Here's a dos cetanvos response - I find SoundSoap can be destructive
if used in amounts that are effective - inother words, close to useless.
I have Izotope RX and find it can be remarkably effective, but again
as with all noise redution, moderation is essential. You can reduce
noise only up to the point where it begins to detract from the
desired sounds. And often multiple gentle passes will be more
effective than one severe application. Almost always you want to back
off from the initial settings, in my experience.
I just used RX on a beautiful live recording I did last week to
remove the sound of the hall's lights humming and the AC whooshing.
It can be stunningly effective - in moderation!
Knowing where to stop is part of the art and the vital part of good
ears in the entire process. It's a bit like knowing when the playback
is "good enough" and when it is just showing the warts in the old
I'd rather hear some surfece noise than a dull overprocessed transfer!
