My mother and her sisters made a cassette for my daughter with some songs on it, and unfortunately, they were no sound engineers among them. The recording level was very low because they were nowhere near the crappy little mic, and there's lots of hiss since I had to normalize the hell out of it.
I have it sucked down to my hard drive, but I'm hoping for something to post-process it and suppress the bad tape hiss. I've heard that CD Spin Doctor does this, but I've never used it. (I have Toast 5Ti, but I can't find that app, nor can I find a downloadable update from Roxio.)
Are there any other alternatives? I'd be looking for a free one, or somewhere I can get the OSX version of Spin Doctor that goes with my Toast Ti.
