Hi--I am not technologically up on this and need to know how to make a digital file (MP3 format) of my voice for a Podcast that a magazine is creating that is using some of my work--anyone know what I need for my laptop? I need a file that I can email. I'm not sure my description even makes sense. Is there some freeware that will make a file for me if I get a microphone? I don't need to enhance it or anything--I just need to record myself reading. TIA
