Using Binaural Panning in the Mixer
Binaural panning allows the direction of a signal source to be recognized—in front,
behind, above, below, and to the left or right of the listening position—by means of a
standard stereo signal. This emulates human hearing, which is capable of interpreting
positional information—where a sound is coming from—despite the fact that only two
“receivers” (your ears) are used to capture the sound. Use binaural panning as part of
your audio signal mix to place individual sound sources at different spatial positions. For
background information, see Binaural Hearing—Binaural Recording—Binaural Panning.
In Logic Pro, it is possible to set the channel strip output to Binaural. You can then use
the Binaural Panner window to position the signals on the panning plane.
The signal that results from Binaural Panner use is best suited for headphone playback.
You can, however, process the Binaural Panner output with the Binaural Post-Processing
plug-in. This enables you to play back the binaural pan effect through loudspeakers. For
more details, see Using the Binaural Post-Processing Plug-in.
To open the Binaural Panner window
1 Choose Binaural from a channel strip’s Output slot pop-up menu (on mono or stereo
channels).
The Binaural Pan control replaces the Pan/Balance control on the channel strip.
