AXIS 211M - Audio Settings
Depending on the selected encoding, set the desired Bit rate (audio quality). The settings depend on the available bandwidth and the required audio quality, i.e. a high bit rate setting requires more bandwidth.
The AXIS 211M can be set to trigger an event if the incoming sound level rises above, falls below or passes the set value. The Alarm level is set between
Audio Output
If the sound from the speaker is too low or high, adjust the output gain for the active speaker attached to the AXIS 211M. When satisfied with the settings, click Save, or click Reset to revert to the previously saved settings.
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.
