6.6 Source

The next row transforms the inputs into virtual objects according to their configuration. This is what needs to happen so that a virtual Source appears in a virtual room. If you try to connect an input directly into a Room, Spat will always put a Source module in-between.

The Source modules are where you set a descriptive Name of each virtual object. It’s a good idea to do that, as things can get busy inside the Rooms. You can also adjust the overall gain of a Source here no matter how many channels it might have. The Source modules are also important for parameter automation using the Spat Send plug-in, and also in the case of external OSC control.

External software needs to know how to identify virtual objects, and that will done using an Index number rather than a name. This Index number refers to one of these Source modules, numbered from left to right which in turn, becomes a Virtual sound emitting object in the Virtual Room. When working in a Channel Based Room outputting to an n.1 surround speaker arrangement, each source will additionally acquire an individual LFE Send. This dial will be available in the Source Parameters inside the Virtual Room editor, and also mirrored here as a fader directly in the Source modules. LFE Send controls how much of this source’s signal is mixed into the LFE channel at the output.

★ When using a BlackTrax positional tracking system a Tracking index can be assigned to a virtual source directly from the Source module
