10.5 OTHER TIME DOMAIN INFORMATION
Besides the impulse response we already dealt with, CLIO gives three more time
related post processing, which are ETC, Step Response and Schroeder Plots. The
last is room acoustic oriented and we will handle it later with a T60 calculation
example. ETC and Step Response are shown here, Fig.10.28 and 10.29; they are
relative to the system of Fig.10.15.
Figure 10.28
Interpretation of ETC, besides the most obvious things which are labeled inside the
figure, requires some theoretic digressions beyond the scope of this user manual as
the topic is still debated.
Figure 10.29
Step response is very useful to identify differences in arrival time between drivers
as well as their polarity.
