Stream settingsThis is a Mono/Stereo 2D scale that allows you to adjust the attributes of the sound when the sound is in Autonomous mode. It can be used to switch streams between Mono and Stereo, and set the Sample Rate for the stream.

-
Is the short of Monaural sound, means sound which was made from the mix of all audio signals in a system. The sound is routed through a single audio channel.
Since the speech engine reproduces only one voice, selecting Mono allows saving some CPU resources without decreasing the quality of the voice.
-
Is the short of Stereophonic sound. Stereo sound is the reproduction of sound, using two or more independent audio channels
-
Determines the overall bandwidth of the audio signal.
Higher sample rates produce higher quality audio at the expense of higher CPU utilization. Frequencies of about 1/2 the sample rate can be produced effectively, so to reproduce a frequency of 10 kHz, a sample rate of at least 20 kHz must be chosen.

In the Intercept mode, VCSD will display the attribute of the audio stream intercepted. For example, Internet audio programs normally use the Mono and 8000 Hz (or 11025 Hz) values, and these values will be displayed if you intercept such a program.
