Hang on silences!
#977415 - 22/03/12 09:03 AM

Hello every body.

I'm using Ableton Suite 8 on my hp probook 4530s, corei5 sandy bridge,4gigs of ram and win7 sp1.
Ableton runs really good but my cpu meter rises up to 500~800% at clip ends, reverb tails, sudden silences, soloing a track and so on. It's really strange to me that the system can handle lots of tracks and plugins as well but it dies when the load is off.

Can you justify this?
Any solutions?

Thanks.

I don't know whether this applies to you but I had similar problems in Cubase a while back when using some of the Antress Modern plug-ins. I felt as though the less signal they had to work with the more they struggled & CPU usage rocketed even after I'd stopped playback. I had limited success with gating the signals when soloed but eventually admitted defeat. Funny cos I could use multiple instances of iZotope Ozone & Nebula (notorious CPU hogs) without a glitch.

Sounds a bit like the de-normalising bug that was a problem a few years ago.

has a few links to articles about it. I think there may also be some threads about it in the forum - hopfully Martin might know how to find them.

Actually I discussed this problem way back in my October 2002 PC Notes column:

www.soundonsound.com/sos/oct02/articles/pcnotes1002.asp

If you want to test out elderly plug-ins for this problem there are several plug-ins that can add a tiny (inaudible) amount of background noise ahead of an offending plug-in design to make sure the denormal problem never arises.

A good example that’s still available is TObybear’s P-Bugger, downloadable in his donationware UtilBag collection here:

Problem solved

That very useful article linked above helped me and let me tell you that Lexicon Native plugins were the cause.

Thank you.
