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

So - as someone who is just about to put a toe in the waters of Logic (and is now shrinking back ...Audition, where are you?) ... are you suggesting that Logic ONLY deals with either the AIF or the WAV and we (I) don't confuse the poor ol' b **r by having both anywhere on the system?

My ears are really too delicate to have this kind of white-noise rubbish destroying them ........

Hi,

no, if the problem was that simple, Apple would certainly have fixed it. But it seems that for some strange reason, sometimes the system makes a mistake. Mind you, I'm still not so sure if it's Logic's "fault". As said, I never had this on my Mac, and a couple of years ago I was in the studio of a PC + Cubase using friend, when the white noise blast thing happened to him...

Having been on the Cubase forums I can say that I've never seen this problem raised unless there was a hardware failure happening, specifically, a hard drive going bad or a hard drive with a lot of errors. The chances of it happening in PC land should be greater considering the thousands of hardware configurations available... so I'd say the problem lies with Logic or Core Audio. Personally... I think it's part of Logic's renown efficiency. The fact that plugins aren't active unless data is passing through them. There's a host of small problems caused by Logic's buffering.... Everything from system overloads to noise when some plugins become active, to Logic missing the first beat of a measure when starting on 1. (those are just of the top of my head)

I don't think anyone is willing to trade that efficiency for the current problem set, can't say as I blame this, using a G5 the efficiency is welcomed.

Anyway, I have no proof but always thought Logic somehow scrambles data that's held in it's buffer under high loads or slow disk access. That's why some white noise bursts don't even show up in the editor.

Just a thought or two.

pancenter-

It sounds like static from corrupted files or misread headers is a different issue than the random bursts of noise. Not that they aren't both serious problems, but probably totally unrelated to each other.

Hi,

ok, sorry, no solution, but at least something to think about: on a thread on www.gearslutz.com about this issue someone suggested that as long as this bug hasn't been solved, it's obviously very wise to put all digital volume controls (the main volume slider in Logic, main volume controls of your audio hardware) as high as possible, so that the levels of the analog stuff that comes after that (like main volume of the monitors) can be as low as possible. As long as you don't overdrive them, it holds noise levels down, and IF the noise burst appears, it will probably be less loud because the you've actually given the monitors less headroom.
I know, it shouldn't be necessary...

If by "main volume" you're talking about Logic's master volume, then no, it's not a good idea at all. Doing so will drive up the level of all Logic outputs. And whereas channel strips can be driven into the red without distortion, outputs cannot.

So.. Has this not been resolved? Im also experiencing all the problems above. As already said previously.. If I even have only a blank midi track in my arrange, the horrific noise occurs between between bar 6 and 8, then disappears. Im a professional producer and to be frank, could not put up with this and have already 'flow the nest' so to speak and have had to invest in ableton Live 8. From being a logic user for over 9 years I did not want to do this. Sod the **** iphones and all the ipad's for a minute.. look after us all like Emagic used to.

Also, I own a pair of £2000+ monitors that I hope haven't been fried / damaged by the noise outburst's and that I haven't suffered any hearing damage (yet to be tested).... I would personally like to know what my rights are against apple.

JohnF,

Are you able to reproduce this problem consistently in a blank song between bars 6 and 8?

Hey iSwartz,

Reinstalled my whole computer and at the moment the noise isn't there.. I did this a while ago and it disappeared only to return. If it returns, I will get back on the board and hopefully get a recording of it, yet as said.. I've 'flow the nest' and am really digging Ableton (it seems to have memory issues but at least I don't live in fear of the horrible noise thing).. I do hope apple sort all this mess out as I want to work in Ableton and then mix in logic now.

Regards,
Jon

Hi,

is anybody who is still suffering the "blast of white noise" already using Logic 9.1.1, not a older version?

I haven't experienced this problem with 9.1.1 so far...

If you think Ableton can't do this too, think again. On a Dell (and also on a Mac).

The grass is always greener.

21st, from the research myself and others have done on the 'net the problem is not specific to Logic, or specifically version 8 or 9. The link in 45RPM's post is also indicative of this. The blast has been reported on PT rigs as well.

I wouldn't know if it occurs with remotely the same frequency on PC-based DAWs or not because, well, what's a PC? (LOL) but considering Apple has contacted some people to get info on the problem it might be safe to say that it's specific to Macs. Or it might not. Regardless, the problem does occur in conjunction with their hardware while using their software so as far as I'm concerned -- as are the bent cilia in my cochlea from my encounter with this -- the ball is in their court to figure it out.

yes, I know that, but I was told that Logic 9.1.1 includes some kind of protection against situations that provoke this "blast".

Curious to know -- where did you got this information from?

And if you look back through this thread just one page you'll see a report of this with 9.1.1. Go back two pages and you'll see two additional reports on 9.1.1

Yes.

For me, I've only had the B.O.W.N since 9.0, all versions, including 9.1.1. 10.5 or 10.6 hasn't made a difference (I thought it was just LP9+10.6 once, but I was wrong). Never with LP8.

I've spent many, many hours trying different combinations of OS and Logic versions, even changing interfaces connected from firewire and PCI . Because it can strike at any time, I can't find any repeatable combination which will induce the noise. It's also infrequent; I could run for weeks with no problem, then get hit twice in the same day.

I don't use Logic for recording at the moment when musicians are around, and so far haven't had the issue. Not that this means much; maybe I could have used Logic without a problem, but I'm choosing not to risk it until a solution is found.

Although it seems that loud noises have occurred on other platforms, the incidents seem rather rare by comparison, and I don't think it's because PT or Live users are shy in reporting problems.
