Advanced Audio Settings - Axis 213 PTZ User Manual

Advanced Audio Settings

The Advanced Audio settings allows you to tune the external microphone connected
to the AXIS 213's connection module to suit your environment.
Enable speech filter improves the sound quality when the microphone is placed close
to the person talking and can also help reduce background noise. The filter cuts the
lowest and the highest frequencies. The bypass frequency range is approximately
250Hz to 3700Hz (measured at -10dB cut-off break points).
Enable echo cancellation reduces acoustic echoing if sound from the speaker is
captured by the microphone.
Noise canceling is a way of reducing the background noise when there is no useful
audio present. A typical application could be that the camera is set up in a noisy
environment, and you are only interested in hearing the sound from the AXIS 213
when someone is speaking close to the microphone. There are two adjustable
parameters available to optimize this function:
• Noise canceller threshold value
• Noise canceller attenuation
When the incoming sound is louder than the threshold, it will pass without any
changes. When lower than the threshold, the incoming sound will be reduced by a
certain attenuation factor. The threshold level should be set higher than the
background noise, but lower than the useful audio.
