Background Noise Caused By Quicktime

and I quote the title.
I have had this problem pretty long but now Ive head enough.. I'll explain the situation. It started when Itunes launched Itunes + quicktime Pack. At a fresh install of windows XP SP2 and only just the audiodrivers installed there was no noise at all. After I installed the new Itunes + quicktime pack the murmur was there. High frequency noise, somewhat outputting the things that the computer is doing. It reacts on mousemovements, drag and drop. and it never stops, atleast that is what I thought..
Until, I went to the apple.com/trailers site and hold down the volume button at the in Firefox opened quicktime player. Then the murmur was gone, but when I released it, it was back again. very weird.. In a few days im going to reinstall windows again, but I don't think that is the problem..
Any one else ideas what It could be ? It are mostly high freq. tones, those are the most annoying
thanks In advanced
Windows Based Windows XP Pro Currently Xp-32bit

I had the same problem but it went away after I put microphone into mute.
Hope it helps!

IDVD Background Noise (not on iMovie or QuickTime)

So I created several movies in iMovie with no issues. I can upload them to my website and play them back, YouTube, play them back in QuickTime, etc, with no issues. But when I convert them in iDVD and play the DVD back, I get terrible background noise in all sorts random spots. Can anyone help or provide advice on how to fix this (or a different software I could use besides iDVD that would resolve this issue)? It's extremely frustrating.

Thanks for the replies guys.

Capturing Video produces an annoying background noise (Webcam Live !)

Hello,
As the titles shows, I am experiencing a background noise every time I start watching the video the camera is getting on the screen. I can't remove this noise, even when I have muted the in and mic lines.
Does anyone knows how to block this noise.
Thank You !

@allenwilson88 ,
Hello and welcome to the HP support forums. I can totally understand your frustration about the fan noise. One thing you have to remember these things are mechanical and some times they need to be opened up and given a good cleaning.
When the dirt builds up the fans can not remove the heat from the chips on your board. And when your system is running a web browser like Chrome it is going to go off the chart because Chrome is a resource hungry software. I takes up most of your resources on your system when you are using it.
When this happens the chips work harder. This in hand cranks up the heat causing the sensors to drive the fan hard.
Could you post back with some information about your system. What I am looking for is the full Model and Product Number. Here is a link that will help you find this information.
How Do I Find My Model Number or Product Number?
Please post back with this information and i will get you the link for your products maintenance manual so you can see how to open your notebook up so that you can give it a good cleaning.
Here are a couple other links that may help.

Speedy 33 background noise

Hello,
We are finishing a project with the Speedy-33. The analog outputs are connected to a small amplifier for headphone listening. When connecting headphones directly to the Speedy-33 output or to the headphone amplifier, a background noise is heard : it sound like a tone. As you can imagine the amplifier jsut make it more audible. But the tone is present even without the amplifier ... so it is clearly from the speedy-33 output.
The speedy-33 is running in standalone mode ... as the USB connection tends to make a huge amount of noise.
We tried to listen to the Speedy-33 in "full bypass" (the labview patch is the mere connection of the input to the output) ... in that case only, their is no noise. As soon as we put any processing (exemple: we tested a single biquad between the outs and the ins) ... we get the famous background tone.
Any information about Speedy-33 background noise ... caused by the DSP or any other component on the board? Any advice?
Many thanks,

Thanks to all !
The main trouble is that when connecting directly the inputs to the outputs, the noise is not there. When a process is added between the input and the output (like a simple biquad as mentioned by PaGauthier), the board is generating a "sine" background noise.
In our application, the speedy is running in standalone mode using a DC power supply. The power suply was changed twice to make sure that it was not a noise coming from it (we used an analog regulated one, and a switching one with the same results)
The inputs are feeded with simple electret preamp using transistors or opamps (we have two preamps because we were thinking that is was radio frequencies interferences). The bandwidth of the preamp is quite large but the capsule itself is limited to 20kHz... and once again, when there is no process between the inputs dans the outputs, no background noise is added.
I have a simple question : Is there an aliasing filter onboard for each input ? If yes, I hope that designers did not simply added those filters at the nyquist frequency... In most cases, 80 to 90 % of the nyquist frequency is better... This could explain a 400Hz of aliasing : but couldn't explain that the added noise is a simple sine.
PaGautier and I will test the board next week to make it clear about aliasing filters.
Thank you for your help.

Lessening background noise when Amplifying a sound file (post noise reduction)

I have a video I have been tryng to clean up, that was filmed in an environment with some amount of background noise.
I managed to get the audio cleaned up to a leveI was happy with (but still retained a minimal amount of almost unoticable noise to keep the voise still sounding ok).
It sounds fine and perfectly loud in headphones but on some computer speakers even turned up to full volume you can barely hear it. (in the future I will try to film with a higher volume)
I attempted a few different methods to Amplify the sound slightly but this also increases the reminant of background noise.
Along with the basic Amplify, and Normalise I have also tried using a Hard Limiter (I don't know if I was doing it right though as it also increased the Background noise)
Can someone provide any pointers to only amplify the Voice and not the background noise? or possibly even suggest a way I can clean up the reminant background noise without causing the voice to become hollow and Tinny? Obviously redoing the Noise removal process just makes the voice more Hollow.
In the future should I Amplify first and then run the noise removal?
I am using Audition CS6

In Audition, Noise Reduction always seems to work best if applied in small steps, with different settings for each. The setting that makes absolutely the most difference is the FFT size you use. The thing to do at the outset is to use the default setting (4096 I think) but don't take too much off with that. Then change the FFT size to the maximum setting, take a new noise print from the results of your previous pass, and take the rest off with this setting. By doing this, you'll find that you can take away more noise before artefacts start to creep in.
It doesn't actually matter about the level of your signal when you apply NR, but to be sensible about it, in order to be able to monitor the results effectively, you should normalize it first, to around -1 or -2dB. The concept of amplifying a signal without amplifying the noise in it implies making the dynamics non-linear, and whilst that's possible to a degree with the Dynamics Processor, it's generally not a good idea - it makes everything seem completely unnatural-sounding.

Decode DTMF (touch tone) signals against background noise

Hi,
I have written a VI to detect the touch tone '1' DTMF signal (697Hz and 1209Hz) in an input received through a microphone. The VI reads the sound, assembles a waveform and then passes it through parallel bandpass filters tuned to 697Hz +/- 10% and 1209Hz +/- 1% respectively (the tighter tuning on the higher filter came after some trial and error at minimising nuisance triggering). The filtered signals are then squared and the DC signal compared against a constant in order to return a boolean output of whether the tone has been heard or not.
I have just about got this to work so that the tone can be detected without my own speech triggering it. However if I play music in the background this is causing nuisance triggers, presumably as the music contains the two desired frequencies. Also, when I clear my throat loudly that triggers it as well.
Can anybody think of a suitable method I could use to cause a trigger on the 697/1209Hz signal without background noises triggering it? I would like to keep the method as simple as possible as I would eventually like to replicate my VI in low-cost electronics, hence my use of bandpass filters.
Thanks.

I recalled that there is a minimum signal duration for a DTMF signal. A quick google search on "dtmf singal duration" returned several links stating that the ITU minimum duration is 40 ms.
A simple timer may be sufficient;if two of the eight frequencies are simultaneously and continueously present for > 40 ms, then you have a valid entry...

DVR620KU Makes Background Noise When Dubbing

Hi, I recently purchased a DVR620KU. I started dubbing VHS tapes to DVD+R. The VHS tapes sound good when I play them alone, but as soon as I begin dubbing to DVD I can hear background noise, like a persistent light tapping sound. Thus the DVDs end up with this background noise that isn't present in the original tapes. I tried different DVD speeds. I also removed the machine completely, plugged it into a different wall socket, and tried dubbing without the unit connected to any other devices. The noise was still present when I played back the new DVD. The noise is not present in DVDs that were not dubbed by this machine. At this point I am convinced that the Toshiba DVR620KU is the root cause of the background noise. Do you know what Toshiba's explanation is, and what is the recommended solution? Thanks.

The noise is initiating from the VHS playback, and then being written into the DVDs. The noise only occurs when the DVD is either dubbing or recording the L1 circuit (even when the L1 circuit is empty, the VCR playback is still affected while L1 is being recorded to DVD). When the DVD player is off, the noise is not present in the VCR playback. I'm not sure how to determine whether the noise is originating mechanically or eletronically. But it ends up as part of the sound transmission through the speakers. I'm not hearing something banging inside the machine, if that's what you mean. If you tapped on a microphone repeatedly while it was recording, this is what the output would sound like.
So far I've identified 7 VHS tapes that are affected by this problem, and 8 VHS tapes that resulted in excellent DVDs. I just burned a perfect DVD this morning. All the tapes are T-120 cassettes that were originally purchased as blanks. Several different brands and grades are represented. All of the "bad" tapes weigh more than 240 grams (average 257g), and all of the "good" tapes weigh less than 230 grams (average 204g). I know that blank T-120 cassettes generally become lighter over time, which means the "heavy" cassettes are probably generally older than the "light" cassettes. This also implies that the material was generally recorded with older VHS players on the "heavy" cassettes. The transition between the "heavy" and "light" tapes was probably around early-90's based upon the material on the tapes and when I think the data was originally recorded. So I don't know whether or not the weight actually means anything, although it could because mass can obviously impact mechanical vibrations. But the difference could also be that different tracking technologies were involved with the older, or heavier, cassettes and/or the machines they were involved with at the time the material was recorded.
I read on a different forum that VHS cassette tracking imperfections may be present all along, but they don't become audible until the digitization process amplifies some of frequencies involving the imperfections. I don't know much about that, but to me, it's plausible that the frequency processing and flow path out of the machine changes when the DVD player is recording. I'm not sure about that either, but something is definitely happening when the DVD recorder is on that affects the VCR playback on these heavier, older cassettes.
So, at this point, I can carry on knowing which tapes will be useful, and which will be problematic with this Toshiba dubbing process. The problem is what to do about it. Perhaps if I purchased another unit and ran the VHS output from the "slave" unit to the L1 circuit on the Toshiba, the problem might be fixed. Or, maybe this unit is defective, and if I exchanged it for a new Toshiba, the problem will be fixed. Or, maybe the Toshiba design includes this sensitivity, and the only solution may be to return it for cash refund and purchase a competetive product. Or, maybe the digitization process is what it is, and these old tapes are what they are, and there is no solution.
You said you have a DVR620KU and you've never experienced this problem. I don't suppose you have any old VHS T-120 cassettes that weigh ~250-260 grams? If you do, I would be curious to know whether you have the same issue. Thanks.

How can I eliminate the background noise on ishuffle?, How can I eliminate the background noise on ishuffle?

I recently bought a second hand ishuffle. I downloaded the music stored in my laptop on to my ishuffle. Whenever I play music on ishuffle I hear a background noise (sounding like a tin foil being rubbed). However this noise is not there when I hear the same music on my laptop. How can I rectify this?

That makes me sad. thannk you

Found Audacity for my background noise. Can I edit my audio files in the FCPX event folder in Finder?

I think I found the solution to my background noise problem using Audacity.
But can I edit my audio files that are in FCPX Event folder in Finder? Or do I actually have to edit my project all over again to put in new audio (edited by Audacity)?

No, copying the whole Project and Event is just too much of a waste of time.
Do this, in the Browser, select the audio file you need to take to Audacity. Export it as a Master File, and in the Settings section of the Share window, set Format to Audio Only. Set Audio File Format to AIFF. Set Open With to "Other" and select Audacity. Then pick your Desktop as the location to save the file.
In Audacity, do whatever it is you want and save it.
Back in FCP X, import the new "fixed" file, be sure to check the box to copy it to your Event folder.
Finally, if necessary, do a Replace edit with the new version to the old one if it has already be edited into a Timeline.

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.

Filtering background noise using two microphones

Hi,
I am new to Labview so please bear with me. I am trying to work out the sound vibration level emitted from a compressor. I have a microphone placed next to it but it is operating in a noisy laboratory and therefore I need to filter out the background noise.
I have another microphone to record the background noise. I think I might need to use an adaptive noise cancellation filter but cannot figure out how to make one on Labview. I have tried simply inputting the two signals and subtracting them but get an error saying "Resource requested by this task has already been reserved by a different task" when trying to run it.
Basically I am looking for the simplest way to get rid of the background noise in real time or in processing the signals afterwards.
Any help would be greatly appreciated. Please ask if you need more information.
Thanks a lot,
Sam

An ax (also spelled axe) is a tool for chopping down trees. I was trying to make a joke. Like some other experienced LabVIEW programmers, I do not like the Dynamic Data Type because it hides the structure of the data contained within it.
The subtraction technique is standard and simple. The biggest issue is phase shift. Suppose the two microphones are 1 meter apart. A sound arriving on the line through the microphones will arrive 3 milliseconds later at one than at the other. Sound arriving along a line at right angles to the line through the microphones and equidistant from both will arrive at the same time at each. At other angles the time will vary between those values. Compensating for that delay or phase shift is necessary to get good cancellation.
In addition the amplitude of the signals at each microphone will vary inversely as the square of the distance between the source and the microphone. For sources much closer to one microphone the amplitude difference can be significant.
Directional microphones will further complicate the amplitude variations. I think that two microphones are not enough to provide unambiguous determination of the direction of an unknown source, especially when there are multiple sources.

No "Background Noise Suppression" option ?

When using a headset mic, I?broadcast a? constant background 'hum/hiss' while gaming; using Skype; or even just recording my voice with windows voice recorder... This occurs when I am speaking and also (especially annoying) when not speaking.
Most onboard audio has an option to "suppress background noise" so that at the very least, the microphone will only pick up sound (or begin recording) upon detection of your voice, thus eliminating any constant whirring/humming/hissing sound in the background.
This becomes particularly annoying to fellow gamers (all of whom have expressed their desire that I turn ON "background noise suppression).
Of course, no such option exists in the creative control panel.
Why is there no option for this? Have I missed it's? Or could this be the result of some other problem?
My card is "PCI Express X-Fi Titanium Fatalty Champion Series."
I'm running a quad-core Xeon 5335- 2.33ghz, with 8 Gbs of ram.
Vista Ultimate 64-bit.
I have tried 3 different headsets/mics and get the same problem.
?Thanks for your help,...
Message Edited by Wallcrawler on 05-3-2009 03:39 [email protected]

Thanks for the suggestion... I am aware of this option and while it does?eliminate the background hum over my headphones, it doesn't get rid of the problem for people on the receiving end of my mic.
I just find it really odd that simple onboard audio has a background noise filter, but a soundcard that's over a hundred dollars doesn't.
When gaming with friends online, I never hear any hissing or constant hum from their mics unless they neglect to activate the "background noise suppresion" in their [onboard] audio options. Their onboard audio only activates the mic upon?detection of their voice and?even then there isn't any background hum.
I have searched the net and found a couple other posts regarding this same issue with Creative Soundblaster cards...
I honestly wouldn't have bothered buying this card if I knew it wouldn't have something as basic as a background filter option.
It's an available option?with most?[what should be far less superior] onboard audio.

Background noise with electric guitar

Hi, I'm playing my les paul into a cheap (like $100) m-audio fast track interface, and picking up the signal with the usb on my macbook pro. I am using the audio port to send the signal to my line 6 amp.
I am quite sure i have set all the necessary settings correctly in the sound part of system preferences but i still seem to be getting background noise when i play. If i turn on the noise gate it takes away the background noise on dead time but if i play anything clean and turn it up i'm getting a buzz or something in the background.
How do i get rid of this, do i need a better interface,or a studio to actually record in or what. should i use an expensive mic instead and put it next to my amp? im just lost. i want the best sound and dont know how to get it....please help

There is confusion here the interface says m-audio fast track on it. I got it from a friend that is all I have used besides garageband and my guitar. My cable is a monster and should be fine in my opinion.
I started garageband and opend an electric guitar track. with the clean combo.
My input was set to mono input 2 , input one gives me no sound and more background noise.
After that I still got background noise, its like a fuzz, i read alot of ppl talking about a ticking sound but its definetly not that. its just staticy
ill try the headphones though...any other tips?
