I've been playing around with various freeware and low cost audio apps- 
trying to find the best solution for cleaning up some video with 
sub-standard audio. What I have is video (shot by someone else) where 
the audio seems to have been recorded at too low a level. When I turn 
up the volume high enough to hear the music, I also clearly hear tape 
hiss.

Amadeus' "denoise" operation will remove the hiss, but it also removes 
part of the music and spoken voice in the softer areas. I found that I 
can cure the problems with Audio Hijack Pro by running the audio 
through the ten-band EQ and Double Gain effects.

I haven't tried it yet, but it seems to me that, if I record the Audio 
Hijack output as an AIFF file and try to replace the bad audio with the 
improved version, I'm going to have a devil of a time syncing the audio 
with the video. Your message said you used Audio Hijack to "tweak the 
sound BEFORE capturing." That would definitely solve my problem, but I 
can't figure out how you accomplish the "before" part.
