Audio-Pis

The Audio-Pis are Raspberry-Pis with a Soundcard on top, accompanied with a Set of often used Audio-Adapters. They are used to stream Music from Lounges/Discos/Clubs via Wifi or Ethernet. They are using the Audio Injector Soundcard by FlatmaxStudios.

  3D Printed Cases

We are in the Process of designing and printing Cases for the Audio-Pis including the Soundcards. Here is a Rendering of the Beta, we'll tweet when the Case-Design is finished and tested and it will be publish here.

The Configuration of the Audio-Pis is managed from our Config-Management, but basicly it runs an ffmpeg-Command reading from alsa, encoding as Opus and pushing to our Icecast-Server. A second transcoding-ffmpeg, running on some server, is then generating the secondary mp3-stream from the primary opus stream.

They got a visual audio volume meter mounted which can be switched on/off and switch between input and loopback output sound.
