Extracting Audio from Uncompressed *.mov Files

Hi, I have digitized an old audiotape on Mac with Formac DVStudio (analog audio/video to FireWire DV converter) and old analog tape player. Strangely enough, supplied Formac AudioWizard is able to create only *.mov file without video. The question is how to extract audio from uncompressed *.mov files and convert it to mp3 on Linux, where I have moved them? Thanks in advance. Andrei
