Description [src]
abstract class Valent.MixerAdapter : Valent.Extension {
parent_instance: ValentExtension
}
An abstract base class for audio mixers.
ValentMixerAdapter
is a base class for plugins that provide an interface to

input and output streams, changing properties on those streams, and selecting
which are the active input and output.
