The function that corresponds to the status icon has been enabled or is available.
Description
This is a sound adjustment method. A higher network jitter contributes
to a better audio connectivity. In a conference, the lip movements and
voice of a speaker may not be synchronous. To solve this problem,
users can adjust the network jitter value.
When the terminal uses a wired network for video communications, it
is recommended that you use the default value of this parameter.
l Normal: By default, this option is selected.
l Loud: When the echo of a remote site is loud, the local site needs
to notify the remote site and the remote site should set
Environmental echo to Loud so that the echo of the remote site
can be canceled.
You can enable or disable echo cancellation for the audio sources from
MIC1 and MIC2 interfaces of the terminal. By default, this function is
enabled.
The setting of the music mode can take effect only when you set the
mode at the input end of the music. If the music mode is enabled at the
music input end, the music effect becomes better.
After a ringtone is selected, the terminal plays the ringtone when there
is an incoming call.
In stereo mode, you can adjust the balance of the left and right audio
channels by moving the slider.
To achieve different audio effects, adjust the equalizers by moving the
sliders.
