With the Matrix Mixer, you can patch any soundcard input to any soundcard output with a single mouse click, even across different audio driver systems (DirectSound, WASAPI, ASIO) or to/from mAirList’s virtual sound card inputs/outputs (e.g. the encoder device).
The integrated REST server offers remote control through the HTTP protocol. You can send arbitrary commands through an HTTP POST request, and also use HTTP GET requests to access various information about the running mAirList instance, e.g. the current content of the playlist and the state of the players.
