The following image displays the tracks of an Ambisonic Ambience Sci-Fi subproject. These projects are arranged with Layers that form ambient loops.
Track colors vary by layer, and the track names and colors are used similarly throughout the Ambience Sci-Fi subprojects.
The following image shows the Composite tracks in white. Note that the Stereo composite is routed to the parent Composites track, while none of the other composite tracks are routed to an output. This is the default configuration of all the Ambience collection ambisonic projects. Depending on your monitoring system and your needs, you can unmute a desired composite track and route it to the parent Composites Track. Don’t forget to either mute the Stereo Composite or disconnect its routing to the Composites Track. The Composites track is in turn routed to the Master track, which is configured for 16 channels. The black subtracks of the composite tracks have an IEM plug-in configured to decode the output of the main mix to the desired multichannel output configuration.
The following image shows the routing of the Stereo composite track to its parent Composites track.
The following image shows the IEM plug-in decoding the third-order main mix to stereo and its parent composite track, Stereo, routed to its parent, Composites.
If you unmute any Composite track, select one or more regions, and then render them, the selected regions are rendered to the Rendered folder in an automatically generated subfolder named after the Composite track name and configuration. The names of the files are the same, but they contain metadata that indicates the channel count.
The following image shows some automatically generated folders.
The Basic Layer is the defining characteristic of an ambience. In the Ambience projects, the item source files are Octo 3D ORTF recordings split into four-channel files that represent positions above or below the height of the listener’s head (Lo is below and Hi is above). Depending on the type of ambience, there is usually a Modulation Parameter track with one or more envelopes to control characteristics of the sound.
The Objects subprojects also have Basic Layer tracks. They have items with mono or stereo source files, which are not mixed using ambisonics.
Depending on the ambience, there might be a Details Layer that has similar characteristics to the Basic Layer.
The item source files for these are Octo 3D ORTF recordings split into four-channel files that represent positions above or below the height of the listener’s head (Lo is below and Hi is above).
Depending on the type of ambience, there is usually a Modulation Parameter track with one or more envelopes to control characteristics of the sound.
The Objects subproject has layers related to sounds designed to be used as point source, localized sound objects that might occasionally play in an ambience design, adding dynamic elements.
The ambisonic encoding is performed by the IEM MultiEncoder plug-in. The tracks are positioned at the top of the hierarchy of Loop Layer tracks. Their output is routed to the composite tracks, where the third-order main mix is decoded to multiple track configurations simultaneously. In most cases, it is not necessary to make any adjustments to these tracks.
The subprojects have two Reverb tracks, one for each set of loop tracks, named Loop 1 Reverb and Loop 2 Reverb. The Loop 1 and Loop 2 tracks are configured with sends named Reverb 1 and Reverb 2 respectively. The Loop Reverb tracks have multiple plug-ins that are controlled by Modulation Parameters with envelopes to control the gain and size of the reverb.
Each Reverb Loop track has the following plug-ins:
The audio received by the Reverb Loop track is first gain controlled, then encoded to third-order ambisonics, and then processed by the Multi EQ and FDN Reverb. You can also control gain after the EQ and Reverb processing. Some plug-in parameters are controlled by the Gain and Size envelopes.
