The Audio plug-in allows a designer to configure audio channels. The Audio plug-in can be applied to any Container. The plug-in has three different audio clip mixing modes, and each mode panel has a test function.

Note: This plug-in is located in: Built Ins -> Container plug-ins -> Global

This page contains the following topics and procedures:

Default Mode

The Default mode uses the Channel settings stored in the clip. For example FrontLeft and FrontRight are mixed to the aliases FRONT_LEFT, FRONT_RIGHT and so on.

If Viz Engine is configured with fewer channels, Viz Engine mixes the remaining clip channels according to the channel geometry. For example if Viz Engine only has stereo configured, but the clip used has 7.1 surround sound, Viz Engine mixes LeftBack and LeftMiddle to FRONT_LEFT and so on.

The Pan slider uses audio aliases when adjusting the volume of the left and right speakers. This is valid for multichannel configurations as well. If the slider is moved to the right in a 7.1 configuration LeftBack, LeftMiddle and LeftFront are muted. The Volume field controls the overall audio volume of all clip channels.

FX Mode

In the FX mixing mode Viz Engine mixes the clip in relation to the listener position which can be defined in the fields X and Y. Viz Engine takes the channel geometry into account. The Volume field controls the overall audio volume of all clip channels.

Manual Mode

In Manual mixing mode it is possible to enter the Out Channel alias for every clip channel. The mask can hold more than one channel. This allows the mix of every clip channel to an arbitrary amount of out channels. The Volume field controls the overall audio volume of all clip channels.

The syntax for the string is as follows:

CHANNEL_ALIAS%VOLUME+CHANNEL_ALIAS%VOLUME…

or

[CHANNEL_ALIAS%VOLOUME]+

Example: [FRONT_LEFT%0.5]+
