Berkeley, CA — LG Electronics’ newest smartphone LG VELVET began launching in European markets on June. LG VELVET is a part of a new branding strategy for LG Mobile, adopting more expressive names that better fit the individual smartphone. This stylish smartphone comes with several unique highlights, such as the distinctive design with a water droplet-inspired camera, front-back symmetrical curves, and a 6.8-inch, 20.5:9 aspect ratio OLED Cinematic FullVision display that optimizes the viewing experience. With a strong emphasis on immersive audio, VELVET integrates the Stereo Speakers and LG 3D Sound Engine, with the latter capable of analyzing and optimizing the audio output based on the type of content that is playing. Here, Gaudio Lab’s Spatial Upmix enables the LG 3D Sound Engine to intensify the fully immersive experience over headphones or earphones. The Spatial Upmix on VELVET adds dimension and pushes sound in every direction, bringing an immersive audio scene from legacy stereophonic content like music, movies, and games.

What is Spatial Upmix? Why is it different from legacy 3D audio?

Existing 3D audio technologies distort the original audio signal and perpetuate sound quality issues. Like too much editing or over-filtering harms the original pictures, it is quite similar when producing 3D audio. The matrix mixing L/R signals and excessive reverb for making a 3D effect cause the audio distortion, such as spectral coloration and phase distortion. Therefore, audiophiles would not ever want to listen. However, the Spatial Upmix gives your ears a fully immersive experience as if you are in the scene without a manipulated audio signal. Unlike legacy 3D audio technologies, it first extracts each sound object from the stereo mix and then renders (spatializes) them to the 3D sound scene on the basis of binaural rendering technology adopted as part of the next-generation of audio standard ISO/IEC 23008-3 MPEG-H.

How does Spatial Upmix benefit LG VELVET users?

“Immersive sensory experience wherever sound goes,” said Ben Chon, Ph.D., and CSO of Gaudio Lab. “When watching movies and dramas, you would feel as if you are in the same event with the characters as the story unfolds. And when listening to music, you would feel the music come alive and surround you rather than static and flat in one spot.
