3.5 TheFrequencyDetectionWindowandCPU Usage
Above the Frequency knob is the PeakProfile display, which shows the strength of
frequency content within a narrow window around the nominal detector frequency. The
width of this window in Hz is determined by the number of comb filters used in the
detector algorithm.
The CPU load of the host computer is also dependent on the number of filters used.
While newer high-performance computers can accommodate very many filters, there
might be situations where a lower CPU overhead is desirable, either for lower
performance computers or when many plug-ins need to be instantiated.
In the menu area there is the option to select one of three settings:
NarrowDetectWindow which uses fewest filters and has the lowest CPU load
NormalDetectWindow which has intermediate settings,
WideDetectWindow which has many filters and uses the highest CPU load.
Using the wide detect window setting there is approximately 5Hz either side of a 50Hz
nominal. The display will show frequency content in this window, and in AutoMode the
detector will track towards the strongest element. It is important to note that it is the
width of the window that is selectable, not the frequency resolution.
