AXIS 211M - Audio Settings
19
Advanced Audio
Advanced audio settings can improve audio quality by speech filtering, echo cancellation or setting the noise
canceller threshold value or attenuation.
When enabled the speech filter reduces noise by filtering out all the frequencies below 100HZ and above 3500
Hz. This improves the sound quality if a person is close to the microphone when talking and will reduce
background noises.
Enable echo cancellation to reduce acoustic echoing that can be caused by audio coming from a speaker being
captured by a microphone.
Noise canceling is a way of reducing the background noise if the microphone, for example, 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.
