StormAudio's mission to create the greatest immersive sound experiences also parlays to headphone users. Integrated into all our processors as a standard feature, is our exclusive SphereAudio binaural immersive sound headphone technology.

SphereAudio is a binaural headphone technology capable of delivering an immersive sound experience, via any standard pair of high-quality stereo headphones. This exclusive headphone technology, powered by Auro®-Headphones™, is available on all StormAudio processors, and delivers an unmatched level of realism.

Designed for multi-room audio distribution, as an addition to the main theater playback, this binaural technology renders any audio source, from Mono to Immersive Sound formats - played back natively or upmixed -, into that of a 3D audio experience over headphones. The result is an immersive soundscape all around you, thanks to the binaural 3D sound reproduction created for headphones. All it takes is connecting a headphone amplifier to the headphone XLR output of the StormAudio processor.

Legacy content in Mono, Stereo or 5.1/7.1 Surround is either played back natively or upmixed through one of the upmixers, whilst content in an Immersive Sound format is decoded via their decoding engines and rendered in their native formats.
After having gone through the necessary decoders and/or upmixers inside the processor, the SphereAudio engine will apply binaural treatment to each audio channel using their spatial information, merging all channels into a binauralized Stereo Headphones signal. The SphereAudio engine will deliver a precise virtual location of these channels to the listener, wearing any standard type of high-quality stereo pair of headphones.

SphereAudio is an exclusive technology provided by StormAudio.

What is binaural technology?

Binaural technology is based on the principle that if a sound reproduction system can generate the same sound pressures at the listener's eardrums compared to what would have been produced by a real sound source, then the listener should not be able to tell the difference between the virtual image and the real sound source.
Unfortunately though, when headphones are used for the reproduction of sound, the virtual image is often perceived as being too close to the head, and sometimes even as inside the head. This phenomenon is particularly difficult to avoid when one attempts to place the virtual image directly in front of the listener.
Binaural technology is compensating those negative effects to recreate a realistic sound image.
