Build audio apps effortlessly

Simplify audio app development with our cross-platform SDK.

WE WORK WITH
Switchboard is a modular audio SDK that makes it easier to develop audio features and applications without needing to be a specialist in audio programming or C++.

Get to market faster

The Switchboard SDK saves time from prototyping through production and continues paying dividends for products that are cross-platform or have multiple audio features.

Who is Switchboard designed for?
  • AI Agent and Voice AI solutions developers

  • Real Time Communications (RTC) applications

  • Music and social app developers

  • R&D / ML / AI teams looking to commercialize

  • Hardware projects like headphones, speakers, wearables, etc.

  • Pro audio industry - hardware and software

  • Apps & SDKs with audio features

What does it do?

Switchboard is a modular audio framework incorporating a large library of audio nodes AudioNode. These nodes can easily be put together into audio graphs AudioGraph. Switchboard passes these graphs into natively compiled C++ code that runs fast, across multiple platforms including iOS, Android, Mac, Windows, web, and embedded platforms.

Audio graphs can be defined in JSON or native languages, making them easy to build while providing complete flexibility at runtime. Switchboard also has a visual node-based editor, the Switchboard Editor, which generates JSON automatically for rapid configuration of audio graphs that can easily be designed and tested in the browser and deployed to many target platforms.

What are audio nodes?

Audio nodes are essentially containers that process audio and include a wide range of functions such as: speech-to-text, text-to-speech, large language models, voice changers, music or media players, streaming, voice and video calling, the ability to mix and split audio streams, DSP effects, and much more.

Switchboard also includes extensions to many other popular audio tools and SDKs, both open and closed source. We are building an unbiased ecosystem in which developers can easily assemble audio graphs using nodes from any provider, as well as build audio nodes containing their own technology.

Why should I use it?

Whether you’re using it for a single node such as speech-to-text or a voice changer, or stringing multiple nodes together, Switchboard will make it faster and easier to build, test, experiment with, and maintain your product. Not only does this save cost and get you to market faster, it also allows you to rapidly add new features to help drive new growth and revenue opportunities.

How much does it cost?

Switchboard has a free tier up to 20K activations and Commercial Licenses available thereafter. Consult our Pricing page.

Audio is hard. The Switchboard SDK makes it easy.

Switchboard assists developers building new audio products, features and experiments...

  • Without being constrained by the simplified use cases that iOS, Android and other native platforms provide.

  • Without having to build an audio framework from scratch.

  • Without having to rebuild for each platform or operating system.

  • Without having to be experts in audio or low level languages like C++.

Why use it?

Easy-to-use

  • Put together complex audio pipelines without the need for C++ or real-time audio programming.

Automatic volume management

Make an audio engine that sounds the same on iOS, Android, macOS and Linux. Share the same audio code between these platforms.

High-performance

Our audio processing algorithms are highly optimized so you don't need to worry about audio glitches.

Extensible

Our audio processing algorithms are highly optimized so you don't need to worry about audio glitches.

Time saver

Save months or more, especially for complex audio pipelines.

Robust

Avoid writing glue code and validating 3rd party apps. We integrated and tested third party SDKs so you don't have to.

Flexible

Quickly test new audio features, rearrange effects chains, or compare third party extensions.

Customizable

Custom builds and licensing options available—tailored to your needs.

How it can generate an ROI

Switchboard generates a return on investment (ROI) through a combination of cost savings and increased revenue opportunities.

↓ Decreases

  • number of developer hours

  • cost to build

  • maintenance costs

↑ Increases

  • speed to market

  • ease of adding new revenue generating features

A typical example. Note that Switchboard has a free tier. See pricing.
