The Control Mixer audio object provides a mechanism to mix and route control signal from input to output. The mixer sums values from selected control inputs and pushes the sum to the output. Numbers of inputs and outputs are configurable via GTT. It enables N inputs to be connected to M outputs which is configurable ranging from 1 to 254. If there isn’t any input signal associated with output, the output wouldn’t be changed.
The non-weighted mode with one connected control input output channel. Connection can be changed from state variable window in GTT during tuning, but its impact will be visible once input at that control pins is changed.
It takes control signals as inputs and emits control signals as outputs. Many inputs can also be connected to one output and output can be left unconnected also. It can copy any input to arbitrary number of outputs (from 0 to number_of_outputs). It means that some inputs can be copied to multiple outputs, or some inputs can be cut (not used further in the pipeline). On the other hand, one output can have at most single input connected to it. Below picture illustrates the idea.
Control Mixer Properties
Below table describes about the Control Mixer audio object properties and functionality.
| Properties | Description |
| Display Name | Display name of the control mixer audio object in signal flow design. It can be changed based on the intended usage of the object. |
| Object Mode | Based on the weighing factor of the control inputs to be mixed, the Control Mixer works in two different modes.
|
Mode
The Control Mixer supports in two modes.
- Non-weight mixer(default)
- Weight mixer
Additional Parameter
| Parameter | Description | |
