AudioUsageType

Enum for Audio Usage Types

Each value determines a different usage type of the playback stream. The usage type affects:

• Audio focus behavior (priority, ducking)
• Volume curve mapping
• Routing decisions
• Interaction with other audio streams

Possible Mappings

Usage Type	Value	Focus Priority	Focus Behavior	Volume Behavior	Typical Application
USAGE_NONE	0	Lowest	No focus management	Default curve	Fallback when usage is unknown
USAGE_MEDIA	1	Standard	Can be ducked by higher priority	Media curve	Music, video players
USAGE_COMMUNICATION	2	High	Ducks other streams	Communication curve	VoIP, calls
USAGE_ALARM	3	High	Ducks media	Alarm curve	Alarm clock
USAGE_NOTIFICATION	4	Low	Can be ducked	Notification curve	System notifications
USAGE_ACCESSIBILITY	5	High	Ducks most other audio	Accessibility curve	Screen readers
USAGE_ANNOUNCEMENT	6	Medium	Can duck lower priority	Announcement curve	Navigation prompts
USAGE_NAVIGATION	7	High	Ducks media	Navigation curve	GPS apps
USAGE_RING	8	High	Ducks media	Ring curve	Phone ringtones
USAGE_VOICE_ASSISTANT	9	Highest	Ducks or pauses others	Assistant curve	Voice assistants
USAGE_SYSTEM	10	System	System priority	System curve	System sounds
USAGE_VOICE_RECOGNITION	11	High	Exclusive focus	Recognition curve	Voice input
USAGE_VOICE_PROMPT	12	High	Ducks others	Prompt curve	System voice prompts
USAGE_SPOKEN_WORD_CONTENT	13	Standard	Similar to media	Speech curve	Audiobooks
USAGE_TEXT_READER	14	High	Ducks media	Reader curve	Text-to-speech
USAGE_FLASH_BRIEFING	15	Standard	Can be ducked by higher priority	Media curve	Flash Briefing, video players

Notes:

• Higher priority audio usage types can interrupt lower priority ones
• When interrupted, streams can be:
  • Ducked (volume reduced)
  • Paused
  • Stopped
  • Released
• Focus can be explicitly managed using
