How can I make an MP3 sound as if it is being played on a record player?<br/><br/> I need to get a song to sound as if it is being played off a record player. I've been using a software called Audacity.<br/><br/> Any other suggestions?

What sound are you specifically trying to achieve? Are you looking to be able to "scratch" the music like is done for some remixes? Or are you just trying to overlay a sound of the needle?
