Noise reduction for Mac music files?, Want to reduce surface noise on 78s. Options

I've had good success transferring cassette and vinyl recordings to iTunes using a freeware program called 'Coaster.'  But before burning CD's of my noisy 78 RPM recordings I'd like to find some program that features equalization and noise reduction.  I know about Spin Doctor, but that requires purchase of Toast and moreover it does not have 'real-time preview,' which permits you to listen while you adjust the settings.  There are 4 programs that I'm aware of with this feature, but I believe all are for Windows machines: Sound Laundry, DCART, Wave Repair, and CoolEdit (just recently added the preview feature).  Does any one know of any comparable programs for the Macintosh?  (I'm not an audiophile--just looking for something relatively simple and inexpensive.)

other than using a VST app and plug system as mentioned above or using PT with Broadband Noise Reduction RTAS plug, I don't know of any app that works on mac and gives you real time preview of the sound input with noise reduction. You may even want to consider just getting the sound into the mac and then using another app to do your noise reduction on the recorded files. May take longer but may be cheaper in the long run.

I realize that not everyone has lots of money to spend on apps and equipment but sometimes when you are really specific about how you want something done on a mac... you really are going to have to buy some goodies, or find a friend with a mac and lots of apps, or cover one eye with a hand (and walk with a peg leg) and voyage out on to the deeper darker corners of the net and break that modem in with some hot d/l's. Good place to look is within the hotline servers. App can be found at http://www.hotlinesw.com/
