What is the minimum bitrate scalability Opus supports, allowing fine-tuning for rapidly fluctuating network conditions?
Answer
About 6 kb/s
Opus was engineered for extreme bitrate scalability to serve as a universal codec suited for the modern, often unstable, internet. Its operational range allows fluid scaling from a very low floor of approximately 6 kb/s up to a maximum of 512 kb/s. Crucially, this scaling capability is extremely granular, supporting increments as small as 0.4 kb/s. This fine control is vital for interactive applications where bandwidth availability can fluctuate rapidly, allowing the codec to adjust its quality precisely to match current network capacity without necessitating a full stream reconfiguration.
