My ears are ringing from blast of white noise from Logic 9

Could everybody with this problem please see if "internal", "Line in ", "Digital In" or "Internal Microphone" is selected in System Preferences> Sound > Input?

Maybe it has something to do with selecting multiple input sources.

Mine has SaffireLE selected for everything. I dont use logic but get it through other audio programs that use instruments. Never get it from simple playback of audio cd's, youtube etc.

Disabled airport (deleted afaik, doesnt show up in running services), moved to front firewire port. From some suggestion i read here but have not tested it out yet.

Also, i have journaling enabled for 'Macintosh HD' drive which is main drive but disabled on other drives. Software i use is installed on the HD drive and does not use other drives. I am at a loss if these little changes dont work.

Well, like everyone else mentioned this is no little glitch. I use this system professionally in a live situation.

1. Should i disable journaling on the HD drive?

2. Should i get another Firewire card that will not have this problem? are there any?

3. Should i revert to original install disks, prior to snow leopard?

Oh my Lord I'm really getting these stabs of noise this morning!!!

Tracking some guitar... seems to be glitching a bit during recording, then suddenly: Kkkrrrrggggghhhhhh!!!!!!

Several times now... Really loud and really unpleasant. I think it's the first time I've had it on my G5.

Going back in now after a restart - fingers crossed.

Do I get points for spelling it correctly?

Hi,
I reported the problem to the Apple support for some month ago.
On feb 9th I got this email back:

"Thank you for your recent submission to the Customer Feedback page for Logic Pro. Information that we obtain from you and your peers is highly valued as it helps us to constantly improve our applications.

We're sorry to hear that you're experiencing what sounds like a pretty serious issue. Our team has been trying to isolate the problem you describe but have been unable to duplicate the behavior so far. Recreating the behavior is often the hardest step toward solving a problem. Would you be willing to answering a fairly extensive set of questions to help us isolate this issue?

many thanks,

The Logic Quality Assurance Team"

Of course I answered that I'm willing to answering every question.
Didn't got the questions yet, but I have hope that they are solving the problem soon.

I've experienced this white noise problem only once in the year I've had my Mac & Logic 8 and it left me with ringing ears Very very, dangerous to hearing and I hope Apple are taking the problem VERY seriously indeed.

This problem is so very serious. My head is ringing as I type this as it just happened to me. It has happened on Logic 9, 9.01, 9.02 and now on 9.1 😟. I don't think it's safe to mix or work on Logic with headphones anymore. I just can't risk losing my hearing over this.

This is definitely not acceptable. I sure hope they pin this down. I might look to go to Cubase or Samplitude on PC. This is like the 10th time it's done it to me and it scares the bejesus out of me.

Sad times for Logic. Such a great package but this one is an absolute show stopper. Not an inconvenience, a complete show stopper.

Rumour has it that this may be a core audio issue that will be addressed in the 10.6.3 update which is so to be available. I hope it is I've had this problem several times all in different circumstances so it is hard to pin down

Hmm hopefully they will do something about it in 10.5.8 as well. I suppose if I absolutely had to I could go to 10.6 but I would have to spend 500 dollars to upgrade my RME Cardbus to Expresscard interface. It would just be cheaper to move over to Samplitude or Cubase and at least with Cubase, I would get dual platform support. Also, if it is a "Core Audio" issue, wouldn't that mean ALL DAW's on OS X would do this?

Getting over learning curves of new DAWs ***** but so does losing your hearing. It wouldn't be so bad if I didn't have to wear headphones for 8 hours a day (because of all the other people who work around me we all have to wear headphones). Plus the room is not ideal at all for mixing. With headphones though, obviously the room is taken out of the equation until I can get back to my studio and check the mix on my monitors.

For me, every single time this has happened it was the exact same situation. Loaded up Logic 9, opened a previous project (which was no audio, all midi samples from Vienna Symphonic Library) using VSL's VI plug-in on each channel. It was ALWAYS the INSTANT I hit play. BOOOM! Yesterday when it happened to me, my mind even told me OH CRAP you hit play to soon! And yup. BOOM!

So it had something to do with me being to hasty and hitting play before it could actually completely finish loading samples, and external samples drives waking up and spin up for streaming. I have never ever had it happen "while playing back" such as in the middle of the song or end etc. It is always right at the initial start out. I have since found myself covering my ears before I hit play. Then once it plays a few seconds of song, I can then put on my headphones and play it. So it does sound like some type of malfunction in Logic's understanding of how to handle when a disk isn't or hasn't been keeping up. I could be wrong, but that's been my experiences so far.

I will say though that Apple seems to be at least trying harder then ever. They are releasing updates constantly and giving us more and more each time for an incredible price. Which gives me some faith they will solve this. Even so, maybe it's not a bad idea to have 2 DAW's anyway as a back up plan for times like this.

Are you sure it isnt a plug in issue? I updated a plugin (the only plug in i use) and it has doesnt happen anymore. The last time was a few weeks ago, so for my system it is fixed. Also, i am using Soundtrack Pro but i doubt that makes a difference. The last time was a few weeks ago.

Okay party peoples. It's not a Logic issue, therefore not exclusively a plug-in issue.

The "blast" happens with Final Cut Pro, (trust me, I know) so draw your own conclusions.

Methinks core-audio. Most likely culprit.

When it was happening to me the waveform someone uploaded looked just like it. Load blast and steady, had to close the program.

I updated the plug in and it stopped happening instantly. I know because it would happen after an hour or two.

Since then i upgraded final cut studio 2 to 3. Your audio plugins load into final cut pro too. Remove all the external audio plugins from final cut pro, i dont use them in it anyway.

My soundcard is also firewire. I am using snow leaopard 10.6.2. Worth a shot because it was an easy fix and it is working great.

I dont use Logic9 but i do use Soundtrack Pro which also had the problem for me.

This happens with NO plugins loaded whatsoever. Firewire/usb/internal soundcards make no difference either. Thr third party plugin excuse is typical but doesn't apply here. I do believe this is a core audio issue which has been reported to Apple well over 2 years ago. As the apps become more demanding, the problem becomes more "visible", that's all. Hopefully the devs are finally taking notice.

Yeah, it does not seam to have anything to do with plug-ins. It's happened to me with no plugs working. I have also received the email from apple and I have supplied them with information they asked for. Hopefully, they will be able to find a fix for this problem.

I guess that just happened with me for the first time - and last, I hope. 2 vocal tracks and 1 drum loop playing, no instrument track or 3rd party plugins in the project at all (not even the native ones, probably just a Channel EQ on the master track). Playing - stops (like before there's a "system overload" message) - NOISE.

Hi
I just bought a ZED r16 firwire mixing board and have been blaming
the ZED for strange noise that occurs during recording simultaneously on all channels being
recorded randomly? I usually don't monitor the recording as it is being made
but the noise has been present in almost all of my recordings during playback
the actual noise is in the recording since it can be played back over and over.
I posted a little mp3 of the noise on gearslutz i am user echo44 here is a link
to my post with an mp3 attachment do you guys think this is the white noise problem or a problem with the ZED mixer? It is post #1639 at the bottom of the page
