High Pitched ringing from Zen Mi

I have had my Zen Micro for about two weeks and I have noticed that there is a high pitched noise that emanates from the Zen when I listen to the first 20 seconds of a song. Does anyone know how I can fix this problem without having to send in my player for repair. Thanks in advance.

I believe the ringing noise referred to is transient RF interference caused by the aft section of the player amplifier circuits as they amplify the converted audio signal before it heads out the headphone output. There may be a grounding issue to the circuitboard in the player, as running the backlight seems to temporarily cancel this noise out. I have never encountered a noise that starts when the audio file is started only to disappear 5 to 20 seconds later, only a noise that breaks in on the audio signal once the backlight goes out.
Transient noise may be a symptom of HDD operation on HDD-based players. I have never encountered noise issues with solid-state players such as the RIO or the Sony key-series. Sadly, if this so there can be no cure. Some persons may not notice such high-pitched noise and some persons may find they are quite sensiti've to it. That's how it goes.
I have found that Creative's earphones seem to filter out most of the noise due to a frequency range that is just not as high as competitor products. Creative may have deliberately engineered this range to its products, or they might have simply thought that too much high-frequency noise coming through little tiny earbuds is just not too good for the ears. This is not an uncommon design philosophy.

How can I remove high-pitched distortion from voice-over?

Hi folks,
I'm completely new to fixing audio. I am making a short film, and for a voice-over, I recently had to do an interview over the phone (the subject lives in a very remote location). Actually, I used GoToMeeting, we called into the conference call feature from our phones, and I recorded the meeting into a wmv file. Then I re-encoded it using Expression Encoder so I could pull it into Adobe Audition.
I am attaching a short phrase (extracted as a .wav file) from the interview in the hope that someone can tell me how to improve the quality of the sound. I have Adobe Premiere Pro and Adobe Audition, both CS6 and CC versions.

1. Can anyone tell me, please, how to get rid of the high-pitched "ringing" kind of distortion that we hear on each of her loudest syllables? Also, does this particular type of distortion have a name? I kept finding articles on fixing sound, but wasn't sure what I'm dealing with here, so I wasn't sure which techniques were likely to work. Tried a bunch, and the overall sound got better, but so far nothing has fixed that high-pitched distortion.
2. After getting rid of that ringing distortion, what are your recommendations for making the voice recording sound as rich, smooth and full as possible? In real life, this woman has a BEAUTIFUL, rich voice. But the recording sounds like a flat telephone call (because it is).
Thanks in advance,
Mary

Well, I don't think there's any miracles to be had here. As you say, it's a telephone call and I fear that, since phone lines filter out anything above about 4k, there's no way of replacing it.
I had a look at your file in spectral view and you can clearly see the original material going, as expected, up to about 4 kilohertz--but, above that, there's a generalised area of noise. My suspicion--and it's only a suspicion--is that during your double conversions (to wmv then through a third party app to something else) one of them has added the extra noise as it your original was full bandwidth.
Anyhow, best I could do was use the Marquee tool in Spectral View, draw a rectangle around the upper area (you can see a clear boundary between the programme content and the random extra frequencies) then just delete everything above just over 4 khz then delete.
As for making a phone call sound full and rich, if there was a way to do it, when I was working in TV we could have saved hundreds of thousands a year by using phones instead of far more expensive circuits!

Sony Bravia high pitched ringing

I just bought a brand new Sony Bravia 32' model KDL32EX500 yesterday and everything appeared to be in working order except for a very high pitched ringing sound that comes from the television. I figured this was normal as it is powered on, but it also continues to make this high pitched noise while in standby mode. I researched this a bit online and found this to not be normal at all. I was just wondering what I would be able to do about this or if there is a possible way to fix it. After unplugging the television from the outlet after every use, the noise goes away after several seconds, but I'd hate to have to do that all the time. Any help would be greatly appreciated. Thank you.

I had this same problem while video chatting. I think it has to do with the sound being echoed through the speakers. For example, if I said hi, my friend can hear it, her mic picks it up, it comes back through my speakers my mic picks it up, goes back to her.. etc.
Simple solution, use head phones when talking. As soon as everyone in my chat plugged our ipod headphones into our computer the problem disappeared.
Hope this helps!

Pre has a high pitched ringing noise while on touchstone

Every time I set my Pre on the touchstone, the second it starts charging it has this high pitched ringing noise, like the kind older people lose the ability to hear. Is there any way I can get this to quit?
Post relates to: Pre p100eww (Sprint)

Same problem here. At first I thought it was the touchstone, but it seems like it is coming straight from the Pre. Turning down the volume on the speaker does nothing. Turning up the volume works though - when you are playing music! ;-)

High pitch ringing sound when i plug my headphones in.

Hi
I am currently using a Macbook Pro 15" retina display
There has been no problems previously. Out of no where, today my headphones has this high pitched ringing sound whenever i plug it in.
The audio is fine when I do not use any headphones. but when i plug them in, there is a ringing sound. This is happens as well when i plug in other headphones I have.
I have tried going to Sound under System Preferences and adjusting the stuff there but nothing seems to work.
This ringing sound makes listening to anything unbearable.
Please help

There is a micro switch inside the socket to switch between the optical output (digtal), headphones and internal speakers. It sometimes gets stuck.
Push the headphone plug into the socket numereous times and see if it frees the switch. Please do not push other foreigh objects into the socket as you may break the switch and/or the electrical contacts.

No firewire while high pitched ring is happening

I have a Dual 2.3GhZ G5 powermac tower. When it first starts up theres a very high pitched ring, almost not noticeable, the ring eventually goes away after warming up between 2-4 hours. While this ring is happening my 2 firewire ports will not work. If I open an application of the computer has to do "some work" the ring cuts in and out but then eventually comes back.
Now its happening no matter how long the computer warms up (even days).
The rest of the computer functions fine aside form no firewire devices showing up.
Any thoughts????

Hi uertzjl, and a warm welcome to the forums!
Tough to tell what the "ring" sound might actually be, but the symptoms sound like a problem with the Power Supply.

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?

Bizarre High-pitched noise from K8N-NEO *I have read the other posts*

Hello.
I just got a new system to build, but it has decided to pee in my Wheaties.
Here are the specs:
MSI Neo Platinum
Nvidia 6800 video
Athlon64 3200
Kingston Hyperx PC3200
Antec Tru430 - 430watt
+5 +12 +3
36A 26A 28A
The board, CPU, memory, and video are installed in a new Antec case. The CPU is installed properly and I am using some ArticSilver 5 paste.
When the board posts, I hear a horribly loud and high pitched squeal. It sounds like a smoke detector going off.
I have read a number of posts regarding loud noise from the MOSFETS or from a loose chipset heatsink or as a result of a poor power supply. I think that this power supply should be adequate and the noise seems to be too loud to be a result of a loose component.
The board appears to go through the post procedure and stops on the "processor initialization" stage. After about 2 seconds of being powered on the video fans stops spinning. The HS Fan (which is the one that came with the retail package) does not appear to be spinning at full speed, neither is it running too slowly. As a result, I have not put power to the board for more than a few seconds (fear of heat damage, though the HS never gets warm...)
I am at a loss here. I have reseated everything several times, if this is a defective board then I am really irritated that it would pass QA and be sold. Any suggestions that you could provide will be greatly appreciated. If you prefer you can send me an email at [email protected]
Thanks again!
Moe

Cheers !

High Pitched Sound from X61 -- sent in for repair

So, since the very beginning of my Lenovo Thinkpad ownership I have experienced a high pitched noise when on High Performance battery power.
So I just switched it to Power Saver mode and forgot about it (Busy student, hard to find time to go weeks without computer)
So recently I sent it in to Lenovo. They replaced the motherboard and the hdd.
I recieved it today, only to find that it is still quite prevalent.
I'm wondering how many have went through the repair service for the same problem. Also, do they at the repair center just put parts in and hope it fixes it without checking?
I called and they told me it will be on escalated priority (has anyone ever been told this?) and the box will get here tomrw. Thankfully I live in Memphis where a repair center is right around the corner. (However, I go back to school the 14th)
They told me they will be replacing the fan. I'm no expert, but it doesn't sound like the fan. What can I expect from lenovo if they can't fix this problem?
Thanks,
Josh

High pitched whine from netbook when power is plugged in. Does not charge when computer is on.

I have a specific power / charging issue On HP Mini Netbook 210-1077CA. Windows 7 starter ( I think)
With the computer OFF ...
When I plug in the power it gives a high pitched whine. Red battery light is on, showing it is charging. (computer is off.)
To test the computer I have turned in on after charging for a little while and the % of charge is increasing. Showing that it is charging properly.
HOWEVER,
With the computer ON
The battery light turns white and does not stay on, but flashes periodically. Its not a constant flash but a pause of several seconds between a series of flashes. The manual indicates a Flashing Battery light seems to indicate either going into a sleep mode because there is not enough battery power (however my power is at 14% normally this happens I think at 10%) OR as the manual indicates there is a problem with the battery.
I removed battery, removed power plug and then pushed power button holding for 15 seconds. No change in behaviour.
I also tried to boot the computer with just the power plug in and no battery. But it would not turn on. I don't know if that is normal or not?? Interestingly the White battery light, while trying to turn the computer on without the battery stayed white no flash. (but did not turn on either as I mentioned.)
I read a few posts that say that the whining are Capacitors doing some sort of harmonics. Although I have never heard this sound before.
Im sure that this problem is not fans or heat sinks etc. Since in only happens when the computer is off and charging. In my opinion its definitely electrical. The sound seems to be coming from the center of the netbook or the battery area..
So my conclusion is ...
1. Battery has problem and needs to be replace,
2. Maybe the AC adapter is bad, since it doesnt boot w/out battery (if it is suppose to ??) Also since it seems when I turn it on it goes from Red charging to white flashing as soon as it starts to boot. Could it be the AC adapter is not giving out enough power to charge and to boot at the same time.
Anyway can anyone help me on this issue. Im not sure whether to start by getting a new AC adapter or new battery. I would not like to buy new both and just throw money at it.
Maybe it is not either???
You help would be appreciated.
Regards.

I have resolved the problem.
I replaced the AC adapter. Everying works find now. I tested runing the computer without the battery, and it works. So I might add that a possible test for an adapter that is not functioning properly is to try running it w/out the battery. If it does not run its possible that the ac adapter does not work.
Thanks.

High Pitch Sound from iMac '11?

Hello everyone,
I purchased the mid '11 iMac model and am now hearing a high pitch sound which fluctuates when I change the screen brightness.
Is this a known problem; is it big enough of a problem that Apple will fix when still under warranty?

You shouldn't be hearing a high pitch sound. You should take the iMac in for evaluation, but first verify that you don't have another other equipment attached that might be contributing to the issue. My recommendation is to try disconnecting the iMac from any surge strips or backup power (UPS) supplies to see whether the issue still occurs. I would also disconnect any external peripherals, USB/FW devices, speakers or audio equipment that you have attached.

A high-pitch whine from a KM2M?

OK, this is REALLY upsetting me and I figure someone out there might be able to help.
I bought a KM2M combo motherboard from a local computer shop about 3 months ago. I was using an AMD XP 1900+ w/ 192 megs of pc-133 memory.
Well, I upgraded a few things and here's my current list in my rig:
KM2M Combo mobo
AMD Athlon XP 1900+
Cables Unlimited Super Quiet "whisper" cooler w/ copper core (it dropped my cpu down from 104F to 84F!!!)
8x AGP PNY Nvidia GeForce 5200 Ultra w 128 megs ddr memory
512 megs(2x 256) Paired ULTRA DDR pc2700 dual-channel memory
92.6 Gigabyte Hitachi Deskstar ATA-133 hard drive with hard drive cooler attached
8x Lite-On DVD-+R/W drive
2 80mm high-flow Speeze brand case fans
300 watt ULTRA Power Supply w 2 blue LED 80mm cooling fans
Scorpion see-through yellow IDE & Floppy cables
Well, after a few changes, my mobo starts to make this REALLY high-pitched whine! Well I thought it might be the PSU or heatsink, so I go through EVERYTHING and NOTHING is making this sound! I even tried changing memory & power settings in the BIOS, but no luck.
Well I set up this exact setup on a chaintech mobo and I get NO shrill sound whatsoever! (proof it isn't something outside of the mobo)
Any ideas on how I can fix this? I would take it back to the computer store & get it replaced but my dog chewed up the box it came in a few weeks back so I can't take it in to get it switched out...

That is a fine set of stuff you have. The PSU also has a fine name, but what ampères does it give on 3.3, 5 and 12 volt? Try to localize the sound, for example by holding your hand to a device - not a fan! - and see if it is a bit loose, cause it sounds like something is loose, the Northbridge heatsink or a capcitatior, as you say.
Elsewhy, follow the thrilling development in the thread suggested by Osnavi.

High Pitch ring/ B

Hi guys, i've been reading alot of issues with the x-fi and nf4. So i figured i see if anyone if familiar with this before i try creatives imfamous tech support. Anyways i am quite computer literate and understand whats going on. Now for my issue, at random times during games, specifically Company of Heroes, Underground 2, Star Wars Empire at War the sound will screetch a high ping ring and stay that way. So loud that i have to turn my speakers off. It only goes away when i restart the comp. Now i have SLI, I turned it off in COH and it seemed to go away for now, but that defeats the prupose of having sli lol. But the other games seem to have some issue or another relating to this. I didnt think this qualifies and the crackling problem i've heard alot about this seems different. FYI onbaord sound works fine. Now i have no other pci card, just the sound blaster but it does share an irq with one of my video cards, asus said thats how the pci bus works on the newier boards (kinda baffled me). Newiest bios, newiest drivers blah blah no rookie stuff. All other onboard devices are off PCI Lat at 64. Now for my specs
Asus p5n32-sli se (nf4)
Intel core 2 duo e6600
2xg corsair xms pc6400 5-5-5-2 The stock timings are 4-4-4-0 i set them high just incase
2x evga 7900gt co's
550watt Antec Trupower

Yeah i also have a p5n32-sli SE with a E6600 and the same memory and PSU but with two 7800gt in sli, and in most games like for example Gothic 3 and Dark messiah of might and magic i also get that problem. Altho in some games it seems more random, like in gothic 3 i can sometimes play for very long times without it happening but in say dark messiah i get it constantly after a pretty short while. And also since that high pitch beep can be muted in windows i would guess its some kind of software problem.
I found these threads with other people having the same problem

but no solution, altho some claim disabling SLI will work but as you said that relly isnt an option, id rather use my onboard sound in that case.
I sent a mail to creatives support like a week ago but have yet to get a reply.
The only thing i forgot to try was using the old drivers that came with the card instead of the latest, but i had to pull out the card to find the serial and model numbers when contacting support and i havent bothered putting the card back in so i cant try, but then again i think someone in one of those threads already tried with older drivers and it didnt fix it.
Well , I remeber the days when soundblaster cards were THE cards for gaming but sadly creative seems to have dropped the ball with this series, and sadly seeing all the problems creative are having with these cards and the lack of support even indicating they are working on fixing the isssues , well lets just say i probably wont waste my money on a creative product ever again, after all thats all i can do as a consumer.

High-Pitched Squeaks From Internal Speakers

Hello,
I just received my brand new mbp a few days ago and I noticed a significant difference with sound quality from the internal speakers compared to the previous versions of the mbp.
My new one seems to be giving out really high pitched sounds when I am playing my music. It's really high pitch and it is affecting my work and giving me headaches when i do my work.
Anyone experiencing such problems?
and is there a way i can adjust this or is it a mechanical defect?

Try looking at the previous discussions on the right hand side of this page under the heading "More Like This".

Ipod touch 4 creates high pitch noise from cassette adapter

Did not have this issue with my ipod touch 2nd generation.
Have a Monster cassette adapter in my car (looks to be an earlier model than what is currently for sale at Apple website). ipod touch runs off of battery (not plugged into power source).
Creates a high pitch noise through the speakers. Not particularly loud, but annoying and very noticeable during quiet moments of music/podcasts
Volume of noise does not change with changing the volume on the car audio system.
Will start when the ipod touch starts playing. Will persist as long as the ipod is playing. Will not immediately stop when the music is paused. It will stop though after about 10-15 seconds.
Any ideas of what is causing this and why it did not happen with my previous ipod touch (2nd gen)?
Using iOS 4.1

Thanks for the suggestions/questions
If I plug the touch into my wife's car that uses a straight plug-in (no cassette adapter), I don't hear the noise. Unfortunately this is not an option on my car.
Have not tried plugging it into an actual home stereo but can give that a try.
If the engine is shut off, the noise is still present. Unaffected by the engine or RPM of it.
One other clarification - the noise is constant coming from the ipod. It does not vary based on the ipod volume. What this means is that if I turn up the ipod to full volume (and turn down the volume of the car stereo), the noise is less noticeable.
Of course the noise gets amplified with the rest of the music by the car stereo volume.
Will also try other suggestion and see what happens if I turn Airplane mode on.
Thanks
