High pitch noise when recording audio using internal mic

The issue I am having is with the internal mic. When recording audio using quicktime or garageband.It is a high pitch noise that stays whether i am speaking or not. The fix i found was to lower the input volume of the mic in system preferences. However, this causes my voice to be recorded so low that audio is barely usable unless volume is all the way up. Looking around the web I found this gem:
http://www.usingmac.com/2009/6/18/recording-speech-with-garageband-2009
This help me get rid of the high pitch noise for Garageband. The noise still there for Quicktime. Any ideas on how I can keep the same mic input volume with out having to listen to the high pitch noise?
Any help is appreciated.

Did you do the usual stuff, such as reset PRAM?
http://support.apple.com/kb/HT1379
There are some sound settings in PRAM, although I think it's only for sound output.
Also, as a test, I would create a new admin user account in System Preferences Accounts pane
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8235.html
Log out and log in to the new account (do not use Fast User Switching). In the new account, try recording something using QuickTime, and note if this problem recurs. If it does not, you have eliminated a few possible causes, such as a problem with the overall system installation or a hardware issue, and isolated the problem to something in your normal user account.

High pitched noise when recording w/ M-Audio Producer USB Microphone

hello,
I have an M-Audio Producer USB Microphone. Recording with GarageBand, nothing else connected, using an the Apple AC power cord (three pronged ground).
When I record with it plugged into the USB port closest to my FireWire port there is a constant high pitched noise.
When I record with it plugged into the USB port furthest from the FireWire port there is no noise at all (as it should be).
What's wrong with my USB port closest to the FireWire?

I am having major problems with iMovie (and iDVD) ever since I upgraded to OS.X.10.5.6. I had to scrap my last promo-video. I am now recreating it very gingerly saving as I go but I am now stuck again. I am getting the digital audio screeching under my video clips when I extract the audio and under insert titles and transitions. Does this describe your 'crickets'?
I have clean video and audio signal from my camcorder. Check your cam' playback to verify. After three attempts I do have clean material in iMovie but cannot proceed until I resolve this issue. I ruined my last video when I extracted the audio and ended up with a garbled rumble which I could not reverse.
I have another question elsewhere regarding burning to DVD but I now need to resolve this before I can get to test the recommendations in the reply.
I hope I have helped focus your symptoms. I also hope there is an answer out there for this issue.

High Pitched Noise When Recording From iSight Camera

I apologize if this has been asked before. I did a search on here as well as with Google.
Whenever I record a video clip using the built in iSight camera I notice that there is a constant high-pitched noise embedded in the clip. You don't hear the noise during recording, and otherwise the audio is crystal clear during playback, but I can't seem to figure out what is causing this noise. Video clips I import into iMovie don't have this problem. Has anyone else experienced this problem? How can I prevent this from happening with future recordings?

Hello obsidianspider
I am sorry to report that you are one of about ten people who have posted here about audio noises during video recordings with MacBooks. I listened to your YouTube clip, and I believe you are hearing something. I can hear the muffled "thumping" of background noises being amplified because there is no voice or other close sound being recorded in your video, but my old ears do not hear anything high pitched in your video (or anywhere else for that matter.)
I am sure Apple is aware of the issue, but with so small a number reporting this issue among thousands of MacBooks sold, I understand why there is not yet a kBase technical article on this subject.
I expect that Apple searches its warranty & repair work for quality issues and trends, but, if you have not (and do not) contact Apple or your retailer for service on this issue, please report your problem via MacBook Feedback so Apple can accurately record the magnitude of this problem. Unlike posting in this user forum, "Feedback" reports go directly to Apple.
We users who post here have found no solution yet, so the problem appears to require professional service for resolution.
However, if you are willing to try a test, please post back and tell us whether video or movie clip recording applications other than Apple's give the same audio noise you hear when using iSight with iMovie. Apple's QuickTime Pro has already been tested and found to exhibit the problem.
If you have access to an external microphone that can be located away from your Mac while you record video, you could also test to see whether you are recording a physical sound coming from your Mac or electronic noise being produced within your Mac's circuitry.
If you want to read the suggestions we have offered for minimizing your audio noise in video recordings, take a look at the suggestions offered in Eemma's thread, which was the first to report this problem. The suggestions for minimizing noise start here:

High pitch whine when recording audio & voiceover in iMovie

I have read other posts on similar issues but found no resolution
Issue:
When recording video in iMovie there is sometimes a high-pitched whine which renders the video useless.
The problem was intermittent ... annoying but I wokred around it by re-recording the video enough times to finally get a "clean" copy.
Now I am recording voice-overs for some clips and the awful whine is present in ALL the voice-overs.
I have tried the "trick" of using brighter light. No joy.
I have tried adjusting the microphone settings. No joy.
THis is an older macbook ... so I can't trade-in for a new one on warrantee.
Is Mac's internal microphone defective? I have read enough other people have similar issues to think this.
I am doing educational videos. My initial joy at being able to record a video on my macbook is changing to despair as I have wasted hours of time on tech problems like this.
Anyone have a real fix?
Is the built-in camera and mic just shoddy junk which doesn't work well?
Thank you

ITunes high pitch noise when in full screen on 27" iMac11,1

Hello,
When running iTunes 10.5.1 in full screen mode on Lion 10.7.2, I get a faint, high pitch noise coming from my speakers. If I run iTunes in a refular window, the noise does not manifest itself. I can switch back and forth between one full screen app and iTunes, and the noise goes on and off and only manifests itself in iTunes.
Has anyone else experienced this?

I think I've found a workaround. The problem doesn't only happen in iTunes, but also in the Finder's list view when in full screen.
The workaround is to use Shades, a small utility that creates a uniform black color mask over my screen. All I had to do was set the brightness of my screen to 100%, run shades and lower the "brightness" using that utility to something comfortable for my eyes.
I think the issue comes from the high frequency flicker that the LED back light uses when the screen is being dimmed. For some reason, the speakers pick up on it when in list view... Why only list view? Beats me.
Anyway, the Shades prefpane can be downloaded from the following URL:

I hope this helps.
All the best!

To Apple Engineer. I hear a high pitch noise when surf flash-intesive sites

Hi. All.
I have a Aluminum PowerBook G4 1.25Ghz SD. I agree this is a great machine. It has a somewhat out-dated G4 Chip in it, I can do almost everything I need.
I've been using this powerbook for 2 years. Since sometime ago, I've heard very annoying "Hige Pitch Noise" from PowerBook. From further investigatin I found that this was a problem related to G4 CPU Processor throttling- so called "NAP" status. In Flash-intensive Web site, I clearly hear the noise.
According to solution suggested by talented apple user, I did followings.
1. Download or Install Developer Tools.
2. Download and Install CHUD tools from ftp://ftp.apple.com/developer/ToolC...ormancetools/
3. After installing chud tools, there maybe Processor pane in preference app.
4. In that processor pane, you should uncheck "Allow Nap" to reduce the notorius High Pitch Noise.(warning: it may increase the power consumption and temperature of CPU a bit, and of course you would see more frequent activities of CPU fan than before)
5. feel the silence.
To Apple.
I think this solution should be suggested from you not users.
Why we investigate, search the web for thosand of bucks PowerBook. Please fix this annoying(yes, annoying enough to cause headache) problem in next OS update.
To readers.

X-fi Extreme Music - Mouse making high pitched noise when moved

? Whenever I move my mouse my headphones make a very high pitched noise. I moved my mouse to all usb ports and it still happens, cant change my IRQ in bios and vista has them all locked out from being changed. I also have my X-fi as far away as possible from my video card. I have no idea whats doing this but i need some help.
Specs are as follows
P5Q-PRO
Q6600 @ 3.48GHZ
4GB Mushkin @ 078
X-fi Extreme Music ***Lastest [email protected]

I've never had pictures of the mod, as it is it wouldn't show up vey well in a photograph, not to mention that every front panel board is different from one manufacturer to another. Mine came with my Gigabyte Aurora case, but Gigabyte probably didn't manufacture the circuit board itself.
I had the noise problem when I first tried out my new Bose headphones with it and knew I needed to fix it. The main issue is the metal mounting studs that attach the board to the case front cause a ground loop with the grounds coming in from the sound card, as well as the motherboard USB headers. Having all these grounds just connected together like that is the root of the problem. By far the worst issue is the studs being connected to the foils on the board. Scraping the foil off the board where it makes contact with the studs will probably fix most of the noise. Next, cutting a gap in the foils between the incoming grounds from the sound card and USB headers will clean up more noise. If properly done, and all plugs removed from their headers, there will be an OPEN connection between any one ground wire and another, as well as there will be an OPEN between the chassis (case) and any of the ground wires. The ground wires coming from the headers should show a good connection to their appropriate socket ground on the front panel, but again, an OPEN between each other.

High pitch ringing when recording voiceover

I just started getting a ringing when recording voiceovers. Any idea why?

I am using a Blue Snowball mic. I am also using Sony MDR-7502 headphones. There is a constant high pitch ringing.
In the past I've done voiceovers in FCP with this mic and no headphones without any problems. Since I tried to use the headphones (I bought them today) I'm getting the what I guess is feedback. Even when I unplug the headphones and plug the speakers in, as in previous set up, I am continuing to get feedback. (if this is feedback). This didnt happen before.
Any ideas? I've tried monitor on and off. Turned off my external hard drive. Checked automatic level control. I cant figure this out. I am new to setting up an evironment for recording other than my previous set up so maybe its something basic. You mentioned doorbells and phones. Does that mean nothing metal near the computer such nail clippers or hard drive? Do I need a shockmount? Is that the problem?

Pitch change when recording audio

Hi all,
I've been recording audio voiceover tracks without issue for 3 years to my Mac Pro:
OSX 10.9.2
2x2.3 GHz Quad-Core Intel Xeon
12 GB 106 MHz DDR3
I record with a condenser mic via my M-Audio FastTrack Pro. Suddenly, all recorded audio now has shifted up in pitch to chipmunk-like frequencies and I cannot figure out why. As far as I can tell, the duration of the clips does not change, only the pitch. No settings have been changed in FCP X or on the FastTrack Pro. Has anyone else had the same problem or know of a fix?
Thanks,
Bill

is there a time limit in GB
Yes, though it shouldn't change the pitch or speed, it would jsut cut off.

Low pitch hum when recording audio with iOS 7.1.2

I recently updated my ipad OS and now when I record I get a low pitch hum. I have checked all of my cables and connections, I've tried out different pre-amps (alesis iodock and focusrite scarlett 18i8) and I can not get rid of the hum... When I hook the pre-amps up to my pc the sound is crystal clear. Any suggestions? I've tried looking for firmware updates but none are posted as of yet.

Noise when recording through new sm58 mic

Hi there
Just got an Sm58 to replace my crappy old mic. I have it plugged into a behringer ub502, which is in turn plugged into imic, and then into my Titanium PB G4 for recording using GB 3. The sound is great but there is noise, every time I record. It's like a crack or pop that comes sometimes every couple of seconds and sometimes every ten seconds or so. It's impossible to enjoy listening to anything with this noise, and I am having no luck getting rid of it. Any suggestions would be greatly appreciated!!
Thanks in advance
dajama

Sorry, Dajama, I read a lot of threads here. I had seen your post mentioning the thing that shall not be mentioned and associated it with a different thread. An interface of some sort is obviously required, and the iMic, unless it's defective, should work fine with your set up (I used one myself a while back)
There were some lengthy discussions about USB interfaces and clicks and pops in the GB2 forum last year, but a common denominator was never found. I experienced it only once myself, and did not have a USB interface hooked up (only a USB keyboard, which could have been a common denominator, except I never saw the problem again after that single incident)
Sorry I don't have a useful suggestion B-(>

Logic 7 audio playing high pitched noise

Hi Discussion Group.
I am having some major difficulties with LP7.0.1 (downgraded frrom 7.2.2 and was working fine with 7.2.2) and the motu 828 mkII that just crept up on his system today.
An audible high pitched noise when playing logic after initially starting 10 seconds after first play. Also after stopping playback the high pitched sound lingers.
Logic complains of sync problems between audio and MIDI.
All music is heard fine with iTunes. there is no other audio software playing at the time of logic playback.
Nothing has changed on his system to create this. before today everything was working fine. We removed everything from the firewire bus and only the MOTU is present.
playing logic fine out the built-in audio just fine.
Changing the clock mode to autosync does not help and iTunes stops working. internal works fine. Also setting the I/O buffer size to 32, 64, 128, 256, and 512 and relaunching the driver each time did not help.
no MIDI card
Here are screen shots of his MOTU control panel and Logic Audio Drivers preferences
http://www.enabled.com/~noah/MOTU/
Any clues on what else to try? I am at a loss here.
cheers,
Noah

I've heard of weird things like this happening to 828's before.
There is a reset procedure, either in the manual or on the Motu website - try running that and seeing whether it fixes it.
