Remove background noise from imovie '09

Can I remove background noise from imovie '09 more than one clip at a time?

Ya you got it rightly I read a guide here http://www.kenstone.net/fcphomepage/basic_audio_filtertutoria.html
so I am aware of basic things at least.Like you gave an example of Main Parameter in your previous reply similarly I feel if some where I can get these parameters in Filter what do they do that may help.

Can Logic plug ins remove background noise from interview?

Can Logic plug ins remove background noise from interview?
A friend with an important interview recorded in noisy conditions has asked me to help remove background noise - never done this technically.
Is there a Logic or third party plug in that would could remove background noise from a spoken word interview? Have tried EQ which improves the sound slightly but not a solution.
Anyone with specialised knowledge of this sound editing operation?
cheers

There are several 3rd party denoisers, they mostly work by first 'learning' the noise footprint of the audio, for which it is best to record a few seconds of silence (with an open mic).
These will all do a decent to excellent (it all depends on the source material) job:

Addit:
Is it that background noise (traffic, talking etc) drowns out the words? Then you'd probably have more luck with (radical) eq-ing and/or notch filtering to find the most dominant frequency range of the speaker in relation to the background noise.
As an interviewer myself I will point out that even with a small disctaphone you need to have some awareness of how the microphone picks up things. As soon as you nead to lean towards whoever you're talking to, just to make sure you're audible, the dictaphone on the table is probably recording mainly ambient noise, the interview being part of that. This is especially a problem when interviewing in a busy public space.

Removing background "noise" from an interview recording

Hello!
I was wondering if it was possible on Soundtrack Pro to remove continuous background "noise" from a recorded interview? An example would be someone clicking a pen or a tapping his foot during the duration of the interview. Any advice would be extremely helpful.
Thanks so much!
Ted

It can, but what you are describing are not continuous, but points of sound. Continuous refers more to hums and vibrations, things like air conditioner noise or the sound of traffic. That said you can still give it a try. You can also try running the click and pop filter and see what you get.
Regarding these point sources I have better luck removing them with Adobe's Soundbooth. Their cascading frequency display allows you to draw irregular shapes around sounds like these and then extract them without disturbing the other sounds around them.
Take a look at the manual.
Good luck

Removing background noise from captured clip

I wanted to edit an audio which was captured with Video also it contains some background noise.Which filter should I try for this in FCP.

I read that tutorial it is nice but I have only Final Cut Pro 4.5 HD not the SoundTrack Pro is there no option in FCP for editing audio I do not have much to edit I have to remove sound of a crow and in another video captured audio is having sound very low without increasing volume it is not possible to listen to it.
So for this any thing that can be done within FCP.
I have only Soundtrack 1.2 which is not professional version.

Advice with removing background noise from recording

I made a recording but there is an extrotor fan noise going in the background which is really off putting, is there a way to edit this?

Hi Sarah, and welcome to the forum!
Regarding your question, any solution,even the most sophisticated ProTools-based one, uses some sort of comb filtering/eq to remove those unwanted frequencies. This means that your sound will suffer to a certain extent because the frequencies occupied by the fan noise overlap with instruments/voice in your recording, and when you remove the frequencies associated with the fan, you also remove part of your music.
Having said that, you can try the following and see if it works for you:
Choose a parametric eq plug-in (you didn't mention which s/ware you're using, but most programs that can record do also have eq, so I'm assuming you have one) and boost generously one of the frequencies below 1000Hz and sweep it across the frequencies field. You should find a spot where the fan noise is most prominent. Now narrow the eq curve and redo your sweep - same procedure than before. Then do it again with - yet again an even narrower eq curve. Your goal here is to zoom as much as possible on the offending fan frequencies. Once you have found them this way, cut around 2-4db. You will remove sound elements in your music as well as fan noise, but that's as good as you'll get.
What you can also do is try to use a mistake creatively. Eq you track radically, experiment. Use the fan noise as if it were another instrument. "Play" it. Don't be afraid to mangle the recording, push the envelope. Who knows, something interesting might come out. I always liked turning a disadvantage into an advantage
All else failing, you just might have to re-record it, and if you do, take a chance, do something different; don't try to emulate what you had before because it will only hinder you. Try something new.
Hope this helps a little.

Removing background noise from photographs

Hello -
I have a handful of photographs that contain background annoyances such as basketball hoops, doors, etc. I am new to Elements 7 and was wondering if there was a simply way to address this issue. Again, I am a newby and not yet thoroughly famliar with the Elements tool set. I've provided an example of what I'm attempting to correct.
If I could get a step-by-step formula, that would be great!
Thank you.

There are many ways to remove unwanted items and this is a whole topic in itself. However since your example has so many things going on in the background and since it is such a great group shot I tried a studio portrait look:
Here's how:
1. Add a blank layer above the picture.
2. Set the Foreground/Background colors (color chips at bootom of toolbar) to light and dark shades of brown.
3. Apply the Clouds filter to this layer to get the portrait-like background. If the cloud effect looks to harsh it can be softened with a Gaussian Blur.
4. Add a Levels adjustment layer above the picture layer but do not make any adjustments, Just click OK.
5. Group the background layer and Levels layer.
6. At this point all you see is the background. Now actvivate the Levels layer and fill with black. This restores the picture.
7. Set the Foreground/Background colors to their white/black defaults.
8. Use the Brush tool with a hard brush and paint with white to reveal the background. If you paint to far and cover one of the persons, switch to black and paint to restore him/her. While painting you can type "X" to toggle between the black and white. Note that for the subject's hair the results looked more natural using a soft brush.
9. I also used the Clone tool to remove some flash spots on the faces and glasses.
10. Finally cropped to a 8x10 proportion.

Removing background noise on only one of two tracks

Hello and thank you in advanced for your help. I am new to STP but well versed in FCP. I've recently discovered the wonderful feature of removing background noise in my video clips.
I'm having trouble with one instance though: I have footage shot with a microphone into only one channel of the camera. In FCP, I highlight that channel of audio and "send to" STP just as I have other clips. This time, however, no matter what I seem to try, both left and right audio channels show up in STP and I can't seem to separate them in order to remove the hiss from only one channel.
If I proceed as normal and select a portion of the hiss to set as "noise print" I can only select both tracks, not only the track I want. Probably a matter of a simple button, but I don't know STP well enough and the manual was no help. Anyway, continuing with the process to "reduce noise" and adjusting the parameters I hear almost no difference when turning the filter on and off.
I'm not sure if I've explained my scenario the best, but I'd appreciate some assistance.
Thank you!
Eric P

Eric,
Make sure the stereo file is open in the Editor as an Audio file. Click inside the editor window area and move your mouse pointer up to the top of the left channel's window border. If done correctly a tiny "L" will appear. This lets you know you can select the left channel, or portions of it.
Do the same for the right channel. However instead of moving the mouse pointer to the top area of the window, move it to the bottom of the Right channel's pane. Look for the tiny 'R."
Proceed as normal: Set a noise print, adjust parameters, and process. You'll find only the selected channel will be processed.

How do I eliminate background noise from a recording?

I loaded an audiotape from a cassette to my MacBook. There is too much background noise and I don't know how to get rid of it. Is it possible? Thanks, Miriam

One option is to use the (free) Audacity. Just load the mp3 or aiff and follow the instructions to construct a noise profile and then get rid of the background noise. Once that is done, one can reimport the file into iMovie, if you choose.
Export the file from iMovie 09 as mp3 or aiff file. Import into Audacity. Get rid of the noise. Export from Audacity as a mp3 or aiff file, and use that as you like.
To find out how to use Audacity, I recommend checking out the fine tutorials on YouTube.

Removing background noise

Hi All
I am new to imovie and took video on my iphone 4s and converted in imovie added music and i thought great went to put on you tube and facebook and couldn't because of the music and copyright issues
i can take the music off of the video but then i get wind noise (the video is me on my trike) how do i get rid of wind noise in imovie 11
thanks in advance
eon

Trouble is, in my experience, the person who yells (or the dog that barks or the car horn that honks) usually does it right in the middle of somebody's dialogue, and there's no way to untangle the noise from the words. You end up losing the word or a syllable, and then have to resort to a voiceover, which usually doesn't match well for one reason or another, often because the ambiance or surrounding sound is different. If possible, you have to get the speaker in the same place he originally recorded in, to repeat the word, or better, the whole sentence for the microphone.
But yes, an isolated noise is easily removed with the pen tool in an enlarged view of the audio track. In fact I can mute overly loud P and S sound in speech just by drawing down the audio line at exactly the spike in the audio waveform.

How can I get the background music from iMovie trailer, "Romance"to be used in another imovie?

Is there any way to download the background music from the iMovie trailer template "Romance" to be used in another iMovie of greater length than that of a trailer?

In addition to Tom's good advice, another method is to access the audio file in iMovie's package contents folder.
In Finder, in the Applications folder, right-click (or control-click) on iMovie.app and select Show Package Contents from the pop-up menu. Open the folder Contents>Resources. In that folder you will find components for each Trailer, including the soundtrack. The file you are seeking is named "SoundTrack - Romance.m4a".
Copy then paste the file to your Desktop (don't otherwise mess with items in package contents folders!). Open the file in QuickTime - it is titled "Love Story FC2". Opening the Inspector in QuickTime (Window>Show Movie Inspector) reveals it as AAC format. If you wish, as Tom indicated, you can Export the file from QuickTime in other sound formats, such as AIFF. If preferred, you can import either the AAC file or the converted file to iTunes (or other audio apps) for use as required.

How to remove a movie from iMovie theater

It was very easy to create a movie in iMovie, and click on "Share to Theater". But no amount of clicking, pressing delete, pressing Command Delete, or working through menus lets me remove the movie from Theater. I modified the Project, and now I want to replace it with a movie of the same name. What am I missing? How do I remove a movie in Theater, or at least update it with the latest?

Hello John,
It sounds like you should have been able to delete the movie from the Theater with what you were doing.
Checking the iMovie Help, this is what I find.
Add, remove, and play clips and projects in iMovie Theater - iMovie Help
Delete a movie from the Theater
Items in iMovie Theater can exist in the Theater only, or in the Theater and in iCloud. If you delete a movie from the Theater, it’s removed from iCloud as well. For more information, see Set up iMovie Theater and iCloud.
Click the Theater button in the toolbar.
Select the movie you want to delete.
Press Delete.
In the dialog that appears, click Delete Everywhere.
The movie is deleted from the Theater and from iCloud.
Best,
Nubz

Removing Wind Noise from Audio in FCP

Is there a way to remove/filter wind noise from audio for use in FCP?

I'm not sure if you're if your sarcasm is targeted at me or Apple but just to clarify:
By rolling off the bottom end prior to using a Noise Print style NR technique you'll get a far better end result than just asking something like SoundSoap to decipher everything.
Wind noise is dynamic. NR tools like SoundSoap and other basic noise tools do not adequately address it. Since much of the problem with wind is in the very low frequency range simply rolling that stuff off cleans up the signal significantly and sometimes is all you need. Adding noise print style NR after the LF has been eliminated will produce a much better result.
Another technique for changing the perceived amount of interference from a dynamic source like wind is to copy a chunk of relatively clean ambient tone and pasting it over areas where there is noise but no dialogue. This step will obviously not help of a strong wind gust happens over the voice but it does improve the overall perceived quality of the recording. I usually don't offer this suggestion right off the bat because it's more of a surgical procedure which takes a bit of skill. What most people are looking to do is just clicking on the "remove noise" button.

Removing Fan noise from lighting

First, thank you for your responses... Secondly, I know these problems should be thought of in advance and not to rely on post so I would appreciate help rather than criticism...
There is noise from the fans of the lights. A single person is speaking to camera in an inside room. I have reduced noise (set noise print –> reduce noise) in ST Pro, which got rid of fan noise (-45db), but distorts the voice so it sounds like he is speaking underwater. I added an EQ filter, but can't get this to sound very good...
I have Soundbooth CS5 and FCS. Thanks for any help.

STP noise reduction has a tendency to do that rather quickly. The only thing that helps is to reduce the amount of noise reduction which defeats much of the purpose.
First first adding some parametric eq to reduce the bad frequencies and then do a noise print and noise reduction, using less reduction, no lower than about 54dB.
You can also go into the spectrum analyzer and try to carve out the bad frequencies. This is more difficult than in Soundbooth's version, which is were I generally head off to for that sort of work.
Recently I've been trying Isotrope's RX noise reduction and find it miles ahead. Where I was using it I found I had to back up and reduce background in a lot more shots I'd previously just skipped over. It's one of those things that can be too good. It's spectrum analyzer is also quite good.
Good luck
