Lua binding for RtAudio
$ luarocks install lrtaudio
Lua binding for RtAudio ( https://www.music.mcgill.ca/~gary/rtaudio/ ).
This binding enables Lua scripting code to open RtAudio streams and to
connect them with Lua audio processor objects for realtime processing.
Realtime audio processing of the Lua processor objects has to be implemented in
native C code.
