Getting rid of background noise

I've got some interviews that were done in a factory, and there is a constant hum of the factory machines in the background. I've tried a number of different audio filters in FCP, but I can't get it right.
Any suggestions?
Thanks,
Eric

Aside from the previous helpful suggestions:
Expander Noise Gate Filter can be helpful for this. Try the threshold at about -15 and the ratio at 1.5
Adjust the threshold and see what happens. I wouldn't adjust the ratio that much.

Niel,
Thanks for your suggestion about using RCDefaultApp. I am hesitating to do this because it seems like I'd be installing still another piece of software to fix the original mistake---downloading Reader.
About 20 years ago I maintained---with considerable handholding---UNIX systems of various sorts. Can you suggest how I might find the plist that seems to require changing?
BTW, Preview is called whenever I open some random .pdf file. The problem appears when I want to get a file from the web. If the site permits a "download" I can get the file, but if I want to "view and print" the file, the evil dark-grey Adobe screen appears with the whirling black ball. Then Safari quits. I'm wondering if the reference to Reader is in a "cookie" sent from the website, when I first was installing Reader. Is this possible?

How to get rid of background noises?

what would be the best way to edit a track to get rid of background noises like a guitar bleeding into the vocal mic?

Three things to try:
1) Insert the Noise Gate plug-in. Use judiciously, or you'll truncate the vocal (breaths, lip noise etc).
2) Use 'Strip Silence' on your vocal track (Audio Window)
3) Double-click on vocal track (Sample Editor) and using the change gain function, reduce the spilled noise in sections that are bothering you.
Which one works best for you depending on your track, but if the guitar bleed is too loud +while the vocal is present+, there's not really a magic filter to get rid of it.

How do I get rid of background noise?

Trying to get rid of background music from a speech given. The speech was infront of a mic so that audio is strong. Just need to get rid of the music in the background. Any suggestions?

FYI: Much of noise reduction depends on what "type" of noise you are trying to eradicate. E.g., in a sample piece of footage involving an interview with a lady in a cafe, there was a busy street outside.. just at the point in a critical line in her speech you could hear a break squeal in the background, you know, that high pitch squeal you hear from disc brakes from a vehicle!
Interesting bit! > What I learnt was that I could visualize the squeal frequency in the spectrum analyser.. it was very clear to see the offending noise.. then to eradicate it (and ONLY the break sequel) Using the mouse pointer I could simply select the spectrum print of the actual noise and press Delete! Amazing! Very quick but most importantly, absolutely no effect of the dynamics of the surrounding audio. Very Cool!

Help to get rid of background noise in GB3 when recording voice on Sony mic

I am recording my voice into GB3 using a Sony ECM-MS907 condenser microphone connected to the line-in input on my iMac (core duo 20"). I use basic vocals with no effects.
My voice records fine but there is a background noise underneath which I can't seem to get rid of. It is also present if I use the built in microphone. I don't think it is room noise as it is pretty constant throughout.
I have added a backing track which helps to mask it but this is not really satisfactory.
Any ideas how I can record without this apparent interference?

What version of Premiere Elements are you using and on what computer operating system is it running?
Classically USB microphones do not work with Premiere Elements (any version) for use with its Narration Tool. Have you found otherwise?
Where is the noise - in narration clips produced by the Narration Tool or from imported audio files added to numbered Audio Tracks and/or soundtrack?
From what you wrote, it appears that the audio noises are confined to the narration being produced with your microphone and Premiere Elements Narration Tool. Is that correct?
Under fx Effects there are audio effects that you can explore to reduce noise. See Reference Effects Adobe document for a description of the fx Effects audio effects.

If you use the same microphone and create your narration in Audacity and import that narration into a Premiere Elements project, do you get noise in your narration?

Besides making sure that your microphone is compatible with Premiere Elements, have you evaluated your narration recording techniques...how close are you to the microphone, room noise level while recording, etc.

How to get rid of background noise when recording voice on iphone 5 ?

every time i record a voice over i hear wierd background noise can someone tell me how to get rid of it im using my headphones to record btw

Go to System Preferences / Sound and click on the Input button. You should see two items listed in the device menu: the Internal Microphone and Line In. (There may be others if you also are using your USB or Firewire ports for input devices.)
Select Internal Microphone and adjust the Input Volume control to the far left (minimum). This will mute the computer's internal microphone.
Then select the Line-In (or other device) and adjust the input level as needed to make your recording.
Good luck.

Getting rid of background noise when recording cassettes

How do I get rid of the hissing background noise when I transfer cassettes into GB?

Thanks - this is totally new to me. What sort of software do I need to clean up the noise after the fact? I'm dealing with old cassettes and a cassette player with no dolby option.
there's a bunch of applications that will clean up or "restore" noisy audio, and they range a lot in price and features. Here's a few options:
Bias makes Soundsoap 2 (around $100) and Soundsoap Pro (around $550). Bias makes some great audio software, so Soundsoap 2 might be more than adequate.

If you think you might want to use Roxio's Toast 10 Titanium Pro (around $115), it comes with a version of Soundsoap included. As long as you don't need the features of a dedicated noise removal application, it's a pretty good deal:

How do I get rid of background noise when recording a slideshow??

Im trying to record a slideshow for keynote with music soundtrack coming in time with the clicks, but even when I plug a mike cable into what looks like the mike socket, i still hear background noise such as me tapping the key board...
any tips? Is there a way of turning the microphone off completely??

Ios7 update audio is hissing and static. Please help me get rid of this noise so I may enjoy my audio on my iPad

Ever since the ios7 update my audio is hissing and has static. Please help me get rid of this noise so I may enjoy my audio on my iPad

Just for the record, this is what I wrote to Apple feedback:
(If anyone really knows what the problem is, please let us know.)
Apple iPad mini. Re: Hiss
Hi. I am one of the very unhappy people who can't use the iPad for recording since getting ios7. The apple forum is replete with stories like mine: ios6 recording was quiet - ios7 is noisy. I have tried every suggestion. Why won't anybody at apple tell us what the problem is? I have been using macs since 1986. All I want to do is record my songs on my iPad. Unfortunately for me, I recently brought my iPad-mini refurbished so there is no warranty. If I had bought it new I would be at the Genius Bar until I got the problem fixed. Did I mention how unhappy I am? Here are the specs: 1st gen iPad mini running ios7. Recording onto Multitrack DAW with a Samson Go mic to a 30-pin USB camera adapter, into an apple brand lightening adapter into iPad mini. Everything works fine except for the HISS.

Is there any way I can get rid of the noise my iPod makes when I plug it in to charge without turning the volume of the whole IPod (4th Generation) down?

I have a 4th generation IPod touch. Today I downloaded the new iOS 6.0.1 and I have a question. Is there any way I can get rid of the noise when I plug it in to charge? I had it set that way before, and I can't seem to figure out how I did it. I found when I turned down the over all volume it gets rid of it, but I don't want to change the over all volume. Thanks so much for you help and Happy Holidays.

If it has NEVER been jailbroke, here are some standard repair procedures:
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore (or it doesn't help), go into Recovery Mode per the instructions here. You WILL lose all of your data (game scores, etc,) but, for the most part, you can redownload apps and music without being charged again. Also, read this.

How to get rid of wind noise on the audio track

I am sure there must be a method to get rid of wind noise on the audio track. Can someone tell me what the best filter is for this purpose as I shoot mostly outdoors and even with a sock covered mike I pick up the wind noise? I have FCS and therefore Soundtrack Pro. Are there filters in the audio filters section of FCP or must I go to STP? Thanks in advance!

I shoot mostly outdoors too, and it gets pretty windy where I live!
> I shoot mostly

I hope you mean you have a Rycote "Softie" or something similar protecting your mic . . ?
If so, you should be able to shoot in quite a high wind without any "wind noise" - but of course, even if your "sock" is correctly fitted and working well, you'll pick up the sound of the wind (different thing altogether).
If you have the right gear and are experiencing the buffeting sound you get with an unprotected mic, then I suspect there are gaps somewhere - so tape them up!
Either way, for removing unwanted sound, I know of no tool like the Linear Phase EQ filter in STP. Like everything new, it takes a little time to learn but it's very well worth it. With practice, you can almost slice out much unwanted sound like a knife.
I'm not sure why you don't want to use STP - it opened up a whole new world to me - and it's easier to learn than FCP IMHO.

Getting rid of "clip" noise

I've got a bass track I'm editing, but no matter where I cut it at the end, it still has an obvious clip nose like you can tell it was cut. I'd use the volume automation, but it'll change the whole volume of my bass track. So my question is what's the easiest way to get rid of the noise or hide it? Thanks

The real thing is to find what exactly is causing the issue as opposed to trying to use a "band aid" to fix it.
It could be a bad cable, some kind of ground loop, a severe input impedance mismatch.
These kind of audio issues sometimes require some exploration, it could be as simple as a gain staging issue...etc.
Wish I could be of more help, but not actually having hands on, it's difficult.
Have you tried a DI to step the impedance down to closer to a mic level?
It's worth a try if it's an option, as this will greatly change the input level, not volumewise, more of an electrical interface thing.
I hope some of this might help you...and yes, gating will change the sustain of everything on the track. It would be most effective during the silent parts.
Best of luck, I would try other ideas with you if you are willing to wait a little for any reply, as I have been limited on line time. 18 hr days kind if have a way of doing that to you.
All the best

Getting rid of Fan Noise

I made a video on how to make Greeting cards. In the background you can hear the background noise of the fans for the lights. I tried to use the Hum remover filter and it doesn't seem to help it any at all.
If you go to www.GreetingCardWorks.com/clips.html you can hear the background noise after the title clip. I am taking FCP Studio 2.0 in College and so far were working on how to make titles.
Clark

In my experience, fan or generator noise peaks at two points - usually in the very high range, which can be fixed by applying a low pass filter. Finding the lower hum will take some searching - you can use the 2 band eq in FCP for this. turn the gain way down with a very narrow bandwidth and move the frequency around until you notch out the hum. You probably will not be able to get rid of it completely, but definitely make it less annoying.
