EXTCapture (LWJGL 3.2.4 SNAPSHOT

java.lang.Object
- org.lwjgl.openal.EXTCapture

```
public class EXTCapture
extends java.lang.Object
```
Native bindings to the ALC_EXT_CAPTURE extension.
An OpenAL 1.1 implementation will always support the ALC_EXT_CAPTURE extension. This allows an application written to the OpenAL 1.0 specification to access the capture abilities.

public static long alcCaptureOpenDevice(@Nullable
                                        java.nio.ByteBuffer deviceName,
                                        int frequency,

                                        int samples)
```
    Allows the application to connect to a capture device.
    The deviceName argument is a null terminated string that requests a certain device or device configuration. If NULL is specified, the implementation will provide an implementation specific default.
    
    Parameters:
    
    deviceName - the device or device configuration
    
    frequency - the audio frequency
    
    format - the audio format
    
    samples - the number of sample frames to buffer in the AL
  - alcCaptureOpenDevice
```
public static long alcCaptureOpenDevice(@Nullable
                                        java.lang.CharSequence deviceName,
                                        int frequency,
                                        int format,
                                        int samples)
```
    Allows the application to connect to a capture device.
    The deviceName argument is a null terminated string that requests a certain device or device configuration. If NULL is specified, the implementation will provide an implementation specific default.
    
    Parameters:
    
    deviceName - the device or device configuration
    
    frequency - the audio frequency
    
    format - the audio format
    
    samples - the number of sample frames to buffer in the AL
  - alcCaptureCloseDevice
```
public static boolean alcCaptureCloseDevice(long device)
```
    Allows the application to disconnect from a capture device.
    
    Parameters:
    
    device - the capture device to close
  - alcCaptureStart
```
public static void alcCaptureStart(long device)
```
    Starts recording audio on the specific capture device.
    Once started, the device will record audio to an internal ring buffer, the size of which was specified when opening the device. The application may query the capture device to discover how much data is currently available via the alcGetInteger with the ALC_CAPTURE_SAMPLES token. This will report the number of sample frames currently available.
    
    Parameters:
    
    device - the capture device
  - alcCaptureStop
```
public static void alcCaptureStop(long device)
```
    Halts audio capturing without closing the capture device.
    The implementation is encouraged to optimize for this case. The amount of audio samples available after restarting a stopped capture device is reset to zero. The application does not need to stop the capture device to read from it.
    
    Parameters:
    
    device - the capture device
  - nalcCaptureSamples
```
public static void nalcCaptureSamples(long device,
                                      long buffer,

```
    Obtains captured audio samples from the AL.
    The implementation may defer conversion and resampling until this point. Requesting more sample frames than are currently available is an error.
    
    Parameters:
    
    device - the capture device
    
    buffer - the buffer that will receive the samples. It must be big enough to contain at least samples sample frames.
    
    samples - the number of sample frames to obtain
