Field notes
The page describes two modes: one translates audio the user is listening to, while the meeting mode also translates the user’s microphone through a virtual mic. It lists macOS 14.2 or later and Windows 10 or 11, and says the captions arrive before the translated voice, with roughly three seconds of delay. The site says audio is discarded after streaming unless the user enables transcript history.
