  - isCreated
```
public static boolean isCreated()
```
    Returns:
    
    true if AL has been created
  - create
```
public static void create(String deviceArguments,
                          int contextFrequency,
                          int contextRefresh,
                          boolean contextSynchronized)
                   throws LWJGLException
```
    Creates an OpenAL instance. Using this constructor will cause OpenAL to open the device using supplied device argument, and create a context using the context values supplied.
    
    Parameters:
    
    deviceArguments - Arguments supplied to native device
    
    contextFrequency - Frequency for mixing output buffer, in units of Hz (Common values include 11025, 22050, and 44100).
    
    contextRefresh - Refresh intervalls, in units of Hz.
    
    contextSynchronized - Flag, indicating a synchronous context.*
    
    Throws:
    
    LWJGLException
  - create
```
public static void create(String deviceArguments,
                          int contextFrequency,
                          int contextRefresh,
                          boolean contextSynchronized,
                          boolean openDevice)
                   throws LWJGLException
```
    Parameters:
    
    openDevice - Whether to automatically open the device
    
    Throws:
    
    LWJGLException

    create(String, int, int, boolean)
  - create
```
public static void create()
                   throws LWJGLException
```
    Creates an OpenAL instance. The empty create will cause OpenAL to open the default device, and create a context using default values. This method used to use default values that the OpenAL implementation chose but this produces unexpected results on some systems; so now it defaults to 44100Hz mixing @ 60Hz refresh.
    
    Throws:
    
    LWJGLException
  - destroy
```
public static void destroy()
```
    Exit cleanly by calling destroy.
  - getContext
```
public static ALCcontext getContext()
```
    Returns:
    
    handle to the default AL context.
  - getDevice
```
public static ALCdevice getDevice()
```
    Returns:
    
    handle to the default AL device.
