How do I eliminate choppy audio being received by an LQ unit?
Choppy audio is usually the result of a port that has a network quality setting that is too high for the IP network. Choppy audio can usually be resolved by adjusting network quality on either the
transmitting or receiving devices.
For example, if the choppy audio is only on one receiving device, then the problem will probably be solved on that device. However, if the problem is on all devices except one, then the issue can probably be solved by adjusting network quality on the transmitting device.
Note:
If you want to resolve poor audio quality when using the 20 kHz audio feature, you may need to use the Custom network quality settings to keep the bitrate high at the same time as adjusting the jitter buffer. Do this on the device that is receiving choppy audio.
Network quality problems should be resolved on a per Channel basis.
Within a web browser, input the IP address of the required LQ device, or any device within a Link-Group into the address field in order to open the Core Configuration Manager (CCM).
Select the Assignments page from the top navigation bar.
Select the Channel with audio problems from the Channel selector on the right side of the page.
Click/touch the Local Audio Mix button within the Channel.
Click/touch the Network Settings.
Adjust the network quality slider bar.
Repeat step 6 until the choppy audio is minimized.
Note:
The jitter buffer setting is designed to buffer audio received to prevent loss if there is network jitter. Be aware that the jitter buffer selection will directly affect the latency. This is because the lower number in the jitter range represents the amount of time the LQ unit will buffer audio before delivering it to the port. A bigger jitter buffer setting will increase latency in milliseconds.
The Custom option within the Network Quality setting allows adjustment of the jitter buffer independent of other settings.
