Java methods that call PortAudio via JNI. This is a portable audio I/O library that can be used as an alternative to JavaSound.
Please see the PortAudio documentation for a full explanation.
http://portaudio.com/docs/ http://portaudio.com/docs/v19-doxydocs/portaudio_8h.html
This Java binding does not support audio callbacks because an audio callback should never block. Calling into a Java virtual machine might block for garbage collection or synchronization. So only the blocking read/write mode is supported.

static native int com.portaudio.PortAudio.getVersion |
( |
| ) |
|
|
static |
- Returns
- the release number of the currently running PortAudio build, eg 1900.
static native String com.portaudio.PortAudio.getVersionText |

int |
apiDeviceIndex |
|
) |
| |
|
static |
- Parameters
-
hostApiIndex | A valid host API index ranging from 0 to (getHostApiCount()-1) |
apiDeviceIndex | A valid per-host device index in the range 0 to (getHostApiInfo(hostApi).deviceCount-1) |
- Returns
- standard PortAudio device index
static native int com.portaudio.PortAudio.hostApiTypeIdToHostApiIndex |
( |
int |
hostApiType | ) |
|
|
static |
- Parameters
-
hostApiType | A unique host API identifier, for example HOST_API_TYPE_COREAUDIO. |
- Returns
- a runtime host API index
static native void com.portaudio.PortAudio.initialize |
( |
| ) |
|
|
static |
Library initialization function - call this before using PortAudio. This function initializes internal data structures and prepares underlying host APIs for use. With the exception of getVersion(), getVersionText(), and getErrorText(), this function MUST be called before using any other PortAudio API functions.
- Parameters
-
inputStreamParameters | input description, may be null |
outputStreamParameters | output description, may be null |
sampleRate | typically 44100 or 48000, or maybe 22050, 16000, 8000, 96000 |
- Returns
- 0 if supported or a negative error
- Parameters
-
inputStreamParameters | input description, may be null |
outputStreamParameters | output description, may be null |
sampleRate | typically 44100 or 48000, or maybe 22050, 16000, 8000, 96000 |

static native void com.portaudio.PortAudio.terminate |
( |
| ) |
|
|
static |
Library termination function - call this when finished using PortAudio. This function deallocates all resources allocated by PortAudio since it was initialized by a call to initialize(). In cases where Pa_Initialise() has been called multiple times, each call must be matched with a corresponding call to terminate(). The final matching call to terminate() will automatically close any PortAudio streams that are still open.
