The DICENTIS system uses its Dynamic Channel Allocation (DCA) technology to sense all
microphones continuously in order to:
– Quickly open the microphones if audio is detected to prevent missing syllables.
– Reduce the number of open microphones to prevent noise for optimum speech
intelligibility.
The DCA algorithm keeps the microphone open for 2 seconds for optimum performance.
Due to its continuous sensing of the audio, it can happen that one microphone is shown in the
speaker list even though nobody is speaking.
– Once you have checked the Show active microphone box, you can:
- Use the Attack time slider to set the minimal audio duration. The minimal audio
duration prevents short audio spikes, like coughing, from placing the participant in
the speaker list. The attack time sets how long the audio needs to be before it is
regarded as speech. The default recommended is 2000 ms. The minimum is 0 ms.
The maximum is 10 000 ms.
- Use the
Release time slider to set the duration the microphone stays on after the
audio level becomes too low. The default is 500 ms. The minimum is 0 ms. The
maximum is 10 000 ms.
- Check the
Show active by red mic LED checkbox to light up the red microphone
LED when the participant is in the speaker list.
- Configure the number of speakers displayed in the speaker list in
Max active
microphones . One is the recommended value.
