LatencyMon is a free latency checker software for Windows. It checks the system latency to determine whether your PC can handle the real-time audio streaming or not. To check system latency, it first monitors the system in real time and tracks parameters like current and highest interrupt to process latency, highest reported ISR & DPC routine execution times, etc. All of the monitored parameters and their real-time values can be viewed on the interface. Plus, it also displays an evaluated result on the interface that tells about the system capability to handle real-time audio streaming.
In this software, you can stop or restart test again by pressing start or stop monitoring buttons at any time. Plus, to view the complete result with detailed system information, use its stats tab. Besides this, three more tabs named processes (it shows detailed information of all running process), drivers (it shows detailed information of all installed drivers), and CPU’s (it shows ISR and DPC count and execution time of each core) are also available. In general, it is an easy to use latency checker that provides a lot more detailed result than other similar software.
