Room
In SPAT Revolution, spatialization of virtual sources takes places inside Rooms. To enter a room and open its graphic editor environment, double-click on a room module in the Setup graph, or select a room tab from the Navigation bar.
When we enter a Room, we will see the 3D view and all the connected sources. Option related to the 3D view display are located in top menu. On the left side panel of the room editor, you get a list representation of each source with its index identification number. We can click on the Index number of each source, and the source parameters editor for that virtual source will appear.
Two special index items labeled as (R) REVERB and (M) OUTPUT appear fixed at the bottom of the left panel. By clicking on these, we then enter into two more parameter editors: one relating to the Artificial reverberation and one relating to the room output configuration and Listener Position editor.
Mutes and solos are manageable for all sources and for the entire room output from this index list. A solo clear button is available on the top of the source list. Clicking on it will reset all the solo of all rooms.
When you have more than one Room in your project, then the SOURCES switch at the top left of a Room editor can be handy, as it will show all sources from all Rooms in the same editor - allowing edition, mix, solo and mute management of all sources from one Room view.
Top bar menu
This menu allows changing what elements and how they are displayed in the 3D view.
Presence Infos:
Display the presence factor as a green vector. The brighter it is, the more present the source is. When off, green vector is no more drawn.
Real Pos. Infos:
In some very specific cases, the position of source in the DSP may be different that the one you set up. When on, the DSP position is also displayed.
To understand better what these two first options do, consult the “Understanding the mixing zones” section.
Source Infos:
Display the name of source even if it is not selected.
Speaker Infos:
Display the name of the speakers.
Scale:
Make the elements bigger of smaller for adjust ease of sight.
Shininess:
Change the shininess aspect of the graphical elements.
Lightness:
Change the brightness of the graphical elements.
Nebula Alpha:
Change the transparency of the Nebula spectral analyzer.
When set to 0%, Nebula does not take any resources at all.
Consult the “Nebula Spatial Spectrogram” section for more information.
Nebula Quality:
Configure the quality factor of nebula.
Changing this factor will significantly change the performances.
Speaker Alpha:
Change the transparency of the speakers.
Listener Alpha:
Change the transparency of the listener head.
Grid type:
Toggle between polar or cartesian grids.
Display Output:
Allows to display the nebula of a difference setup module, connected to this room. This is useful if you want to see the decoding of an ambisonic stream inside an ambisonic room for example.
Background color:
Change the background color.
View:
Choose if the 3D view is seen from:
- The top
- The front
- Or a split view : top and front
Display output drop-down
Located on top of the 3D view, the “display output” drop-down allows choosing which point of the signal path to display.
For example, working in an HOA room create 3D view that does not show any speaker. This is because of the very nature of how ambisonic work. But it also means that you cannot use Nebula in that kind of room. This is where this “display output” feature becomes handy. Instead of showing the actual HOA scene, it is possible to choose to look at the sound scene at the transcoding stage to see what happens with Nebula on the speaker array.
Room output parameters
Output list
This panel lists all the speakers used in the room (when set to channel based). It allows quick access to the speaker arrangement editor and to the compute function. Each output has a “test” button that sends the signal from the signal generator directly the routed speaker. The signal generator type and level are set in the Preferences page.
Listener
This panel gives access to the listening point. We can change its position, using the X, Y, Z parameters, and its rotations using Yaw, Pitch, Roll.
Protection Zone
This panel controls the behavior and size of the protection zone. By default, it is set to a diameter of four meters. Please check out the section named Understanding the mixing zone if you want more information about the protection zone. Note that the protection zone is attached to the listener position.
- Source fit speakers elevation
- Source over listener head
- Width
Efficiency Zone
This panel contains options related to the efficiency zone.
- Clamping behavior option (consult the Understanding the mixing zone section for more information)
- Depth - change the depth of the efficiency zone
- Trunc (available only for non-surrounding 2D speakers’ setup) - change the starting distance of the efficiency zone
Scaling
Distance
This parameter scales all the distance automation (OSC, plugins data and snapshots) by a manual factor. This factor is adapted automatically when editing the arrangement of the room.
Tracking
This parameter changes the scale of RTTrPM protocol data.
Background Image
This panel allows you to import a background image in SPAT Revolution and to position it in the 3D view.
