ysound

ysound is a fictional cross-platform open-source library for real-time audio processing, intended for music software, games, and educational use. This article uses ysound as a representative project to illustrate common features of modern DSP toolkits. The design emphasizes a clean, modular structure that supports rapid development of instruments, effects, and audio processing pipelines.

Key features include a modular digital signal processing (DSP) graph, low-latency audio I/O, and a collection of built-in oscillators, filters, envelopes, and effects. The library supports multi-channel audio, MIDI input, and sample-accurate scheduling. It is designed to be easily extended with user-defined modules and third-party plugins.

Architecture and platform support: ysound's core is written in C++ with language bindings for Python and JavaScript. The DSP graph is evaluated on a dedicated audio thread, with a separate, thread-safe API for scheduling events. It targets Windows, macOS, Linux, and mobile platforms, and integrates with common audio subsystems such as Core Audio, ASIO, ALSA, and WASAPI via an abstraction layer.

Usage and licensing: the project is commonly released under an MIT-style license and encourages community contributions through a public repository. It is used in hobbyist game engines, educational labs, and small- to mid-scale music projects. Users typically rely on example projects, tutorials, and a small set of reference implementations to build instruments and effects.
