Transaural
Although we said earlier that binaurally encoded files are not compatible with stereo loudspeaker systems, it turns out that in SPAT Revolution there is a way to play binaurally encoded signals on loudspeakers if necessary. You can do this by transcoding a binaural stream into a Transaural stream either at the Input Transcoder stage or at the Master Transcoder stage of the Setup page graph.
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. The loudspeaker pair need to be positioned as a regular stereo setup, Left at -30 degrees and Right at +30 degrees.
An optimum listening position such as that needed for Transaural decoding, is also known as the Sweet Spot (see Listener Position 4). It is a fundamental concept to be aware of as we move into the next section: Channel Based streams and panning algorithms.
