<<Interesting... the systems I've used begin with a noise print, and
then the paramaters (threshold, noise reduction, etc.) can be
adjusted manually based on that noise print. Is that what Bias
Soundsoap Pro does? (I get the impression from your message that its
noise printing is automatic and offers no user intervention...
perhaps I misread?)>>
Right, that's how SoundSoap Pro works, too. You hit the "Learn Noise"
button & it comes up with a 'curve' which you can get in & work on
manually afterwards band by band, to fine tune the process. The user
interface is basically that of a graphic EQ, with 2 faders per band.
One for threshold & one for amount of noise reduction. I just find
that the 'learned noise' print version is always too heavy handed & I
get better (to my ears) results by zeroing all the faders & manually
tuning only the few bands I feel are needed.
Last year I purchased iZotope's RX noise reduction software & have
found it a tool I can't use. It's not a real time process. It takes a
noise print and you have some control over amount of noise reduction.
You have to wait for it to render the file to hear the results, you
have no control over frequency weighting, & in all cases I found the
'one size fits all' approach they present the user with provided
results which were either insufficiently noise reduced, or which
degraded the audio by doing too much. I really find I need the
individual control of multiple frequency bands to obtain noise
reduction results I can live with. This is for my CD mastering
business, so the quality demands are critical.
<<When adjusting parameters, by the way, I always monitor the signal
being removed to ensure that none of the signal I want to keep is
being removed. This usually allows me to get an optimum level of
noise reduction that does not compromise the desired signal itself.>>
SoundSoap Pro does this too, with the "Noise Only" button. It's
crucial to check this regularly to make sure it's only taking
unwanted noise & none of the desired signal.
I'll point out again that SoundSoap Pro is vastly different from
SoundSoap, which IMO is basically useless for professional work.
