[PlanetCCRMA] Need to remove hiss from digitized tape recording

[Brian Jarrett]

First off let me say that this collection of software is awesome!  It's so awesome, in fact, that I'm discovering new things every day.

If I had my wish there would be some sort of documentation about what software to use for what tasks BECAUSE there is so much out there.

Since such documentation doesn't exist (that I've seen anyway) I'll post my question here:

I would like to remove (or lessen) some of the background hiss that I have from a recording I made from a tape player to through my sound card.  I haven't tried using a better cassette deck with something like Dolby Noise Reduction to see if that helps, but I was also wondering if there were some software packages that might be able to help me out.

Are there "filters" or effects that would do the same thing as Dolby NR?  Is there something that could help me isolate and remove the hiss?

Any ideas and hints would be greatly appreciated.

Thanks,
Brian
