Nokia just made the first phone call using 3D spatial audio

This call, however, was placed over a cellular network using the 3GPP Immersive Video and Audio Services (IVAS) codec, which lets people hear “sound spatially in real-time.” For the uninitiated, spatial audio splits into multiple channels to make it sound like it's coming from different directions. This technology has become pretty popular when streaming music, but video calls are certainly a unique use-case scenario.
