  How do I create an m3p file with the output of the Mac "say" command? [closed] - Oussama L. Newest 'ffmpeg' Questions - Stack Overflow
  I want to read a very long text with the SAY mac's command (say -f file.txt), and to record the output to file.mp3.

I don't really need to listen to it, so if there is a way to directly have an mp3 file just by hitting enter, it would be great..
