automate this with qt_export from qt_tools. I couldn't work out how to get qt_export to use the LAME component so just sent the output to LAME separately but I'm sure it's possible (--exporter=PYEh ?)

Thanks for the reply.
I have Toast, so at least that's an option, but not the most handy one :-)
I'll look into QT Tools. I haven't got QT Pro, so do you know if QT Tools will still allow me to export?

Edit: QT Tools does work without QT Pro

FFmpeg can decode WMA (and convert directly to LAME MP3). I don't use Macs but I'm pretty sure I've seen OS X builds of FFmpeg before.
