Noise Removal (and other effects) Advice

[kwartz]

That brings up another discussion point. How are you measuring your work?

After running through my effects, including Noise Removal, I highlight a section that is just background noise, then go to Analyze > Contrast, and click a Measure Selection button. Maybe that's not the correct way?

Thanks.

That's one way. We get immediately into the different ways to measure noise. If you're in the US, you are no doubt familiar with OSHA which puts those orange and white warnings on the ladders [You could fall and terminate your family tree]. They measure noise A weight which can give a significantly different reading than C weighing or Z. I think the Audacity tools measures Z. I could be corrected.

A takes into account the difference between pleasant distant thunder and Infant Screaming on a Jet.

There is a USB Microphone digital failure which illustrates this beautifully. I call it Frying Mosquitoes and it's not very loud, but it's right at that pitch that makes homicide attractive.

There are differing opinions on what ACX uses.

Not to go all crazy on you, but if ACX compliance was one single, simple thing, it would make everyone's life a lot easier.

Use OSHA standards. Does extended exposure your show contribute to damage in unborn children?

OK, back on topic...

I think you overdid the patched clip.

Not by a lot, but yes I agree, a bit overcooked.

I was trying to hit the maximum -60db noise floor,

You've gone way below it, but I can see why you think you haven't.

After running through my effects, including Noise Removal, I highlight a section that is just background noise, then go to Analyze > Contrast,

That's going to give you a figure that is a lot higher than it really is, because of those thumps and clicks. If you miss the thumps and clicks, the rest measures at about -86 dB.

Ok, thanks, good to know.
