Sound
The front area of our space is equipped with a powerful sound system. Seven wall-mounted speakers (JBL control), accompanied by a subwoofer beneath the stairs are wired to four amplifiers located in the server room.
PulseAudio
Use PulseAudio for playback from your machine or MPD/MPlayer/XBMC.
There are three output devices available:
- Upmix for background music
- Hackcenter for showing stuff in the back of the room, only the speaker near the TV is used
- Presentation for showing stuff in the lounge, using the three speakers at the screen
- Surround for pass-through of multi-channel audio (theatric)
For example, use the following command to create a remote sink on your machine:
pacmd load-module module-tunnel-sink server=pulse sink=hackcenter
Then, switch the desired stream to the new sink. Use can use pavucontrol for that.
Warning: Remember to lower your playback volume before switching outputs to prevent damaging everyones ears.
Um vom lokalen Capture-Device an den Mischer zu streamen, nutze folgendes Kommando:
parec --latency-msec=50 | pacat --latency-msec=50 --server=pulse
ALSA
PulseAudio outputs over the usual ALSA devices. The default mixer settings are balanced for nice background sound both in the Lounge and in the Hackcenter. To override these, use the PulseAudio mixer interface.
Musik
Zum Musikhören: Die Verstärker über http://dorfmap/ einschalten. Die Anlage ist an den Multimedia-Server angeschlossen, auf dem ein MPD als Jukebox läuft.
Anschließend kann die Musik zum Beispiel über unser Web Interface unter http://mpd/ gesteuert werden.
Da das Web Interface auf Einfachheit ausgelegt ist, möchtet ihr evtl. einen MPD Client auf eurem Gerät nutzen. Eine umfassende Liste gibt es unter http://mpd.wikia.com/wiki/Clients
- Für Android sind MPDroid und MPD Control ganz gut.
- Für PCs (Linux und Windows) taugen Cantata und GMPC
- Das Apple-Universum hat leider wenig Liebe für MPD übrig.
