Working version of Opus Codec with limited options for Unity3d.
it does a local recording of the microphone, sending via unet, distribution on the server and playback on the clients.
add the script along with a network identity to a gameobject with one child gameobject, the child needs an audiosource, add the child as audioplayer to the script. add this gameobject as player to a network manager (each player needs his own instance).
or just use the provided example...
uses the c# wrapper from opusdotnetinvoke: https://opusdotnetinvoke.codeplex.com/
compiled the libraries on windows and osx from: https://www.opus-codec.org/downloads/
lgpl except for the code that is differently licensed.
hopefully someone can use this and make his improvements available to the public as well!
