The Synthesis ToolKit in C++ can be used in a variety of ways, depending on your particular needs. Some people just choose the classes they need for a particular project and copy those to their project directory. Others like to compile and link to a library of object files. STK was not designed with one particular style of use in mind.

OVERVIEW:
The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. STK was designed to facilitate rapid development of music synthesis and audio processing software, with an emphasis on cross-platform functionality, realtime control, ease of use, and educational example code. The Synthesis ToolKit is extremely portable (it's mostly platform-independent C and C++ code), and it's completely user-extensible (all source included, no unusual libraries, and no hidden drivers). We like to think that this increases the chances that our programs will still work in another 5-10 years. In fact, the ToolKit has been working continuously for nearly 10 years now. STK currently runs with "realtime" support (audio and MIDI) on SGI (Irix), Linux, Macintosh OS X, and Windows computer platforms. Generic, non-realtime support has been tested under NeXTStep, Sun, and other platforms and should work with any standard C++ compiler.

The Synthesis ToolKit is free for non-commercial use. The only parts of the Synthesis ToolKit that are platform-dependent concern real-time audio and MIDI input and output, and that is taken care of with a few special classes. The interface for MIDI input and the simple Tcl/Tk graphical user interfaces (GUIs) provided is the same, so it's easy to experiment in real time using either the GUIs or MIDI. The Synthesis ToolKit can generate simultaneous SND (AU), WAV, AIFF, and MAT-file output soundfile formats (as well as realtime sound output), so you can view your results using one of a large variety of sound/signal analysis tools already available (e.g. Snd, Cool Edit, Matlab).

The Synthesis Toolkit is not one particular program. Rather, it is a set of C++ classes that you can use to create your own programs. A few example applications are provided to demonstrate some of the ways to use the classes. If you have specific needs, you will probably have to either modify the example programs or write a new program altogether. Further, the example programs don't have a fancy GUI wrapper. If you feel the need to have a "drag and drop" graphical patching GUI, you probably don't want to use the ToolKit. Spending hundreds of hours making platform-dependent graphics code would go against one of the fundamental design goals of the ToolKit - platform independence.

For those instances where a simple GUI with sliders and buttons is helpful, we use Tcl/Tk (http://dev.scriptics.com) which is freely distributed for all the supported ToolKit platforms. A number of Tcl/Tk GUI scripts are distributed with the ToolKit release. For control, the Synthesis Toolkit uses raw MIDI (on supported platforms), and SKINI (Synthesis ToolKit Instrument Network Interface, a MIDI-like text message synthesis control format).

SYSTEM REQUIREMENTS:
See the individual README's (eg. README-linux) in the /doc directory for platform specific information and system requirements. In general, you will use the configure script to create Makefiles on unix platforms or the VC++ workspace files to compile the example programs. To use the Tcl/Tk GUIs, you will need Tcl/Tk version 8.0 or higher.

WHAT'S NEW (AND NOT SO NEW):
Despite being available in one form or another since 1996, we still consider STK to be alpha software. We attempt to maintain backward compatability but changes are sometimes made in an effort to improve the overall design or performance of the software. Please read the Release Notes to see what has changed since the last release.

A new StkFrames class has been created to facilitate the handling and passing of multichannel, vectorized audio data. All STK classes have been updated to include tick() functions that accept StkFrames arguments.

The control message handling scheme has been simplified greatly through the use of the Messager class. It is now possible to have access to simultaneous piped, socketed, and/or MIDI input control messages. In most cases, this should eliminate the use of the Md2Skini program.

Realtime audio input capabilities were added to STK with release 3.0, though the behavior of such is very hardware dependent. Under Linux, Macintosh OS-X, and Irix, audio input and output are possible with very low latency. Using the Windoze DirectSound API, minimum dependable output sound latency seems to be around 20 milliseconds or so, while input sound latency is on the order of a hundred milliseconds or more!

As mentioned above, it is possible to record the audio ouput of an STK program to .snd, .wav, .raw, .aif, and .mat (Matlab MAT-file) output file types. Though somewhat obsolete, the program Md2Skini can be used to write SKINI scorefiles from realtime MIDI input. Finally, STK should compile with non-realtime functionality on any platform with a generic C++ compiler.

PERRY'S NOTES FROM THE ORIGINAL DISTRIBUTION:
This whole world was created with no particular hardware in mind. These examples are intended to be tutorial in nature, as a platform for the continuation of my research, and as a possible starting point for a software synthesis system. The basic motivation was to create the necessary unit generators to do the synthesis, processing, and control that I want to do and teach about. Little thought for optimization was given and therefore improvements, especially speed enhancements, should be possible with these classes. It was written with some basic concepts in mind about how to let compilers optimize.

Your question at this point might be, "But Perry, with CMix, CMusic, CSound, CShells, CMonkeys, etc. already cluttering the landscape, why a new set of stupid C functions for music synthesis and processing?" The answers lie below.

Realtime audio support for Linux currently includes the Advanced Linux Sound Architecture (ALSA), the JACK low-latency audio server, and/or Open Sound System (OSS) APIs. One or more APIs are selected during compilation using the __LINUX_ALSA__, __LINUX_JACK__, and/or __LINUX_OSS__ definitions. Because the ALSA library is now integrated into the standard Linux kernel, it is the default audio/MIDI API with STK versions 4.2 and higher. The __LINUX_ALSASEQ__ definition is required to compile RtMidi with ALSA sequencer support. Native OSS MIDI support no longer exists in RtMidi. If the __LINUX_OSS__ preprocessor definition is specified, only OSS audio support will be compiled and RtMidi will still be compiled using the ALSA API. For this reason, STK now requires the asound library for realtime support. Realtime programs must also link with the <TT>pthread</TT> library. The OSS audio API can be selected by passing the "--with-oss" option to configure.
The free version of OSS generally works as well (and in some cases better than the commercial OSS version ... such as with my Maestro 2e chipset). In general, the ALSA drivers also seem to perform well. You can read more about ALSA at http://www.alsa-project.org/. ALSA is open source and holds great promise for audio under Linux.

The project Makefiles are created by configure. If you have trouble running "make", try invoking "gmake" (for GNU make). If that doesn't work, try to download the GNU Makefile utilities from the Internet.
Another issue that has crept up with this release is proper compiler support for C++ error handling. If you experience problems, you probably don't have a recent version of the C++ compiler. Otherwise, STK should compile and run on SGI platforms without any problems. Release 4.0 of STK is confirmed to compile (with various warnings) using CC version 7.30.
With STK version 4.3, realtime support for IRIX has been discontinued due to the inability to test it. If you need realtime support on an SGI, go back to version 4.2.1. Release 4.0 of STK is confirmed to compile (with various warnings) using CC version 7.30.

/*! \page crealtime Realtime Audio (callback)
The previous section described the use of the RtWvOut class for realtime audio output. The RtWvOut::tick() function periodically pauses program execution in order to send a buffer of audio data to the computer's audio hardware (referred to as blocking functionality). These pauses will effectively limit a program's computations to the correct number of samples per second, which is defined by the sample rate of the hardware.
An alternative scheme for audio input/output is to define a specific
function in which audio computations are performed and to let the
audio system call this function when more input/output data can be
accepted by the hardware (referred to as a callback scheme). In this
section, we show how the previous <TT>rtsine.cpp</TT> program can be
modified to work in a callback scenario. There is no "single-sample"
interface for this functionality. The callback function will be
invoked automatically by the audio system controller (RtAudio) when
new data is needed and it is necessary to compute a full audio buffer
of samples at that time (see \ref callback for further information).

The previous section described the use of the RtWvOut class for
realtime audio output. The RtWvOut::tick() function writes data to a
large ring-buffer, from which data is periodically written to the
computer's audio hardware via an underlying callback routine.
\include crtsine.cpp
The sinusoidal oscillator is created as before. The instantiation of RtAudio requires quite a few more parameters, including output/input device and channel specifiers, the data format, and the desired buffer length (in frames). In this example, we request a single output channel using the default output device, zero channels of input, the RtAudio data format which corresponds to an <tt>StkFloat</tt>, and the RT_BUFFER_SIZE defined in Stk.h. The last argument is an API-dependent buffering parameter (see RtAudio for further information).

After the digital-to-analog converter (dac) and oscillator are successfully created, it is necessary to provide the audio system controller with a pointer to our callback function. The RtAudio::setStreamCallback() function takes a pointer to the callback function and an optional pointer to data that will be made available in the callback. In this example, we need to pass only the pointer to the oscillator. In more complex programs, it is typically necessary to put all shared data in a <tt>struct</tt> (see the next tutorial program for an example) or make use of global variables.

\section callback Blocking vs. Callbacks
Prior to version 4.2.0, all STK example projects and programs used blocking audio input/output functionality (typically with the RtWvIn, RtWvOut, or RtDuplex classes). In many instances, a blocking scheme results in a clearer and more straight-forward program structure. Within a graphical user interface (GUI) programming context, however, callback routines are often more natural.

RtWvOut, or RtDuplex classes). In many instances, a blocking scheme
results in a clearer and more straight-forward program structure.
Within a graphical user interface (GUI) programming context, however,
callback routines are often more natural.
The RtAudio class provides both blocking and callback routines for all supported audio APIs. It should be noted that it is easy to embed blocking calls within a thread to create "callback-like" functionality. In fact, this is what RtAudio does for those audio APIs which are naturally based on blocking routines (Linux ALSA and OSS, SGI Irix, and Windows DirectSound). It is much more difficult to make an inherently callback-based system work like a blocking scheme. RtAudio attempts to do this with the Linux JACK, Macintosh OS-X CoreAudio, and Windows ASIO APIs, but the result is not fully robust (audio over/underruns are more likely to occur).
In order to allow all STK programs to function with equal proficiency on all supported computer platforms, a decision was made to modify the example projects to use audio callback routines. The result is a more complicated code structure, which is unfortunate given that we generally strive to make STK code as clear as possible for educational purposes. This was especially an issue with the demo program because it is designed to function in both realtime and non-realtime contexts. The use of global variables has been avoided by defining data structures to hold all variables which must be accessible to the callback routine and other functions. Alternative schemes for making control updates could be designed depending on particular program needs and constraints.

\section filerate Why is my file sample rate wrong?
When the FileWvIn class loads a soundfile, it automatically sets its internal read increment based on the soundfile rate and the current STK sample rate. For example, if the current STK sample rate is 44100 Hz and the soundfile rate is 22050 Hz, the read increment, or rate, will be set to 0.5 and the file will be interpolated so that is sounds correct at 44100 Hz. For most cases, this works fine. However, consider the following example:
\code
FileWvIn input( "infile" ); // read an input soundfile
StkFloat sampleRate = input.getFileRate();
Stk::setSampleRate( sampleRate ); // set a new STK sample rate based on the file rate
\endcode
With version 4.3 and higher of STK, the FileWvIn class will be notified of a sample rate change and it will automatically adjust its read rate accordingly. Previous versions of STK did not perform this change and thus, the read rate could end up being incorrect. If you do not want FileWvIn to perform this automatic adjustment, you can call the \c ignoreSampleRateChange() function for a given class instance.
\section tickframe What is the difference between the tick() and tickFrame() functions?
\e tickFrame() functions are provided in classes that can handle multi-channel data. A <i>sample frame</i> of audio data represents a single "slice" in time across many audio channels. The WvIn and WvOut subclasses are the primary classes in STK that currently implement the \e tickFrame() functions. \e tick() functions are used for monophonic classes. Note, however, that the WvIn and WvOut classes also implement \e tick() functions though their behavior is dependent on the number of channels you are working with. For example, if using the FileWvIn class with a monophonic soundfile, then there is no difference between the \e tick() and \e tickFrame() functions (aside from the format of their arguments). But if you have a multi-channel file open, then the single value returned from the tick() function is an average of all the samples in the multi-channel sample frame.
\section computesample Hey, why was the tick() function replaced by computeSample() in various STK classes?
C++ doesn't like overloaded virtual functions. All STK classes that implement a single-sample \e tick() function also provide an overloaded version that takes an StkFrames argument (for vectorized computations). Further, many STK classes inherit from abstract base classes (Instrmnt, Generator, ...) and it is most convenient to define functionality common to all subclasses (like the \e tick() function that takes an StkFrames argument) in only the base class. So, to get around the overloaded virtual function problem, STK now uses the \e computeSample() function as a non-overloaded virtual function that is implemented in all subclasses (it essentially replaces the \e tick() function). Note, however, that the overloaded \e tick() functions are still available to the user ... they are implemented in the base classes.
\section endianness Why does the sound I generated with STK sound like *&#@!?
If the resultant sound generated by an STK program sounds like noise (and you're not doing an MLS experiment), the problem is likely related to the byte "endianness" of your computer. By default, STK assumes "big endian" byte order. If you are working with STK classes on a PC (Windows or Linux), you \e must define the <TT>__LITTLE_ENDIAN__</TT> preprocessor definition \e before compiling. If after reading this you realize you need to make this change, do not forget to recompile all STK classes from scratch.
\section xwindows Why do I get a Tk display error message?
The following error will be printed to your terminal window if you attempt to start an STK tcl/tk interface without the X Server first running:
\code
Application initialization failed: this isn't a Tk applicationcouldn't connect to display ":0.0"
\endcode
Simply start your X server and then try the command again.

The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. STK was designed to facilitate rapid development of music synthesis and audio processing software, with an emphasis on cross-platform functionality, realtime control, ease of use, and educational example code. The Synthesis ToolKit is extremely portable (it's mostly platform-independent C and C++ code), and it's completely user-extensible (all source included, no unusual libraries, and no hidden drivers). We like to think that this increases the chances that our programs will still work in another 5-10 years. In fact, the ToolKit has been working continuously for nearly 10 years now. STK currently runs with "realtime" support (audio and MIDI) on SGI (Irix), Linux, Macintosh OS X, and Windows computer platforms. Generic, non-realtime support has been tested under NeXTStep, Sun, and other platforms and should work with any standard C++ compiler.

The Synthesis Toolkit is not one particular program. Rather, it is a set of C++ classes that you can use to create your own programs. A few example applications are provided to demonstrate some of the ways to use the classes. If you have specific needs, you will probably have to either modify the example programs or write a new program altogether. Further, the example programs don't have a fancy GUI wrapper. It is easy to embed STK classes inside a GUI environment but we have chosen to focus our energy on the audio signal processing issues. Spending hundreds of hours making platform-dependent graphical user interfaces would go against one of the fundamental design goals of the ToolKit - platform independence.
For those instances where a simple GUI with sliders and buttons is helpful, we use <A HREF="http://dev.scriptics.com">Tcl/Tk</A> (which is freely distributed for all the supported ToolKit platforms). A number of Tcl/Tk GUI scripts are distributed with the ToolKit release.

/*! \class RtDuplex
\brief STK realtime audio (blocking) input/output class.
This class provides a simplified interface to
RtAudio for realtime audio input/output. It
may also be possible to achieve duplex
operation using separate RtWvIn and RtWvOut
classes, but this class ensures better
input/output synchronization.
Because this class makes use of RtAudio's
blocking input/output routines, its
performance is less robust on systems where
the audio API is callback-based (Macintosh
CoreAudio and Windows ASIO).
RtDuplex supports multi-channel data in
interleaved format. It is important to
distinguish the tick() methods, which output
single samples to all channels in a sample
frame and return samples produced by averaging
across sample frames, from the tickFrame()
methods, which take/return pointers to
multi-channel sample frames.

\brief STK realtime audio (blocking) input class.
This class provides a simplified interface to RtAudio for realtime
audio input. It is a subclass of WvIn. Because this class makes
use of RtAudio's blocking output routines, its performance is less
robust on systems where the audio API is callback-based (Macintosh
CoreAudio and Windows ASIO).
audio input. It is a subclass of WvIn. This class makes use of
RtAudio's callback functionality by creating a large ring-buffer
from which data is read. This class should not be used when
low-latency is desired.
RtWvIn supports multi-channel data in interleaved format. It is
important to distinguish the tick() methods, which return samples
produced by averaging across sample frames, from the tickFrame()
methods, which return references or pointers to multi-channel
sample frames.
RtWvIn supports multi-channel data in both interleaved and
non-interleaved formats. It is important to distinguish the
