Removing Effects Eliminates Stuttering .....now what? -ACID Product Family

Subject:Removing Effects Eliminates Stuttering .....now what? Posted by: fulani Date:1/20/2003 4:56:20 PM I removed all effects on the tracks and now the playback seems to be fine. (with the exception of occasional pops which are due to mysterious track splits that keep appearing. (see other thread). So what does this mean? No effects? Am I to mix without effects?!! The computer should have plenty of power to handle this I would think. P3 850/ 512RAM. windowsXP . I've done all the suggested tweaks. Could my soundcard be responsible? at present i'm using SB Live.. Also installed is an AudioMedia 3 which I use with PTLE. I tried installing the new digidesign ASIO driver to enable use of the AudioMedia card with my other music apps. But it didn't to do very well . Even worse performance. So I'm back to the SBLive card for Acid. All help is greatly appreciated.

Some plug-ins are definitely more expensive CPU-wise than others. Also some audio plug-ins will propagate "denormal" samples, very small, inaudible, samples which force the FPU to work much much slower when processing these samples downstream. Incidentally my system here is no beefier than yours so I'd like to know more about your problem project(s) to see if I can reproduce your difficulties. Thanks, --j PS. Though not ideal, you should be able to render submixes with fx and bounce them down to new tracks. Also, hitting the CPU limit shouldn't affect the rendered quality, however we may not be able to keep up in real-time...
Subject:RE: Removing Effects Eliminates Stuttering .....now what? Reply by: fulani Date:1/20/2003 6:02:07 PM thanks j. i'm using the enternal Acid effects. EQ, Reverb (rich hall, plate 1, warm ambience.... i know, i know... too many different verbs, right?), Simple Delay and a Flange/Wah on one track. is this too many? instead of rendering tracks with fx , can we set up a master fx aux bus for each effect and route the tracks to the bus, instead of having effects assigned to each track. does this make sense? would it make any difference? i'm not sure yet.

You can assign multiple effects to a bus and then assign tracks to that particular bus. Sorry I'd write more but I'm out the door. Glad to know your problems went away without effects - for me it doesn't make any difference - I still get stuttering at the end of a project - effects or not. Chris
