Several audio formats actually use .cam suffix , so some kind of cam to mp3 conversion is certainly possible. You have to use software suited for your specific format, for example Camtasia uses specific .cam files for projects and export of audio track can be done to MP3 format.
Of course in broad sense, this export might be looked for any cam(era) to mp3 conversions, to produce a voice only file from the recording for example. This can be done with various video editors, but recordings are usually in one of the common formats, for example .mp4.
