Who we are
Neural Sphere Audio, developed by NSYNC.
NSYNC develops binaural rendering software and IP for media and content platforms, desktop and mobile applications, audio devices and embedded processors.
Human hearing at the center
Neural Sphere Audio models the acoustic cues and perceptual mechanisms people use to locate sound. The Neural Sphere Renderer, previously introduced as NeiSa, renders native/discrete multichannel audio for two-ear playback, creating a perceived three-dimensional auditory sphere around the listener.
Sphere names that perceived listening space. It does not name an input format, Ambisonics representation or spherical-harmonic encoding. Upper- and lower-hemisphere rendering depends on the source, configuration and target platform.
Software and content came first
Our work began with software rendering and content workflows. Working renderer implementations span Windows, Android and iPhone / iOS application environments. Higher-compute implementations can accommodate longer filters, more channels and personalized rendering approaches.
Neural-network optimization is used in designing transfer functions from our hyper-BRIR database. The resulting renderer is adapted to each target; this does not imply that every device performs neural-network inference during playback. Optional AI source separation for mono and stereo material is a separate processing stage.
One architecture, multiple integration paths
The portable C/C++ renderer can be integrated into media applications, consumer audio devices, gaming products and embedded processing environments. Ports and evaluations span multiple DSP and application-processor families. Supported inputs and configurations are defined for each integration.
The configuration family extends from Neural Sphere 7.1 and Neural Sphere 7.1.4 to Neural Sphere 7.1.4.4 and Neural Sphere 7.1.8.8. Four-part notation identifies horizontal, LFE, upper and lower channels. It is NSYNC configuration notation; it does not imply that every product supports every configuration.
Development track record
Our experience spans renderer applications, immersive content workflows, processor ports, PoCs, demonstrations and device prototypes across consumer electronics, automotive, software and connected-device environments. These describe engineering experience, not a claim that every project entered commercial production.
Past media collaboration with Kakao Entertainment included approximately 100 immersive K-pop music videos and related productions. The work behind NSYNC has received CES Innovation Awards and a Minister of Culture, Sports and Tourism Commendation in Korea.
From technology to products
SAC is NSYNC’s audio converter in development, powered by Neural Sphere Audio. It is not yet available; product-specific inputs and rendering configurations will be announced separately. Metascape is a working beta application that combines source separation and AI-assisted upmixing with rendering. Our longer-term direction connects immersive content creation and playback.
