⑩ Realtime Settings (these controls may be adjusted only in Realtime Mode, “Stitch Depth” is set here and
persists in recorded sessions) (
⑪ Image Settings (These controls effect the color gradient information shown in the Acoustic Image) (
⑫ Blue Position Line (This line demarcates the time focus of the session in the video window and the
spectrogram; moving this line will alter the Time axis of the spectrogram)
⑬ Timeline Ruler (This area indicates the length of a recorded session as a timespan. The Blue Position Line
indicates the current position in time in conjunction with the Ruler. The mouse can be used to select any range
of time from this area (CTRL+hold left mouse button) to be displayed in the Video and Spectrogram Windows)
⑭ Video Controls (Controls to Start/Stop video playback, turn HMD on/off (see VR Module), and change the
POV of the Video Window)
⑮ Color Gradient Scale (This color bar indicates the SPL represented by a specific color in the spectrogram.
The color-SPL relationship can be shifted by moving the slider to the right of the color bar in order to make
target frequencies more visible in the Spectrogram) (
⑯ Acoustic Image Hotspot (Typical hotspot in the Acoustic Image indicating the location of a high SPL of some
frequency) (
⑰ Drop Down Menu (This menu contains various options and extra module controls)
4.2 GUI Layout
4.2.1 Video Window (Center Screen)
The large center window shows the video with the overlaid gradient Acoustic Image. There are 3 view options
for the video: Mercator (default view), Spherical, and Globe projections. (The Planar Array Device can only
show the Mercator view)
While in Realtime mode, or when viewing recordings taken with the Audio/Visual Camera, the center of the
video can be repositioned; click-and-hold on the video window in order to drag to the left or right. Clicking the
button in the top right of the video window will put the panel into full screen mode, so it takes up the entire
application window. (this button is transparent to minimize obstruction of the scene and is difficult to see)
While the Mercator view is generally the best way to see an Acoustic Image, there are specific situations in
which other views can be preferred. In order to project a flat image, the Mercator view warps areas in the north
and south poles (top and bottom). Sound sources in the warped regions will still be overlaid accurately, but it
will be more difficult to translate those sources from the Video Window to the physical objects recorded. For
this reason, it is recommended that the Spherical or Globe projections be used when important objects in the
scene lie in the extreme top and bottom areas. (For example, when setup in a cramped location)
