Discover the full potential of your audio content with SoundNodes' powerful and intuitive audio recognition and monitoring tools.

We are building the future of audio intelligence by redefining broadcast solutions with AI-powered technology.

SoundNodes (spin-off of OPNS, active in the broadcast industry since 1990) is a Belgian technology-oriented company.

For over 30 years, the broadcast division of OPNS has been a leader in software solutions and audio intelligence technologies for major players in the broadcasting industry. Building on this experience, we are thrilled to announce the next phase of our journey with the birth of SoundNodes.

With the same core objectives and products, but with a dedicated focus on the intersection of broadcast and artificial intelligence, SoundNodes will continue to develop and improve upon the innovative and specialized software solutions that our clients have come to trust, including:

  • DigiPlan: a comprehensive traffic management system.
  • CastLan: a multi-channel audio over IP broadcasting solution.
  • AudioSpy: a multi-stream multimedia logging system.
  • RadioSpy: a versatile multi-band monitor offering alerting and remote listening for out-of-reach transmitters.
  • SoundID AI: an automatic content recognition system based on Artificial Intelligence.



Now, with a clear vision and a commitment to stay at the forefront of innovation in the media industry, we are taking our products and services to the next level. Our SoundID technology, powered by an in-house AI-based audio content recognition system, has already set the industry standard for analyzing thousands of media channels in real-time, as well as the revolutionary milestone of being able to discover music even in the hardest conditions (music as background, noisy environment, speech music, etc.).

As we move forward, we are committed to providing our customers with even more advanced tools and solutions to analyze and understand their audio content seamlessly and continuously.

At SoundNodes, we believe that our long history of working with media clients, coupled with our focus on the future, will allow us to better serve our clients and offer them the latest in cutting-edge technology. Our team brings years of experience adding value to our partners in the media industry, and we are excited to continue providing broadcasters, advertisers, artists, and monitoring and regulation companies with the latest technologies and solutions.

We look forward to working with you and continuing our journey together. Join us as we move forward, and let’s make some noise!

What people say?

Through this collaboration, we have found advice on quality, availability and flexibility. Not to mention a common language and geographical proximity, their philosophy allows us real interaction: we move the product forward together. We imagine a common path to reciprocally evolve the technologies used.

[...] this company is a flagship. Potentially a world leader in its field. Marc Boitel and his team have succeeded in developing a technology capable of automatically recognizing the radio you are listening to or even a specific advertisement on any channel.
