Stride is a domain-specific programming language for real-time sound synthesis, processing, and interaction design. It abstracts hardware and software architectures, simplifying the process of software/hardware integration while giving the user control over the code generation process. These abstractions are defined in Stride systems which represent the inner workings of the target hardware and software, exposing them in a simple and consistent manner across platforms.
Stride enables its user to declare the frequency at which Stride expressions are evaluated and provide the user with the ability to control and fine tune the quality of the sounds they seek. Stride also enables its user to control where expressions get evaluated and computed. This type of control is essential to optimizing code running on a resource constrained system such as a microcontroller. A user of Stride can also design interaction using Stride Reaction, an abstraction to handle asynchronous events.
Although Stride is a textual language inheriting concepts from Unit Generator languages, its basic construct is the streaming operator which makes it conceptually similar to dataflow languages. Stride is not a dynamic unit generator graph manager, but rather a code generator. Additionally, Stride is designed to facilitate both low-level signal processing algorithms and high-level constructs using the same syntax.
Stride is designed around the declarative and dataflow paradigms. The language only has two constructs: block declarations and stream expressions. Stride allows both push and pull programming, achieved by controlling the rate of the signal block, which is the fundamental building block of the language. Stride borrows some of the best features of other programming languages like multichannel expansion, single operator interfacing, multiple control rates, and per sample processing. Stride is also a self documenting language.
