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

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.

What do you mean no plugins working? What version OS X are you using?

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
http://www.gearslutz.com/board/new-product-alert/205583-h-zed-r16-firewire-mixer -55.html

forgot to mention
i am running logic 9 on a dual core i mac with 4gig ram
using a external seagate firewire drive i believe 7500rpm
i have not got any error messages just noise

I listened to the noise mp3. That's not the blast of white noise this topic is referring to, you would know the blast because you would have to yank the headphones off or run turn the volume down... it's that loud.

Your sample sound like plain ol' digital distortion, like a preamp over-loading an A/D converter.

You say the sound is recorded on all tracks simultaneously? I suppose it could be a firewire problem. Does the ZEDr16 use drivers or is it system compliant?

pancenter-

Thanks so much for your response!!
The Zed R16 is a firewire a/d built in mixer
It does have its own driver.
It seems weird sometime a whole minuet will
go by before the next occurrence of noise.
It is not a level issue since it occurs on all tracts.
Could a firewire problem be intermittent like that?

One thing to look into is if your mixer software (if there is any) has an input level. On my firewire audio i can bring it down from zero so you and start there if no mixer software then look in the sound panel of preferences and afjust the i\o. Very important to also check if your mixer has a master gain on the input or, depending how you use it, the output and make it low as possible without effecting the mix.

It is a weird noise but i think it is due to clipping or some type of overloading. too high a signal somewhere, so try to equalize all the i\o's.

Forgot to mention, after that, if it still doesnt work out set up at 44100 Hz instead of 96 if you can. Is there a buffer size to adjust?
