This plugin reflects the entire O3A soundfield in a "mirror" plane through the centre of the room. For instance, it can swap sounds on the left with those on the right.
Azimuth and elevation controls are provided to control the direction in which the mirror plane is placed. For instance, setting the azimuth to +90 and the elevation to +0 points sets the direction to the left. This mirror will transfer sounds on the right over to the left and vice versa. Similarly, setting the direction to the front transfers sounds at the front to the back and vice versa. Technically, this direction is the "normal" to the plane.
The direction can be set using the azimuth and elevation controls, or the control surface. The mirror plane is indicated on the surface by a dotted line and the direction by crosshairs, which can be changed by clicking with the mouse.
There are labels on the control surface to help you find left, right, above etc. However, if this still does not make any sense, you might want to see our page on the O3A Visualiser which lays out its viewing region in the same way.
The plugin is available in the O3A Manipulators plugin library.
When this option is available, a 'View' button appears at the top right of the plugin's user interface.
When this is pressed, the plugin is connected to the View or ViewVR application and is displayed there.
The current direction is shown using a cross.
Hold the left mouse button to set the azimuth and elevation.
The current direction is shown using a beam and cross.
Hold a VR controller trigger to set the azimuth and elevation.
Azimuth and Elevation control the direction towards the mirror plane.
Azimuth is the horizontal angle, between -180 to +180 degrees, measured anticlockwise (left) from the front. Elevation is a vertical angle between -90 and +90 degrees, measured with positive upwards and 0 on the horizontal.
For instance, the direction for azimuth +90 and elevation +45 can be found by turning 90 degrees to the left and then looking up by 45 degrees.
