Removing a Buzz

The bad news is that I have a buzz in my audio, the good news is that I have a constant buzz in my audio. The level is steady, and the tone doesn't change.
What is my best option to get ride of this annoyance?
I only have FCP HD to my disposal.
Thanks.

Okay, while I wait for a render to finish I thought I'd tell you how I fixed the issue to help anyone else who runs into the same problem.
Step 1 was to find where in the spectrum the buzz was. I used the graphical EQ plug-in and adjusted each spectrum until the buzz went away. In my case it was 10,000-12,000 range.
Step 2: I dumped the graphical EQ plug in and added the Parametic EQ. I punched in the 10,000 for the freq, turned the gain all the way down and then adjusted it slightly until it .leaned it up as best it could (it may not be gone totally). Play with all settings until it sounds good.
Step 3: Since FCP doesn't stack plug-ins too well, I nested that audio into a new sequence. I then added the plug-in again to the clip and cleaned it up even more. Tweak the settings until it sounds good. I could give you numbers, but I wasn't even paying attention to them, I just listened. The buzz was still there, but not enough to be noticable anymore unless you were wearing headphones and really listening.
If the buzz is still there, keep repeating the nesting and applying of the filter until it's gone.
Step 4: Since I killed a lot of the 10,000-12,000 range, this also killed the high end of the vocals. I once again applied the same plug-in, however instead of gaining down the sound, I gained it up. The base audio is now clean and gaining that up should yeild good results.
All of this did require some rendering, but it was only 5 minutes render time per pass of 60+ min of raw, stereo footage.
Best of luck.

How to remove a buzz?

Sorry to ask this here if it's not appropriate.
I use Logic. I have a vocal audio track that's got a mild
buzz in it, probably from a bad mic grounding situation
that I was not on top of when the track was recorded.
Any recommendations of plugins/techniques to deal with
such a thing?
thanks

Hi
Have you tried to use the noise analysis and reduction feature of Audacity?
Check it out. It can do a great job w/some experimentation.
Its freeware.

Removing sound buzz FCE

I videotaped a presentation - the speaker was using PP projector close to him (close to his lapel mike) - sound volume on my camera was quite low. Now I have buzz from the projector equally loud to his voice. Is there away I can remove the projector buzz?

You probably should post that question in the Final Cut Express HD forum.

Removing or limiting GSM Buzz

Before I knew it was a problem, I recorded a child's performance too close to my iPhone (1G). The video recording now has the dreaded GSM buzz mangling the audio.
Is there a reliable method to remove the buzz from a video recording? I have FCE 4, but I have not seen a reference online or elsewhere that describes a tool or process.
Thanks.

The process will be like killing the patient to cure the ailment.

Powerbook (digital audio) and 1/8" jack NOT getting along

ok see if you can help me troubleshoot this.
i bought two of these cables:
<http://www.cablesforless.com/index.asp?PageAction=VIEWPROD&ProdID=2779>
"Our Custom Made 3.5mm Male to 2-Male 1/4 inch phono plugs audio cables are perfect for connecting your speakers and microphones. These cables feature Belden's 1800B digital XLR cable and Steren® precision machined connectors. To ensure maximum signal integrity and protection from RF and electromagnetic interference the cable also features a Beldfoil® shield and fully shielded connectors. Professional termination using high grade solder ensures optimal signal transmission. Designed for optimal sound quality, Belden's performance speaks for itself. Compare Belden's specifications (below) with those of other digital XLR cables and see for yourself how Belden cable is unmatched. Belden Brilliance® teamed with Steren Connectors brings audio to life!"
sounds good, right? they both exhibit the following symptoms.
i'm using it in the headphone jack of my powerbook g4 15" and going out to a little mixer so i can hear system audio, itunes, etc. through my system. this longer cable is replacing a monster cable of the same kind (but shorter).
i'm getting absolutely HORRIBLE buzz when i plug it into the headphone port. if i jiggle it a bit i can get it to behave but only if it sits just right.
on a crt imac and an older titanium powerbook G4 the issue is much better. i still hear a line hum. i wouldn't want to record like this, but it's not a nightmare.
on an ipod plugged into the power adapter it works beautifully. however, i CAN get it to buzz horribly if i jiggle the plug as i insert/remove it.
eyeballing it with the monster cable tip, it looks exactly the same.
so on one hand, the monster cable works great in all uses.
the cablesforless cable works terribly on the powerbook but nowhere else.
now here's a clue: the powerbook G4 has combination analog/digital input and analog/digital output jacks. i haven't been able to repeat it reliably, but the cablesforless cable seems to be able to trigger the digital interface part, as evidenced by a red light shooting out of the port.
unplugging the powerbook totally removes the buzz.
i get the buzz when this cable is in EITHER the input or output jack.
tried a different power supply in a different jack in the same room... same results both ports (slightly different tone to the buzz)
if i remove the little mixer and plug the 1/4" cable ends into two inputs on a practice amp, i get the same issue.
finally, i got another digital audio powerbook g4 15" and the connection seems to be slightly more reliable, but still problematic.
PowerBook G4 Aluminum Mac OS X (10.4.5)

For starters, EPUB is a profile of XHTML, not HTML5. Further, audio and video support are part of the recently-approved EPUB3, which the release notes for ADE 1.8 explicitly say is not yet fully supported. Specifically, <epub:trigger> will allow you to use audio and video: http://idpf.org/epub/30/spec/epub30-contentdocs.html#sec-xhtml-epub-trigger
Do these EPUB files that you're not seeing in ADE pass validation? http://validator.idpf.org/
Basically, it sounds like you're trying to do things that ADE isn't supposed to support yet, and in a way it is unlikely to ever support (since ADE is known to be pretty conformant to the EPUB standards, it's very likely it will support the EPUB3 version of doing things rather than the hackery I've seen for Apple's reader).

Weird audio problem.

I have both my computer and my ipod hooked up to the same speakers using a (fairly high quality) splitter cable. Usually if i turn up my speakers full blast without audio playing there isnt any hum or buzzing. However, i noticed that when my ipod is plugged in to the speakers there is a buzzing sound if i turn up the speakers enough.
I tried various things to fix this problem, and nothing worked. I used one of those ferrite cores around the audio cable to reduce interference but it didnt work.
I noticed that the following things got rid of the buzzing:
-Having the nano plugged in both USB and audio, but removing the audio in from the PC
-OR unplugging the USB cord from the nano
It seems that by having my iPod plugged in through USB and audio and having my PC plugged in to the speakers gives this interference.
Does anyone know what this problem is? Has anyone had this problem? And does anyone know how to solve this problem?

Yeah, a ground loop is probably the cause of the buzzing. As the name suggests, this is when the ground lines are connected into a loop.
When you have this loop, the magnetic fields around you generate a current in the cables which will be heard as a humming or buzzing.
Your loop seems to be: Computer -> splitter -> iPod -> Computer
Cutting the loop (by disconnecting one of the cables) will remove the buzzing.
If you absolutely must have everything connected, you should be able to reduce the buzzing by reducing the area of the loop and twist the USB and audio cables around each other.

Noisy Transitions

There seems to be a new bug with the 7.2 update, such that audio transitions applied to the beginning of a clip will produce a very loud buzz, but only when you play from before the start of that clip. If you start playback at the beginning of that clip, it seems to work fine. It also does not seem to affect audio transitions between clips, or at the end of clips.
I'm seeing this using AVCHD media on Windows 7.

Also experiencing this with wav files, 16bit/44k and 24bit/48k (haven't tried others). This also affects my renders, but manifests with a grinding stutter sound rather than the buzz usually.
Also, this has started causing audio to totally mute after a buzz. I have a Dynamics audio affect applied with the compressor and limiter sections enabled. The master meter (Audio Track Mixer panel) reads about -295 dB. Clicking to bypass "AGOn/Off" (even though it is already disabled in the Dynamics effect's interface) gives me audio again, but it doesn't remove the buzzes.
I can also get audio back by disabling the Limiter, either from the dropdown control on the Audio Track Mixer panel or by openning the effect's settings panel and unchecking the box for the limiter. This also doesn't remove the buzzes, but they do seem to be amplified by the compressor's MakeUp setting, so I'm guessing the buzz is added before it hits that part of the signal chain.
I don't know how much they are connected, but I hope this helps.

BF2142 Orbital Strike no

Hi, I keep getting this weird buzzing noise whenever near an Orbital strike. I've tried changing the setting between low, medium, and high as well turning on/off eax with Hardware renderer. Nothing removes the buzzing noise although it does sound less noisy when on a lower quality sound setting. I?turned off the onboard audio in the bios as well as removed all the drivers for it. The rest of the systems drivers are all up to date. System goes as:?WinXP sp2AMD Athlon 64 X2 4200+Asus A8NE mobo2GB DDR400ATI Radeon X900XTXSB Li've 5. It works fine on software renderer but then everything else doesnt sound as good then, and the noise only occurs on the orbital strike and nothing else.

I have the exact same problem but?I have an x-fi?and just like u say it's ONLY during the orbital strike. but for me it's more of a crackling then a buzzing?(I thought this was probably x-fi related but u say?u have a sbli've 5. )?when i check the card right after playing and this noise happening the x-fi?chip is VERY HOT! and i was wondering if this problem is more likely with the earlier x-fi?cards and if maybe i could solve it by getting a newer one with a heatsink, also if anyone can help then just so u know i got an asus p5w dh deluxe with the intel 975x and i had the same problem when i had the card on an asus p5p800 with the intel 865p chipset, it seems that i've tried absolutely every possible solution i can think of or have found online except for buying one of the newer heatsinked ones. (that is other than this one guys solution were he replaced 6 of the jamicon caps with panasonic caps, and it supposedly fixed this same problem for a while but not permanently...) any help and or response would be greatly appreciated.Message Edited by SilentCrusher on 02-8-20070:26 PM

When i plugged my ipod into the computer it started to make buzzing and screeching noises. It became hot so i removed it and then the screen froze while it continued to make these noises. I have never had anything like this happen.

When i plugged my ipod into the computer it started to make buzzing and screeching noises. It became hot so i removed it and then the screen froze while it continued to make these noises. I have never had anything like this happen. (never gotten it wet or had it exposed to extreme temperatures) It is also unresponsive to any buttons on the ipod and it didn't show up when i plugged it into my computer. What do I do? Also if it is unfixable could i get a free one from apple?

Large buzzing on my DV tape-how can I remove it?

Unfortunately we had a problem when filming, and a quite large buzzing noise is heard in the background, and the voices (an interview is going on) are quiet. Are there ANY applications, or otherwise options in FCP or similar applications to reduce or get rid of this noise?
I'm desperate!
Thanks

you can do this relatively easily using a noise reduction/ removal tool, in an audio application, e.g. http://www.bias-inc.com/products/soundsoap/
All my audio editing stuff is done on pc (boo hiss), so I'm more familiar with Sonic foundry's noise reduction, but the concept is the same. the app "learns" which parts of the sound are noise, and then filters it out, using a variety of methods.
the best results will be obtained if you have some audio that contains only the noise you want to remove. Point the tool at that section first, it learns which parts are noise. then apply that setting to the entire audio file...
if you can't get this app, and are really desparate, and the audio isn't too long (e.g. a matter of minutes, not hours) then I could even have a look for you....

How do i remove buzz and hiss from audio track?

I'm using Premiere Elements 13, Windows 8, 64 bit
My original film has some hiss and buzz that I would like to remove. I tried applying DeNoiser and New Blue Hum Remover, but neither seemed to make a difference. Perhaps I need to tweek the tools to make them suppress more of the unwanted sound? Any suggestions are welcome. Thanks.

Just some quick things to check out for now.
If the Premiere Elements audio effects are not working for you, please check out the noise removal offered by the free audio editor named Audacity. Have you used that before?
http://audacity.sourceforge.net/
Here are Audacity suggested how to. Think noise reduction rather than noise removal.

Buzzing and skipping when removing or inserting headphone jack

While listening to audio through iTunes, switching between the internal speakers or headphones via removing or inserting a headphone jack, often results in a loud buzzing noise. Pausing iTunes eliminates the sound, but it sometimes comes back when I press play once again. It also sometimes results in the audio skipping, and the entire computer freezing, while the sudio skips. What the **** is going on here? Do I need a new sound card?

Try resetting PRAM and SMC.

Need to remove a guitar buzzing sound

I have an old Strat that is a bit noisy. Just picked up a Mogami chord and it helped reduce the buzz a lot, but there is still some there. I was wondering if there was a noch filter in the EQ to lower just that frequency. Also, does anyone know what that frequency might be? I don't think it is a 60 Hz hum, but a higher sounding buzz.
Thanks

You might try turning off the lights in the room and checking for other electrical interference. I put Christmas lights in the studio and turn off the main lights and that got rid of any buzz I had.

Removing Buzz

Hey everyone,
just had a quick question that I haven't been able to figure out. I recorded a musical and took the feed from the soundboard directly into my camera mic input, however when it went through the camera it created this faint buzzing sound. I've included a link to a sample of the audio from a silent part. any ideas on how to get rid of it without effecting the other sounds?
Thanks in advance!

HP laserJet 5200dtn making buzzing/humming noise after printing

Hi,
We have about three of these units in our office and one of them has recently began to make a loud buzzing/humming noise during and after printing a document. THe noise last about 5-10 seconds after the print job completes. I can also make the printer buzz by removing the duplexer and puting it back in. The printer seems to load and then the buzz noise happens, again for about 5 seconds. I am aware of normal noise from these printers and this buzz is not normal.
This noise gets louder as the day goes on. Could this be a fan motor going bad? We need to do somthing to get it quieter.
Any help or suggestions?
Thanks

any suggestions?
