About:
Opus is a lossy audio coding format designed for efficient speech and general audio transmission over the internet. It combines technologies from the SILK and CELT codecs to deliver high-quality, low-latency audio at various bitrates. The format is standardized by the IETF and is widely used in real-time communication applications like VoIP and video conferencing.
Key Features:
  • Low latency suitable for real-time communication
  • Supports both speech and music at bitrates from 6 kbps to 510 kbps
  • Royalty-free and open standard (IETF RFC 6716)
Use Cases:
  • VoIP and telephony applications
  • WebRTC-based video conferencing
  • Streaming low-latency audio over the internet
Alternatives:
  • AAC – Proprietary, higher complexity, better for high-fidelity music storage
  • MP3 – Older format, higher latency, less efficient for speech at low bitrates
