Conversion/noises in headphone

Hi,
I have two questions.
1.) How can I convert Logic Pro files into a format that can be read and edited by Cubase on a Windows computer and vice versa? Does Cubase need all of the files connected to the music data?
2.) Whenever I want to record my voice on an Audio track by microphone (external), I hear a noise in my headphones (sounds like wind or waves) when I start to speak or sing. It doesn't matter which kind of voice preferences I choose (male lead, female background chior...). - The noise is not audible when I listen to the take but the are really disturbing. - In the prefs, I chose the Line-In-Microphone, and there is no other mike or any loudspeakers. Any ideas how to solve this problem?
Thanks a lot in advance!
Tomas

If you make a Genius Bar appointment in advance, you should have very little waiting around.

Mighty Mouse causes electrical noise on headphone socket of Intel iMac!

Sorry for posting this again (it was originally a reply to another thread). I just felt it warranted some attention.
Mighty Mouse (and other USB optical mice) cause noise and interference on the headphone port in an Intel Mac!!!
In the other post it was reported that there was discernible electrical noise and interference when using the headphone port, with echoes, pops and a constant buzz and whine. I really noticed this as well, especially after the impressive noise-free headphone output of the Mac mini I had for 10 days before upgrading to an iMac.
I noticed that the noise changed from a buzz to whine when I moved and picked up the mouse. I've got my Mighty Mouse plugged into my keyboard. At first I tried unplugging the keyboard from the iMacs USB port and the noise stopped. Then I plugged it back in, and then removed the mouse from the keyboard. The interference stopped. I then tried plugging the mouse directly into the iMac. Again, that horrid buzzing whining noise and echoes. So it is definitely the mouse!
The noise changes when the mouse's scanning red light switches on and off and during movement.
I've then tried a second Mighty Mouse, the one I bought for my Mac mini. Same thing. And just now I tried another optical mouse, a mini-notebook one. The noise is even worse! It's quite bizarre as well, the noise changes in pitch the further I move it from the desk surface - its like tuning a radio!
Am I going to be reduced to plugging in a clunky old USB ball mouse to avoid noise through the headphone port of my 1 day old iMac? Can you actually still buy such a device?
Actually, can anybody report on whether the Apple wireless Bluetooth mouse causes electrical noise on the headphone port? And is the noise just on the headphone port or on the inbuilt speakers too? And on the headphone port's dual function as optical audio output?
This is not good. And I'm quite surprised it is something that has been missed by Apple's engineers. Or has it? Is this a known problem? Somebody should have words.
Can anybody from Apple comment? Do they frequent this place? I hope so.
20" iMac (Intel) Mac OS X (10.4.5)

Hello, I bought an iMac 20" today and ran into the same problem...and found this conversation (and the original thread) with a search for "iMac headphone jack noisy".
The problem is painfully audible on a pair of Etymotic Research headphones that I have on loan from a friend. These are designed to fit into your ears with earplugs that seal off the rest of outside sound, so it's practically like having an oscilloscope plugged into your head. Though the Mighty Mouse certainly aggravates the problem with the varying pitches of whine, I have to say it's just a noisy jack when compared with other devices I've plugged the headphones into.
For instance, my Powerbook G4 has some noise on the headphone jack but it's a soft hiss. There is no variation introduced by plugging in the mighty mouse.
However, on both the iMac and PowerBook G4 it appears that the electrical gain on the noise in the headphone circuit is completely independent of the volume level. This is not true of the iPod, where if you turn the volume all the way down while no song is playing the jack goes dead quiet. If I'm right that the volume is being done entirely with software on the computers, then I have become curious as to whether there is any way to control the electrical gain of the headphone jack.
Without such a hardware-level gain control in the iMac or G4, then if your headphones don't take much power to drive...the relative volume of the noise will be greater. So you can make this less noticeable with bigger headphones. I can't hear any of this noise when I'm listening on a pair of bulky AKG studio monitors (which are not particularly shabby in terms of frequency response or audio quality, though the maximum listening volume isn't very good without a headphone amplifier).
More expense, and hassle, just to work around a
problem that should have been noticed and rectified
before Apple released these computers to their eager
public.
In Fight Club, the main character faces the grim truth about how his automobile company handles recalls. The financial formula wasn't to recall a car just because they knew it had a fatal flaw, they recalled when the cost of dealing with lawsuits would exceed the cost of performing a recall. A lot of people in business think that way, and it's sad to suspect Apple is in that camp.
Still, engineering decisions are made within certain specifications and tolerances, and influenced by issues like price. So I accept that Apple cannot anticipate every audiophile application, and that there's a limit to the quality level the consumer interface can ship with. If someone wants better, they can buy a firewire or USB audio interface with higher-quality design.
The frustrating bit is that the only guideline we are given from Apple to expect on quality is "excellent", "engineered", and "pinnacle of design". Speaker manufacturers publish graphs showing the response of their system, which you can then test your unit against. Where is the noise limit specification for the headphone jack? Are we all stuck making individual appeals?
Since this problem depends on the headphones, you've got to prove that the headphones you're using are reasonable. Perhaps see if iPod headphones have the problem?
(Sadly I no longer have iPod headphones with which to test...)
Vainly crossing fingers for a fix.
At least at this point, it can pay off to speak up. My PowerBook mentioned above just had its logic board replaced in order to address a terrible whine that happened when the CPU was drawing a middle range of power. I couldn't really reproduce the horrible cases very easily until I finally found others who managed to figure out that the defect was so bad that some systems could play a nearly full volume musical scale on the analog circuitry of the power supply:

Once I could demonstrate it, they fixed it. But the problem had been there since I bought the machine, and made it nearly unusable at times.

Digital(computer) noise on headphone output jacks

Hi
I have a dv9000 which has a problem with digital(computer) noise on headphone output jacks. I hooked it up to my car
stereo axillary input jack and noticed a lot of static noise, even with laptop sound muted. Only time there is no static, or very minimal is when I put the laptop in hibernation mode. So I'm pretty sure it's a digital form of noise.
I have a HP DV5T also and it does not have this problem. So is this a common and accepted problem with all older dv9000 series laptops? Or is there a problem with my dv9000? and if so, what do you think it might be. I've looked at the dv9000 headphone output on the Oscope and I did indeed see square waveforms mixed in with other random noise.
FYI---When head phone is used, there seems to no noise or is very faint. Do headphones have inherent ability to filter out the digital form of static?
Thanks
Tom

i just bought a 4520s pro-book and i'm having the same problem but i DO hear the noise with my headphones. when i plug in my headphones i can hear every time the HD spins or a window opens or closes, and the cd drive is unbearable. this is driving me nuts because i bought this notebook for my music production so i sometimes spend hours with headphones in. i have contacted support with no success. anybody have any ideas?

Noise cancelling headphones troubles

My Sony noise cancelling headphones will randomly stop cancelling ambiant noise intermitenly by themselves. I know it's not on account of the battery because I put in a new one and it still does this. Somebody help me

Which phone and headphones do you have? which settings? etc.

When I play music on iphone5s and charging - I get feedback/buzz from noise cancelling headphones

This only happens when charging and using noise cancelling headphones (sennheiser PXC350).
I get a buzz, but if I touch the metal on top or bottom of phone the buzz goes. Electrical interference, if I turn the noise cancelling off, no buzz.
Other headphones are fine that aren't noise cancelling.
Any ideas if this is a fault with the phone?

Likely due to build up (and discharge) of static electricity (referred to as ESD). Ever scuff your feet on carpet and touch someone else? Similar concept here -- your iPad is getting charged up, probably due to movement against a nice generator like the nylon lining in your purse, and discharging through your headphones into your ears. This effect is often a bit worse in very dry climates. Perfectly harmless, but not comfortable.
To test this theory, walk around holding your iPad rather than putting it in your purse. Any better? If so, either carry your iPad or put it in something that is not going to generate static charge like the inside of your purse. Plastics and nylon are good static generators, so keep it away from those. Leather, silicone, rubber, etc. are pretty low generators, and pretty insulative to generators outside of them.

Noise reducing headphones

Any recommendations for noise reducing headphones to use on BART train? Not surprising I have noted a wide-range in prices $35 up to $200+ for Bose or Etymotics. I think I should be able to find a suitable pair for under $80, but maybe not. Any first-hand experience will be appreciated. Thanks!

If you want noise isolation then you could try investigating canal earphones. For isolation, I have found them the most effective. The only problem is discomfort from having them inserted. Some people can't handle what are basically earplugs. I wear earplugs at work so I am used to plugs.
I am using Shure E2 earphones. In store they were $99, should be cheaper online.

High Frequency Noise from Headphones Out Jack

I have isolated the following issue to audio that is monitored via the headphones output on the back of my iMac:
I've been encountering a very high-pitched (and at times a cycling through high frequencies) noise when working with headphones to monitor audio. It's not the headphones and the problem is not limited to any single application. The noise is sometimes barely audible, and it comes and goes - but repeatedly and often. Sometimes the frequency of the noise is so high that I can imagine that those with poor or compromised hearing wouldn't even notice it. But the highest frequencies are still detectable - kind of like a faint ringing in the ears or a ringing television set that has its volume turned all the way down.
I've done everything I can imagine to troubleshoot the problem including asking a Mac genius, but nobody seems to have encountered this before. The noise can be triggered off (not masked) by any other incoming audio, but eventually it reappears. I will be editing a file, the noise will appear, and I can literally silence it for the moment by pressing a volume key or playing back a portion of audio.
Anyone else experiencing this issue? Is there a fix? I do a lot of audio engineering and this problem is very distracting. I haven't purchased any outboard gear to monitor with yet, so I don't know if I will hear this noise through an external audio interface or not. Thankfully, this noise isn't being recorded to disk. It appears to be a little monster that is haunting only the playback.

OK, It is very easy to reproduce the problem, just follow this steps:
(1) Insert any headphones to iMac.
(2) Do NOT play any iTunes or any application with sound.
(3) Now, set volume with the volume control keys on your keyboard, set it to the MAX.
(4) You can keep pressing on the increase volume key and every time you hit the key you should hear a sound.
Just as when the sound stop, you will hear a high pitch. Keep repeat step 4 and wait a while, then occasionally you will hear a high pitch sound that will last to longer than 30 seconds. The high pitch will be even easier to reproduce if you alternate before decreasing volume and increase volume by 1 level, each time, wait and you will hear the high pitch too.
This high pitch sound can be heard on external speaker plug into the headphone jacks too.
BTW, I turned OFF WIFI, Bluetooth, removed all USB devices except keyboard and mouse, adjust monitor brightness, they have no effect on the high pitch, it is still there!
I am going to call the Apple Care tomorrow. Will keep you guys posted.

Noise on headphone output - 15" Ti Powerbook

Hi,
Since I've upgraded to 10.4.6 I've been getting buzzing and grumbling from my headphone output, but only when I'm running off the power adapter. The noises are influenced by window-moving and mouse clicks etc. Everything is fine when just using the powerbook's battery.
I am using cheapo cables and adapters between the laptop and my Genelec1020a's but I've not had this problem before....just wondered if anyone else has had this kind of behaviour since upgrading?
Cheers,
Bryan
Ti PB15 1GHz 1Gb Mac OS X (10.4.5)

Thanks Don,
I found an unused and still sealed gold plated stereo minijack to phono connector among the many things that I have never thrown away. My Marshall has a phono input on the aux channel. That reduced the 'noise' considerably!!! I changed the mains cable on the Marshall for a brand new one, and with a lot of wiggling in it's socket on the back of the Marshall.... Hey Presto... almost no noise at all. Very acceptable! So thank you very, very much.
Next problem-ette...
Can I import an MP3 (a paid for and downloaded musicians backing track) into Garage Band? I want to extend the song by cutting a verse and solo from the middle and adding it in to allow for a further verse and solo to lengthen the song? I have GarageBand version 3.0.5 (104.10) running on Mac OS10.5.8, but I can do stuff on more powefull macs if necessary.
Next, I want to add a har I have SM58 microphone, and a Berringer mixer, but I don't know how to connect it to the Mac, if it's possible even...
Finally, for now, can I then save and export what I've done as an MP3 and play it with iTunes again on the G3?
Sorry to be so 'demanding', but maybe you or your colleagues know some of the answers...
It's a lovely weekend ahead in Essex, so if you're in the south of England, have a warm and enjoyable weekend.

A60 excessive digital noise from headphone/ouput socket

I have a new A60 (well three or four weeks old) I work in the music industry and need to process music on the laptop. All has been fine until trying to dump to an analogue device from the audio output. The digital noise is incredibly loud! Its there all the time but just touching the mouse pad doubles the ammount of noise.
Through headphones alone its not too noticeable but through a pre-amp, well its just unuseable.
Is there anyway around this or do I need to dump the A60 and buy a ThinkPad?

I have exactly the same problem, but even with headphones it is unbearable. I can't listen to any music without having the volume turned right up. The noise is present at the same level even with the volume thumbwheel turned right down. It also varies depending on what I am doing on the laptop - its loudest when the laptop is idle. I've had the laptop nearly a year, so I think I'll just send it back before the warranty expires. Does anyone know if this is a common fault, or have I just got one that was built on a Friday afternoon ????

Processor noise through headphone jack

Do people still have the old processor hum on the headphone jack? Mine seems to be gone after an SMC reset and RAM upgrade a few months ago. Thoughts? Will it come back?
Oh, and how do I edit a posting?

Er... yes.
I got my iMac yesterday after 10 years of Windows PCs, one I.T. job too many & having a Mac mini for 10 days!
When it comes to audio I found with most PCs you'd get some noise - clicks and whirrs and whines and hisses. Even my main PC's fairly high-end Audigy 2 ZS sound card had some slight noise.
So, one thing that really impressed me with the Mac mini (apart from its size and cuteness!) was the complete absence of electrical noise or interference from the headphone socket, even with the volume on full.
However, after getting my iMac home, spending an hour in gobsmacked awe at the sheer beauty of it, then plugging in my headphones to diddle about with Garageband without annoying my green-with-envy flatmate, I was very disappointed to hear some low but noticeable electrical noise - alternating between a hiss and whine.
Usually this was only really noticeable when no sound was playing, but after 10 minutes wearing headphones for general usage it did get a bit grating. Even with the volume turned right up and down the level of the noise didn't change.
Looking at the system profiler it says that it uses an Intel High Definition Audio chip - this is probably the same one as used on (admittedly, better quality) Intel PC motherboards.
Oh.
Dear.
And there was I thinking I was spending £1,299 on something different and more special.
But have I regretted selling my main PC for £650 (it cost me £1000 to build less than a month ago! And thats without a monitor!)? Naaah... OS X over Windows any day! It's like owning an Amiga again (but thats another story!)
Anyway, what sound chip does the Mac mini and the iMac G5 have? And is anybody else noticing the electrical noise with the Intel iMac? And is there anything I can do about it without having to show my reddening face at the Apple Store again?

Noise Cancelling headphones

Does anyone know if the Sony MDR-NC8 is overall better than the NC7? I just don't know which should I get when I go to Japan this Sep. I' usually choose Sony type headphones since I always liked Sony headphones but just didn't know if the NC8 is overall better. I notice that the battery life is better on the NC8 since it's 80 hours vs 25 hours. But I just don't know if the NC8 will help to lower the jet engine sound on a plane. I can get the NC8 locally for $29 and the NC7 for $40 locally. I just assumed the newer is better since it has better technology.
Solved!
Go to Solution.

Ya I remember the bass was lacking on the NC7 but I though that they cancelled out more of the engine sound than the NC8 but I don't know. I did notice that the NC8 was more of a headphone that blocks outside sound rather than a headphone that just lowers the engine sound like around 300hz. Kinda reminds me of the Sennheiser HD280 I did try those at Best Buy at the headphone display and all they did was block every sound out there. I remember the NC6 was open type and they just took the 300hz and lowered it but when I tried the NC7 they did muffle the outside sound more and did little less lowering on the 300hz area but maybe it was just my ears thinking that. Now with the one I have which is the NC8 they seem to mostly block everything and just little bit lower the 300hz area. But the sound for the NC8 sounded way better overall then the NC7 since the NC8 had more bass or so. But I think that you need to turn up the volume more on the NC8 than the NC6 or 7 to get the same loudness as the older models. But it does say on the box for the NC8 that the noise cancelling feature works for the low frequency sounds like airplanes, trains, etc and if less effective on higher sounds like human voices. This is good since I do need to hear when people are trying to talk to me but the engine sound is what I want to lower down like the jet engine.
But I would like to know what others think and see if what I' am saying is right. If someone has heard these please reply and let me know. Thank You

Any solution to DVI noise via Headphone out?

Have posted before but I have a new i7 Macbook Pro 8GB running fine.. and I want to use the Analog/Headphone out to 2 x phono left/right into a USB Soundcard.
This is fine for recording loops from the Macbook to another editing computer, and the levels were way down at -90.0 which is almost silence.
I now have a DVI adaptor (apple) from the Macbook Pro to a DVI Dell Monitor fine, and now I have terrible buzzing, earth hum, noise!
This obviosuly ruins the recording process as I need my 2nd Monitor hooked up to the MBP. After googling this problem, it seems many many users have this same annoying problem and Apple still produce laptops with the noisy analog out?!
Is there any cure for this?
I tried to use the headphone out as Digital SPDIF out which is silent, but I can't monitor in the same way via the USB soundcard on the other machine, so that makes that tiresome and awkward. I even bit the bullet and bought a good 'ground loop isolator' to put between the Macbook output lead and the input to the soundcard lead, and that still makes no difference?
It seems to be the DVI port powering another monitor that causes this. Is there a simple solution to stop the noise?
Help!

I am not familiar with the Bumper unit, it seems very low priced, but it would be hard to believe it does not use the standard solution - a transformer, even an inexpensive one.
In the states, I have used a Radio Shack unit for this problem as an inexpensive solution which appears similar to this Maplin device:
http://www.maplin.co.uk/ground-loop-isolator-33172
The gold standard device is probably the Jensen like this:
http://www.jensen-transformers.com/ci2rr.html
but it's more like $300USD.
You may have other problems, and it would be interesting if the Apple Store can solve this for you. Otherwise, I would suggest trying the Maplin unit, and return it if it is no better than the Bumper.

Constant low rumbling noise on headphone out

There is a continual low distortion noise on my HP DM4 headphone out, which is very annoying when no sound is coming out, and still audible and disruptive when sound is playing. Is there something I can do about this, or is it a defect that I should get repaired? Thanks.

The problem seems better when I disable wifi. Just a muted thump every couple of seconds. It seems like the audio circuitry isn't properly shielded...
