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.

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 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

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.

When record audio I can`t see the graphical overview of the waveform.

When record audio I can`t see the graphical overview of the waveform.

In the Arrange Window at the bottom; click on Sample Editor:

When recording audio, the soundwaves dont show in the audio region.

I think i must of changed settings accidentally or somewhat, because prior to this, there was no problem. However, now when i record i cant see soundwaves (im not sure what they're called) in the audio region. please help, its really giving me problems cos i really wna record audio.

Try the waveform zoom slider in the lower right hand of the arrange.
If that's not it then check your recording delay in preferences>audio, supposedly if it is set too high what you describe happens.

Mouse pointer disappearing when recording audio?

I'm having trouble recording audio in presenter -- when I get started recording, after the first slide the mouse pointer seems to disappear onscreen. I can't do anything except clicking escape which brings up the save window and I can use my keyboard to navigate and click save. Then the mouse reappears.
Has this happened to anyone else? Any solutions?

Yes. This has happened to me, consistently. I am using Windows 8.1, Office 2013 (64-bit).
I have Adobe Presenter 7 and 8. I purchased 10 (as an upgrade), but it wouldn't install because the "upgrade" is ONLY available if you're upgrading from Presenter version 9 (something they don't tell you before you buy). This is a separate issue--I've asked for a refund and in the meantime, I'm using the trial version of 10.
As I record, I notice the arrow from the mouse-pointer disappears and will not re-appear. I must hit "escape" and save the work that way. I have tried re-booting, and disabling add-ins. Nothing seems to work.
I'm afraid we have another "glitch" in an Adobe Product. What else is new?

1/8 of a beat off??? when recording audio and click??? HELP

Okay so I upgraded to Logic Studio and I'm having this problem that basically has crushed my work flow... Here is the problem:
When I record new audio from my FirePod in to Logic Studio the recorded audio is approx. and 1/8 of a beat off??? It is really annoying me... Any ideas of what the problem could be? Please help if you can, thanks.
Bill K.

Thanks for the tips... but unfortunately all my settings seem to be in order??? Anything else I could try? I do record to an external 7200rpm firewire 800 drive and I have the FirePod using firewire 400... this set-up worked great with Logic 7.2???
Please help if you can

Level change when adding audio keyframes

Hi all,
I've been in Avid Land for the last few months and just came back and noticed something that was getting on my nerves when I left (I don't recall seeing this before FCP 6). When I add keyframes to my audio levels with the pen tool, I get a keyframe, but at the same time, it lowers my level as if I had added a keyframe and then dragged it down. As far as I can tell it does this every time.
Does anyone know what this is about?
Thanks,
Matt

I was having this problem, so just before I composed this reply I did some tests. It could well be 'sloppy mouse work' but I don't think so. This time the audio level went up by 1 db but before it was dropping by 1 db when adding a keyframe. During the test, no matter how accurate I was the audio level changed when adding a keyframe. The track I was working on was enlarge somewhat and the problem didn't happen on standard sized tracks. I feel that this has to be some sort of bug.
I have always found FCP a little bit on the 'accurate' side. You have to be very precise when clicking on items otherwise you will miss. Some buttons are way too small and I think Apple could improve the FCP workflow by enlarging some buttons and allowing more space around clickable items.
A good example of this is the 3 way colour corrector. The left and right buttons for blacks/mids/whites are very hard to hit and I quite often hit the maximum by mistake.
I have worked on many non-linear systems and FCP is the only one where mouse accuracy is so important.
I am, to some extent used to this now and I suppose it is a minor inconvenience in comparison to the benefits of using FCP but, in the interests of improvement and ease of use it would be good if Apple could take this onboard.
Weenie.

Quicktime Freezes When Recording Audio

Quicktime froze one time when trying to record audio, so I restarted my Mac. It still froze, so I tried repairing by using the uninstall program.
It still froze, so I uninstalled it and re-downloaded it. It's still freezing. I'm starting to think it's something in my system files but I don't really know.
The program freezes when I click the record button.
I really need help because it's the only recording program that doesn't slightly slow down my audio, so I really need it.
Any help would be appreciated.

Please, I really need help.

Logic: When recording audio, a loud electronic buzz happens

I am using Logic 9 on an iMac.
I use Logic to transfer records and create MP3s.
The record player is connected to my stereo receiver, the receiver to the input of an MAudio FW 410, the MAudio FW 410 to my external hard drive, and my hard drive to my computer (I connected the FW 410 to the hard drive because the FW410 does not have firewire 800, so I connect the FW410 to the hard drive then use the hard drive's FW 800 to connect to the computer)
This setup has always worked fine until recently.
When I transfer my records, Logic stops recording after a few minutes in, and a loud buzz is generated, and I can see the wave form of the buzz where I should be seeing the input of the audio from the record.
I then disconnected the record player to see what would happen and to eliminate the possibility that the record player was the cause of the problem. With the record player disconnected, I still got the buzz simply by arming the record button on the Logic track.
Then I tried transferring the record into GarageBand. The same buzz happened simply by arming the record button in GarageBand.
There seems to be something going on with my computer in regards to inputting sound. I'm not sure if it's a setting in Logic/GarageBand, or if there is some larger computer issues causing the buzz.
Any ideas?

How do I turn off rewire?    When I click in the box, there is no option for "off"   The only options are Playback mode, and Live mode.

Delay when recording audio compared to my midi click

Im using my Powerbook G4 1.5G and a Presonus Firebox to record audio with a midi click. I´m using the firebox mixer for monitoring and have switched off logic software monitoring. I have no latency when listening while recording, but when listening to the recorded file, it´s delayed compared to the pre-recorded click loop.
This is what I don´t understand. Why is the recorded file delayed? I have the delaycompensation off. It does not matter if I record on the internal disk or a Lacie external firewire disk.
I have a G4powermac and a motu 2408 mk3 with no problems like this what so ever.
Should i do a midi signal output correction? Is this really necessary on a setup today? Why do I not have the same problem on my G4 Powermac?
I hope somebody have an idea.

there is always some latency when the signal goes thru the computer.
you can do a test and determine how much delay you are seeing and then
go to:
audio/audio hardware & drivers/drivers
and in the recording delay box put in the amount to be compensated for.
With my setup i fugured out that I had 57 ms of delay.

Logic Pro when recording audio and midi takes, the regions sometimes become confused. The midi tracks line up with audio tracks.

When recording midi and audio tracks simutaneously the midi tracks don't always line up with the software instrument channel. They may show up on the audio track. Sometimes they appear white instead of the normal green. Any suggestions?

Hey there jlholm,
It sounds like you are seeing some unexpected behavior when you are working on your project. I would use troubleshooting steps 6-10 from the following article named:
Logic Pro X: Troubleshooting basics

Thank you for using Apple Support Communities.
All the very best,

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?

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.
BTW, Canon ZR-60 Firewire
Cheers,
Denny
