Apple Logic Pro 9 - Manual (Page 787)

• If set to Spherical, the results are placed on a virtual sphere. If it helps, imagine the
sphere as a virtual head. When the “direction puck” is placed in the top half of the
circular plane, the sound is in front of the listener. As the direction puck is moved toward
the lower half of the plane, the sound passes up, and over your head, and ends up
behind you.
4 Set the size of the plane or sphere by doing one of the following:
• Drag the Size field value up or down.
• Double-click the Size field, then type a new value.
• Option-click the Size field to reset it to its default value (1.50m).
5 Click the Doppler button to enable or disable the Doppler effect.
6 Select the Diffuse-Field checkbox in the Extended Parameters area to ensure a neutral
sound for headphone playback, utilizing diffuse-field compensation.
Note: When using multiple Binaural Panners on several channel strips, turn this option
off and route the output of the Binaural Panners to an aux channel strip, in which you
insert the Binaural Post-Processing plug-in. The Binaural Post-Processing plug-in allows
you to apply diffuse-field compensation to all Binaural Panner outputs at once, saving
CPU power.
7 If in Planar mode, use the Extended Parameters sliders to control the vertical offset and
tilt of the circular plane—watch the 3D image when changing them to get a clear idea
of their functions.
