Internal Buffer Sizes: Additionally, all three plug-ins use internal buffer sizes of 1024 for
44.1kHz and 48kHz operation and 2048 for 88.2kHz and 96kHz operation. We advise that the
buffer sizes of the sound card, and thus of the host application, are set to match these figures. If
the buffer sizes are not matched there will be an in-efficiency in the data transfer, and in some
applications this leads to uneven CPU behaviour.
DeClicker: The graphical area can be CPU-intensive if there are many detected events, for
example if the sensitivities are set very high and the thresholds are low. Additionally, the pop-up
displays can add CPU load and for that reason there is the option to turn off the pop-ups.
DeBuzzer: The peak profile window can be set to different widths. Using a wide window, which
allows for fundamental searching over a large frequency range, will mean that the CPU load will
be highest. There are the options to select either a mid-sized or narrow width window, which will
both reduce the CPU overhead.
DeNoiser: De-activating the DeHisser will reduce CPU load. De-activating the DeNoiser will
not affect CPU load significantly. There is little difference in CPU load between the Auto,
freeze, manual modes.
