The Binaural Post-Processing Plug-in
The Binaural Post-Processing plug-in is available in aux and output channels. This plug-
in allows you to apply various compensation modes on a stereo bus or output (through
which several, or all, binaural signals are routed). This saves CPU power, and makes it
easy to switch between compensation modes:
The Compensation menu offers the following choices:
 Headphone FF - optimized for front direction: Setting for headphone playback, utilizing
free-field compensation. In this compensation mode, sound sources placed in front
of the listening position will have neutral sound characteristics.
 Headphone HB - optimized for horizontal directions: Setting for headphone playback.
Optimized to deliver the most neutral sound for sources placed on, or close to, the
horizontal plane.
 Headphone DF - averaged over all directions: Setting for headphone playback, utilizing
diffuse-field compensation. In this compensation mode, the sound will (on average)
be most neutral for arbitrarily placed, or moved, sources.
 Speaker CTC - Cross Talk Cancellation: Setting for speaker playback, which allows you
to play back binaurally panned signals via a stereo loudspeaker setup. Good spatial
reproduction is restricted to a limited range of listening positions (on the
symmetrical plane) between the speakers. If you choose the Speaker CTC setting
there is an additional parameter: CTC Speaker Angle. To achieve the best binaural
effect, enter the angle that your stereo speakers are turned towards the center
(listening position).
Note: When using the Binaural Post-Processing plug-in, the integrated conditioning of
individual Binaural Panners should be deactivated. This is done via the menu in the
extended parameters section of the Binaural Panner.
