Opus and WAV explained
Opus is the current state of the art for lossy audio, and the codec behind most voice calls you make over the internet. It performs well across an unusually wide range, from 6 kbps speech to transparent music.
WAV stores uncompressed PCM audio — the raw samples, exactly as captured. A stereo CD-quality minute is roughly 10 MB, which is the price of having no compression whatsoever.
- Where Opus files come from
- Voice and video calls, modern podcast pipelines and WebRTC.
- Where WAV is used
- Recording sessions, sample libraries and audio editing.
