Hallo!
What about take sample of "clean noise"
(usually on beginning of
recorded track) and use some phase cancellation trick to add sampled
noise in opposite phase.
No, because noise has random phase, if you are speaking from
non-periodic noise ...
But a similar idea is used by many spectral-based noise reduction
techniques:
they take a short noise print and then try to remove this constant noise
from all other signals, so that just the signal without the noise remains.
