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

My own white noise issue was solved when I turned the volume control on my external speakers down slightly. I can crank the Apple menu control to the hilt and never have a problem now. It worked for me and I don't have the issue at all without the external speakers plugged in.

This is not a Logic problem, but as others have suggested it must be core audio. I've gotten it several times while using fcp7. Mostly out of the line out or headphones out. I've never heard it when monitoring via blackmagic multibridge, but that may be coincidence since I rarely monitor audio that way.

Come on Apple!!! How can this not be fixed yet??? A bug that is physically harming your customer's eardrums should be a priority!

FCP7 may well use some of Logic's audio technolgy. The reason I say that is this problem has been around for a long time, and over several different OS releases, traces of it go as far back as Logic 4.x.

It's more prevelent now, possibly because of the added weight of recent OSX releases... there's a lot going on all the time, the OS is consistently touching the system drive, Leopard in it's most recent incarnations seldom sits still.

Just figured Id through my 2 cents in. While transferring tracks from the Roland 1680 I got my first blast. A dark blue block on the track for about a second. It was at that second updater kick in. Just a thought.

Yep, that's what I was speaking of in my previous post... there's no way OSX should be doing much of anything with Logic open and recording. I would put update into manual mode.

Thanks Pancenter,
I put update into manual mode. I was working at low volume with the monitors. And it was loud. Now I'm scared. I often record 8 tracks of drums with the click track cranked in the headphones. This ain't good.

Have you experienced blasts of white noise while using Logic to record or play back audio?
• No

Under what conditions has the noise occured?
• N/A

After recording audio, has the waveform overview ever looked normal but playback resulted in white noise?
• N/A

After recording audio, has the waveform overview ever appeared like a thick solid white bar that filled the entire waveform display (peak-to-peak waveform level)?
• No

<Edited by Host>

Why does the 'host' keep deleting/editing my post rather than replying to it with answers? Is this problem fixed and I don't know about it? Very poor customer service. I expect this post to disappear too; unanswered. 😟

Well, that would make you extremely ignorant. For instance, the data that was compiled would be inaccurate if users who weren't experiencing the problem weren't a part of that. Secondly, just because I havn't experienced the problem doesn't mean I might not be prone to it. It's not an 'elite' club. I have every right to post my concern.

I'm also well aware that this is for users of apple products. I was merely illustrating that moderators have the time to delete/edit posts and nothing more. I wasn't initially looking for moderator input. There are plenty of unedited posts in this thread that aren't constructive in their criticisms.

Just because this thread is still alive does not indicate to me that it's being taken seriously by Apple. The fact this thread has been alive since September but nothing official regarding this has been circulated would suggest quite the opposite to me.

My first post was deleted. I signed up to post in this particular thread just because i was so alarmed about it. I too often record drums with everything cranked up in my cans and it's quite a scary thought really.

I was just indicating in that post that there are no connections between users experiencing this white noise: Different applications (some DAW, some not), some using internal audio, some FW, some USB, some with plugins, some without, different OSX, different software versions..

Hi Guys,

Any solution for that issue? I have the same problem and I unable to fix it. I checked out all the internet discussion forums, restore the system, optimize it, tried to record to the internal HD, external one, I tried all different kinds of properties in Logic 9, basically everything was possible... I have this terrible noise when I recording microphone at 3:38 (sec). Previously it said at 3:38 "Disk is too slow (record)", but I only recorded a single microphone in a new Logic document. Its basically killing me, I cannot do anything. I am researching and reading for 3 days now, trying every advice, nothing helped.... Please let me know, if you know something smart. I have an Edirol FA-101 audio interface with buit in driver in Snow Leopard.

Pete,

Did you check the system for errors by opening the console application in the application/utilities directory ?

I helped a friend recently who was complaining of click/distortion sounds coming from his Mac Pro Garageband and Presonus DAW setup, as well as long sync up times to the Presonus device.

His Presonus device was flashing red, blue, the red, then blue, repeat, repeat, repeat...... usually mine takes one red blue flash after the initial hw check the presonus does before trying to sync to external FW devices.

While playing back all tracks with a live lead track, I opened the console and it was and had been spitting out '1394' errors every couple secs. I unplugged the Firewire cable on the presonus side and watched console output, the 1394 errors went away. We checked all other firewire ports and cables, but the source of the noise was coming from the presonus device having a fw sync issues.

Checked the presonus sites for current downloads. There is one for the device, but the read me documents did not state this was a fix for fw errors.

So in closing, the point here is the slow disk report could be;

- your edirol FA-101, check the console output. Try what we did by unplugging your edirol and watch for errors, or try to record from the computers mic input if possible.

- make sure you have more than 10% disk space left on boot up drive, as well as any other drive attached for not enough free disk space. This can definitely cause the 'too slow disk' error.

- run xbench a free download to check your system perf and disk thru-put and compare with similar macs, observe disk speeds, ram performance, and lastly CPU speed. Again compare against xbench.

- the last is check what your system really is doing, use the activity monitor and observe the cpu meter/s. Right after a reboot without Logic running, the cpu should be less than 10-15% if not less. If its larger your system could be busy like I've seen personally, an old print job trying to print to a printer we no longer have....

PS: not having white blast issue and use Logic 9.1.1 with 10.6X on a Intel Mac Pro Logic @ 2-3 hrs week. Hope I don't jinx myself now .....

Good Luck

I had the same white noise in Logic 8, sometimes spurts, sometimes like a scratchy record. Using a Mac Pro, Tiger 10.4.11, with logic Studio, I made sure I had the latest firmware for my audio interface and I unplugged everything from the back of my display monitor and any fire wire from my computer I wasn't using while recording..... and it all went away, no more white noise.

Good point, this can make a huge difference on USB and Firewire bus performance. Pay close attention to;

"What 'else' is daisy chained from that same usb or firewire port that your DAW and/or Drive is plugged into"

Heres a USB DAW example

Try to keep slow devices on one port; ie older printers, keyboards, game controller, etc... and put your fast devices on the another port; ie DAW, Disk drives, SLR camera's, and such.

Now firewire is similar, 800 vs 400, keep em separated.

Although I do the same as CLB64 states, unplug unused devices from your system. I Also prefer Firewire over USB for DAW.

Try to be Creative....

Just Happened to me....

My ears are killing me AND my tweeters blew up.....
This is dangerous.

Blast of White Noiz.
I was NOT recording audio. I was in the piano roll editor and playing back

I am running VE Pro
OS 10.6.3
Logic 9.1 (32 bit mode)
