How To Remove Tape Hiss

Greetings,
Very happy MacBook Pro user! Can I use GarageBand to remove tape hiss from an old recording? I have successfully transferred the recording from a good tape deck to GarageBand via a good firewire audio interface.

I've seen suggestion to use various audio editor programs for this purpose. I'm wondering, is GarageBand up to the job?

Thanks in advance.
