i know i asked you guys about this topic andf i know how to use it but im just asking for some "tricks"on how to make the best use of it…is it best to keep the sliders to the right or the left?..if i slide them more to the right it makes the files lower to much to the right and i hear no improvemets to the file…any suggestions?thanks
My usual settings are usually in the region of:
Make sure that you use a good “Noise Profile” - it should ideally be a couple of seconds or more and contain only noise (no music).
If the noise is quiet then amplify the noise, e.g. normalise it, before sampling a bit for the “noise profile”.
This will make the noise loud enough for you to hear clearly so you can select a bit which is typical noise and doesn’t contain any atypical sounds,
(e,g, faint background sounds of voices or vehicles, or glitches).
Use the least amount of noise reduction, (lowest number), to produce an acceptable result to your ear. Better too little than too much in my opinion.
The amount value is pretty simple, more effect as you go higher. The lower, the better. It could be argued that you should leave a little noise in the background, so the show doesn’t sound like it’s in a black hole. Also, once you do produce a “velvety black” background, it’s much harder to adjust the other values and it’s very much easier to overdo it.
The Frequency Smoothing is pretty important of the three. Too low and you get bubbly, gargly sound, too high and you get noise tails after each word.
I’ve never sound a need for the delay value.
the folkes who develipe this stuff should develope a noise reducer that is automatic and easier to use…just my opinion…
If they could, I’m sure they would, but noise reduction is not an easy thing to do - is depends very much on the type of noise, and the type of material that is being processed. The manual adjustments are available to allow the user to tweak the effect for best results. If you don’t want to tweak and are happy with “generic” settings, just use the default values.
where r the default setting for the noise reduction?
There is a program called SoundSoap, whose later versions were quite good at “cleaning up” bad sound, but they insisted that the only way to get terrific noise reduction was to be really careful about getting the profile of bad sound without any music in it. The program, (Audacity, too) would try to subtract them.
It would try to figure out what the “noise” was without that, but the results were usually pretty awful.
Then there’s the problem of “Noise.” No shortage of people trying to get rid of dog barking or jet going over. Those aren’t noise. Those are performers.
There have been people who were able to separate instruments in a mixed performance by skillful manipulation of Noise Reduction. Getting rid of air conditioner rumble isn’t the only thing it does.
my media of coise is 78s and lps…some 45a…i have some 78s from around 1921 that nothing will clean up…even nero.once a 78s is "gone"nothing will fix it up.in the days where 78s were common they used these steele needles before they were called stylus…an average 78 cost around 35 cents.it was only good for about 4 plays before
it was ruined…then we got them today and have these issues with them…lets face it mr edisons shallack records were not durable…
Groove distortion isn’t noise and much of the rest of the trash isn’t either. Noise is a single sound that stays constant through the course of the whole performance. It’s good if it doesn’t share the characteristics of the performers, too. That’s why white noise or microphone hiss is so hard to remove.
Have you tried the Click Removal tool? That’s more like the damage you actually have. I admit being curious what would happen with the Clip Fix tool. You may be able to get rid of some of the distortion with that.
how do i download that?it seems to be a plug in…
Both of them seem to have arrived with my Audacity 1.3.7. Click Removal is a regular tool, but Clip Fix is an add-on at the bottom of the pile. I’ve never downloaded Clip Fix, so that’s the only way it could have gotten here.
