Tá tudo bem is a everyday Portuguese expression meaning everything is fine, and as a short audio it has circulated widely in Brazilian online culture as a calming, shareable reply. Like many WhatsApp audios, it works because it is instantly recognisable even without context: a brief spoken reassurance that can be dropped into chats, videos and memes whenever someone needs to hear that a situation is under control. Its staying power comes from that universal use, since stress, awkward moments and small disasters are always part of everyday conversation online.
