The Energy Decay Curve can be configured to show a band-filtered version in addition to the default full-range display.
By default, the Energy Decay Curve shows the unfiltered energy decay of the impulse response. However, you can choose to view a band-filtered version of the Energy Decay Curve over any of the standard octave or third-octave bands.
This PopUp control is only visible when either the Octave Band or Third Octave Band options are selected above. Once the band decomposition is selected, you can choose one of the standard bands from a list of those appropriate for the measurement record's sample rate.
