Advanced Audio Settings
The Audio Quality Settings allow you to fine-tune the internal or external microphone
connected to the AXIS 210A/211A 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 - If audio from the speaker is captured by the microphone, this
will produce an echo. Enable this option to reduce acoustic echoing.
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 210A/211A when
someone is speaking close to the microphone.
