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 MAU 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.
