...... into the world of making my own mp3s... MAN do I have questions... ...

I don't have the keyboard to PC hookup yet..
So I recorded my self on tape (don't laugh), recorded that to disc using a Phillips 880, and now I'd like to convert that to mp3 ... I believe I have to go to a wav file first? ... if so, is the freeware I can get for this? .....
thnx,
t.
