"Audio-Enable" your Web Application

The Intrasonics JS Decoder is an in-browser audio watermark decoder.

SEE A DEMO GET STARTED

The Intrasonics JS Decoder enables a web-browser to automatically respond to hidden audio triggers heard by a microphone.


JS Decoder is 100% Javascript.  No extra software, plugins or browser extensions need to be installed by your users - so long as they have a microphone and a compatible browser, they're ready to go.


The simple setup required for the JS Decoder means that almost any web-based content can be quickly and easily “audio-enabled”.

How does it work?

1

Media is encoded

Using Intrasonics software, inaudible sounds are added to audio and video content in an encoding process called Audio Watermarking.

2

 Codewords detected

The Intrasonics JS Decoder listens via a microphone extracting data from the watermarks it hears.  
The information is then passed to Javascript running in the host web page.

3

Page responds

The web page hosting the JS Decoder is programmed to respond to audio triggers in exciting and engaging ways.
