I want to put my Library Of Congress talking books on the computer. What I need to do is dehiss (cassette tape & machine hiss) the recordings then break them up into 5 minute wav files for burning to audio CD's. Oh & can the software remove rumble & declick for the old talking book records? Is it able to slow the speed down so a book transferred at 16rpm will sound correct as if played at 8rpm? And can the slowed down files be saved? Thanks!
