Feedback noise from microphone

I have an HP Pavilion desktop p6674y. I plugged in the microphone on the rear panel. The microphone works and I can record with it. But the feedback noise that comes through the logitek speakers makes it impossible hear the audio recorded over the noise. How can I eliminate the feedback noise?.

Feedback noise from iOS4 upgrade to 3GS

Dear Apple marketing folks, we appreciate your developers, but please get us a patch for this iOS4 issue ASAP. Think of the bad (and very public) experiences that are now happening daily with iPhones randomly making loud screeching noises in work places, cafes, buses, subways, etc.. Talk about bad word-of-mouth marketing. Ouch. The Android marketing people are going to have a field day with this one if it does not get fixed quick.
The recent upgrade to iOS4 on my otherwise great 3GS is causing random, loud, high-pitched, feedback noises to emit every time the phone makes a noise for anything else (reminder ding, etc).
A phone call with tech support only got me a suggestion to do a Restore via iTunes and confirmation that they know this is trending up. The Restore did not work.
Other threads listing the same issue:

5. http://bit.ly/bTxsBT
Lots of blog mentions on the issue just like this one from iLounge: http://bit.ly/eA1rU.

I have had the same issue following my upgrade to iOS4. In my opinion these issues are uncharacteristic of Apple. I have had no issues with this phone or any other Apple product that I have used until I made the upgrade to iOS4. I agree with the other posts that something needs to be done about this (and other iOS4 issue) ASAP. PLEASE post any tricks that you have found (besides restores, and reboots which I have already done without lasting success)to work on a more permanent basis.

Feedback noise from computer speakers

my computers are emitting feedback noises when I turn the volume up. if i plug in headphones, i can hear the tapping of keyboard keys, and anything that's happening inside the computer. What do I do to fix this? Why is this happening?
please help me!

Same problem here!! no matter if speakers or headset is being used the feedback is terrible, even the volume if the mic is automatically turned down ( I guess to avoid the weird sound). the sound hardware checkup only finds that mic detects sound and that speakers make noice so it figures out that sound is ok
any ideas????

Background noise from microphones

Using an iMac G3 with CRT and OS 10.3.9 we are trying to use Skype and getting an overwhelming amount of background noise with and without an external microphone. A connection is made but there is a loud humming sound and our voices are barely audible. Could this be a problem with our high speed sbc connection and phone line filtering? Any ideas are welcome at this point.
Thanks,
B.Ball

You did not mention if you have tray load or slot load iMac. (This refers to the method for loading CDs.) Earlier tray load iMacs have a fan, slot loaders do not. The fan on my tray load Blueberry can be quite loud in my quiet office (although no louder than any other computer fan), and so I am wondering if that might be the source of the background noise.

Removing microphone crackle noise from a video

Hi there,
Please could anyone offer some advice on how to remove a "crackly" noise from my video? The "crackle" appears to have come from the microphone that was clipped to a shirt, and as the speaker moved, the microphone picked up and recorded the scraping noise!
I have had a go with the audio effects in Premiere Elements, but haven't had any luck removing the noise, unless the sound gets distorted. I am new to Premiere Elements but have a gut feeling that I will probably need to re-record the speaker again. I thought I would ask the question, just in case there was some method I haven't found / understand yet.
Thank you

From within PrE, I think that you have gotten good advice. The ability to remove transients from Audio is a bit limited in a video-editor, and can take a lot of experimenting.
There is something a bit better, but requires additional programs to accomplish. Even then, experimenting and critical listening will be needed. The first is an inexpensive, but great audio program, Magix Audio Cleaning Lab. With just the default settings, it does an amazingly good job with such things, though might never be perfect. I then use Adobe Audition, which has a Transient Repair Tool, and must be applied by hand, for each Transient that remains. It is NOT inexpensive, but so very powerful. This ARTICLE will give you a bit more info, plus a link to the Magix program.
Also, I would check out what is inducing the crackle into the audio stream. Usually, this is because of a bad connection in the chain. Fixing things there, is the best course, for the future.
Good luck,
Hunt

Flex 2 - Persistent Feedback Noise

Hi everyone,
I've had my Flex 2 since about December and ever since I opened it there has been this recurring high-pitched feedback noise emitting from the computer whether I'm running things on it or it is simply idle (i.e. at the desktop). It is also persistent whether the laptop is charging or on battery power. Anyways, I sent it in to Lenovo about a week after opening the laptop and they sent it back saying the issue had been repaired with the motherboard being the cause of the issue. As soon as I turned on my laptop, the noise was still there. However because I needed it for school, I couldn't send it back in til Spring break. They then contacted me saying that they couldn't identify the problem I had stated and even after describing to them in detail the issue, they could not identify the problem. At this point, I needed my computer back for the new school quarter and so had to request that they return my computer to me "unrepaired". The feedback noise is still persistent and annoying as ever but it seems I'm out of luck with trying to get Lenovo to help me with this issue. Has anyone else dealt with this problem? Also, the noise comes on and stays on whenever I go to configure the microphone properties in control panel. As soon as I close out of that, the noise switches back to being an on-and-off noise.

No proper fix. Workaround is to uninstall the Realtek driver and use the generic Windows driver.

Internal speaker feedback to internal microphone

Our PowerBook G4 recently started to emit loud high pitch noise from the left speaker when one puts one's hand just above it or when playing i-tunes above mid-volume. It did not previously do this; not sure if it started after we did a software upgrade. It sounds like feedback from the internal microphone to that side speaker. This seems to be confirmed by plugging in an external speaker which causes the noise to stop. Can this be fixed? How does one turn the internal microphone off?

Unfortunately I have already been to the Sound control panel. Reducing the input level to the minimum is not low enough to prevent feedback once the speaker volume is above about 60%. As for switching to "Line-in" the option does not exist, the only option is "Internal microphone". However, I am quite certain that once upon a time that option existed. Again my most likely suspects are either an OS (10.5.8) or iTunes (9.2.1) software update, a hardware problem with the input jack (perhaps it disliked the impedance of a standard 3.5 mm TRS stereo plug microphone I tried to use), or a setting of the Audacity (1.2.1) sound recording software which I was experimenting with, which has removed the "Line-in" option from the Sound control panel.

Playing sound from microphone on speakers (through buffer) with constant delay

Hi,
I'm looking for an example of code that samples signal from microphone and
plays it on speakers. I need a solution that has a resonably constant delay on
different platforms (PC, android, iphone). Delay around 1-2 s is ok for me, and I don't
mind if it varies everytime the application starts.
I tried using SampleDataEvent.SAMPLE_DATA event on Sound and Microphpne classess.
One event would put data into buffer the other would read data.
But it seems impossible to provide constant delay, either the delay grows constantly or
it gets lower to the point where I have less than 2048 samples to put out and Sound class stops
generating SampleDataEvent.SAMPLE_DATA events.
I wan't to process each incoming frame so using setLoopBack(true) is not an option.
ps This is more a problem on Android devices than on PC. Althought when I start to resize application
window on PC delay starts to grow also.
Please help.

Most recording applications have a passthrough option so you can listen as you record. It is off by default to avoid feedback if you are using a microphone.

Can Logic plug ins remove background noise from interview?

Can Logic plug ins remove background noise from interview?
A friend with an important interview recorded in noisy conditions has asked me to help remove background noise - never done this technically.
Is there a Logic or third party plug in that would could remove background noise from a spoken word interview? Have tried EQ which improves the sound slightly but not a solution.
Anyone with specialised knowledge of this sound editing operation?
cheers

There are several 3rd party denoisers, they mostly work by first 'learning' the noise footprint of the audio, for which it is best to record a few seconds of silence (with an open mic).
These will all do a decent to excellent (it all depends on the source material) job:
http://www.kvraudio.com/get/3199.html
http://www.kvraudio.com/get/2104.html
http://www.kvraudio.com/get/2791.html
http://www.kvraudio.com/get/1182.html
http://www.kvraudio.com/get/1029.html
Addit:
Is it that background noise (traffic, talking etc) drowns out the words? Then you'd probably have more luck with (radical) eq-ing and/or notch filtering to find the most dominant frequency range of the speaker in relation to the background noise.
As an interviewer myself I will point out that even with a small disctaphone you need to have some awareness of how the microphone picks up things. As soon as you nead to lean towards whoever you're talking to, just to make sure you're audible, the dictaphone on the table is probably recording mainly ambient noise, the interview being part of that. This is especially a problem when interviewing in a busy public space.

Qosmio G20: constantly noise from left speaker when webcam mic enabled

Hi,
Has anyone successfully installed the logitech quickcam 5000 on their Qosmio G20? I can only use it with the microphone disabled - enabling it results in constant 'noise' from the left speaker (or earpiece).
It would be nice to get this working...
thanks in advance,
Aiden

Speakers getting a feedback noise.

I have a set of BOSE Companion 2 series speakers, I keep on hearing a feedback every so often. I was trying to find the solution, but I can't. I have them hooked up in the Headphone/speaker jack on my new I-Mac 20" 2 GHz Intel Core 2 Duo. I also have a Belkin USB Lighted Hub with a Western Digital usb external Hard Drive. I just don't want to ruin my new I-mac with some sort of power surge, or is this normal. Can some one give advice?

Sorry I was typing the question up and posted it in the wrong spot. I believe I have figured it out.
I have unplugged the speakers from the computer, but left them plugged into the wall plug. They still made the feedback noise. I am guessing it has to be from a different source or the speakers are faulty. I have never had a problem with any other speakers, so I was thinking it might be them.

Nokia 6300 high pitched whistling feedback noise d...

I am now on my fourth Nokia 6300 having returned the previous three because of the same high pitched whistling or feedback noise during a call. I have also tried updating my SIM card (a genius at Vodafone came up with that idea) and still the same problem.
I know of a couple of people with the same phone and no problems, so I can only suppose it is something to do with the Vodafone software.
I would be happy to try updating or re-loading the software but cannot find it anywhere?
I really like everything else about this phone so any helpful suggestions would be appreciated!

I also recently upgraded my wonderful 6233 with a 6300. The ear-piece of the first one I got produced a constant buzz during calls. Returned it, got a new one on the spot. After a few days, I started having complaints about my audio at the other end; the symptom was a very high noise level (coming from my end) together with echo (the caller would hear their voice echoed back). I had also started noticing a distorted low-level replica of my own voice present at the ear-piece. The first thing that came to mind was "oh no, another replacement!". Being a bit of an inquisitive mind though, I decided to debug this a bid further. So I browsed the web, and among other things came across this thread. The turning point was correlating the problem with reports of Bluetooth incompatibility from various users right and left; as it turns out, the 6300 appears to have a serious Bluetooth "problem". To make a long story short, the situation is as follows. After the phone is turned on, all is well: audio at the other end is perfect (no noise, no echo). Then I turn on my Motorola H700 head-set. Call the phone from a land-line, and yes, the noise level is high as hell; the mic gain is turned up so much that you can whisper a couple of meters away and hear yourself just fine on the other end! Here comes the catch: turn off the Bluetooth head-set, and surprise-surprise, the problem is still there with the built-in mic; turning off and on the phone cures it. But wait, this doesn't happen always. Sometimes the mic level goes back to what it was before, and the phone is working fine once more, without power-cycling.
That's more or less it; I hope it rings a bell with someone reading these lines, and hopefully it gets fixed in a future firmware revision. In the meantime, I need a new Bluetooth head-set...

Everytime my phone vibrates it makes this loud noise from inside that sounds like a weird cracking noise or something help!!

Okay so I noticed a week or two ago that there was something lose on the inside of my iPhone 5s and ever since then when my phone vibrates sometimes there is this weird noise. It sounds almost like a cracking noise from the inside or a weird electrical noise. I think something is wrong with the vibrating part. Does anyone know if this is fixable or what it is?

Hello ashliz17,
After reviewing your post, it sounds like the phone makes a cracking noise when it vibrates. I would recommend that you read these articles, they may be helpful in troubleshooting your issue.

Noise from hard disk

Hi, everyone.
I bought a new mackbook pro in this Jan. Recently, I hear some not continuously noise from hard disk, especially when i open a file in hard disk or verify the hard disk. Is something wrong with my hard disk?
Thanks

This hard disk clicking is a know problem for many laptops. If you search it on Google, you will find a lot of discussions about it in the Unbuntu Linux forums. In most cases, it is due to the Advanced Power Management (APM) feature of notebook hard drives. The default APM settings of these drives are aggressive so as to extend notebook battery life. As a consequence, the HD tries to park its actuator head to the ramp whenever it judges the system as idle. However, OS X or some third-party applications may access the hard disk quite often, resulting in a park/unpark cycle every few seconds.
Every of these cycles is counted as one load/unload cycle. Most notebook drives support up to 600,000 load/unload cycles. If a hard drive parks its head every few seconds, it may shorten its life by "using up" the cycles more quickly.
I had the same problem on my Powerbook with a Hitachi Travelstar 5K160 80GB PATA drive. I heard the frequent clicking sound right after I installed it into the laptop. The SMART status appeared to be Verified, and there was no problem with the drive itself. After searching on Google and Hitachi web site, I found the causes and solved the problem using the Hitachi Feature Tool. For other HD brands, I have no experience at all.
Basically, Travelstar 5K160 drives have three idle modes, from which a user can set one as the deepest idle state:
1) Active Idle: the actuator head is parked near the center of the disk, and power usage is 45-55% less than performance level. Recovery time to active mode is about 20ms.
2) Low Power Idle: this is usually the factory default idle mode. The head is UNLOADED to the ramp and the power consumption is 60-65% less than the performance level. Recovery time is about 300ms.
3) Low RPM idle: in this idle mode, the hard disk will spin down to a lower RPM speed. More power is saved but recovery time is much longer. (I can hear the disk spin down and spin up again a few times per minute. There is also a lag in system reaction time.)
To get rid of the hard disk clicking, you need to set Active Idle as the deepest APM idle mode. To do it on a Hitachi hard disk, you need Hitachi Feature Tool, and a Windows laptop with the same HD interface as your drive (PATA or SATA). Sadly, the feature tool is only for Windows and Linux.
You can download Hitachi Feature Tool 2.10 as an ISO image here: http://www.hitachigst.com/hdd/support/download.htm#FeatureTool and burn it into a bootable CD. The userguide of the tool is available on the same page.
Then, take out your hard drive from your Macbook and install it into a Windows laptop. Boot the machine using the Feature Tool bootable CD. Choose "Change Advanced Power Mode" from the drop-down menu.
The default value is 128 (Low Power Idle). Just increase the value toward Performance, until you see the APM mode over the value bar becomes Active Idle (starting from 192). Click OK and Exit the feature tool. Switch off the Windows laptop and take out the hard disk. Install it into your Macbook. You will not hear the clicking sound again when system is idle. The lowest APM mode will be Active Idle and hence the drive will not park its head to the ramp during operions.
If your hard drive is a Hitachi Travelstar 5K160, you can find the 5K160 specifications version 1.1 from Hitachi web site. On page 69 of the document, it explains the APM idle modes. On page 145 about the register values of the APM modes.
To set Active Idle as the deepest idle mode may adversely affect battery life. (I haven't yet tested it myself) However, there seem not to be a big difference than the Low Power Idle, according to the datasheet of 5K160. For this model, power consumption of Active Idle is 0.8W, while that of Low Power Idle is 0.6W, on average.
Hope this is helpful.

"Squelchy" noise from external speakers plugged into headphone jack

I get a strange, warmly, high pitched static continuous "squelchy" noise from my external powered speakers when I have them plugged in via cable to the headphone jack of my iPad (3rd gen). The noise occurs only with the iPad - the noise is not present with other devices, such as my iPhone 4S, older iPhone 3G, or my Samsung Galaxy or Toshiba Thriven (both Android devices). Also, the noise is present only with external speakers - never with headphones. Doesn't happen with Bluetooth audio.
The pitch of the squelchy noise seems to be related to how much load the iPad processor is under, though I can't say for sure. I honestly have no idea why it's making this noise. I thought it might be a ground loop issue which occurred only when I had external powered speakers plugged in while the iPad was also plugged in, but the noise happens when the iPad is running on battery, as well.
Does anyone have any ideas how I might get rid of this noise?

I don't know if this could be your problem, but...
On some systems the BIOS will sometimes disable the on-board audio controller at startup if it doesn't detect anything connected to the inputs or outputs (older HP computers did this to me ). You usually need to enter the BIOS and permanently enable the On-board Audio by changing the setting from 'Auto Detect' to 'Enabled'.
Hope that helps.
