A 17-person audio software program firm in Lisbon has 3D-printed replicas of each worker’s ears, heads, and torsos to check acoustic realism, a part of a push to carry theater-quality spatial sound to abnormal headphone listeners. Sound Particles, based in 2016, makes use of the printed fashions for granular acoustic testing primarily based on the premise that every individual’s distinctive anatomy shapes how sound reaches the mind.
The corporate’s core know-how borrows from laptop graphics: it treats particular person sounds as particles in a 3D setting, letting creators place sounds in digital area, assign place and motion, and seize the consequence by digital microphones. That method underpins soundscapes in productions together with *Dune* and *Oppenheimer*. A small variety of base samples will be adjusted into 1000’s of distinct variations, which the crew says makes dense scenes really feel extra pure whereas chopping down on guide enhancing.
The ear-printing program feeds immediately into Sound Particles’ greatest product guess. Most immersive audio at the moment is determined by multi-speaker theater setups, however the firm has spent years constructing customized binaural audio know-how that makes use of a listener’s head and ear geometry to simulate how sound strikes and interacts with the physique. The objective is convincing 3D audio by common headphones, no speaker array required.
The corporate’s product lineup now contains plugins for digital audio workstations, immersive synthesizers, and a 3D sound library. It’s additionally making use of its spatial audio engine to AI growth, producing audio datasets with exact spatial labels and practical environmental noise to coach neural networks for speech recognition and good automobile setting detection.
Sound Particles began with a single foundational query about how sound ought to exist in 3D area, and has adopted that query from Hollywood movie manufacturing to shopper headphones to AI coaching information.
