Generic Company Place Holder DPC Latency Checker
There's a little trick that the Windows operating system uses to allow high-priority tasks such as video and audio drivers uninterrupted access to the CPU --the Delayed Procedure Call. A DPC puts off the inevitable until the system feels there's time. Unfortunately, DPCs only work to a point and can't always avoid disturbing high-bit rate audio and video recording, which requires an uninterrupted data flow. If interrupted for too long, as with a long-delayed DPC, you will hear dropouts and static. DPC Latency Checker (free) displays the amount of time these DPCs are taking so you can tune your system by disabling tasks or hardware that cause DPC spikes.
Simply keep an eye on DPC Latency Checker's graph while you disable and enable various hardware and background applications using and when the spikes disappear, you know you've found the culprit. The Wi-Fi and battery monitors on laptops are notorious for generating fat DPCs, so that might be a good place to start your hunt.
If you want to maximize your computer's performance with audio or video, DPC Latency Checker is a must-have tool. Even on a fast Intel Core i7 or Phenom system, you'll find that you can record higher bit rates and use more real time FX after you've disabled fat, DPC generating apps and hardware.
