Audio artifacts at higher frequencies when live streaming with Opus 2020-10-06 20:55:25 I've seen several folks post about audible artifacts at higher frequencies with encoding with Opus. (One suggestion was to use a low-pass filter around 15,000).I'm working on live streaming concerts from my studio to my website, using a WebRTC company in British Columbia. Video encoder is VP8, audio is Opus. Works fine, except for the upper registers of the guitar - these sound distorted, almost like they are underwater. I've heard the same thing on another provider (OpenTok) using WebRTC and the Opus encoder. It's a bit nasty.I'm unsure whether this can be addressed by implementing something in the WebRTC code (EQ or low-pass filter) or perhaps in the Opus encoder itself. I wanted to see what anyone might suggest for addressing this. Thanks so much!!
