High pitch noise in CS4 and CS5.5

Hello.
Firstly I want to say that yes I know people have asked this question before but as far as I can tell none of them have been solved. Some have somewhat useful answers but none of them truely solve the problem. This thread in particular probably has the most information about the problem I'm having http://forums.adobe.com/message/4298535#4298535
I recently tried Premiere Pro CS5.5 and CS4 (trial version) to replace my Corel Video Studio X6 which tried to replace Windows Movie Maker. Video Studio and Movie Maker both crash whenever I imported large video files.
Anyway I'm getting a problem where the video files I import to Premiere Pro CS4 and CS5.5 have a high pitch noise in the video preview.
It's a high pitch noise almost like it's getting feedback from something. Also when someone is supposed to be talking there's a very low distortion, like the audio started playing in very slow motion but the high pitch noise is still present.
I'll put a link at the end with the video file that's giving me trouble.
The video and audio are in a single AVI file. The video format is H264 shot at 60fps and the audio should be Mpeg-1 L2, 48khz at 320kbps. I don't know if the video's audio is in 24bit or 16bit.
I've tried different settings for premiere. Trying 60fps and 30fps for the framerate for the project. Trying 44khz and 32khz and 96khz didn't fix it. Using the "Desktop" preset in CS4 and Custom for CS5.5.
My audio hardware is a Logitech G930. It's a wireless USB headset with microphone. My motherboard audio is Realtek HD Audio. Both are enabled but I only use the headset now and nothing is being sent to the Realtek audio chip (according to Windows' sound options). The headset plays audio at 16bit 48khz.
The video file plays fine in every media program I own that can play the h264 codec. With the exception of Movie Maker and Video Studio x6. Video Studio will preview the video and audio just fine but when I try and skip around the program hangs and crashes. Movie Maker just plain crashes when I try and import the video. Some of the programs that can play the video are VLC, Media Player 11, and Media Player Classic.
I'm not sure if Final Cut Pro has the same problem. I don't have a Mac so I can't test it.
Here's a sample video that works the way it should. I pulled a BIK file from a game and converted it to H264 in AVI. Not sure what it's audio format is.

Just click the download button at the top right.
Here's an afflicted file. Not the exact specific file I have been talking about, but it has the same codecs. This one is shorter in length and smaller in size. It still has the high pitch noise, but since there is no one talking in this you don't hear the weird low pitch distortions.

Thanks.

>single AVI file. The video format is H264
H.264 will not work inside an AVI wrapper http://forums.adobe.com/thread/854115
-Insignia camera uses H.264 to either AVI... SOME to MOV wrapper
-so use the MOV wrapper if YOUR Insignia camera offers that option

As Jim said, not within the design specifications because it is non-standard video

Since Yosemite upgrade, high pitch noise creating case vibration on MacBook Pro (15-inch, Mid 2009) (on watching the keynote online)

Hi,
Great work on Yosemite, great new design as well.
Several problems since the Yosemite upgrade though :
    - When playing high pitch noise (watching the keynote for example), the speakers make the case around it vibrate. This was not happening under Mavericks and previous OSXs.
    - This page (post editing) does not allow the right click (works everywhere else as far as I'm aware).
    - when changing the volume, I have now the noise feedback when clicking on shift+volume up/down and no sound when clicking on volume up/down on my keyboard (was the inverse before).
    - The keyboard light was stuck in off, had to restart the computer.
More general problems (covering the last OSX since introduction of 10.9) :
    - lack of possibility of choosing for a 3x3 set of desktops as it was before (the new mission control only allow us to have a horizontal set of several desktops)
    - Notifications cannot be turned off automatically when being in full screen. (only options for auto turn off given are "display is sleeping" oO and when "mirroring on another display" -> meh, would have prefer when having an app in full screen)
System :
MacBook Pro (15-inch, Mid 2009)
Model Identifier: MacBookPro5,3
Processor Name: Intel Core 2 Duo
Processor Speed: 2.66 GHz
Memory: 8 GB
Bus Speed: 1.07 GHz
Boot ROM Version: MBP53.00AC.B03
SMC Version (system): 1.48f2

Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

On my iphone 4s I got a scratch on it,then about a month later there are verticle lines and a high pitch noise til it is done focusing. What's wrong with my phone?

Hello
Okay so I have had my Iphone for almost an entire year and there's a problem. I have gotten a scratch a scratch about a month ago on the back camera. It's at the very bottom. I've gotten used to it so it doesn't bother me. Well ever since like a week ago my camera gets colorful lines that are verticle and go away when it's focused. Not to mention the high pitch noise while it focuses with the lines. I'm getting irritated with it. Mainly what's is wrong with my phone?! Also how much is the cost?

Since we can't examine your phone, we really have no idea what is wrong. Why don't you make an appointment at your local Genius Bar and get the phone examined and what your options are moving forward.

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.

EMac high pitched noise

Hi. I have a 1GHZ eMac G4 that I got second hand several months ago. Recently, I've noticed that there is a high pitch noise that it makes when I first turn it on or wake it from sleep. This noise only lasts for a minute or so, but it is very high in pitch. I don't think it is the hard drive because I know what a failing hard drive sounds like, but I can't be sure. Could it possibly be a capacitor problem? Does anyone know of this issue and how I could get it resolved? Thanks.

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.
Sorry to my poor English(I live in Seoul, Korea)

A215-7422 Audio Issue: High-pitched noise

About 2 weeks ago, the audio would suddenly stop. After restarting the laptop, it would work fine again. This morning, however, the audio completely died. Restarting it only gave me a low frequency click upon start up. Updating the drivers and the system only made the laptop give off a high-pitched noise through the speakers that persists through turning the volumn down/off and plugging in headphones, on top of which it continues not to play an audio.

A quick update if it helps: I went in a disabled "High Definition Audio Device" and the high pitched noise from the speakers stopped. Not sure if that helps anyone.

N95 - High pitch noise (hiss) and GPS struggling t...

Hi Guys.
Since I bought my N95 I can hear a hiss even when I'm not on call (all the time) and I bought Nokia Maps Navigation and it just worked once (a fews minutes after I bought this service). Now it's not working anymore (I've paid for 1 month service and it worked for a few minutes)...
Are those common issues? I read someone complaining about a high pitch noise (and saying that he had to change his phone more than once so it finally was replaced for a non-faulty one).
Any help appreciated...
Regards,
Daniel

I do not know, people just get unlucky, I think. As I said, mine has had no problems whatsoever since I bought it in April. None at all. No noise (yes, no noise at all) no flimsy slider, no problems with GPS, nothing.

Check where yours is made in.
I must dissagree with you .. Mine is Made in Finland .. it came in grey box .. not the white one .... Mine has High pitch noise .... And about the High Pitch Noise you should know that not all ppl can hear it .. I have some friends that do not hear it at all .. others can hear it only with one of the ears .. others .. like me can hear it loud and clear ....
Perheps I should damage my hearing so I will not be able to hear this annoying high pitch noise
Well, my hearing is fine! I honestly do not have any high pitch noise or anything. I gave the phone to 7 of my friends and they could not hear anything either. I do not know, perhaps you got unlucky. But you are one of the very few with a phone made in Finland that I am aware of having troubles...

Anyone ever hear a loud high pitch noise

For the past week, I have heard a high pitched noise from my imac. It usually occurs when viewing videos and will go away once computer is shut off. It does ring when booting back up then goes away until a video or song is being played on the computer. Apple Support told me it wasn't something they could fix because the noise was heard during reboot. Any ideas? Thanks

Please describe "loud"... I hear once in a while a clicking noise that I know is coming from the hard drive while there is a lot of activity. It is noticeable, but I wouldn't say it's loud. My MacBook Pro does the same thing and at some point I was concerned but I found out that these noises are "normal" during a lot of disk activity.
I would still call or bring it to an Apple service store like the above suggestion, just in case! If you don't live near a store, maybe they will be willing to hear the noise over the phone? Just a thought.

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:
