Transaural Sound

Transaural playback is a technique to render binaural sound with only two loudspeakers.

Transaural playback relies on the appropriate processing of a binaural signal to render the correct pressure signal at the listener's ears.

The 3D Sound Transaural option provides a way to achieve this processing through filters.

For example, the figure below shows cross-talk cancellation.
