About Switchboard Audio SDK
What Is Switchboard Audio SDK?
Switchboard Audio SDK is a cross-platform development toolkit built on a C++ core with high-level bindings, enabling software developers to design, prototype, and deploy real-time audio features and applications across mobile, web, desktop, and physical devices. It solves the complexity of building and scaling audio engines from scratch by providing a production-ready SDK with open-source example apps that can be remixed for voice, AI, and interactive use cases.
Who Is It For?
The SDK is primarily for software developers building real-time audio into their apps or devices. The companion Switchboard Editor (no-code) supports product managers, innovation leaders, and hobbyists for rapid prototyping and experimentation. It is NOT for non-technical end-users seeking a finished audio app—it is a developer tool for building custom audio experiences.
Real Use Cases
Common applications include voice-enabled mobile apps, AI-powered audio features, real-time communication tools, interactive gaming audio, and prototyping new audio products using the drag-and-drop Editor. Teams in R&D can bring their own algorithms to the SDK and test them with the Editor before deployment.
Key features
- Cross-platform C++ SDK — High-performance audio engine with simple bindings for iOS, Android, Mac, Windows, Linux, and Web.
- Open-source example apps — Ready-to-remix reference implementations for many audio use cases.
