About the formats
.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.
.aac
AAC is the audio codec behind iTunes, YouTube and most MP4 videos. It sounds better than MP3 at the same bitrate, but bare .aac files aren't accepted everywhere.
