The exact origin of this recording is not documented, so it is best treated as a general-purpose greeting clip rather than a quote from a known show or creator. The phrase '早安大家' is one of the most common Mandarin morning greetings, heard daily in classrooms, offices, livestream chats and family group messages across the Chinese-speaking world. Short voice greetings like this one circulate widely as reaction sounds and chat stickers for opening conversations, which is why the clip works so well as a universal, friendly hello for videos and streams.
