Although screen resolutions have improved to match those of fixed devices (TVs, computer screens, etc.), the actual viewing window has been confined to a reduced size, rarely measuring more than 16cm diagonally. With the advent of smartphones in 2007, and the never-ending diversification and growth of consumed smartphone content (films, music, video games, videoconferencing, etc.), audio-visual quality has been a key focus. Orange has been conducting considerable research on 3D sound for about 20 years now. However, such deployment raises questions about the perception of such a scene. Binaural thus seems ideal for smartphones to roll out as a consumer feature and could be a way of enhancing user experience on mobiles.įull Article Binaural audio, a smartphone sound revolution?ģD sound provides an opportunity to deploy the sound stage outside the screen, all around the user, thereby potentially enhancing their immersion. ![]() So, an app developer does not have to worry about the actual distance between user and phone, but simply has to place the user in a virtual space, where the phone’s camera would be. ![]() The focus is instead on the headset, which allows the deployment of a 3D sound technology of its own: binaural rendering that simulates an impression of sound spatialisation.Īn experiment conducted by Orange research teams has shown that to deliver an audio-visual binaural experience, a person’s actual environment and distance from their phone do not matter. However, most phones only have one speaker, making it impossible to spatialise a sound, even minimally. 3D sound allows the sound stage to be deployed outside the smartphone’s screen, all around the user, thereby potentially enhancing their immersion. 3D sound allows the sound stage to be deployed outside the smartphone's screen, all around the user, thereby potentially enhancing… Summary ![]() Summary Orange has been conducting considerable research on 3D sound for about 20 years now.
