I have been using a programme called LP Ripper which I found on a coverdisc of a computer magazine. It works on .wav format files and will try to split the track into individual items where it finds quiet sections. If ther are proper spaces between the tracks it does quite a good job. If there is constant noise, you have to select your own positioning, but that is quite straightforward.
I found it a useful programme.
It is NOT freeware - the company website is http://www.cfbsoftware.com/default.htm
Quack!
