About the formats
.mp3
MP3 is the universal audio format: every phone, car stereo, speaker and app plays it. It uses lossy compression, so a 3-minute song is a few megabytes.
.opus
Opus is a modern audio codec used by WhatsApp voice notes, Discord and WebRTC calls. It sounds great at low bitrates but many players and editors don't recognise .opus files.
