What is the advantage of the Opus codec?

• A. It adapts across bitrates and network conditions, providing good quality and resilience.
• B. It requires a fixed bitrate across networks
• C. It is restricted to video only
• D. It uses the highest CPU load among common codecs

Answer: (A)

Opus’ main advantage is its ability to adapt across bitrates and network conditions, delivering consistently good quality and resilience. It is designed for real-time audio and can scale from very low to very high bitrates, adjusting on the fly to available bandwidth and latency. This adaptability, combined with robust features like low latency and effective packet loss handling, keeps audio clear even as network performance fluctuates.

The other statements don’t fit: the codec does not require a fixed bitrate, it is an audio codec (not restricted to video), and it’s not known for imposing the highest CPU load among common codecs.
