PARAMETER_DOLBY_AUDIO_PROCESSING_DOLBY_ATMOS

Added in API level Baklava

static val PARAMETER_DOLBY_AUDIO_PROCESSING_DOLBY_ATMOS: String

Enable/disable Dolby Atmos.

Dolby Atmos creates a more immersive and realistic sound experience by adding a height dimension to surround sound. It allows sound to be placed and moved precisely around you, including overhead.

Note: To experience Dolby Atmos, you need content that has been specifically mixed in Dolby Atmos and a compatible sound system with upward-firing speakers or a Dolby Atmos soundbar.

Type: BOOLEAN

Value: "dolby_audio_processing_dolby_atmos"

PARAMETER_DOLBY_AUDIO_PROCESSING_SOUND_MODE

Added in API level Baklava

PARAMETER_DOLBY_AUDIO_PROCESSING_SURROUND_VIRTUALIZER

Added in API level Baklava

static val PARAMETER_DOLBY_AUDIO_PROCESSING_SURROUND_VIRTUALIZER: String

Enable/disable Surround Virtualizer.

Surround Virtualizer creates a virtual surround sound experience from stereo content, making it seem like the sound is coming from multiple speakers, even if you only have your TV's built-in speakers. It expands the soundstage and adds depth to the audio.

Type: BOOLEAN

Value: "dolby_audio_processing_surround_virtualizer"

PARAMETER_DOLBY_AUDIO_PROCESSING_VOLUME_LEVELER

Added in API level Baklava
