Audio Device Control
The VAPIX® Audio Device Control API contains the information required to configure and control your audio devices in various ways, including:
- Retrieving a list of available audio capabilities for the device as well as the external audio devices that can be plugged into it.
- Retrieving a list of of both configurable and current audio settings on your device, as well as any compatible external audio device.
- Setting the gain value for selected inputs and outputs.
- Setting the type value for selected input and outputs.
- Muting selected inputs and outputs.
The API is based around audio devices with inputs and outputs. For example, a speaker will always have at least one device with one output that is always available and cannot be disconnected.

Overview
The API uses audiodevicecontrol.cgi as its communications interface and supports the following methods:
| Method | Description |
|---|---|
getDevicesCapabilities | Retrieves a list of all audio capabilities on your device. |
getDevicesSettings | Retrieves a list of the current audio parameters. |
setDevicesSettings | Sets the audio parameters. |
getHazardousSettings | Retrieves a list of hazardous settings. |
getSupportedVersions | Retrieves a list of supported API versions. |

Common examples
Retrieve audio capabilities
Use this example to retrieve a list containing all available audio capabilities for your device. The list will include the number of accepted gain values as well as accepted power types that can be applied to the audio device.
- Start with the following request:
http://<servername>/axis-cgi/audiodevicecontrol.cgi
JSON input parameters
{
"apiVersion": "1.0",
"context": "abc",
"method": "getDevicesCapabilities"
}
- Parse the JSON response. A successful response will return a list containing all available devices along with their capabilities.
