Audio loop back test

To perform an audio loop back test, check "Audio loop back test" in either dialog box shown in Figure 5 and 6. In the test, your voice is sent back to you by the server.
This feature is very useful to check the connection status and adjust the volume and mic level.
When the check box is unchecked or the volume controller dialog box is closed, the mode is resumed to the normal communication mode.
Warning: During the test, your voice is not transmitted to other users and you don't receive audio signal from other users.

To check how the voice after the filter sounds, Audio loop back test is useful.
