Why OPUS though? There's dedicated audio codecs in the VoiP/telecom industry that are specifically designed for the best size/quality for voice call encoding.
- pipo234 1y agoOpus is one of those codecs. Older codecs like g711 have better latency and steady bitrate, but they compress terribly. (Essentially just bandwidth and amplitude remapping). Opus is great for a lot of things and realtime speech over sip or webrtc is just one.

- andrepd 1y agoOpus pretty much blows all those codecs out of the water, in every conceivable metric. It's actually pretty impressive that a media codec is able to universally exceed (or match) every previous one in every axis. Still, it's based on ideas from those earlier codecs of course :)
