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

FWIW...

I've never had this problem recording in Logic. Never. Regardless of version (L7, L8, L9) or interface (built-in audio, MOTU 2408/PCIe-424, or RME FF800).

So is it a Logic problem? A CoreAudio problem? A FW-specific problem? Hard to >say.

I've only had it one time and thought it was Logic/OSX related, it seemed OSX was busy doing something else and Logic started to behave in a manner that precludes the "Audio/MIDI sync error" notification. It was also one of the few times I was using a Firewire interface, normally I use the old RME PCI card which has been solid for years. Hmmmm... could definitely be Firewire related since that's what most everyone is using now.

pancenter-

BTW, and FWIW, this used to happen with Logic 4 and Logic 7 once in a while (my audio interface being exclusively the PCI card-based MOTU system). The problem was _very specifically limited_ to the recording of WAV files. Now even though that's a bit of ancient history, sometimes behaviors of older systems make their way into newer ones. So...

Could it have something to do with WAV files?

I think that's probably a separate issue, Logic would either write or read the WAV file incorrectly and scramble the file header (big endian/little endian) byte order. This still happens when Logic imports an OMF with 24-bit WAV files, it tries to read them as AIF and ""blast"".

I don't know if this is the same problem but I installed a Digidesign Mbox today and when I had hooked it up and clicked 'apply changes' in core audio prefs, I got a loud blast of white noise.
It was gone on reboot.

I'm absolutely not shure if it has something to do with this problem, so if I'm completely wrong, please disregard.
I had problems with random 'white noise attacks' a while back (Logic 8) with a Tascam FW-1884. It happened in the middle of playback or recording, for a couple of seconds, and then it went back to normal.
What solved the problem for me was a separate Firewire Card which I installed in my MacPro (I think it's a Lacie FW400-Card with Texas Chipsets). After this, it never happened again in Logic 8 and so far in 9.0.2. I always found that strange, because I had absolutely NOTHING ELSE connected to any of the Firewire-Ports of the MacPro. And I didn't change anything else (drivers...).
It just crossed my mind, because a lot of people with the problem use Firewire-Interfaces. Has anyone had this problem working with only the internal In- and Outputs of the Mac?
But as I said before, it could be a specific Tascam-problem or a problem with my specific setup as well and it has maybe absolutely nothing to do with the described problem.

same problem here had a few singers scared ******** in the recording boot. never happened in logic 8, only in 9, and only when recording. Usually happens after we recorderd for about 10 to 15 minutes. Always happens once during a session and doesnt come back after that. Its very very anoying especially for people who take good care of their ears.

This has happened to me a few times recently too. Once or twice with cans too.....NOT much fun.

It's always accompanied by a message saying "disk too slow" and a disconcerted vocalist. Recently I've been getting a lot of "disk too slow" messages when I'm not recording too BTW - something that only recently started popping up.

I'm recording onto my internal hard drive (with plenty of free space), everything is up to date, except logic (I'm not on 9.0.2 yet)

The "blast of white noise" issue is one of the reasons I haven't upgraded to Logic 9 yet. I have never experienced this issue in Logic 8. UNTIL this weekend! I had a session and was recording an acoustic guitar and a vocalist simultaneously and wammo a big burst of white noise! It scared everyone! Didn't happen again the rest of the session and the first time this has ever happened. Weird!

I am on Logic 8.0.2 OS 10.4.11...

I'm not sure if this is any help but I had the "blast" problem when I used a USB interface (Line 6), since switching to a firewire interface (Presonus) has fixed the issue for me.

That's not the issue causing this. This problem has also been reported by users of Firewire Interfaces, and (like me) users of PCI card interfaces.

Best I can tell, it's across the board, and what type of audio interface is being used is of no relevance.

This is happening on my new G5. My ears are still ringing too and I'm sure that it has caused some permanent hearing loss, really a horrible thing.

I have a Quad-Core G5 with an Apogee Ensemble connected via Firewire. I have Logic 9 on the mac, but this happens to me even if logic is not running. I can just be checking email and get blasted. It happens a couple of times a day.

It ***** because I just paid a mint to get an Intel mac to run my sound apps with Logic 9 and now I'm afraid to even turn on the speakers for fear that I will never hear again.

I wish I was still running protools on my pre-intel G4 POS.

I'm not convinced this is just Logic. I found this thread from Googling for OSX White Noise. I'm not using Logic but I'm still getting the white noise blasts. I'm using a USB soundcard that appears to periodically crash resulting in a blast of noise. Sometimes it's related to MIDI input, so maybe the USB connections cannot handle the amount of data being send through to the Mac?

This is my 3rd "me too" for the week. I recorded (with major trepidation) over the weekend, and experienced this. I avoided hearing loss because Logic gave the "disk too slow" error, and remembering this thread, I quickly pulled the cans off my head.

I didn't hear the blast, but you could see the white noise @ the end of the audio file. I rebooted, and continued recording (at volumes as low as I could and still hear) without incident. I'm thankful for the error as a warning.

This s**t has me freaked out, and afraid to record. I don't know if it's the software or the OS (and don't care), it's unacceptable.

hmm,


So far I've been spared this (serious knock on wood) - it does seem difficult to pin down judging by people's varied specs. One thought - since this seems to be preceded by a disk-too-slow-error, it may have something to do with the formatting of the disks - journaling on/off, partitions etc.

Maybe, since everything else has come up short, everyone who is having these problems should compare notes on how their system (and maybe session) drives are formatted. Mine are MacOS Extended (Journaled) with just one partition on the sessions drive, the system runs off one of two partitions.

I'm having a problem of similar nature. I'm using Logic 8, and I'll be recording with a Profire 2626, and while it hasn't happened mid-tracking yet, it will happen during playback. The waveform will appear perfectly normal but as soon as it starts playing the newly recorded track, I get a blast of this same noise. If I reboot Logic, I get the "Invalid Header Data" message asking if I want to repair it. After that everything is fine (until it happens again on another new track).

Again, the waveform shows no signs of anything other the audio that was recorded, but that is definitely NOT what I hear. I'm going to start laying down drums for my bands demo, and I'm suddenly really nervous that I'm going to run into this problem right in the middle of recording a take and fry everyone's ear drums.

Has apple even commented on this issue? Because if not, that seems kind of ridiculous to me. As with every one of the frustrated users here, any feedback is appreciated. Thanks all.

I think you'll find M-Audio us the culprit, I got rid of mine for the same reason, and never heard it again.

ps If the OP has any luck with suing Apple for his hearing loss, tell them to expect a class action suit for my limp remixes, I just can't get them fat enough, LOL

I posted this elsewhere but got no response and thought it was appropriate to post here. I don't know if it's the same problem because this was during an offline bounce, but essentially the outcome is the same: LOUD burst of digital noise. I have a screenshot to prove it where you can see the waveform (I no longer have the audio file)...

I've had other strange things happen on offline bounces with 9 which I've never seen before (or imagined possible) - like the whole bounce just dropping to silence half way through.

Fantastic! I might forward this to the Logic Feedback people. Might serve as crucial evidence!

Its not an M-Audio Interface problem. Its been reported by users of varying audio interfaces.

My audio drive is formatted Mac OS Extended non-journaled, which is the recommended formatting for your audio drive. But this has always been the case in all my audio drives over the years. That aspect has never changed (since OSX that is). Other users experiencing this... what are your formatting specs?

But Logic 8 was the first version of Logic to have this happen, as far as I can recall. Its the first version that I experienced it, and having been a Logic user since version 4, and a moderator on another Logic forum, it wasn't until Logic 8 that I even started reading about it.

But it seems even more prevalent in Logic 9, that's for sure.
