Why voice notes come as Opus
Opus was built for speech over the internet. It keeps voices clear at very low bitrates, so a minute of a WhatsApp voice note is often only 100 to 200 KB. That makes it a good fit for messaging apps and calls, but music players support it less widely.
MP3 files are bigger, but they play in every app, car and device. Converting is the simplest way to keep a voice note outside the chat app it came from.
