tl;dr: Opus encoding just got 20% faster on desktop Chromium by turning on AVX2 vectorization in libopus. Vectorization means one instruction doing the same arithmetic on a whole vector of values at once instead of one at a time. Codecs spend their hot loops running identical math across long buffers of samples, exactly where vectorization […] The post Vector Vibing to speed up Opus encode by 20% appeared first on webrtcHacks.
