Monitor incoming Shoutcast/Icecast streams for activity, and when they become available, re-broadcast them instantly.
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 Aircheck Recorder records audio from a soundcard input. It can be paused and unpaused using fader start commands coming from any remote control input, so you can turn it on and off with your red lights to only record when the mics are on. You can run up to 8 Aircheck Recorders within a single playout instance.
The File Recorder, introduced in mAirList 6, is another recording facility that is designed for timed recordings and rebroadcasts of live shows.
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.
