Yup, there are various alternatives for noise removal that are more effective than I found DNOISE to be. Although I think denoise works good on many things. But it takes a scientific effort.
I have the WAVES plugins for noise... and it DOES work wonders... but not so hot on complex noises like you find on 78 records.
For that, I recommend DC Seven
http://www.enhancedaudio.com/dc_seven.htm
If their demos are REAL, they have found the Holy Grail
in dnoising. Of course, their program is about $1800.
But it appears to work miracles... literally.
They've got some OTHER software too... and all I can say is,
if I could make money in this business, I'd own all of their
software. But alas... this business is getting more and more
rediculous by the day. After 37 years... I'm trying to figure
out what else could I do for a living. All these schools are
graduating "audio engineers" by the truck load... and by the
time they can't find work, and then start wacking down the
rates, thus reducing the marketplace to non-profit
status... I have to ask what's the point anymore?
CD sales are less and less... and piracy is more
rampant daily. The public now thinks they're entitled to FREE
music and movies. So... where does that leave us?
BROKE... POOR and unemployed.
Hate to dump negative vibes here... but...
we're all in a pickle.
