O7A Panner - Hemisphere

Host Support

Host TypeSupport





There are various versions of this panner plugin. This version provides a control surface that maps directly onto the upper hemisphere of possible sound directions. You can click on the control surface to move the sound and holding some keys down changes how the sound is moved:

  • Use the "shift" key to select the lower hemisphere (so sounds are below rather than above).
  • Use the "alt" key to lock the elevation (so sounds move in a horizontal circle).

A hemisphere visualiser is available for use with this plugin. However, we generally recommend the standard panner, which has a control surface using the same rectangular layout as the standard O7A Visualiser.

The plugin is available in the O7A Core plugin library.

View Support

When used with O7A View Sync from the O7A 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.

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.
