Table Notes:
*
In most circumstances, we recommend keeping Echo Cancel enabled. Echo
Cancel helps optimize audio quality by reducing noise and cancelling echo
(feedback).
However, we advise disabling Echo Cancel when using:

Some Active Headsets (headsets with built-in sidetone or noise
reduction).

The Concert Client on a low-performance CPU (for the minimum
recommended standard see 1.1 System requirements).
When Echo Cancel is disabled, the flashing Echo Cancel icon [ ] is displayed:

In the bottom, right of the Client console screen.

At the top of the Intercom Panel.
You can enable Echo Cancel again by right-clicking the icon [ ] and selecting
Enable Echo Cancel.
**
Higher settings increase latency but can solve issues with uneven (‘choppy’)
audio. Lower settings decrease latency but can cause audio-quality issues. The
performance level of the Mac is also a factor in determining the correct Audio
Buffer setting.
