}Variants§
CreateAudioRenderer
Creates an AudioRenderer which outputs audio to the default device.
CreateAudioCapturerWithConfiguration
Creates an AudioCapturer according to the given requirements.
pcm_stream_type sets the stream type of the stream to be delivered.
It causes the source material to be reformatted/resampled if needed
in order to produce the requested stream type.
usage is used by Fuchsia to make decisions about user experience.
See AudioCaptureUsage for more details.
configuration must be initialized to a variant, or no capturer
can be created.
Fields
stream_type: AudioStreamTypeconfiguration: AudioCapturerConfigurationaudio_capturer_request: ServerEnd<AudioCapturerMarker>control_handle: AudioCoreControlHandleCreateAudioCapturer
Creates an AudioCapturer which either captures from the current default audio input device, or loops-back from the current default audio output device based on value passed for the loopback flag.
EnableDeviceSettings
SetRenderUsageGain
Sets the gain for this render usage. By default, all render usages are set to Unity (0 db).
SetRenderUsageGain2
Sets the gain for this render usage. By default, all render usages are set to Unity (0 db).
SetCaptureUsageGain
Sets gain for this capture usage. By default, all capture usages are set to Unity (0 db).
SetCaptureUsageGain2
Sets gain for this capture usage. By default, all capture usages are set to Unity (0 db).
BindUsageVolumeControl
Binds to a volume control protocol for the given usage.
BindUsageVolumeControl2
Binds to a volume control protocol for the given usage.
GetVolumeFromDb
Queries the volume percentage [0, 1] that maps to a gain_db value for a particular
usage. This is the same mapping as used by the VolumeControl from
BindUsageVolumeControl.
GetVolumeFromDb2
Queries the volume percentage [0, 1] that maps to a gain_db value for a particular
usage. This is the same mapping as used by the VolumeControl from
BindUsageVolumeControl.
GetDbFromVolume
Queries the decibel value that maps to a volume percentage [0, 1] for a particular usage.
This is the same mapping as used by the VolumeControl from BindUsageVolumeControl.
GetDbFromVolume2
Queries the decibel value that maps to a volume percentage [0, 1] for a particular usage.
This is the same mapping as used by the VolumeControl from BindUsageVolumeControl.
SetInteraction
Sets how audio_core handles interactions of multiple active streams simultaneously. If
streams of Usage active are processing audio, and streams of Usage affected are as well,
the Behavior specified will be applied to the streams of Usage affected.
SetInteraction2
Sets how audio_core handles interactions of multiple active streams simultaneously. If
streams of Usage active are processing audio, and streams of Usage affected are as well,
the Behavior specified will be applied to the streams of Usage affected.
ResetInteractions
Re-initializes the set of rules that are currently governing the interaction of streams in audio_core. The default behavior is ‘NONE’.
Fields
control_handle: AudioCoreControlHandleLoadDefaults
Re-loads the platform policy configuration. Falls back to a default config if the platform does not provide a config.
Fields
control_handle: AudioCoreControlHandle_UnknownMethod
An interaction was received which does not match any known method.
Fields
This variant is marked as non-exhaustive
