Calibration
When using the RB-AEC for the first time, the unit must first be calibrated
to suit the environment in which it will be used. Using the webserver, select
the ‘Config’ tab.
1. Select the desired sample rate.
2. Measure the distance between the speaker and microphone in
centimetres. Halve this number and enter it here. Example: For a
distance of 100cm, enter 50. Otherwise leave this value at zero.
3. Tick the box labelled ‘Load Saved Coefficients on Startup’. This will ensure
that any saved coefficients are used next time the unit is switched on.
4. Set the presenter’s(Far End) silence detect threshold. Levels below this
value will disable the canceller.
5. You also have the option of enabling the noise gate, setting the threshold
and changing the release time.
6. Submit your settings
7. For calibration, ensure the control room is silent and speak into the
presenter’s microphone while monitoring using the presenter’s earpiece
for around one minute or until the echo has subsided to a satisfactory
level.
8. Save your coefficient values so they can be used as a starting point for
next time the RB-AEC is used.
