This program does have a bit of a high price. And if you are a music afficiando, you will probably prefer the sound a real record scratch to this. But if you cannot afford a turntable, new needles every two weeks, and hundreds of records - or if you just can't scratch - this program is a great alternative. It lets you scratch any AIFF files (which iTunes can make from its library), so effectively you can scratch almost any sound file on your computer. There is no real learning curve. After a few seconds, I learned what each notation meant and how to manipulate it effectively.

If you want to add some scratches into a sound file, and don't plan on doing it for a profession, then this is a good program. For the rest of us, or those strapped for cash, might wanna move on.
