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 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. AV Meter They got a visual audio volume meter mounted which can be switched on/off and switch between input and loopback output sound. https://c3voc.de/wiki/hardware:audio-pis:av-meter hardware/audio-pis.txt Last modified: 2020/08/25 10:30by derpeter
