Ray Gun for DirectX

From Arboretum Systems:

Ray Gun Automatically cleans up noisy vinyl and tape recordings and has been designed especially for easy and efficient audio archiving and restoration. All you have to do is point, aim and shoot to remove hum, hiss, pops, clicks and other unwanted audio, leaving your original sound intact. Ray Gun will search-and-destroy noise automatically. Use Ray Gun's simple controls to fine-tune the results, then process your new noise-free file. Combining sophisticated pop and click detection with complex spectral analysis, downward expansion, notch filtering and an intelligent "search" function, Ray Gun is like a sci-fi device: small, fast, fun to use and packed with devastating technology.
