# AudioHardwareObject

The audio HAL provides an abstraction through which applications can access audio hardware. To do this, the HAL provides a small set of audio objects that provide access to the various pieces of the system. Audio objects all have a set of properties that describe and manipulate their state. AudioHardwareObject is a base class for all other audio objects. As such, all classes inherit this set of properties.

## Declaration

```swift
class AudioHardwareObject
```
