Reduce background noise and increase audio volume?

Hi!
I have a movie with very bad static/background noise and low volume. I've been playing around the NewBlue cleaner AB, but I have yet to get a satisfactory results. Any hints/tips that might help me out? Or is it not powerful enough to get a good result?
Also, I've noticed the volume becomes even lower after running the filter.
How do I adjust the "clip volume" in edit effects past 6dB? If this is not possible, why?
Thank you!

Well, increasing the audio volume is easy. But doing it without also increasing your background noise is much harder. In fact, unless it's of a specific frequency that you can filter out, it's pretty much impossible. That's why a lot of Hollywood movies and TV shows have to "loop" or re-record dialogue for a scene if there was too much wind or background noise.
The easiest way to raise a clip's audio level is to click on it and select Audo Gain, and then increase the gain level.
This, though, won't get rid of the background noise.
Bill Hunt has some tips that may be helpful.

HELP! "Reduce background noise" changes from audio clip to clip, even though the percentage is the SAME. At my wit's end...

I am working on a lengthy editing project and am near tears at this point. Any and all advice would be deeply appreciated.
I am using a2012 MacBook Pro running Mavericks (10.9.5) and iMovie 10. I have been using the "reduce background noise" feature in iMovie 10, with movies where audio is detached, and I have a series of clips stitched together (the result of editing, or adding voiceovers). I'll add 4% reduce to the first clip, and it sounds great. I do the same to the second clip and it sounds as though the setting is at 100% — even if it's at 0%. In other words, the audio is really distorted.
I have tried relaunching iMovie and the MacBook itself, to no avail. The first clip is fine, all those that follow sound horrible, no matter how I change the setting.
Again, any and all advice or suggestions would be very welcome. Thanks!

I'm not sure if anyone is going to read or respond to my plea, but just in case, I thought I'd better update. I went into our local Verizon store today and explained my problems. I was nervous to do so because I didn't purchase my phone there and didn't know if they'd refuse to help based on that fact. The local store of a competing carrier will not help you if your phone wasn't purchased in their store.
What I found out was that my method for pulling the battery was wrong. I didn't realize the phone needed to be turned on when you did that. I did it the correct way and now most of my problems are gone. The one problem it is still having is not being able to update from 2.2.1

MacBook Air microphone picking up background noise and not my voice?

Hello! I really like my MacBook Air. It is truly the best computer I have ever had. However, I was very disappointed whenever I attempted to use my MacBook Air's micrphone to find that it was picking up the background noise, and not my voice. I can hear my voice whenever I record something, but it is very quiet, like the background noise cancelling software is treating my voice like the background noise and the background noise like my voice. For example, it picks up every little bump on the computer and every click and press of the key, but it won't pick up my voice at full volume! I know it is not a software problem as I reinstalled OS X, and whenever that didn't work, I erased and reinstalled OS X. Any suggestions?

macbook Air condenser mic assy. is easy to remove and replace. (see pic below of Air mic assembly).
Mics are delicate instruments as is their nature, however the damage you experienced is either damage, or defect, nobody can know.
However I can accurately say without doubt its very rare what you experienced.
the little condenser unit could have been defective, and gave out, or myriad other possible's. I cannot pinpoint it over the web, even if I had it in my hands, still couldnt because youd have to dissect the tiny little mics to find out, and nobody will do that, just yank the old, and install the new ones.
a 'painless' repair however to be certain, quick and easy to do.

I'm using movie program how do get rid of background noise and put music over top of video

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?

Mic is too sensitive, calls constantly cut out. People tell me y loud, and it sounds like I'm in a tunnel. Any background noise, and call is completely cutting out. This occurs all the time, but more so using earphones with in cord mic.

I have iphone5 ios6 and the Mic is too sensitive, and calls constantly cut in and out. People tell me there is loud background noise and it sounds like I'm in a wind tunnel. Any background noise, and call completely cuts in and out and sounds as if call is dropping. This occurs all the time, but more noticeable while using earphones with in cord mic. I never had this problem with my old iphone4. Has anyone experienced this, and is there a setting that can correct this problem?

Same problem for me. So bad in fact that I can't really use my headphones for calls. I have tried it with several sets of headphones. My primary are the Bang and Olufsen headphones which were great with the previous iphone 4 and 3.
Apple please address this issue.

How to reduce background noise

I shot a few interviews I'd like to use for a documentary. All except one were recorded with an external mike. Unfortunately, the one recorded with the built in is very noticably worse quality. There's a lot of background hissing, etc when the volume is normalized with the other clips. The content of the interview is very good and I'd like to use it.
I know there's no noise reduction feature in iMovie 08. Can anyone recommend a way to improve the quality and reduce noise? Maybe Garage Band? Would iMovie 06 help much? Thanks.

GarageBand has some noise reduction tools that may help. I haven't played with them much so you will have to experiment. I am looking at GarageBand 09, but I think a similar function is in 08.
In GarageBand, your voice track will be a real instrument track, and you can apply a noise gate which suppresses the volume, and you can apply a compressor effect which is called vocal compression.
There may be better ways as well. If you post a question of how to do this in the GB discussion, you will probably get some good answers.
I would try GB first because you already have it. There are more sophisticated and more expensive tools available like Logic.
To get the clip into GB, there are a couple of ways.
The easiest way is to get a third party free application called MPEG streamclip.
In iMovie select the clip with the bad audio. Right-click (or control-click) and select REVEAL IN FINDER. You should see the clip in a Finder Window in an event file. Drag and drop this clip onto MPEG Streamclip. You should be able to export it using File/Export Audio... in Streamclip. Now drag the audio clip you just saved into GB. Do the sound edits. Then save it.
You can drag the file you just saved back into iMovie 08 and drop it on the clip where it came from in your project. You will want to select the Audio adjustments for the clip and turn the volume down to zero, so that all you hear is this new sound attachment.
You can also do this without MPEG Streamclip. Just start a new project in iMovie. Drag this clip (or clips) into the project. Share using QuickTime to an Audio only codec, such as MP3. And then edit it in GB as before.

How to reduce background noise using garageband?

I have a video file that contains quite a bit of background noise (just basic camera noise mostly) and I was wondering how to reduce or remove that using Garageband. I have read in other discussions that I could use the graphic equalizer, but I don't know what that is or how to use it. Does anyone have any ideas as to how I could get rid of this background noise?

I'd suggest looping a piece of silence in your sound in Garageband (using the c key to turn cycling on) and listening to just the background noise. Then open a 31-band EQ as an effect on the track and start pulling down frequencies. If it is mainly hissing and rumble, you might be able to eliminate much of it using EQ.
Another solution is to open the Visual EQ and check the analyze box, and then loop/cycle play back your track so it loops just the silence with noise. This will allow you to see in the Visual EQ window what frequencies make up your background noise. Then I'd suggest using a 31-band EQ and gently start pulling down the frequencies that are dominant in your noise. Go carefully and listen as you do it, you might be affecting they sound that you want.
To avoid making the audio you want sound thin and hollow, think about these aspects:
For male voices, most of the wanted sound is between 125 Hz and 8 KHz
For female voices: between 300 Hz and 12 KHz
So basically drag the faders on the EQ on the frequencies outside this range. I'd suggest a 45 to 60 degree slope down on the EQ, so it's not a harsh transition.
It does depend on your source audio. Is it music? Speech? I use the above as a guide You have to experiment and listen as you go. It helps to turn the EQ on and off during playback to hear the before and after your adjustments too...
This is great, oz.
But do you have a video showing how it is done ?
My source are vocal singing ...
Thanks

Enhancing voices, reducing background noise

I am using a HD camcorder to record people at work in an office environment for a research project I am undertaking. I am using Final Cut Express to edit and enhance the raw AVCHD stream, and in particular the quality of the audio.
Does anyone have any useful tips for enhancing the audio within Final Cut Express (in particular the best audio filters and settings to use). I want to 'bring out' the voices of those being filmed, whilst reducing the background noise from the office (doors slamming, clicking of mice, rustling of paper, etc) in order to hear more clearly what is being said.
Any tip gratefully received!

I don't think anyone can tell you exactly which filters and what settings to use as it all depends on your particular noise.
Try the EQ filters and experiment raising and lowering the different sliders to see if you can accentuate the voices and reduce the noise ........ though very often little can be achieved.
Your best bet would be to record the voices with tie-clip microphones (especially wireless ones) as that would give you near perfect audio.

Easiest way to reduce background hum? Increase vocal bass?

Hi guys,
I'm editing a short interview, shot indoors, and im trying to improve the sound.
I'd like to reduce general household hum and increase the bass in the woman's voice. The interviewed subject is an elderly woman with a deep southern accent and im trying to preserve the unique quality and tone of her voice - so far reducing hum with AUHighpass has lost vocal quality.
I increased the gain on AUFilter to add bass but it didnt work. Im playing around with AUGraphicEQ but not much success yet.
am reading about my options here: http://www.digitalrebellion.com/blog/cats/22/ but probably need more detailed guidance.
Thoughts?
Thanks.

ha i wish jim! not every job can afford one though and you gotta start somewhere,
think of it as my first day at work... im keen to learn.
i've run the clip through a noise reduction by following the instructions here:
http://www.geniusdv.com/weblog/archives/reducingbackground_noise_in_soundtrackpro.php
its not totally great... i've isolated the noise and tried a few things, it comes out either sounding a but watery and warble-y, or it just doesnt do too much. will keep playing around but any more ideas are welcome.

SMC Firmware 1.4f12 has stopped my RSD (and increase speakers volume) but..

My black MacBook week 23 began RSD about a month after purchase. Initially I blamed the meditarranean summer, that's usually hotter than the suposed MB operational range of 10-35Cº. Finally, when RSS went worse, in mid September I called Apple and got a case number, but I didn't send for service because early repairs get RSD again more sooner than later
Following some hints on forums I almost reduced to zero the RSD ocurrence in normal use, but the MB kept on crashing under yes >/dev/null/ & test on cold or warm, but not on hot.
Yesterday October 26 I installed the SMC firmware 1.4f12, and I haven't had no more RSD even with the stress test. Although it's soon to consider an ultimate solution (if some wire isolation is melted/damaged by heat, no firmware update will fix it) I consider a big step ahead that RSD can be avoided by ignoring the erratic temperature sensor data that suposedly the overheated wire defect caused
Anyway, let's see if it works for all (or at least most) the affected, mine was not one of the worst cases, but some users claim to have had RSD after this firmware update, so let's wait and see
By the way, have you noticed an increase in volume on speakers? I've had, and some other users too, but some don't. I don't know how it can be related to firmware update, but it seems to be somehow

You should check if the SMC firmware update is actually installed, in Applicatios/Utilities/System profile Hardware is the SMC version that should be 1.4f12 after last update.
If you don't have the SMC firmware update application in the Applications/Utilities something in the download and installation process seems not correct, because after downloading you must do the actual update from that application with some warnings about being plugged in and don't interrupt the process.
The fan behaviour has improved on my MB after that update, sounds estrange yours is not. But maybe my Fan Control applications have somehow change that, I use smcFanControl and Lobotomo Fan Control, search the web if interested, I prefers the last one because it gives more options thatn smc

How do I eliminate the delay in reducing background noise with each new clip?

My microphones pick up a fair amount of background nosie. At 60% reduction with iMovie's built in editor it sounds perfect. The only problem is that it takes about .5 seconds to go from zero reduction to 60%. If this were only at the start of the new movie, that would be fine. But this occurs at every new clip. I'm editing together a long series of short, ten second clips...so there is a distracting hissing of background noise once every ten seconds. Any help on this would be great.

You may have installed a persona.
You can uninstall your current Persona and revert to the Default theme (Firefox (Tools) > Add-ons > Themes).

IMac 24 line-ine a lot of noise and no audio...

Hi guys!
I've a problem...i've tryed LineIn..and other utility but no luck. If i plug my xbox360 outpu or a mp3 output into the iMac linein's i obtain a terrible noise and a really really low sound....but for 2 times the audio worked fine...and at a certain point when i've streached the wires the noise was gone...but no is totally only noise...HELP

Hello Eidan
Welcome to Discussions
To prevent damage to your iMac's or xbox's audio system that cord should no longer be used if you find it has a short or the wrong end???
The Mac needs to have a Mini Stereo plug for input to it's jack, look at the one in the link below to compare the plug end with the one you have.

How to reduce background noise of a conference recording..

I've made a recording on a digital camera in a conference. There's background noise, hissing and people coughing, cutlery noise etc that i'd like to minimize so that the speaker's voice comes clearer.
Anyone with good references or tips for that?
Many thanks..

if the sounds are during the speech, there is no really perfect solution. you might try using the graphic EQ to lower some of the higher frequencies (cutlery and hiss) and boost some of the lower-mid tones (where speech is). also the Gate can be used to silence low bg noise in the silent passages.
