[FFmpeg-user] Converting a cassette audio tape (Lecture) to mp3

[jd1008]

Hi all,
I am running fedora 20 with
ffmpeg version N-51556-ge278500 Copyright (c) 2000-2013 the FFmpeg 
developers
I also installed in /opt
ffmpeg version N-72985-g7c3f7e6 Copyright (c) 2000-2015 the FFmpeg 
developers

I need a set of steps/commands to convert this tape.

I have  plenty of audio tools installed - but not certain what
else I might need.

If anyone has done this before, please share your script.

Kind regards,

JD
