I used this software a few years ago now, it might have been a Winamp plugin or it might have been standalone, I'm not sure. It was basically just an equalizer but had a bunch of excellent presets for making your MP3s sound like old vinyls, gramophones and the like, all wrapped in a really attractive GUI. I'm sure you can get similar effects messing about with other equalizers but this one was far simpler to use and had a load of extra effects you don't get with most others. Anyone have a clue?
