RT60 measurements

[Pierre Robidoux]

Hi,
I would like to know how to configure (if necessary) and especially how to interpret the RT60 graph and the associate data panel ISO 3382 parameters
as well as the RT60 Decay (both graphs - including the waterfall).
I whish to be able to measure RT60 for specific frequencies (250 and 2000 - required results around 1.4 s)...
Thanks.

There isn't much to configure. Choose either octave or one-third octave bands depending on whether you need one-third octave resolution. The results are generated automatically. There are 3 traces that show RT60 values, Topt, T20 and T30. They differ in the part of the impulse response used to calculate the RT60 figure, the help has details.
