Pekka Lundmark, Nokia's President and CEO, has officially held a live immersive audio and video call with Stefan Lindström, Finland's Ambassador of Digitalization and New Technologies.

The call was enabled by the new Immersive Voice and Audio Services (IVAS) codec technology which forms part of the upcoming 5G-Advanced standard. The IVAS codec allows consumers to hear sound spatially in real-time instead of today’s monophonic smartphone voice call experience.

Lundmark demonstrated the distinctive acoustic dimensions that can be experienced with the new IVAS technology to Lindström while calling him from Nokia’s campus in Espoo. 

A Three-Dimensional Sound Experience

Stefan Lindström, said, "The live immersive voice and audio experience enabled by IVAS improves the richness and quality of the call, and the three-dimensional sound experience makes interaction more lifelike and engaging, bringing a wealth of new benefits to personal and professional communication. Immersive communications technology will also take XR and metaverse interaction to the next level."

Lundmark continued, stating that, "We have demonstrated the future of voice calls. This groundbreaking audio technology takes you to the caller’s environment, creating a spatial and massively improved listening experience for voice and video calls, offering significant benefits for enterprise and industrial applications."

Jenni Lukander, President of Nokia Technologies, said, "I am proud of the leading role Nokia’s researchers and engineers have played in creating these innovative immersive voice and audio technologies. Thanks to standardization, the whole world will now benefit from this innovation."

A World-First

The Immersive Voice and Audio Services (IVAS) codec technology enables live spatial audio across any connected devices (e.g. smartphones, tablets or PCs), bringing people together and offering real-life interaction with three-dimensional sound. It is the biggest leap forward in the live voice calling experience since the introduction of monophonic telephony audio used in smartphones and PCs.

The 3GPP IVAS codec standard has been developed by a consortium of 13 companies under the framework of the IVAS Codec Public Collaboration. Nokia has been a leader in these standardization efforts and has contributed major parts of the technology to the standard, including the development of a smartphone-specific format for the IVAS standard. Incorporating this innovation into a worldwide standard is crucial for enabling interoperability among operators, chipset manufacturers, and handset makers, thereby making spatial communication accessible to everyone.

Nokia was able to successfully demonstrate the IVAS technology in a real-time call even though the technology has not yet been implemented in mobile networks. This first live call utilized Nokia’s proprietary Immersive Voice technology to achieve the experience over a public 5G network.

Nokia is a leader in standards development and holds one of the world’s strongest patent portfolios in connectivity technologies. It boasts over 20,000 patent families, with more than 6,000 of them declared essential to 5G.
