Advanced Audio
Advanced audio settings can improve audio quality by speech filtering and echo and noise
cancellation.
When enabled, the speech filter reduces noise by filtering out all frequencies below 100Hz
and above 3500 Hz. This improves sound quality if a person is close to the microphone
when talking and reduces background noises.
Enable echo cancellation to reduce acoustic echoing that can be caused by audio coming
from a speaker and captured by a microphone.
Noise cancelling is a way of reducing the background noise if the microphone is set up in
a noisy environment and you are only interested in hearing a person who is talking close
to the microphone. The noise canceller attenuation produces maximum noise reduction
when set to 18dB of attenuation. Optimize the sound quality by listening to the sound and
adjusting the attenuation level as required.
When satisfied with the settings, click Save. Click Reset to revert to the old settings.
