Integrate our iOS and Android SDKs to make your Apps respond to Audio watermarks

Intrasonics Software Development Kits (SDKs) allow your app, website or embedded device to respond to inaudible triggers encoded in audio and video content (read more about How it Works).

Intrasonics offer SDKs for Android and iOS mobile platforms and a Javascript Decoder that works in the latest browsers. We have a Hardware SDK that provides a reference design for embedded use. And, if your needs are more specific, we can license our core technology to you as a static library.

Our SDKs include all the components you need to encode our audio watermarks into your content and to integrate our watermark decoders.

We provide full documentation and sample code to help you get started and our support team are always on hand to provide professional advice and assistance to our commercial customers.


The Intrasonics SDK is free to try out on your own local machine and test devices.

To use the SDK in production (in your published app, on your own public website, or in embedded hardware) you must sign a commercial license with Intrasonics.

Our pricing is dependent on the nature and scope of your project. Please contact us to discuss your requirements.
