Removing ambient traffic noise

I have a project that I would like to remove ambient traffic noise that exists under a subject interview. I witnessed a very cool feature of STP2 at NAB 2007 using the Frequency Spectrum. They could isolate the specific frequency of the ambient noise and delete it. I can't for the life of me figure out how they did it now that I have purchased FC2. It seems to me they were able to view the frequencies in 3D in order to separate and delete the appropriate band. I've used the "set noise print", "remove noise" but that didn't work and they weren't the tools used in the demo. I spoke with Apple Support today and they couldn't come up with the tool I attempted to describe.
Any help would be greatly appreciated. I've scoured the net, the forum and discussion groups but haven't come up with the solution. Thanks.

Click on the file you want to edit in the timeline, and then click on the "File Editor" tab in the area below the timeline (you could also do this by opening the file directly, which would cause the waveform to appear in the upper middle section of the window.
When the waveform appears, click on the upper-rightmost button in that section, which will switch the display to the spectrum view. Then select the "Frequency Selection Tool", which has the same icon but on the left part of that tab.
Then you can select parts of the spectrum and press delete to remove noise.

Audio editing issue- remove ambient room noise

I am doing an audio run thru of my short program (puppets, etc). We had to do some VO work and have noticed the ambient room noise varies from scene to scene. On some it is OK, but others it is quite noticable. Is there a filter I can apply to control that? FC6 Thanks!

If you did this properly and sent it from within fcp, when you save in soundtrack pro and switch back to fcp, it should update properly. Then compressor and into dvdspro

Background Traffic Noise Reduction

Hello all,
I'm currently editing my short film and I have huge issues with background traffic. I've faught with Adobe Audition for about 2 hours now and I can't get a good reduction on my background traffic. I've used adaptive noise reduction and Noise reduction (Process) and I just can't seem to get a decent reduction without having weird noises that would just make everything worse.
If you want you can listen to it for yourself, I'm linking it with dropbox.The beginning is the worst I have plenty of other audio that has more backgrounf traffic.
Thank you in advance for you help! Cheers!

I couldn't find a link to your Drop Box but I can make a few general comments.
First, traffic noise is going to be very difficult to work on because it's constantly changing. Noise reduction is most effective on things like electronic hiss or an air conditioner running continuously in the background.
However, to give yourself the best chance, use the Noise Reduction (Process) version. Grab a sample of the background noise but don't try to get rid of all the noise at once. Do a very light reduction, grab another noise sample, then do another light process. Keep this up until you hit the best compromise between background noise and the sort of artefacts you've noticed. Depending on exactly what the noise is, you may find that increasing the FFT size helps.
Because the background will be constantly changing, you MAY find you get better results by breaking it up into smaller chunks with more similar noise problems....general traffic is different from a passing bus.
Which leads me to a final suggestion...if certain noises are a fairly specific frequency, instead of using NR, you might try to go to spectral view and use the marquee tool to draw around the offending frequency and either just hit delete or maybe the spot healing tool. This'll only work with a narrow frequency band--I was once able to remove a passing ambulance siren almost totally using this method--but a passing truck rumbling through a wide range of frequencies wouldn't really work.
Finally, you might find that some subtle boost in the fundamental voice frequencies might help your intelligibility a bit. You'll have to play with frequencies to find the right ones but they'll be in the mids somewhere.

Best Audio Filter to cut out traffic noise

I'm new to the audio filters. Can anyone suggest one that might help reduce the background traffic noise in an outside interview?
Susan

You can try using the noise reduction tools in SoundTrack Pro, but the best way to eliminate background noise in situations like this is to use a directional, dynamic mic when recording.

Using Mac, how do I remove the hiss (noise floor)?

Using Mac, how do I remove the hiss (noise floor)?

Hi! Well, at the most simple, Audition has a noise reduction effect...try Effects/Noise Reduction/Restoration/Noise Reduction (Process). Highlight a short section of your clip featuring just noise, not any sounds you want to keep. Turn the amount of NR down on the sliders to, say, 20% and the Reduction to, say, 10dB, hit "Select Entire File" and Okay it. If the noise is bad, you're best off to do several passes at low processing settings. Turn up the FFT size (on the Advanced menu) and grab a new noise sample between each process. FYI, the reason for doing it 3 or 4 times with small increments is that it results in a lot fewer unpleasant artefacts.
However, as others have said, use of Noise Reduction should be a last ditch option, not a normal part of the process. I have 3 different M Audio interfaces now and none give me enough noise to worry about. As a first guess from your description I wonder if it's your microphone that's noisy and, if so, no amount of playing is likely to fix it...the noise goes up and down along with the programme material as you adjust the levels.
So...a bit more info and maybe we can make some suggestions for you.

Removing microphone crackle noise from a video

Hi there,
Please could anyone offer some advice on how to remove a "crackly" noise from my video? The "crackle" appears to have come from the microphone that was clipped to a shirt, and as the speaker moved, the microphone picked up and recorded the scraping noise!
I have had a go with the audio effects in Premiere Elements, but haven't had any luck removing the noise, unless the sound gets distorted. I am new to Premiere Elements but have a gut feeling that I will probably need to re-record the speaker again. I thought I would ask the question, just in case there was some method I haven't found / understand yet.
Thank you

From within PrE, I think that you have gotten good advice. The ability to remove transients from Audio is a bit limited in a video-editor, and can take a lot of experimenting.
There is something a bit better, but requires additional programs to accomplish. Even then, experimenting and critical listening will be needed. The first is an inexpensive, but great audio program, Magix Audio Cleaning Lab. With just the default settings, it does an amazingly good job with such things, though might never be perfect. I then use Adobe Audition, which has a Transient Repair Tool, and must be applied by hand, for each Transient that remains. It is NOT inexpensive, but so very powerful. This ARTICLE will give you a bit more info, plus a link to the Magix program.
Also, I would check out what is inducing the crackle into the audio stream. Usually, this is because of a bad connection in the chain. Fixing things there, is the best course, for the future.
Good luck,
Hunt

WHAT IS THE BEST WAY TO KNOCK OUT TRAFFIC NOISE IN SOUNDTRACK PRO

I have watched apple pros knock out the sound of the boat noise and just had the people talking, could someone explain how you knock out that sound again, I am pretty knew to this program. I am trying to knock out the background sound of the traffic. Thank you for your help,
Bill

I worked on a project to cleanup up audio - where 'guerilla video' was shot in the streets of SF during the massive war protests - had:
a. sanitation trucks operating
b. wind
c. bicycle bell
d. heels/ footsteps
e. background voices
f. sound of the camera operators lens cap clicking against the camera body
g. other vehicular noises
I used:
Peak
Sound Soap
Eventide Harmonizer
Logic Audio / Pro plugins
Lexicon PCM 80
STP / plugins
and although we were able to reduce some of these, overall, I was quite unsatisified and realized, perhaps for the last time, that you simply cannot remove most 'aural debris' from a mix, period. If you want a quiet background, well now you know why most productions bother to shoot on sound isolated stages and love to yell "quiet on the set" (he).
And Ive had those who would argue with me in saying that 'old/dirty paintings can be cleaned up' - perhaps true however, usually the debris is on an outer layer and not mixed in much with the original artwork, at least to some extent. And even this kind of work is incredibly delicate and said to be quite difficult to do.
In the final analysis, the shooter was advised to realize that the very nature of the video - its completely urban setting, was still quite compelling.
fwiw

Removing head switch noise from VHS video

Hi experts,
I have imported a video from a vhs videorecorder - and now I want to remove the head switch noise by shifting the entire video 8 lines down and insert 8 lines black at the top and bottom.
How do I do this with Premiere Elements 11?
Thanks a lot for your help!

joeK
I think that the scale up ever so little (with Constrain Proportions Off) would have been the best, but if your image has problems with that (and as Hunt says can live with black bars), then
Approach 1 - On Screen Image Moved Down
The just moving the screen image down far enough to hide the switch head noise at the bottom of the frame. To do that:
a. Click on the image on screen, and use the mouse cursor to drag the image downward far enough to hide the switch head noise bar.
or
b. Highlight/select the Timeline clip, go to Applied Effects Tab/Applied Effects Palette/Motion Panel expanded, and increase the second value for Position to move the image downward on the screen.
The black at the top of the image that you generate in this process is not the color black but rather the program using black to represent transparency.
Before Position second value = 238.8 in this example
After Position second value = 250.8 in this example
Approach 2 - Cropping out Noise
Go to xf Effects/Transform/Crop and drag the Crop Effect into the video on the Expert workspace Timeline. Then adjust the Left, Top, Right sliders so that the image is not cropped at any of those edges. Move the Bottom slider from 0 upward to replace the switch head noise with transparency/black border at bottom.
Please review and then let us know the outcome.
Any questions or if clarification needed, please do not hesitate to ask.
Thank you.

I want to remove a specific noise

Hi.
To the point - I have some lectures with constant backround shaking sound. I've tried all noise/hiss reduction options, and also third party plug-ins. They help a little, but I want to try a different approach which I hope is more effective. I want to cancel or cut out this specific noise. But I don't know if that is possible. I've added a picture to show how it looks like. You see those small ripples? So I hope that if there's a way to make Audition to recognize them and to cut them out, that would clear up most of the noise. Could that be possible? I appreciate any help. Thank you.

Hi everyone.
So I tried spectral view, I never used it before, but I'm getting the point. The thing is that this noise is constant and also widespread, so there's no question of manually brushing it out. A magic wand tool like in Photoshop would be great in this regard. That would do the job to eliminate rattling. Mikromidas mentioned about markers, but I don't see a way to automark all the rattling noise in a way to set in and out markers to isolate the rattling. And then how could I create a script which tells Audition to clean up audio after certain intervalls?
So I guess I have to accept the results Im getting by using click/pop eliminator plus some hiss removal. Thanks for the input, atleast I know I tried all the options available, and got a little more experienced.

Removing Florescent Light Noise "Hum" from Audio Tracks using FCEHD

I have some clips taken under florescent lighting where the hum was discernable even during the sound check. (I was using external Electro Voice hypercardiod XLR mikes plugged into my Sony DCRVX2100, powered through a surge protector, monitoring the audio with Bose QC2 headphones). Using the same camera, cables, and mikes under incandescent lighting that day was fine - no hum.
Attempting to filter out the hum using the FCE Hum filter wasn't dramatically effective, even with repeated tests establishing that using a frequency of 60 hz, a Q of 40, a gain of -48, and the 1st and 3rd harmonics provided the most benefit.
Additionally I tried again with the FCE 31 band EQ filter, anticipating that the 50 hz and 60 hz filters would provide very specific improvements. Also tried were the LowPass Filter and the 3 band EQ.
I'd like to clean up the otherwise fine audio - any suggestions? I am considering buying a filtered power conditioner as I know that some of the problem can be "dirty" electricity resulting from the ballast of the florescent lighting.
Also, I noted that the numeric values shown for the gain using the FCE 31 band EQ filter oftentimes lagged behind the setting of the slider: returning the slider to the middle "0" position frequently didn't change the previous value of the gain shown. Is this another indication that I should just upgrade from my PowerBook G4 with 2 Gig of RAM?
Thanks!
James Mackay

Hello Jim,
And welcome to the Final Cut Express forum.
You are correct that the ballast generates the hum. Power conditioning is probably not going to reduce or eliminate it, because the old ballasts are magnetic. The only way I found to eliminate fluorescent noise at the source is to replace the ballast with an electronic one or replace the entire fixture with a T8 unit (they use electronic ballasts).
Removing that hum probably can't be done in FCE. Sound Soap can probably do it however, with it's ability to +learn noise+ and then remove that specific audio. The regular Sound Soap works as a plugin for Final Cut, which enables you to apply it within FCE.
At present there is also an 'SE' version available at 50% off however it only works in standalone mode, which means you would have to export the audio track from FCE, clean it and then re-import back into FCE.

Voice Over, remove light static noise

Hi All,
I am sorry if there has already been a post on this.
I'm a very new user to any form of audio editing software.
I have some small voice over files that I captured on my camcorder... I have the smallest level of noise that I would like to remove. Is this possible adn if so how do I do it? I have normalised the file.
You can only really hear the noise when you turn the volume right up.
Thanks for any assistance.
Regards,
Katie

>Ozpeter is right, but I've found that it's more efficient to highlight your section of noise in edit view, then go to Effects > Restoration > Noise Reduction. In Noise Reduction, click Capture Noise Profile and then make other adjustments as necessary.
Hmm... that's not quite what
I'd call efficient!
Highlight selection, and hit Alt+N. That's all there is to capturing a noise profile - simple as that. After you've done that, either hit Ctrl+A and open NR, or, just open it and select all from within it.
And if you don't like keyboard shortcuts, it's always worth remembering that in Audition, you get a lot more options from using the right mouse button. And one of these, if you highlight a selection in EV, is to be able to capture your selection as a noise profile directly from there.

Removing echo/room noise

I have an interview taken in a kitchen which, as a result, has some echo like qualities. Also, the door in the kitchen was open, and I didn't realize that the sounds of the nearby highway would be so distracting. So, with the echo and the highway noise, there is a lot of other noise going on besides the the dialogue of the person being interviewed.
I did a noise reduction but it really didn't help much; it made the audio sound tin-like.
Does anyone know how to reduce such noise???
Thanks. Gilia

If you have access to Soundtrack Pro you can do some editing there that might help. Although you can 'send' the audio track with issues to Soundtrack directly, I make an .iff file copy of the audio track and open it up independently in Soundtrack.
Select a section of the audio track that only has the ambient sound (street, noise, etc) but no voice. Under Process>Noise Reduction>Set Noise Print you can Soundtrack what is the noise you want to try and eliminate in the whole track.
Then you can select the entire track, do Process>Noise Reducation>Reduce Noise and see if that helps.
There are many other functions under Process>Effects that can help as well. I'll usually do a trial and error process, but you can monitor the results in real time and save that modification as a preset, then use it again in other parts of the interview.
Regards,
Mark Basse

How do I remove these "boomy" noises?

Hi, I have just finished recording a guitar tune and noticed that there are some "boomy" noises that I would like to get rid of or at least reduce.
I recorded using 2 x Shure SM57 mics (I know there not ideal for acoustic recording) and recorded into Audition CS6.
Below is a link to the recording, please listen for the boomy noises that I mention and please help me find a way to reduce it.
Thanks

Late reply here, but using some EQ might help. Try this.
Apply the Parametric Equalizer. Use these settings:
HP, 140Hz, 24dB/Oct
Band 1, 230Hz, -6dB, Q: 5.7
The HP filter attenuates the low frequency energy. A lot of the boominess is there, especially just above 100Hz and below. There are also some harmonics being generated, which are especially noticeable around 230Hz. It may be overkill to reduce that frequency for the entire track, but it helps a lot for the boomy areas - so I think it's worth cutting a bit there as well.
You may want to drop the high frequencies a bit around the 2-4khz region. They are especially noticeable with the above bass cuts.

Ambient wind noise-can I adjust?

I hail from the DVD Studio Pro side but with the FC studio I have done some limited work in Soundtrack Pro.
Project: MiniDV discs from a South Africian Safari. When the vehicles were moving the wind noise becomes obvious.
I've used noise print/noise reduction and SoundTracPro Autofilter to some degree of success.
Wondering if there is anything else I can do to push down this background noise without loosing the conversation?
Thanks

I think noise print function and some eq can help you at max
