Abstract
In the head-lock mode, headphones operate such that the directionality of sound sources within the audio is locked to the location of the headphones and not to locations within a physical scene. The head-lock mode can reduce the realism of the surround sound simulation due to failure to take into account the rotation or tiling of the user’s head to adjust the directionality of the sound sources. This disclosure describes techniques to automatically provide a more physically accurate surround sound experience by splitting the foreground and background parts of an audio stream. The foreground audio is routed to the user’s headphones in passthrough mode while the background audio is played via external speakers in the user’s environment. The splitting can be achieved using suitably trained machine learning models or other techniques.
