Description

This O3A panner takes a mono sound and places it in a particular direction in a 3D O3A mix.

There are various versions of this panner plugin, but this is our favourite. This version uses more screen real estate than the "classic" version but is typically easier to use, particularly if you are just starting out with this way of doing things.

As well as azimuth and elevation dials, there is a control surface which can be used to visualise the current direction (indicated by the crosshairs). This direction can also 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 Core plugin library.

View Support

When used with O3A View Sync from the O3A View library, this plugin can be connected to the separate View or ViewVR applications.

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.

Controls

Controls: Azimuth and Elevation

Azimuth and Elevation control the direction in which the input is placed in the 3D audio scene.

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.

It may help to experiment with the control surface to get used to this way of doing things.
