It is a cross-platform API (Application Programming Interface) -that works on Windows, Macintosh, Unix running OSS, SGI, BeOS, and perhaps -other platforms by the time you read this. This means that you can write -a simple 'C' program to process or generate an audio signal, and that program -can run on several different types of computer just by recompiling the -source code. -<p>Here are the steps to writing a PortAudio application: -<ol> -<li> -Write a callback function that will be called by PortAudio when audio processing -is needed.</li> - -<li> -Initialize the PA library and open a stream for audio I/O.</li> - -<li> -Start the stream. Your callback function will be now be called repeatedly -by PA in the background.</li> - -<li> -In your callback you can read audio data from the inputBuffer and/or write -data to the outputBuffer.</li> - -<li> -Stop the stream by returning 1 from your callback, or by calling a stop -function.</li> - -<li> -Close the stream and terminate the library.</li> -</ol> -</blockquote> - -<blockquote>There is also <a href="pa_tut_rw.html">another interface</a> -provided that allows you to generate audio in the foreground. You then -simply write data to the stream and the tool will not return until it is -ready to accept more data. This interface is simpler to use but is usually -not preferred for large applications because it requires that you launch -a thread to perform the synthesis. Launching a thread may be difficult -on non-multi-tasking systems such as the Macintosh prior to MacOS X. -<p>Let's continue by building a simple application that will play a sawtooth -wave. -<p>Please select the page for the specific implementation you would like -to use: -<ul> -<li> -<a href="pa_tut_pc.html">Windows (WMME or DirectSound)</a></li> - -<li> -<a href="pa_tut_mac.html">Macintosh SoundManager for OS 7,8,9</a></li> - -<li> -<a href="pa_tut_mac_osx.html">Macintosh CoreAudio for OS X</a></li> - -<li> -<a href="pa_tut_asio.html">ASIO on Windows or Macintosh</a></li> - -<li> -<a href="pa_tut_oss.html">Unix OSS</a></li> -</ul> -or continue with the <a href="pa_tut_callback.html">next page of the programming -tutorial</a>.</blockquote> -<font size=+2><a href="http://www.portaudio.com/">home</a> | -<a href="pa_tutorial.html">contents</a> -| <a href="pa_tutorial.html">previous</a></font> -</body> -</html> |
