Embed ai3™ and ai3-nano™ to give all of your products the sense of hearing

What are ai3™ and ai3-nano™?

ai3™ and ai3-nano™ are embedded software platforms that provides a simple API to inform you when a specific audio event or acoustic scene is present, enabling your product to react to it.

ai3™ is designed for a wide range of device types, while ai3-nano™ is specifically designed for true-wireless earbuds or products required to run in always-on mode, such as smartphones, where power efficiency is critical.

They are delivered as a comprehensive SDK, including cross-platform C libraries, reference implementations, custom sound recognition debugging tools and well-documented APIs.
