!> Transaural is only available in the Ultimate version of SPAT Revolution.

Although we said earlier that Binaurally encoded files are not compatible with stereo loud speaker systems, it turns out that in SPAT Revolution there is a way to play binaurally encoded signals on loud speakers if necessary. You can do this by transcoding a binaural stream into a Transaural stream either at the Input Transcoder stage of the Environment Setup graph or at the Master Transcoder stage.

The term Transaural refers only to the transcoding of binaural signals into loudspeaker-compatible signals. The reproduction mode is also known as “cross-talk cancellation” as it uses this very process to establish the loudspeaker-compatible signals.

!> To successfully achieve cross-talk cancellation, it is assumed that the listener will be placed at a particular position with respect to the loudspeaker pair, or the spatial information will not be properly perceived.

An optimum listening position such as that needed for Transaural decoding, is also known as ‘ the sweet spot ‘. It is a fundamental concept to be aware of as we move into the next section: Channel Based streams and panning algorithms.
