This view uses a split display with a spectrum T(f) on top of a profile L(t) graph.

The active panel (chart) is of blue color while the other panel is grey. Tap on a panel to activate it.

There is a header line showing the report type (Reverberation).

The function name is supplemented with the corresponding colour, microphone position and the selected frequency band.

You are now looking at the spectrum of the selected microphone position (not the average!) from the previous view.

Use the cursor keys to select a different microphone position.

Use the cursor keys or tap a frequency band to get the values for the selected band.

Tap and drag vertically on the graph to change the visible range.

Press and hold anywhere on the graph to bring up the context menu or press the large ü button

Range (Y-axis): Modifies the time [s] scale
Auto Range: Autscaling Y-Axis

The Profile chart is showing the Leq function versus time for the frequency band selected in the above spectrum graph.

Red helper lines showing the calculated decay line and its level range.

Use the cursor keys to select a different microphone position.

Tap and drag vertically on the graph to change the visible range.

Exclude this measurement position from the average calculation.

Include a previously excluded measurement into the average calculation.

Press to toggle between the different reverberation time functions (T20 – T30 – T15 – EDT/Tmax).

IMPORTANT! This is just a display feature. The calculation will always use the ‘Primary RT function’ as specified in the Reverberation Setup.

Press to toggle between single type frame and dual type frame.
