If you have old records or cassettes that you want to digitize, but don't know what to do about the noise, here's your answer: Izotope RX2. There are definitely cheaper, and darn worthy alternatives such as Bias's SoundSaver and Cakewalk's pyro Audio Creator 1.5, but RX 2 astounded me in my tests for PCWorld's "Digitizing Your Life" feature. One click of a button and my test recording of an old LP was free from clicks, crackles, scratch noise, and other background noise--without any appreciable loss of high end. Highly recommended if you have the cash. RX 2 is also available on the Mac.

Where many noise reduction programs leave the processed audio sounding flat and lifeless, Izotope RX somehow manages to remove the noise and defects while leaving the original material largely unscathed. There's fully automated processing, plus a spectrographic display and unique tools that allow fine manual editing. Izotope RX is expensive, but the best usually is. The program is currently on version 6.
- Outstanding noise and artifact reduction/removal
- Easy interface and workflow
