[QUOTE="Langston Holland, post: 22648, member: 171"] Re: Windoze tweeks for firewire audio recording Hi Tim: Regardless of I/O interface, successful multitrack recording with a Windows OS is dependent upon consistently available CPU time. Various drivers that keep the CPU intermittently busy, thus unable to lay down glitch-free multitrack data streams, create something called delayed procedure calls (DPC). XP tends to have several DPC issues with high track counts unless you disable certain drivers. Vista and Windows 7 addressed the DPC issue pretty well with a different audio driver system and improved hardware drivers. A very helpful gift exists to measure DPC's and find out if you need to make adjustments to the OS reliable real time performance: [url]http://www.thesycon.de/deu/latency_check.shtml[/url] Generally, with XP you'll find the need to disable the wireless Ethernet driver. If you use a Mac in Boot Camp, you'll also need to disable the KbdMgr.exe driver with the System Configuration Utility. With Vista and Windows 7 on a laptop, you'll probably only need to kill anything that throttles the CPU (like SpeedStep), hard disk, screen, etc. while plugged in (which it certainly should be during multitrack recording). It will probably help slightly to disable the wireless Ethernet driver, but in my experience it's unnecessary. With any of these OS's, if you still have high DPC latencies, you'll need to follow the instructions available on the above link and turn off one thing at a time to see where the issue(s) is.
