evaluation it should therefore have been stopped before it is processed. The time
the system evaluates the signal is usually defined as Meter On time. This is
automatically set by CLIO around the value of 6 ms, as long as the Frequency
involved is high enough to allow this. Fig.11.6 is a plot of the Meter On Time Vs
Frequency CLIO uses.

Users should use this graphic to determine the lowest Frequency that has been
measured in anechoic state. Using a fixed predefined Microphone and Loudspeaker
location makes all these parameters easier to define in routine measurement
processes. But for new situations it’s very advisable to run an MLS and have a look
at the impulse response obtained. Fig.11.7 shows the labels of the corresponding
data to be input as gating parameters.
