About:
The Synthesis Toolkit (STK) is a set of C++ classes for audio synthesis and processing, primarily designed for research and teaching. It provides a portable, object-oriented framework for creating musical instruments and audio effects with low-latency. Its main value lies in offering a robust foundation for building custom software synthesizers and exploring digital signal processing algorithms.

Key Features:

C++ class library for audio synthesis
Platform-independent core (via RtAudio)
Includes physical models and wavetable synthesis
Real-time and non-real-time synthesis support

Use Cases:

Developing custom software synthesizers
Prototyping digital signal processing (DSP) algorithms
Academic research in computer music

Alternatives:

JUCE – JUCE is a much larger, full-featured application framework for creating cross-platform plugins and apps, whereas STK is a focused library for synthesis primitives.
Pure Data (Pd) – Pd is a visual programming environment for multimedia, while STK is a code library requiring C++ programming.
