What OPUS and MP3 files are

OPUS

Opus is an open, royalty-free audio codec standardized by the IETF in 2012 for speech and music over the internet. It sounds better than MP3 or AAC at low bitrates and is used in WebRTC calls, Discord voice chat and WhatsApp voice messages, but Safari only began playing .opus files in 2025.

MP3

MP3 is the most widely used compressed audio format. It shrinks recordings to a fraction of their original size while keeping the sound quality most listeners expect, which is why it plays on virtually every device and app.
