Frequently Asked Questions
What is Opus?
Opus is an open, royalty-free audio codec by IETF (RFC 6716). It handles both speech and music, adapts bitrate dynamically, and outperforms all other lossy codecs at low bitrates. It's the codec behind WebRTC, Discord voice, and WhatsApp calls.
Why is Opus at 96kbps instead of 128kbps?
Opus at 96kbps sounds as good as MP3 at 128kbps or AAC at 96kbps. It's exceptionally efficient — even 64kbps Opus is usable for music, where MP3 at 64kbps sounds terrible.
Does Safari support Opus?
Safari 15+ supports Opus in WebM containers. In OGG containers, Safari support is limited. For maximum compatibility, provide an AAC or MP3 fallback.
