I guess it's a no.
I'll stick with Goldwave though because of this post:

I tried Audacity for analog tape hiss removal and it works fairly well. I've only used it on WAV files I don't know in what format your Dazzle device captures.
Audacity uses a two step process to remove the noise, first you select a segment of just noise, then you select the segment that needs to be cleaned (probably the whole audio file). When you get to step two of Audacity's noise removal procedure you need to indicate how much noise you want to remove, try very low settings, the default medium setting will probably really distort your audio. After filtering with audacity I had some left over very quiet background noise that sounds a little like a child's keyboard.
I you have Nero 6 suite, the full edition, it's wave editor has a similiar feature that seems to work a little better than audacity's.
I've been using Goldwave but it's shareware. (about $45 I think) I think it works the best of the three with no remaining background noise. Try it with the default setting's except set the FFT size to it's maximum value - 14. Good Luck. Mike.
