-Overview of PortAudio

- -
PortAudio is a library that provides streaming audio input -and output. 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. -

Here are the steps to writing a PortAudio application: -

    -
  1. -Write a callback function that will be called by PortAudio when audio processing -is needed.
    2. - -
  2. -Initialize the PA library and open a stream for audio I/O.
    3. - -
  3. -Start the stream. Your callback function will be now be called repeatedly -by PA in the background.
    4. - -
  4. -In your callback you can read audio data from the inputBuffer and/or write -data to the outputBuffer.
    5. - -
  5. -Stop the stream by returning 1 from your callback, or by calling a stop -function.
    6. - -
  6. -Close the stream and terminate the library.
    7. -
-
- -
There is also another interface -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. -

Let's continue by building a simple application that will play a sawtooth -wave. -
