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

http://www.logicprohelp.com/viewtopic.php?t=49993

Above is a link to a thread on this topic that started recently on LPH. I've linked that thread this thread.

I think the only way to find out if there's a common denominator here is for someone to compile the data on everyone's system. My suggestion would be for everyone -- whether you've experienced this problem or not -- to post back here with the following information +in exactly the following format+ (so that it's easy for someone to read and compile the data from it). Here's my suggested questions and format. Feel free to chime in if you think there should be additional questions.

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

*Under what conditions has the noise occured?*
a) recording only
b) playback only
c) both

*After recording audio, has the waveform overview ever looked normal but playback resulted in white noise?*
• Yes or No

*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)?*
• Yes or No

Computer -- +complete specs+ of your Mac, including:
• type (Mac Pro, G5 PPC, etc.)
• # of processors and speed
• amount of RAM

OS
• version #

Logic
• Version # on which you experience this problem
(and don't just say "Logic Pro". Indicate the exact rev, i.e., "8.0.2" or "9.0.0")

Frequency
• how many times have you experienced this problem? (answering "never" is OK too)

*Audio Interface*
• Make/model
• connection type (PCI-card, FW, etc.)
• Indicate "built-in audio" if you don't have a separate interface

*Hard Drives* -- list each audio drive which you've used in the course of production and from which audio recording or playback has resulted in a white noise blast. +Leave this part blank if you don't experience the white noise problem.+
• Make/model, capacity
• Type: internal or external
• Interface (FW400, FW800, eSATA, SATA, etc.)
• Is this your system drive? Yes/No
• Journaling: On/Off
• if using a FW or eSATA drive, is the drive daisy-chained to any other devices? If so, describe the chain...

*Add'l Info and Observations*
(be brief!)

Only ever experienced random pops and clicks in 8.0.2 never 'white noise.' For me, this seems related to a core audio glitch with 9.0.2

Thanks for your efforts, iS 😎

tried both journaling on and off, no luck. tried both saving to the system disk and to the second hd i normally use, no luck.

Add'l Info and Observations

Seems to happen only when recording long sessions, after about 20 to 30min into the recording session. System doesnt crash, just a big boost of whitenoise which is visible in the waveform.

I had my first encounter with that white noise blast two days ago after two months of working on Logic 9. Couldn't reroduce it afterwards but it sure was loud and bad being in the middle of a big Mix with the speakers cranked fully up.

Sampleconstruct, it would be great if you could post back with your answers to the questionnaire I posted above.

Thanks for putting this together iS. It gives one a clearer idea of what Apple "Support" would theoretically look like, if it existed....

Add'l Info and Observations

In addition to the above however, I have had an incredibly nasty burst of white noise (very similar to the video posted by a user on the LPH thread) when using the TC electronic M30 reverb that was recently given away for free. I am not the only one to report this happening in Logic with various systems, so it may be worth reading this thread for a few more clues. Perhaps I should have answered yes to the above first question, but having never experienced it before and being able to reproduce it with the M30 plugin I think it would have been irrelevant.

This has happened less frequently on Logic 8 and has gotten much worse on 9. This has also been reported to Apple on numerous occasions. Not a day goes by by without this happening at least once. Seeing it in the waveform at least allows me to prevent playback from damage.

Have you experienced blasts of white noise while using Logic to record or play back audio?
-both

-I have seen both the abnormal waveform (big block of black), as well as a normal looking waveform, that plays back white noise.

I too, experienced this periodically in Logic 8, but for me, it was only on playback. Logic 9 has added blasting the white noise while in record as well as playback.
