Feature preview

The Feature preview allows you to test various functions that are currently under development before the official release.


The Accessibility setting enables you to adjust the alfaview interface, activate the screen reader, or learn about available keyboard shortcuts. For a detailed description of all functions and settings, please refer to the Accessibility page.

Dark theme

The Dark theme setting allows you to switch between a light and dark display of alfaview. Simply click on the slider to toggle between the two options.

Echo cancellation

To prevent audio feedback, we recommend activating the Echo cancellation setting when using a separate microphone and speaker. This will prevent the microphone from picking up the audio transmission from the loudspeaker and transmitting it again.

Note that Echo cancellation is automatically disabled when using a headset.

Noise cancellation

Noise cancellation filters out unwanted background noise from the microphone transmission and thus improves the audio quality.

Microphone optimization

Echo cancellation, Noice cancellation and Microphone optimization

We recommend using automatic noise cancellation. If you want to adjust the noise cancellation manually, you can use the Microphone optimization. Here you can set the input level at which the microphone transmits your voice.

  • Deactivate the Noise cancellation.
  • Click on the menu item Microphone optimization.
  • Speak into your microphone and adjust the sensitivity using the slider. Ensure that the indicator bar turns blue and moves to the right beyond the slider when speaking.
  • When you are not speaking, the indicator bar should be orange or invisible, indicating that your sound is not being transmitted.

To ensure the best transmission quality, we recommend to maintain a consistent distance from the microphone. Additionally, you can use the Optimization wizard. This feature automatically adjusts the level based on a short voice sample.

Blur surroundings

Settings – Blur surroundings

This setting enables or disables background blurring and adjusts its strength. If blurring is enabled, you can set the Focus area using an additional slider.

The Pixelate option is only available when experimental functions are enabled.
