Idle Interval: As the Sound Processing Live procedure handles input sound files from multiple channels, and in order to maximize the speed of the frequency analysis, this module might be less responsive to user input. The idle time between processing gives the module some extra time to respond to your input. Increase it value if you want to improve responsiveness. If you set and idle time of 100ms, SA will wait 100s after finishing the processing of any one sound. The faster your PC, the less idle time needed.

Slow Down Execution: Depending on your system, demands imposed by the Sound Processing Live module might interfere with the Recorder module. In particular, the playbacks regimen might crush if the processor is 100% busy with analysis for too long. To overcome this problem, you should slow down the execution of the live analysis. This is done by halting execution for very short durations during the spectral analysis. You want to decrease processor load to about 60-70%. To do so, start the Windows Task Manager (control-alt-del) and click performance.

Then Start the Live analysis while the SA Recorder is running, and watch the CPU usage during the analysis (as sonograms appear on the screen). Then increase the 'Slow-down execution' value until you see that the peak CPU usage is down to 80% or less.
