The Selector audio object allows you to switches between two sets of consecutive input channels and routes one of the sets to the output. While switching between the two sets, it applies ramping.
The Selector object has user configurable number of outputs which would imply that the number of inputs would be twice the output channels. The first n channels would be first group and n+1 to 2n channels would be next group.
For example: If the output configured is 2, then number of inputs would be 4. There would be 2 groups. 1 and 2 channels would form first group, 3 and 4 channels would be next group. The 2 output channels would be routed either from group 1 or group 2 based on selection.
Use case: This object can be deployed whenever a selected input channels are required in output channels in the audio pipeline.
Selector Properties
Below table describes about the Selector audio object properties and functionality.
| Properties | Description |
| # of Audio Out | Enter the number of output channels.
The number of inputs are always twice the number of output channels. |
| Display Name | Display the name of the Selector audio object in signal flow design. It can be changed based on the intended usage of the object. |
Mode
There are no mode available for Selector audio object.
Additional Parameters
There are no additional parameters available for Selector audio object.
Tuning Parameters
Below table describes the tuning parameters of Selector audio object.
The object exposes one variable for tuning, which is the ramp time.
| Parameter | Description | Type | Unit | Default | Range |
| Ramp time | The selected input channels are available at output channels within ramp time. | float | ms | 1 ms | 0 to 10000 |
| Selector Control | The object also has tuning parameter SelectorControl for switching between two groups. | Unsigned Long | None | 0 | 0 – channel 1 to m_NumAudioOut
1 – channel m_NumAudioOut +1 to m_NumAudioIn |
Control Interface
The Selector exposes one control, which is the actual switch that triggers switching between the two sets. Below table describes the control parameters of Selector audio object.
| Parameter | Description | Type | Unit | Default | Range |
| selector Val | This is the actual switch that triggers switching between the input groups similar to SelectorControl of tuning parameter. | unsigned integer | None | 0 | 0 – channel 1 to m_NumAudioOut
1 – channel m_NumAudioOut +1 to m_NumAudioIn |
Native Panel
Selector audio object does not support native panel.
