Microphone input gain:
It is necessary to find the optimum gain between -15dB to
+15dB that transmits the best audio for listening.
Audio type:
Advanced Audio Coding (AAC) is a wide band audio coding algorithm
that exploits two primary coding strategies to dramatically reduce the amount of
data needed to convey high-quality digital audio. Select a higher bit rate number
for better audio quality.
AAC bit rate:
Select an AAC bit rate from the drop-down list. Higher bit rate means
higher audio quality but it takes more network bandwidth to transmit.
G711 bit rate:
Select an G711 bit rate from the drop-down list. Higher bit rate
means higher audio quality but it takes more network bandwidth to transmit.
