Passthrough playback is used to play the audio without any 3D audio effects.
This section explains how to assign the passthrough settings to Materials and how to use them to create and preview Cues.

Material settings

This playback will not be affected by the 3D audio effect created by the binauralizer.
Therefore, a dedicated mixer (ASR rack) is used for the output.

To use passthrough playback, the appropriate setting must be assigned to the Material to be played.
This is done via the output port setting of the Material.
Assign the output port of the Material to "_passthrough" as follows:

Items	Settings
Output Port	Assign via _passthrough

Output Port for passthrough

When "_passthrough" is set in Material settings, a _passthrough dedicated to passthrough playback will be automatically created in the Output Ports of the Global Settings.

Passthrough-specific Output Port name
_passthrough

Note: When you register an ACF that contains the "_passthrough" output port in run-time, a mixer (ASR rack) for pass-through playback is be automatically created.

Settings for passthrough output ports

The output port settings for passthrough are:

Setting	Value	Description
Use a dedicated mixer	True (Locked)	Whether to use a dedicated mixer. Passthrough playback always uses a dedicated mixer (different from the main mixer).

Using a Material for passthrough in a Cue

When a Material with passthrough settings is dragged and dropped onto a Cue Sheet, a Cue compatible with passthrough playback will be created.
(Drag and drop directly onto a Cue to create a track compatible with passthrough playback.)
The output port setting of the Material will automatically be reflected in the output port setting of the track.
.

Note

Automatic registration of the Output Port for passthrough for a track
When you add a Material for passthrough to a track, the output port for passthrough is automatically added. However, if the waveform region is moved to another track, the output port of the new track will not be automatically updated.
Please assign the output port manually.
Setting the Output Port for Materials and Tracks
The Material referenced by the waveform region of the pass-through track must have "_passthrough" specified for its output port setting.
Note that if there is a difference in the output port settings between a track and the Materials it references, an error will occur during the ACB build.
