I say:

Noise == <3

Some people remove noise.
Others make a distortion plugin.

noise == <3, so true.

yet, hardware-buzzing coming from the vic with only one goal in mind: making the recording sound fucked up != <3.

i'd prefer to do it the software way, yet i'm not quite the best among the mastering-bunch. is there any surefire way to get rid of *any* bastard-sounds without hearable loss of the intended sound?

@pan engmann:
you mean, the software way? no. if signal and noise share the same frequency, there is little you can do about it. (otherwise, it should be easy enough.) noise profile based method fails miserably in this case, you'll be better off with manual eq'ing the noise out, using a few thin notch filters.
the best way to get around the noise being 'under' the signal is to fatten up the arrangement, in particular: introducing more tracks operating in required frequency area. for example, a 8-14kHz hiss on vocals can be easily 'patched' by glossy, sharp hihat.
of course, there are professional mastering tools that make the process a breeze, more or less. however i doubt if you can afford them.
care to correct me, someone? i'd be more than glad.

Software way: I usually use Goldwave for this. The only thing that is required is a background-noise sample. The result is usually extremely good (good enough for audio-cds).

Here two examples. It removes the most noise, but not everything.
Anyway, it's a good solution instead of hacking the hardware. :)

I think it's common knowledge, but just in case: disable VIC while playing, it'll get rid of much noise. The MMC64 browser is capable of that (just press space).

Noise removal postprocessing (I did it with Audacity) always introduced some kind of artefacts for me.

especially when it comes to the sid, using postprocessing isnt very effective. better eliminate the noise by other means and dont record it in the first place.

is it possible to disable the VIC without MMC64? if so, how to do it?
