Interview Part 1

Interview Part 2

Interview Part 3


If you are like most people, you probably have several speakers in your home. A sound system. A phone.  A Smart Speaker. And you can connect to each of them. But have you ever wondered why they can’t all connect to each other? So did we. And we fixed it.  

Introducing AiFi®.


At Sound Dimension we have been developing cutting-edge and award-winning audio technologies and sound products since 2013. And with our patented technology Artificial Intelligence Fidelity, AiFi, we are creating the next de facto standard that will revolutionize the world of sound — by connecting speakers, regardless of type, brand, or age, and not only making them play together, but making them sound better together.

AiFi is the proven, patented, and revolutionary technology that makes it possible. And we are now making it available to the world!


Sound Dimension’s vision is to integrate AiFi technology into newly manufactured audio devices at chip level, thereby making AiFi a de facto standard on the market for all connected audio devices – regardless of brand, size or task.

The company’s board believes that AiFi Inside was established as a de facto standard when AiFi achieved a market share per product category of:

  • 30 % on market share for Bluetooth speakers
  • 20 % on market share for smart speakers
  • 10 % on market share for projectors

The company’s goal is to have achieved the above market shares by 2030.
