-<h2>
-<a NAME="what"></a>What is Latency?</h2>
-Latency is basically longest time that you have to wait before you obtain
-a desired result. For digital audio output it is the time between making
-a sound in software and finally hearing it.
-<p>Consider the example of pressing a key on the ASCII keyboard to play
-a note. There are several stages in this process which each contribute
-their own latency. First the operating system must respond to the keypress.
-Then the audio signal generated must work its way through the PortAudio
-buffers. Then it must work its way through the audio card hardware. Then
-it must go through the audio amplifier which is very quick and then travel
-through the air. Sound travels at abous one foot per millisecond through
-air so placing speakers across the room can add 5-20 msec of delay.
-<p>The reverse process occurs when recording or responding to audio input.
-If you are processing audio, for example if you implement a software guitar
-fuzz box, then you have both the audio input and audio output latencies
-added together.
-<p>The audio buffers are used to prevent glitches in the audio stream.
-The user software writes audio into the output buffers. That audio is read
-by the low level audio driver or by DMA and sent to the DAC. If the computer
-gets busy doing something like reading the disk or redrawing the screen,
-then it may not have time to fill the audio buffer. The audio hardware
-then runs out of audio data, which causes a glitch. By using a large enough
-buffer we can ensure that there is always enough audio data for the audio
-hardware to play. But if the buffer is too large then the latency is high
-and the system feels sluggish. If you play notes on the keyboard then the
-"instrument" will feel unresponsive. So you want the buffers to be as small
-as possible without glitching.
-<h2>
-<a NAME="portaudio"></a>PortAudio and Latency</h2>
-The only delay that PortAudio can control is the total length of its buffers.
-The Pa_OpenStream() call takes two parameters: numBuffers and framesPerBuffer.
-The latency is also affected by the sample rate which we will call framesPerSecond.
-A frame is a set of samples that occur simultaneously. For a stereo stream,
-a frame is two samples.
-<p>The latency in milliseconds due to this buffering&nbsp; is:
-<blockquote><tt>latency_msec = 1000 * numBuffers * framesPerBuffer / framesPerSecond</tt></blockquote>
-This is not the total latency, as we have seen, but it is the part we can
-control.
-<p>If you call Pa_OpenStream() with numBuffers equal to zero, then PortAudio
-will select a conservative number that will prevent audio glitches. If
-you still get glitches, then you can pass a larger value for numBuffers
-until the glitching stops. if you try to pass a numBuffers value that is
-too small, then PortAudio will use its own idea of the minimum value.
-<p>PortAudio decides on the minimum number of buffers in a conservative
-way based on the frameRate, operating system and other variables. You can
-query the value that PortAudio will use by calling:
-<blockquote><tt>int Pa_GetMinNumBuffers( int framesPerBuffer, double sampleRate
-);</tt></blockquote>
-On some systems you can override the PortAudio minimum if you know your
-system can handle a lower value. You do this by setting an environment
-variable called PA_MIN_LATENCY_MSEC which is read by PortAudio when it
-starts up. This is supported on the PortAudio implementations for Windows
-MME, Windows DirectSound, and Unix OSS.
-<h2>
-<a NAME="macintosh"></a>Macintosh</h2>
-The best thing you can do to improve latency on Mac OS 8 and 9 is to turn
-off Virtual Memory. PortAudio V18 will detect that Virtual Memory is turned
-off and use a very low latency.
-<p>For Mac OS X the latency is very low because Apple Core Audio is so
-well written. You can set the PA_MIN_LATENCY_MSEC variable using:
-<blockquote><tt>setenv PA_MIN_LATENCY_MSEC 4</tt></blockquote>
-
-<h2>
-<a NAME="unix"></a>Unix</h2>
-PortAudio under Unix currently uses a backgroud thread that reads and writes
-to OSS. This gives you decent but not great latency. But if you raise the
-priority of the background thread to a very priority then you can get under
-10 milliseconds latency. In order to raise your priority you must run the
-PortAudio program as root! You must also set PA_MIN_LATENCY_MSEC using
-the appropriate command for your shell.
-<h2>
-<a NAME="windows"></a>Windows</h2>
-Latency under Windows is a complex issue because of all the alternative
-operating system versions and device drivers. I have seen latency range
-from 8 milliseconds to 400 milliseconds. The worst case is when using Windows
-NT. Windows 98 is a little better, and Windows XP can be quite good if
-properly tuned.
-<p>The underlying audio API also makes a lot of difference. If the audio
-device has its own DirectSound driver then DirectSound can often provide
-better latency than WMME. But if a real DirectSound driver is not available
-for your device then it is emulated using WMME and the latency can be very
-high. That's where I saw the 400 millisecond latency. The ASIO implementation
-is generally very good and will give the lowest latency if available.
-<p>You can set the PA_MIN_LATENCY_MSEC variable to 50, for example, by
-entering in MS-DOS:
-<blockquote><tt>set PA_MIN_LATENCY_MSEC=50</tt></blockquote>
-If you enter this in a DOS window then you must run the PortAudio program
-from that same window for the variable to have an effect. You can add that
-line to your C:\AUTOEXEC.BAT file and reboot if you want it to affect any
-PortAudio based program.
-<p>For Windows XP, you can set environment variables as follows:
-<ol>
-<li>
-Select "Control Panel" from the "Start Menu".</li>
-
-<li>
-Launch the "System" Control Panel</li>
-
-<li>
-Click on the "Advanced" tab.</li>
-
-<li>
-Click on the "Environment Variables" button.</li>
-
-<li>
-Click "New" button under&nbsp; User Variables.</li>
-
-<li>
-Enter PA_MIN_LATENCY_MSEC for the name and some optimistic number for the
-value.</li>
-
-<li>
-Click OK, OK, OK.</li>
-</ol>
-
-<h3>
-Improving Latency on Windows</h3>
-There are several steps you can take to improve latency under windows.
-<ol>
-<li>
-Avoid reading or writng to disk when doing audio.</li>
-
-<li>
-Turn off all automated background tasks such as email clients, virus scanners,
-backup programs, FTP servers, web servers, etc. when doing audio.</li>
-
-<li>
-Disconnect from the network to prevent network traffic from interrupting
-your CPU.</li>
-</ol>
-<b>Important: </b>Windows XP users can also tune the OS to favor background
-tasks, such as audio, over foreground tasks, such as word processing. I
-lowered my latency from 40 to 10 milliseconds using this simple technique.
-<ol>
-<li>
-Select "Control Panel" from the "Start Menu".</li>
-
-<li>
-Launch the "System" Control Panel</li>
-
-<li>
-Click on the "Advanced" tab.</li>
-
-<li>
-Click on the "Settings" button in the Performance area.</li>
-
-<li>
-Click on the "Advanced" tab.</li>
-
-<li>
-Select "Background services" in the Processor Scheduling area.</li>
-
-<li>
-Click OK, OK.</li>
-</ol>
-Please let us know if you have others sugestions for lowering latency.

-<p>This document describes how to implement the PortAudio API on a new
-computer platform. Implementing PortAudio on a new platform, makes it possible
-to port many existing audio applications to that platform.
-<p>By Phil Burk
-<br>Copyright 2000 Phil Burk and Ross Bencina
-<p>Note that the license says: <b>"Any person wishing to distribute modifications
-to the Software is requested to send the modifications to the original
-developer so that they can be incorporated into the canonical version."</b>.
-So when you have finished a new implementation, please send it back to
-us at&nbsp; "<a href="http://www.portaudio.com">http://www.portaudio.com</a>"
-so that we can make it available for other users. Thank you!
-<h2>
-Download the Latest PortAudio Implementation</h2>
-Always start with the latest implementation available at "<a href="http://www.portaudio.com">http://www.portaudio.com</a>".
-Look for the nightly snapshot under the CVS section.
-<h2>
-Select an Existing Implementation as a Basis</h2>
-The fastest way to get started is to take an existing implementation and
-translate it for your new platform. Choose an implementation whose architecture
-is as close as possible to your target.
-<ul>
-<li>
-DirectSound Implementation - pa_win_ds - Uses a timer callback for the
-background "thread". Polls a circular buffer and writes blocks of data
-to keep it full.</li>
-
-<li>
-Windows MME - pa_win_wmme - Spawns an actual Win32 thread. Writes blocks
-of data to the HW device and waits for events that signal buffer completion.</li>
-
-<li>
-Linux OSS - pa_linux - Spawns a real thread that writes to the "/dev/dsp"
-stream using blocking I/O calls.</li>
-</ul>
-When you write a new implementation, you will be using some code that is
-in common with all implementations. This code is in the folder "pa_common".
-It provides various functions such as parameter checking, error code to
-text conversion, sample format conversion, clipping and dithering, etc.
-<p>The code that you write will go into a separate folder called "pa_{os}_{api}".
-For example, code specific to the DirectSound interface for Windows goes
-in "pa_win_ds".
-<h2>
-Read Docs and Code</h2>
-Famialiarize yourself with the system by reading the documentation provided.
-here is a suggested order:
-<ol>
-<li>
-User Programming <a href="pa_tutorial.html">Tutorial</a></li>
-
-<li>
-Header file "pa_common/portaudio.h" which defines API.</li>
-
-<li>
-Header file "pa_common/pa_host.h" for host dependant code. This definces
-the routine you will need to provide.</li>
-
-<li>
-Shared code in "pa_common/pa_lib.c".</li>
-
-<li>
-Docs on Implementation of <a href="pa_impl_startstop.html">Start/Stop</a>
-code.</li>
-</ol>
-
-<h2>
-Implement&nbsp; Output to Default Device</h2>
-Now we are ready to crank some code. For instant gratification, let's try
-to play a sine wave.
-<ol>
-<li>
-Link the test program "pa_tests/patest_sine.c" with the file "pa_lib.c"
-and the implementation specific file you are creating.</li>
-
-<li>
-For now, just stub out the device query code and the audio input code.</li>
-
-<li>
-Modify PaHost_OpenStream() to open your default target device and get everything
-setup.</li>
-
-<li>
-Modify PaHost_StartOutput() to start playing audio.</li>
-
-<li>
-Modify PaHost_StopOutput() to stop audio.</li>
-
-<li>
-Modify PaHost_CloseStream() to clean up. Free all memory that you allocated
-in PaHost_OpenStream().</li>
-
-<li>
-Keep cranking until you can play a sine wave using "patest_sine.c".</li>
-
-<li>
-Once that works, try "patest_pink.c", "patest_clip.c", "patest_sine8.c".</li>
-
-<li>
-To test your Open and Close code, try "patest_many.c".</li>
-
-<li>
-Now test to make sure that the three modes of stopping are properly supported
-by running "patest_stop.c".</li>
-
-<li>
-Test your implementation of time stamping with "patest_sync.c".</li>
-</ol>
-
-<h2>
-Implement Device Queries</h2>
-Now that output is working, lets implement the code for querying what devices
-are available to the user. Run "pa_tests/pa_devs.c". It should print all
-of the devices available and their characteristics.
-<h2>
-Implement Input</h2>
-Implement audio input and test it with:
-<ol>
-<li>
-patest_record.c - record in half duplex, play back as recorded.</li>
-
-<li>
-patest_wire.c - full duplex, copies input to output. Note that some HW
-may not support full duplex.</li>
-
-<li>
-patest_fuzz.c - plug in your guitar and get a feel for why latency is an
-important issue in computer music.</li>
-
-<li>
-paqa_devs.c - try to open every device and use it with every possible format</li>
-</ol>
-
-<h2>
-Debugging Tools</h2>
-You generally cannot use printf() calls to debug real-time processes because
-they disturb the timing. Also calling printf() from your background thread
-or interrupt could crash the machine. So PA includes a tool for capturing
-events and storing the information while it is running. It then prints
-the events when Pa_Terminate() is called.
-<ol>
-<li>
-To enable trace mode, change TRACE_REALTIME_EVENTS in "pa_common/pa_trace.h"
-from a (0) to a (1).</li>
-
-<li>
-Link with "pa_common/pa_trace.c".</li>
-
-<li>
-Add trace messages to your code by calling:</li>
-
-<br><tt>&nbsp;&nbsp; void AddTraceMessage( char *msg, int data );</tt>
-<br><tt>for example</tt>
-<br><tt>&nbsp;&nbsp; AddTraceMessage("Pa_TimeSlice: past_NumCallbacks ",
-past->past_NumCallbacks );</tt>
-<li>
-Run your program. You will get a dump of events at the end.</li>
-
-<li>
-You can leave the trace messages in your code. They will turn to NOOPs
-when you change TRACE_REALTIME_EVENTS back to (0).</li>
-</ol>
-
-<h2>
-Delivery</h2>
-Please send your new code along with notes on the implementation back to
-us at "<a href="http://www.portaudio.com">http://www.portaudio.com</a>".
-We will review the implementation and post it with your name. If you had
-to make any modifications to the code in "pa_common" or "pa_tests" <b>please</b>
-send us those modifications and your notes. We will try to merge your changes
-so that the "pa_common" code works with <b>all</b> implementations.
-<p>If you have suggestions for how to make future implementations easier,
-please let us know.
-<br>THANKS!

-<h2>
-Starting and Stopping Streams</h2>
-PortAudio is generally executed in two "threads". The foreground thread
-is the application thread. The background "thread" may be implemented as
-an actual thread, an interrupt handler, or a callback from a timer thread.
-<p>There are three ways that PortAudio can stop a stream. In each case
-we look at the sequence of events and the messages sent between the two
-threads. The following variables are contained in the internalPortAudioStream.
-<blockquote><tt>int&nbsp;&nbsp; past_IsActive;&nbsp;&nbsp;&nbsp;&nbsp;
-/* Background is still playing. */</tt>
-<br><tt>int&nbsp;&nbsp; past_StopSoon;&nbsp;&nbsp;&nbsp;&nbsp; /* Stop
-when last buffer done. */</tt>
-<br><tt>int&nbsp;&nbsp; past_StopNow;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /*
-Stop IMMEDIATELY. */</tt></blockquote>
-
-<h3>
-Pa_AbortStream()</h3>
-This function causes the background thread to terminate as soon as possible
-and audio I/O to stop abruptly.

-User callback returns one.</h3>
-If the user callback returns one then the user callback function will no

-to the output buffer has been played. Then the audio I/O is stopped, the
-background thread terminates, and the stream becomes inactive.

-<h2>
-Compiling for ASIO (Windows or Macintosh)</h2>
-
-<blockquote>ASIO is a low latency audio API from Steinberg. To compile
-an ASIO application, you must first <a href="http://www.steinberg.net/developers/ASIO2SDKAbout.phtml">download
-the ASIO SDK</a> from Steinberg. You also need to obtain ASIO drivers for
-your audio device.
-<p>Note: I am using '/' as a file separator below. On Macintosh replace
-'/' with ':'. On Windows, replace '/' with '\'.
-<p>&nbsp;To use ASIO with the PortAudio library add the following source
-files to your project:
-<blockquote>
-<pre>pa_asio/pa_asio.cpp</pre>
-</blockquote>
-and also these files from the ASIO SDK:
-<blockquote>
-<pre>common/asio.cpp
-host/asiodrivers.cpp
-host/asiolist.cpp</pre>
-</blockquote>
-and add these directories to the path for include files
-<blockquote>
-<pre>asiosdk2/host/pc&nbsp;&nbsp; (for Windows)
-asiosdk2/common
-asiosdk2/host</pre>
-</blockquote>
-You may try compiling the "pa_tests/patest_saw.c" file first because it
-is the simplest.</blockquote>

-<h2>
-Writing a Callback Function</h2>
-
-<blockquote>To write a program using PortAudio, you must include the "portaudio.h"
-include file. You may wish to read "<a href="portaudio_h.txt">portaudio.h</a>"
-because it contains a complete description of the PortAudio functions and
-constants.
-<blockquote>
-<pre>#include "portaudio.h"</pre>
-</blockquote>
-The next task is to write your custom callback function. It is a function
-that is called by the PortAudio engine whenever it has captured audio data,
-or when it needs more audio data for output.
-<p>Your callback function is often called by an interrupt, or low level
-process so you should not do any complex system activities like allocating
-memory, or reading or writing files, or printf(). Just crunch numbers and
-generate audio signals. What is safe or not safe will vary from platform
-to platform. On the Macintosh, for example, you can only call "interrupt
-safe" routines. Also do not call any PortAudio functions in the callback
-except for Pa_StreamTime() and Pa_GetCPULoad().
-<p>Your callback function must return an int and accept the exact parameters
-specified in this typedef:
-<blockquote>
-<pre>typedef int (PortAudioCallback)(
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; void *inputBuffer, void *outputBuffer,
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; unsigned long framesPerBuffer,
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PaTimestamp outTime, void *userData );</pre>
-</blockquote>
-Here is an example callback function from the test file "patests/patest_saw.c".
-It calculates a simple left and right sawtooth signal and writes it to
-the output buffer. Notice that in this example, the signals are of <tt>float</tt>
-data type. The signals must be between -1.0 and +1.0. You can also use
-16 bit integers or other formats which are specified during setup. You
-can pass a pointer to your data structure through PortAudio which will
-appear as <tt>userData</tt>.
-<blockquote>
-<pre>int patestCallback(&nbsp; void *inputBuffer, void *outputBuffer,
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; unsigned long framesPerBuffer,
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; PaTimestamp outTime, void *userData )
-{
-&nbsp;&nbsp;&nbsp; unsigned int i;
-/* Cast data passed through stream to our structure type. */
-&nbsp;&nbsp;&nbsp; paTestData *data = (paTestData*)userData;
-&nbsp;&nbsp;&nbsp; float *out = (float*)outputBuffer;
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
-&nbsp;&nbsp;&nbsp; for( i=0; i&lt;framesPerBuffer; i++ )
-&nbsp;&nbsp;&nbsp; {
-&nbsp;&nbsp;&nbsp; /* Stereo channels are interleaved. */
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *out++ = data->left_phase;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /* left */
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; *out++ = data->right_phase;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /* right */
-
-&nbsp;&nbsp;&nbsp; /* Generate simple sawtooth phaser that ranges between -1.0 and 1.0. */
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; data->left_phase += 0.01f;
-&nbsp;&nbsp;&nbsp; /* When signal reaches top, drop back down. */
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if( data->left_phase >= 1.0f ) data->left_phase -= 2.0f;
-
-&nbsp;&nbsp;&nbsp; /* higher pitch so we can distinguish left and right. */
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; data->right_phase += 0.03f;&nbsp;
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if( data->right_phase >= 1.0f ) data->right_phase -= 2.0f;
-&nbsp;&nbsp;&nbsp; }

-<h2>
-Querying for Available Devices</h2>
-
-<blockquote>There are often several different audio devices available in
-a computer with different capabilities. They can differ in the sample rates
-supported, bit widths, etc. PortAudio provides a simple way to query for
-the available devices, and then pass the selected device to Pa_OpenStream().
-For an example, see the file "pa_tests/pa_devs.c".
-<p>To determine the number of devices:
-<blockquote>
-<pre>numDevices = Pa_CountDevices();</pre>
-</blockquote>
-You can then query each device in turn by calling Pa_GetDeviceInfo() with
-an index.
-<blockquote>
-<pre>for( i=0; i&lt;numDevices; i++ ) {
-&nbsp;&nbsp;&nbsp;&nbsp; pdi = Pa_GetDeviceInfo( i );</pre>
-</blockquote>
-It will return a pointer to a <tt>PaDeviceInfo</tt> structure which is
-defined as:
-<blockquote>
-<pre>typedef struct{
-&nbsp;&nbsp;&nbsp; int structVersion;&nbsp;
-&nbsp;&nbsp;&nbsp; const char *name;
-&nbsp;&nbsp;&nbsp; int maxInputChannels;
-&nbsp;&nbsp;&nbsp; int maxOutputChannels;
-/* Number of discrete rates, or -1 if range supported. */
-&nbsp;&nbsp;&nbsp; int numSampleRates;
-/* Array of supported sample rates, or {min,max} if range supported. */
-&nbsp;&nbsp;&nbsp; const double *sampleRates;
-&nbsp;&nbsp;&nbsp; PaSampleFormat nativeSampleFormat;
-}PaDeviceInfo;</pre>
-</blockquote>
-If the device supports a continuous range of sample rates, then numSampleRates
-will equal -1, and the sampleRates array will have two values, the minimum&nbsp;
-and maximum rate.
-<p>The device information is allocated by Pa_Initialize() and freed by
-Pa_Terminate() so you do not have to free() the structure returned by Pa_GetDeviceInfo().</blockquote>

-Initializing PortAudio</h2>
-
-<blockquote>Before making any other calls to PortAudio, you must call <tt>Pa_Initialize</tt>().
-This will trigger a scan of available devices which can be queried later.
-Like most PA functions, it will return a result of type <tt>paError</tt>.
-If the result is not <tt>paNoError</tt>, then an error has occurred.
-<blockquote>
-<pre>err = Pa_Initialize();
-if( err != paNoError ) goto error;</pre>

-<h2>
-Overview of PortAudio</h2>
-
-<blockquote>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.
-<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:

-<h2>
-Compiling for Windows (WMME or DirectSound)</h2>
-
-<blockquote>To compile PortAudio for Windows, you can choose between two
-options. One implementation uses the DirectSound API. The other uses the
-Windows MultiMedia Extensions API (aka WMME or WAVE).
-<p>Some advantages of using DirectSound are that DirectSound may have lower
-latency than WMME, and supports effects processing plugins. But one disadvantage
-is that DirectSound is not installed on all PCs, and is not well supported
-under Windows NT. So WMME is the best choice for most projects.
-<p>For either implementation add the following source files to your project:
-<blockquote>
-<pre><b>pa_common\pa_lib.c
-pa_common\portaudio.h
-pa_common\pa_host.h</b></pre>
-</blockquote>
-Link with the system library "<b>winmm.lib</b>". For Visual C++:
-<ol>
-<li>
-select "Settings..." from the "Project" menu,</li>
-
-<li>
-select the project name in the tree on the left,</li>
-
-<li>
-choose "All Configurations" in the popup menu above the tree,</li>
-
-<li>
-select the "Link" tab,</li>
-
-<li>
-enter "winmm.lib", without quotes, as the first item in the "Object/library
-modules:" field.</li>
-</ol>
-<b>WMME</b> - To use the WMME implementation, add the following source
-files to your project:
-<blockquote><b><tt>pa_win_wmme/pa_win_wmme.c</tt></b></blockquote>
-<b>DirectSound</b> - If you want to use the DirectSound implementation
-of PortAudio then you must have a recent copy of the free
-<a href="http://www.microsoft.com/directx/download.asp">DirectX</a>
-SDK for Developers from Microsoft installed on your computer. To compile
-an application add the following source files to your project:
-<blockquote>
-<pre><b>pa_win_ds\dsound_wrapper.c
-pa_win_ds\pa_dsound.c</b></pre>
-</blockquote>
-Link with the system library "<b>dsound.lib</b>" using the procedure described
-above for "winmm.lib".</blockquote>

-<h2>
-Starting and Stopping a Stream</h2>
-
-<blockquote>The stream will not start running until you call Pa_StartStream().
-Then it will start calling your callback function to perform the audio
-processing.
-<blockquote>
-<pre>err = Pa_StartStream( stream );
-if( err != paNoError ) goto error;</pre>
-</blockquote>
-At this point, audio is being generated. You can communicate to your callback
-routine through the data structure you passed in on the open call, or through
-global variables, or using other interprocess communication techniques.
-Please be aware that your callback function may be called at interrupt
-time when your foreground process is least expecting it. So avoid sharing
-complex data structures that are easily corrupted like double linked lists.
-<p>In many of the tests we simply sleep for a few seconds so we can hear
-the sound. This is easy to do with Pa_Sleep() which will sleep for some
-number of milliseconds. Do not rely on this function for accurate scheduling.
-it is mostly for writing examples.
-<blockquote>
-<pre>/* Sleep for several seconds. */
-Pa_Sleep(NUM_SECONDS*1000);</pre>
-</blockquote>
-When you are through, you can stop the stream from the foreground.
-<blockquote>
-<pre>err = Pa_StopStream( stream );
-if( err != paNoError ) goto error;</pre>
-</blockquote>
-You can also stop the stream by returning 1 from your custom callback function.</blockquote>

-<h2>
-Blocking Read/Write Functions</h2>
-
-<blockquote>[Note: These functions are not part of the official PortAudio
-API. They are simply built on top of PortAudio as an extra utility. Also
-note that they are under evaluation and their definition may change.]
-<p>There are two fundamentally different ways to design an audio API. One
-is to use callback functions the way we have already shown. The callback
-function operates under an interrupt or background thread This leaves the
-foreground application free to do other things while the audio just runs
-in the background. But this can sometimes be awkward.
-<p>So we have provided an alternative technique that lets a program generate
-audio in the foreground and then just write it to the audio stream as if
-it was a file. If there is not enough room in the audio buffer for more
-data, then the write function will just block until more room is available.
-This can make it very easy to write an audio example. To use this tool,
-you must add the files "pablio/pablio.c" and "pablio/ringbuffer.c" to your
-project. You must also:
-<blockquote>
-<pre>#include "pablio.h"</pre>
-</blockquote>
-Here is a short excerpt of a program that opens a stream for input and
-output. It then reads a block of samples from input, and writes them to
-output, in a loop.&nbsp; The complete example can be found in "pablio/test_rw.c".
-<blockquote>
-<pre>&nbsp;&nbsp;&nbsp; #define SAMPLES_PER_FRAME&nbsp;&nbsp;&nbsp;&nbsp; (2)
-&nbsp;&nbsp;&nbsp; #define FRAMES_PER_BLOCK&nbsp;&nbsp;&nbsp; (1024)
-&nbsp;&nbsp;&nbsp; SAMPLE&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; samples[SAMPLES_PER_FRAME * FRAMES_PER_BLOCK];
-&nbsp;&nbsp;&nbsp; PaError&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; err;
-&nbsp;&nbsp;&nbsp; PABLIO_Stream&nbsp; *aStream;
-
-/* Open simplified blocking I/O layer on top of PortAudio. */
-&nbsp;&nbsp;&nbsp; err = OpenAudioStream( &amp;rwbl, SAMPLE_RATE, paFloat32,
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (PABLIO_READ_WRITE | PABLIO_STEREO) );
-&nbsp;&nbsp;&nbsp; if( err != paNoError ) goto error;
-
-/* Process samples in the foreground. */
-&nbsp;&nbsp;&nbsp; for( i=0; i&lt;(NUM_SECONDS * SAMPLE_RATE); i++ )
-&nbsp;&nbsp;&nbsp; {
-&nbsp;&nbsp;&nbsp; /* Read one block of data into sample array from audio input. */
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ReadAudioStream( aStream, samples, FRAMES_PER_BLOCK );
-&nbsp;&nbsp;&nbsp; /*
-&nbsp;&nbsp;&nbsp; ** At this point you could process the data in samples array,
-&nbsp;&nbsp;&nbsp; ** and write the result back to the same samples array.
-&nbsp;&nbsp;&nbsp; */
-&nbsp;&nbsp;&nbsp; /* Write that same frame of data to output. */
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; WriteAudioStream( aStream, samples, FRAMES_PER_BLOCK );
-&nbsp;&nbsp;&nbsp; }
-
-&nbsp;&nbsp;&nbsp; CloseAudioStream( aStream );</pre>

-<h2>
-Terminating PortAudio</h2>
-
-<blockquote>You can start and stop a stream as many times as you like.
-But when you are done using it, you should close it by calling:</blockquote>
-
-<blockquote>
-<blockquote>
-<pre>err = Pa_CloseStream( stream );
-if( err != paNoError ) goto error;</pre>
-</blockquote>
-Then when you are done using PortAudio, you should terminate the whole
-system by calling:
-<blockquote>
-<pre>Pa_Terminate();</pre>
-</blockquote>
-That's basically it. You can now write an audio program in 'C' that will
-run on multiple platforms, for example PCs and Macintosh.
-<p>In the rest of the tutorial we will look at some additional utility
-functions, and a different way of using PortAudio that does not require

-Utility Functions</h2>
-
-<blockquote>Here are several more functions that are not critical, but
-may be handy when using PortAudio.
-<p>Pa_StreamActive() returns one when the stream in playing audio, zero
-when not playing, or a negative error number if the stream is invalid.
-The stream is active between calls to Pa_StartStream() and Pa_StopStream(),
-but may also become inactive if the callback returns a non-zero value.
-In the latter case, the stream is considered inactive after the last buffer
-has finished playing.
-<blockquote>
-<pre>PaError Pa_StreamActive( PortAudioStream *stream );</pre>
-</blockquote>
-Pa_StreamTime() returns the number of samples that have been generated.
-PaTimeStamp is a double precision number which is a convenient way to pass
-big numbers around even though we only need integers.
-<blockquote>
-<pre>PaTimestamp Pa_StreamTime( PortAudioStream *stream );</pre>
-</blockquote>
-The "CPU Load" is a fraction of total CPU time consumed by the stream's
-audio processing. A value of 0.5 would imply that PortAudio and the sound
-generating callback was consuming roughly 50% of the available CPU time.
-This function may be called from the callback function or the application.
-<blockquote>
-<pre>double Pa_GetCPULoad( PortAudioStream* stream );</pre>
