Noisy Samples, What to Do, What to Do...

Noisy Samples, What to Do, What to Do...

2008-01-17 by Niall Munnelly

I have a few samples in the MD that could use a little
cleaning.  Ideally, I'd like to ensure that I'll have no
artifacts in any of my samples in the future, so what would
be the best way to do so?  Lower the volume and truncate any
fairly quiet bits in my 16+ bit samples?  Dither my samples
to 12 bit and ensure that they're clean in that format
before loading them onto the MD?  If so, what Windows app
would you recommend {no Mac here in Ireland, and not much
software on me, either}?

Cheers.

I guess moving them to 12-bit prior seems like a good idea. I don't 
think lowering the volume should have any influence (unless there's 
something .. huu .. buggy in the UW). Audacity is free and should do 
that without too much hassle.

Id concure, that Audacity would be the way to go.  Lowering the volumn
shouldnt have any effect.  the MD is probably just has either a cheap
algorithm for cutting down to 12 bit, or it just uses bit truncation
to do so which will sound messy.

You could try REAPER too and use it's FFT EQ plugin as noise reduction

Kind of hard to offer an approach without knowing more about the
nature of these artifacts you're hearing.  Ideally I'd say go into a
wave editor and try and draw them out at the sample level, but maybe
there's too many of them for that, or you're talking about some type
of rumble, etc.  In that case EQing them in advance might work better.

Not sure that bit reducing to 12bit first will really help that much,
though it's worth a try.  Personally all my samples are 24bit anyway,
so I just leave them at that bit depth when I import them into C6, and
I've never noticed any issues with extra noise being added to them
after they get into the MD.  I mean, yeah they sound different cause
not they're 12bit, but nothin out of the ordinary keeping that in
mind.

If you want to send me a couple of the sample, I can take quick listen though.

Cool, but It's again a soft only for microsoft users ...
