Ithaca and Brooklyn, New York, which provided the app’s authentic and interactive audio foundations — on top of which were laid spatialized voiceover and scene-boosting assets that all serve to take the listener virtually inside X Ambassadors’ world. Added to these naturalistic soundscapes were the song’s stems, now spatially animated as well, such that singers and instruments move dynamically around the listener. With 360 degrees of rotational freedom, the user is placed at the center of the action and can aurally focus on the different sonic elements by pointing their phone in the directions that interest them. Also able to control the volume blend between song and soundscape, each listener’s experience is uniquely different and amplifies the Boom app’s immersive audio storytelling.
