This took only a few seconds to convert a 45 minute video, which was had only upload 10% to Online Audio Convertor. You do have to install FFMpeg but this is free, cross platform and open source.

select the Quality setting (192kps or 128kps).I was lucky enough to stumble across the following site It is possible to open a m4a file in Audacity and export to ‘mp3’ but you need to install the separate ffmpeg library, which handles video files. ‘m4a’ seems to be supported by iTunes but ‘mp3’ is the recommended format by most podcasting sites and apps.
It often has better audio quality and compression than mp3 but isn’t always supported by audio playback software. Which is why many video software output ‘m4a’ rather than ‘mp3’. The MPEG-4 file format ‘mp4’, normally associated with video encoding, when it only includes audio information is an ‘.m4a’ file. It seems like it should be such a simple thing to do.
