Use this option to determine whether room parameters are calculated (and optionally plotted) in
whole or 1/3-octave frequency bands.
The IR or squared IR in the analysis tab may be viewed after being filtered into whole or 1/3-
octave frequency bands. Tap this item to select from a list of frequency bands which version of
the IR data should be plotted in the display.
Tap this item to select which acoustical parameter should be displayed for the current room
Early Time Cutoff (te)
Use the text box to enter a
value for te, in milliseconds. As an example, if you would like to calculate C30, select Cte as
the current parameter and enter 0.03 in this text box (you can also type in 30m, which will be
interpreted as 30 milliseconds).
The Room Analyzer can normalize the IR data so that it's peak value is 1. This can make it
easier to see the amount of decay in the squared IR plot. This option is on by default.
Use the Autoscale switch to enable or disable autoscaling of the analysis display. Autoscale can
optionally be toggled with a double-tap within the vertical axis label region of the plot.
Plot Regression Line
As per ISO 3382, the Room Analyzer performs linear regression analysis on the decay curve to
estimate reverberation times. Enabling this option will cause the resulting linear regression
line to be plotted along with the decay curve in the Squared IR plot.
The cursor may be configured to automatically move to the frequency of the peak value
within the current data being plotted. The switch turns the peak track function on or off. (Peak
track can also be toggled with a triple tap inside the data plot.)
Use this switch to select whether or not a horizontal bar will be added to the cursor line,
corresponding to the value of the data at the cursor's present location.
Horiz. Bar on Decay Curve
Since both the squared IR and the decay curve are displayed simultaneously, this switch can be
used to determine whether the horizontal cursor bar, if enabled, will correspond to the decay
curve value or the square IR value at the cursor's present location.
Set Decay Curve Limits
Dual cursors are available within the squared IR plot. When this option is enabled, the
Schroeder decay curve integration will only take place between the two cursors. The decay curve
and corresponding parameter values will be updated dynamically as either of the cursors is
moved. This does not affect the Room Analyzer's automatic calculation of T=0 (the onset of the
direct sound) which is used in the calculation of Clarity and Definition.
