User interface

Voice Activity Detection (VAD) samples the peak amplitude detected at the microphone every 30 ms and converts it to dB. If the sampled amplitude is continously above a trigger amplitude for a set duration, then a DAK key is triggered.

The following settings are possible to configure:

  • Minimum amplitude (dBA): Choose the trigger amplitude.
  • Minimum duration of audio (ms): Choose for how long the sampled amplitude must be above the "Trigger ampltiude" before triggering the DAK key.
  • DAK key to activate: Choose which DAK key to trigger.
  • Minimum time before reactivation (ms): Choose how long to wait before enabling VAD after triggering the DAK key.
  • Report DAK key off after (ms): With this parameter it is possible to delay sending DAK key off for some time.
  • VAD status: Choose whether to enable to disable VAD.
