This article describes the two main audio modes used for Exigo devices, Voice and HD Audio.

The Audio Device Mode in used for the analog audio input.
Each device can be configured for either Voice or HD Audio.
When configure a new system it is possible to choose the preferred Audio Device Mode for all devices:

Audio Device Mode


By default the Audio Device Mode is set to HD Audio.
This may be changed later in System -> Default Configuration.

It is also possible to set the mode for each individual device:

Audio Device Mode


HD Audio

In this mode Exigo is sending pure Linear PCM 16-bit 48 KHz sampled audio over RTP.
This mode is used when higher audio quality (high audio bandwidth) is needed.
For background music this mode is also recommended.
The network bandwidth for HD Audio is approximately 800 kbit/s (per stream).

Voice

In this mode the device uses the G.722 codec.
G.722 is also used for all pre-recorded messaging, alarm, live speech etc.
Voice mode can be used when audio quality is not critical and bandwidth should be limited.


Availability

This function is available on Exigo 1.3.3 and newer.
