Table Notes:
*
In most circumstances, we recommend that you keep Echo Cancel enabled. Echo
Cancel helps optimize audio quality by reducing noise and cancelling echo (feedback).
However, we would 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 at the
bottom right of the Client console screen.
You can enable Echo Cancel again by clicking the icon [ ].For optimum audio quality,
we recommend that you:
 Enable Echo Cancel.
 Use USB audio devices with built-in echo cancellation.
**
Higher settings increase latency but can solve issue s with uneven (‘choppy’) audio.
Lower settings decrease latency but can cause audio quality issues. The performance
level of the PC is also a factor in determining the correct Audio Buffer setting.
