Audio settings

When you press and hold down the left button, in the applet below, the audio device starts to record audio from your microphone. You should adjust the input gain until you have a good signal which does not extend beyond the red lines. You should also listen to the recording in order to adjust the play volume to a comfortable level.
Use the sliders above to adjust input gain and play volume.
You can also use the audio control program of your workstation (necessary for Windows and SGI).
