LOUKASH  An excellent tool for helping to make vinyl recordings sound better.

If you are used to work with standard audio editors and plugins, DeNoise may need some time to get used to it; the interface might need some improvement, too. But once you have figured it all out, the results are amazing. Along with CLickRepair from the same developer it can help to make rare recordings enjoyable again, which you would have likely trashed in their original vinyl state.

It's also important to point out Brian Davies' excellent and almost instant support.
