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-MixerAdapterPriority

    An integer indicating the adapter priority. The implementation with the lowest value will be used as the primary adapter.
