Audio Code LicensingCommercial Model For Consumer Apps

For consumer applications such as second screen apps and interactive toys, our audio watermarks consist of a fixed number of data bits transmitted within a fixed time. These bursts of bits are what we call “codes”. It’s simpler to think of these codes as large and unique decimal numbers.

We have a spectrum of codes which we licence in small blocks to our customers on an exclusive basis so that there is never a conflict with multiple customers using the same codes.

Each watermark code we licence to a customer can be inserted into audio or audio+video content to trigger a smartphone or tablet app to respond to an event at a specific time point. Some customers require only a few of these codes, some require hundreds, depending on how many unique trigger events are needed.

Pricing for Unique Audio Trigger Codes

For use in consumer apps such as second screen apps, we charge an annual licence fee per code and the price depends on the field of use. In volumes below 100 codes, our code pricing is as follows:



  • Unlimited Use in TV & Ads



  • Unlimited Use in Radio



  • Unlimited Re-Use

Pricing for Event Engine Codes

To use our Event Engine SDK to enable an audience to play along with a TV show in perfect sync, you need our Event Engine timing codes (non-exclusive licence) and one unique (exclusive licence) Episode ID code per episode of the show you’re making. See our Event Engine summary for details.

The Event Engine timing code licence covers unlimited use for one year for as many episodes and/or show titles as you wish. There are over 1,000 audio codes in the Event Engine timing code package.
