Description [src]
abstract class Valent.MixerAdapter : Valent.Object {
parent_instance: ValentObject
}An abstract base class for audio mixers.
ValentMixerAdapter is a base class for plugins that provide an interface to
audio mixers and volume control. This usually means monitoring the available
input and output streams, changing properties on those streams, and selecting
which are the active input and output.
.plugin File
Implementations may define the following extra fields in the .plugin file:
-
X-MixerAdapterPriorityAn integer indicating the adapter priority. The implementation with the lowest value will be used as the primary adapter.
