Public Methods

void AudioAdmin (StreamVolumeManager * volume_manager, PolicyActionReporter * policy_action_reporter, ActivityDispatcher * activity_dispatcher, ActiveStreamCountReporter * active_stream_count_reporter, async_dispatcher_t * fidl_dispatcher, BehaviorGain behavior_gain)

Constructs an |AudioAdmin| from a |BehaviorGain| and |GainAdjustment|.

The |BehaviorGain| provides the target gain_db values to use when triggering behaviors between

usages, simply mapping each behavior to a relative gain value. The |GainAdjustment| is simply

an interface that this object will use to apply the target gain values in |BehaviorGain|.

If no parameter is provided for |BehaviorGain|, a default behavior will be used.

|gain_adjustment| must be non-null.
