 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.
+===== Software =====
+The Configuration of the Audio-Pis is managed from our [[https://github.com/voc/cm|Config-Management]], but basicly it runs an [[https://github.com/voc/cm/blob/5324e06/ansible/roles/audio-pi/templates/audio-ingest.sh.j2|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.
+===== AV Meter =====
+They got a visual audio volume meter mounted which can be switched on/off and switch between input and loopback output sound.
