7 Imaging
You can use the Logic Studio Imaging plug-ins to extend
the stereo base of a recording, and to alter perceived signal
positions.
These effects enable you to make certain sounds, or the overall mix, seem wider and
more spacious. You can also alter the phase of individual sounds within a mix, to
enhance or suppress particular transients.
The following sections describe the Imaging plug-ins included with Logic Studio:
 “Binaural Post-Processing Plug-in” on page 121.
 “Direction Mixer” on page 123.
 “Stereo Spread” on page 125.
Binaural Post-Processing Plug-in
Logic Pro allows you to route channel outputs through the Binaural Panner, a
psychoacoustic processor that is able to simulate arbitrary sound source positions
(including up and down information) by means of a standard stereo signal. The signal
that results from Binaural Panner use is best suited for headphone playback. You can,
however, use the integrated conditioning of the Binaural Panner to ensure a neutral
sound for speaker (or headphone) playback.
When using multiple Binaural Panners (on several channels), you should turn the
integrated conditioning off, and route the output of all binaurally panned signals to an
aux channel—in which you should 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.
