Recording Hiss Removal? Can anyone help?
Anybody good at removing recording hiss? I've had a go with the noise reduction plug in that comes with Audacity and am getting nowhere.
I'm trying to remove hiss from a demo, it's just a few tracks of acoustic stuff. Can anyone help me? I'd be very happy to pay something or in beers or the like.

Re: Rocording Hiss Removal? Can anyone help?
See if audacity has a parametric eq, one with gain, freq and Q, then try cranking the gain and Q up all the way, and slide the freq around until the hiss gets real nasty...then turn the gain all the way down...it won't take away all the hiss, but it might make it a little more promanent...and if the Q is cranked, it shouldn't mess up the tone of your recording!
Otherwise, you'll have to try a gate, or probably both the gate and the eq!

Yeah, nah, I know that. I was wondering if someone was willing to swap that for beers or whatever and save me the trial and error phase, which I'm finding boring and time consuming.aliasceiza wrote:See if audacity has a parametric eq, one with gain, freq and Q, then try cranking the gain and Q up all the way, and slide the freq around until the hiss gets real nasty...then turn the gain all the way down...it won't take away all the hiss, but it might make it a little more promanent...and if the Q is cranked, it shouldn't mess up the tone of your recording!

Do you have a dropbox or some such for sending big files?

For a one off, download the demo of Izotope RX. The denoiser is great and much less destructive than notch eqing. Easy to use too.

Nah, I'd rather something I can learn or whatever and use on a regular basis not just within ten days.bbrunskill wrote:^^^^
This.
$1K (or $400) sounds a bit steep for regular use. I'd rather buy better recording gear with that money.
Thanks for the idea, though.

I just bought a plug in that adds hiss!

Re: Recording Hiss Removal? Can anyone help?
Noise reduction is really tricky- hiss is actually quite broadband and therefore difficult to EQ out. You could try applying a high-frequency shelving EQ cutting at about 6kHz. This will have the effect of pushing the noise 'back' but won't remove it altogether.
I could possibly clean it up for you, Vince. I'm slammed until about Tuesday though.

I vaguely remember you talking about cutting frequencies at 2K but it doesn't seem to make much difference. All that seems to happen is I get hiss at different pitches.
If you want to have a tilt at it, that would be fantastic (I don't mind waiting) as long as you tell me what you did afterward.

Re: Recording Hiss Removal? Can anyone help?
That's what I mean by hiss being broadband- it covers a wide frequency band. If you cut a specific frequency, it still leaves all the others. A shelving EQ will effectively lower everything above a certain frequency point and a Low Pass Filter (LPF) will cut everything above that frequency (ie filtering it out). The best way to use either is to sweep the frequency until you find the right balance between reducing the hiss and affecting the instrument you've recorded.Vince wrote:benderissimo wrote:Noise reduction is really tricky- hiss is actually quite broadband and therefore difficult to EQ out.

FWIW, standard NR procedure is: select a bit of the recording where you're not playing (ie where all you can hear is the hiss you want to remove), use the 'learn', 'train' or 'profile' function in the NR plug-in (this allows the plug-in to distinguish what is noise and what is not), then select the entire recording and tweak the amount of reduction so that it sounds as natural as possible.

Nope, I was just recording through the laptop (it's acoustic music so I'd rather not plug directly into it).willow13 wrote:what caused the hiss in the first place?? is it an old tape or something
I've tried using a mike but the adapter wasn't fitting correctly. But even when I've used a mike and a pre amp and so on, I still get a lot of hiss.
