Opus vs MP3
Opus · Opus Audio
Opus is a modern, royalty-free audio codec that beats MP3 and AAC at low-to-mid bitrates — it's the default for WebRTC, Discord and YouTube audio. Excellent for voice and music, though some legacy players still can't open it.
MP3 · MPEG-1 Audio Layer III
MP3 is the universal lossy audio format — it plays on practically every device, app and car stereo ever made. Files are small and quality at 192kbps+ is transparent for most listening.
