improves received audio when packet loss occurs in the network.
PLC is enabled by the SET_AUDIO_PLC System Flag in system.cfg
— PLC for Audio is supported with MPM+ and MPMx cards only.

compression.

— Auto Brightness is supported with MPM+ and MPMx cards only.
— Auto Brightness only increases brightness and does not darken
video windows.
• Audio Clarity - improves received audio from participants connected
via low audio bandwidth connections, by stretching the fidelity of the
narrowband telephone connection to improve call clarity.
