I/O is a multiplatform audio graph engine, written entirely in Swift, designed to offer a flexible and high-performance system for creating, processing, and routing audio in real time. The engine provides a comprehensive set of tools to select audio sources, apply effects, generate visualizations, and more. All operations are executed within an audio context, conceived to enable modular and scalable routing. Core operations are performed through nodes, which are linked together to form a processing graph. These nodes can be arranged into simple chains or more complex networks, connecting their inputs and outputs to establish custom signal paths. Typically, processing begins with one or more sources delivering samples at extremely small time intervals—often tens of thousands per second.
The output of each node can be routed to others, mixing, transforming, or processing the audio signal in different ways, enabling sophisticated paths for production, analysis, or final rendering. Thanks to its modular architecture and optimized implementation in Swift, I/O combines design clarity with high performance, ensuring accuracy and low latency across multiple environments.
This demo showcases I/O running on iOS with RealityKit, highlighting real-time audio graph processing in an interactive and spatial context. It demonstrates how audio sources and processing nodes can be dynamically updated in response to changes, making it suitable for immersive experiences.

This demo presents I/O in a macOS environment through a configurable desktop application. It focuses on exploring the engine’s core capabilities—audio routing, parameter control, and real-time processing—allowing developers to experiment with different graph configurations and better understand the system’s behavior in a controlled, non-immersive setting.
Thank you for your interest in our platform. We appreciate your curiosity and are delighted that you are exploring I/O as part of your audio development workflow.
At this stage, the distributed binary package in the form of an xcframework provides support exclusively for iOS and macOS platforms. We are actively working on expanding compatibility to include Android, with support for Linux and Windows planned for future releases.
The project includes two sample applications demonstrating key use cases:
An iOS sample showcasing integration with RealityKit, illustrating how to drive spatial audio experience in interactive environments.
A macOS sample offering a configurable application where parameters can be adjusted to explore and experiment with the engine’s capabilities.
We invite you, as an audio developer, to explore the extended documentation available in the root of the repository under the /documentation directory. There you will find detailed technical guides, installation instructions, examples, and patterns to accelerate your adoption.
