Station-IC: What is the latency of Station-IC?

Question:
What is the latency of Station-IC?


Answer:
Station-IC audio latency is measured on a controlled LAN.

Eclipse systems allow users to select and configure (Eclipse only) Network Connection Presets.
These presets adjust jitter buffers, enable forward error correction and encryption, depending on the selection, to make connectivity over different networks to enable connection reliability over the available QoS .

Please note:
The above audio latency was measured on a local network with user selected network connection presets which increased latency with audio processing, encryption and Forward Error Correction for network resilience. Measurements are averages due to inline adaptive Echo Cancellation and Silence Suppression.
Final latency performance will be heavily dependent on configuration, computer, audio peripherals and network.


Practical Comparison:
Using the same test methods, Agent-IC and Microsoft Teams were measured for comparison.
