I just got word that the MP3 format is practically royalty-free, when the last (known and not extended) patent expired on April 16th. We could have interesting developments in the coming months. https://en.wikipedia.org/wiki/MP3#Licensing.2C_ownership_and_legislation
@BreadMaker Please don't build on #MP3 just because the patents have expired. #Opus really does a better job. #SecondSystemEffect
