Audio capture and digitizing devices are configured via the System Setup dialog box.
Audio capture and digitizing devices are configured by setting the audio signal sample rate and sound volume.
The sample rate is the same for all audio signals, processed by a common device; it can’t be individually set for every audio signal.
The number of hertz depends on the selected rate on the settings panel of the Audio card object and playback of audio from IP device is performed using any codec selected on the camera and supported by this device in the Drivers Pack. See Requirements for audio input units for the list of supported codecs.
Volume is adjusted after the audio signal has been digitized by the audio capture device. With Axxon PSIM™ software you can restrict volume to a certain value or switch on the automatic gain control (AGC). This levels out the sound volume across the range to a constant level.
