System Audio Live Captions on Mac

System audio live captions matter when the sound you need to follow is already playing on your Mac.

Caption is designed around a unified capture path so system audio, microphone input, and app output can belong to the same caption workflow.

When this helps

• Remote calls and meetings
• Training videos and demos
• App audio or browser playback
• Situations where replaying later is too slow

Why live captions first

Live captions are for understanding now. Offline subtitles are for revision and delivery later. Caption keeps both in the same product so the session does not split into unrelated tools.
