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

NEVER had this happen in Logic 8 (or any other software for that matter) on same hardware.. Not only can you not OPEN Logic 9 by clicking on a logic 9 file, SAVE in Logic 9 without it putting audio out of sync, now I discover you cannot RECORD for more than a few minutes without getting a blast of white noise. Seriously, my ears are still ringing 8 hours later from this noise. If they are still ringing Monday I am going to the hearing specialist and Apple WILL be paying the bill. I pray no serious damage has been done and that I will still be able to do mastering work. If I monitor through Logic, even at 128 the monitored audio will occasionally slip out of sync and there will be like a 2 second delay in the monitored audio, then eventually a deafening blast of white noise. To release software in this untested state is totally negligent, irresponsible and downright dangerous. Disgraceful.

After several weeks of noise-free work and foolishly lulled into believing that this problem may have mysteriously gone away, I got blasted this morning.

Booted in to my 10.6.2/9.1.1 drive. Added 17 audio files from another project. Added a couple of compressor plugs, played the song through once. All fine.

Second pass resulted in "Disk Too Slow' immediately followed by "The Blast" when I hit play again. No 3rd. party plug-ins, no freeze files, no software instruments. Started from a empty project.

Maybe 10.6.3, which supposedly has substantial core audio changes, will be a fix. My fingers are crossed.

Well, here I am just putting my hand up on this thread with the rest of you poor sods.. There I was thinking that the blast of white noise bug was limited to certain systems or caused by certain plug ins or whatnot. But I just had my first one while doing a vocal tracking session. Hooray. No ear damage though, because the minute I saw that big nasty looking block of audio at the end of a take, I knew exactly what it was (with the accompanying sense of dread), turned down my cans just to check that it really was what I thought it was.. and deleted it.

This is, indeed, not good. I don't do much heavy tracking, but I feel for you guys that do. Hope it gets addressed very soon.

If this issue is caused from a slow disk, I'd suggest you do the following;

Get a free copy of Xbench 1.3 and check your performance of your system. The things I suggest to look for is;

- disk tests, check all of your disks, especially the one your streaming your music to. Also make sure you have more than 10% of free disk space on each of these disks, especially your boot drive, as this is were the swap space is kept.

if your disk(s) become slow for any reason this might/could/maybe cause your issue. Especially any external disks; USB/Firewire drives. Remember the slowest USB device slows all the USB devices to the slowest device on the USB buss. Dont attach a drive to a slow keyboard; ie 1.0 USB, to any usb drives, especially music drives for recording music. If you must use USB drives, make sure the drive is the only device on that USB port.


- Also check your console logs for timestamps when your white blast occurs to see if the system logs any error during that time.

- Last but not least, I always have the activity monitor running checking my system cpu's and the level of them, anything over 50% for more than 5-10 secs should be looked into.


Good luck,

Magnatar

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.

• 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
