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.

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

How to reduce background noise level using Premiere Elements

How do I reduce the background noise level using Premiere Elements?

Welcome to the forum.
PrE has a few Effects, that might help, but an Audio-editing program is much, much better. I use Adobe Audition, but the free Audacity is pretty handy.

How to reduce background noise while recording in iphone?

I am actually recording voice in iphone. How can i ignore the background noises other than the person who is speaking...
Can anyone suggest me any idea pls ?

There is no filter in FCE that can eliminate background noise separately from the sound you want to preserve.
SoundSoap can do this.

How to reduce background noise in Final Cut Express

I have a video shot on the beach with a Canon 5D Mark II internal microphone. The voices are pretty clear, but the background noise is a little too much. I noticed there are a couple dozen filters available, but I have no idea what they do or which to use. You can look here to get some idea of what I mean, http://www.youtube.com/watch?v=c-wkrvx6q9o .
What's the best way to do this? Thanks.

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.

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

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.

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.

How to delete background noise on home video

How do I delete background noise on home video? Am transferring old Sony Camcorder tapes to DVD, using Adobe Premier Elements 11, Windows 7

Grandmaomi
Do you want to delete the whole audio from your home video and replace it with something else or do you want to do as you describe "delete background noise on home video"?
If the latter, a lot will be dependent on the nature of the background noise? Have you worked with any of the audio effects under fxEffects Tab/audio effects.

Please see the description of the audio effects described under "audio effects" in the above Adobe document on Effects Reference.
If one of these noise removal audio effects does not work for you, you might explore Noise Reduction in the free audio editor Audacity.

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.

How to reduce the noise in PCIe-6321 acquisition, to optimize wiring.

Hi all,
I want to optimize my wiring in term of noise reduction. I use a DAQ PCIe-6321 in my application. I want to acquire an analog signal from a sensor (+/- 4 Volts, resolution of 2 mV, output impedance of 100 ohms) using the DAQ. The frequency of the signal is below 2 kHz. My first question is about the most suitable cable to use (shielded, twisted, etc.)? What is also the best suitable input configuration to choose in Labview (differential, RSE or NRSE)?
Moreover, after processing of this data under Labview, I want to power an audio power amplifier (input impedance equal to 10 kohms) using the analog output of the DAQ. What is the most suitable cable to use to reduce the noise? Are there any other tips to optimize the wiring?
Thank you for your help and suggestions!
Cedric

Hi guys,
I know that it is a bit late to reply but that is the perfect topic for what I am looking for!
I am currently working with acquisition systems using either PCI-6221 or PCIe-6321. Those systems are exactly the same but the results are different (see picture enclosed). We can see spikes and noise with the PCIe-6321 while we have the same conditions of measurements.
Here is the NI setup:
- PCI-6221 + connector block CB-68LP + cable SHC68-68-EPM
- PCIe-6321 + connector block SCB-68A + cable SHC68-68-EPM
In one of the system equipped with PCIe-6321, I replaced all the devices like cables, detectors, motors and it doesn’t change anything. I also swapped the computer for one equipped with PCI-6221 and it works fine. It means that the problem really comes from the acquisition card.
So my question is: why is there such a difference between those models? Do I need to change the configuration in the card?
Thanks in advance.
Maxime

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.
Adobe Premiere Elements 11 * Effects reference
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?
Audacity: Free Audio Editor and Recorder
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.

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
