+\r
+<i>Note: this page has not been reviewed, and may contain errors.</i>\r
+\r
+@section java_draft DRAFT - IN PROGRESS\r
+\r
+9/1/12 JPortAudio is very new and should be considered an "alpha" release.\r
+The building of JPortAudio will eventually be integrated into the Makefile as an optional build.\r
+\r
+Currently JPortAudio is only supported for Windows. Please contact us if you want to help with porting to Mac or Linux.\r
+\r
+@section java_comp_windows Building JPortAudio on Windows\r
+\r
+Build the Java code using the Eclipse project in "jportaudio". Export as "jportaudio.jar".\r
+\r
+If you modify the JNI API then you will need to regenerate the JNI .h files using:\r
+\r
+@code\r
+cd bindings/java/scripts\r
+make_header.bat\r
+@endcode\r
+\r
+Build the JNI DLL using the Visual Studio 2010 solution in "java/c/build/vs2010/PortAudioJNI".\r
+\r
+@section java_use_windows Using JPortAudio on Windows\r
+\r
+Put the "jportaudio.jar" in the classpath for your application.\r
+Place the following libraries where they can be found, typically in the same folder as your application.\r
+\r
+- portaudio_x86.dll\r
+- portaudio_x64.dll\r
+- jportaudio_x86.dll\r

@section overview Overview\r
\r
-PortAudio is a cross-platform, open-source C language library for real-time audio input and output. The library provides functions that allow your software to acquire and output real-time audio streams from your computer's hardware audio interfaces. It is designed to simplify writing cross-platform audio applications, and also to simplify the development of audio software in general by hiding the complexities of dealing directly with each native audio API. PortAudio is used to implement sound recording, editing and mixing applications, software synthesizers, effects processors, music players, internet telephony applications, software defined radios and more. Supported platforms include MS Windows, Mac OS X and Linux. Third-party language bindings make it possible to call PortAudio from other programming languages including C++, C#, Python, PureBasic, FreePascal and Lazarus.\r

+Below are the steps to writing a PortAudio application using the callback technique:\r
\r
- Write a callback function that will be called by PortAudio when audio processing is needed.\r
- Initialize the PA library and open a stream for audio I/O.\r
\r
In this tutorial, we'll show how to use the callback architecture to play a sawtooth wave. Much of the tutorial is taken from the file paex_saw.c, which is part of the PortAudio distribution. When you're done with this tutorial, you'll be armed with the basic knowledge you need to write an audio program. If you need more sample code, look in the "examples" and "test" directory of the PortAudio distribution. Another great source of info is the portaudio.h Doxygen page, which documents the entire V19 API. Also see the page for <a href="http://www.assembla.com/spaces/portaudio/wiki/Tips">tips on programming PortAudio</a> on the PortAudio wiki.\r
