Announcing Dolby Audio for High Performance Audio in Microsoft Edge (opens in new tab)

You don't want browsers to add features that you personally have an unscientific bias against?

This isn't innovation. AC-3 is almost 20 years old, and wasn't very good even for the time (it was designed for high-bandwidth optical discs). Dolby Digital Plus is an extension whose primary purpose is to extend their patent licensing regime.

Innovation would have been using Opus (full disclosure: I'm one of the authors of Opus).
