| As a simple test, just run the following two command lines where

| Im konkreten Beispiel wurden [[Audiovisuelles Zentrum HTW Dresden#Mikrofone Sennheiser | Mikrofone Sennheiser vom]] [[AVZ]] verwendet.
| |
|
| |
| Für die Aufnahme des Raumes ist die Sensibilität des Mikrofons auf ''-&nsp;6&nsp;dB'' (oder gar 0&nsp;dB) einzustellen. Das Mikrofone ist so sensibel, dass jedes kleinste Geräusch im Raum als Signal aufgenommen wird. Das bedeutet jedoch auch, dass in unmittelbarer Nähe keine Geräusche erzeugt werden dürfen. Das direkte Sprechen in das Mikrofon kann so nicht genutzt werden. Auch darf sich das Mikrofon nicht in Nähe eines Lautsprechers befinden, dass das aufgenommene Signal direkt ausgibt, denn es kommt zur Rückkopplung.
| |
|
| |
| Für die Aufnahme der Redenden ist die Sensibilität des Mikrofons auf ''-&nsp;42&nsp;dB'' (oder auch 36&nsp;dB) einzustellen.

|
| |
| Es sollte mit <code>pavucontrol</code> beim Reiter ''Eingabegeräte'' der Ausschlag kontrolliert werden.

|
| |
| ; Einstellung der Eingabe bei PulseAudio
| |
|
| |
| Bei <code>pavucontrol</code> gibt es den Reiter ''Eingabegeräte''. Dort sollten sich durch die Auswahl bei ''Anzeigen:'' ''All Input Devices'' alle nennenswerten Größen angezeigt werden lassen.
| |
|
| |
| :; Monitor of Internes Audio Analog Stereo: 100 %
| |
| :; Internes Audio Analog Stereo: 10 % (oder gar (höchstens) 13 %)

|
| |
| ; Einstellung der Ausgabe für die Lautsprecher (über den Anschluss für Kopfhörer) bei PulseAudio
| |
|
| |
| ; Einstellung der Ausgabe für den Stream (über beispielsweise [[#Darkice]]) bei PulseAudio
| |
|
| |
| Bei <code>pavucontrol</code> gibt es den Reiter ''Aufnahme''. Wenn eine Anwendung wie [[#Darkice]] läuft ist dort auch die Pegel und Möglichkeit zur Steuerung der verfügbar.

| |
|
| |
| Das geht selbstverständlich auch alles mit [[BSD]] ([[FreeBSD]]/[[PC-BSD]] usw.). Das hätte beispielsweise den großen Vorteil einfach [[Jail]]s als Virtualisierung nutzen zu können.<!-- Da müsste sich noch einmal der Aufwand zum Ausprobieren gemacht werden. -->

| ==== aus einem Hörsaal ====
| |
|
| |
| Es gibt verschiedene Wege.
| |
|
| |
| Wie gewohnt, kann [[WLAN]] verwendet werden. Bei der Bereitstellung von [[{{PAGENAME}}|Streaming]] sollte wohl aber die "festest" mögliche Anbindung genutzt werden, wobei eigentlich [[LAN]] zu bevorzugen wäre. Bei [[WLAN]] an unserer [[Hochschule]] sollte [[eduroam]] verwendet werden. [[VPN/WEB]] fällt natürlich schon allein wegen der Begrenzung zur Notwendigkeit der erneuten Anmeldung nach einer bestimmten Dauer heraus.
| |
|
| |
| Wenn [[LAN]] genutzt werden kann, was zu bevorzugen ist, muss wohl in den Hörsälen das sogenannte [[Hörsaalnetz]] genutzt. Um eine Verbindung zu allen anderen Rechner und dem Internet herstellen zu können, muss [[VPN]] für das [[Hörsaalnetz]] verwendet werden.
