CLIOwin 7 PCI User's Manual - Audiomatica

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.
