Holographic sound – Helio

Immersive Reality 360°

A Vivid Idea Where Geometry Becomes Music...

What is Helio?

After years of research and development, a fundamentally new sound has been created. It constructs a realistic spatial environment in the form of a large sphere, capable of restoring and preserving the acoustic volume and other physical properties of the room from the source recording. The resulting effect is comparable to a hypercube in four-dimensional space. It delivers full 180° and 360° sound without any shift in the listener's focal point as they move around the room. Even at a distance of under 1 meter from the stereo system, there is zero distortion! The more spatial the audio in the original recording, the more atmospheric it sounds in Helio. On certain tracks, a single audio source is sufficient to achieve full spatial sound. It is compatible with the vast majority of the global audio catalog – whether it be Mono recordings dating back to the 1930s, or recent releases in Stereo and Dolby Atmos. The technology is seamlessly applied during the final mastering and remastering stages for music, or in post-production for films and games. It features unrestricted compatibility with all mainstream audio codecs and formats. The technology does not rely on artificial intelligence or machine learning algorithms. Yet, every single recording processed in Helio delivers a distinctly individual and unique acoustic signature.

Natural sound full of life

Thanks to Helio sound technology, the voices of renowned singers and the virtuosic playing of musical instruments in old recordings, previously considered lost forever, literally come alive for the listener, taking on a completely new dimension. Furthermore, regardless of the playback medium, whether through headphones or acoustic speaker systems, the perceptual fidelity and emotional impact remain consistent. This exact same effect translates to modern music, movies, and video games.

Music

Playback of recordings featuring vocal and instrumental tracks is delivered in incredible resolution. The vocal timbre, the precise attack and decay of musical instruments, acoustic surface reflections, and object positioning are clearly audible not only across the stereo width but also deep within the soundstage. It achieves the restoration of the full spectrum of polyphony and harmonics, something previously impossible to attain during recording, mastering, or remastering. The result is the sensation of real musical instruments being played right in front of the listener. This applies to both acoustic and electronic instruments. Electronic instruments become distinct spatial objects that acquire acoustic properties such as physicality and sonic density.

Movies

The picture literally comes alive for the viewer, enhancing the actors' performances, deepening engagement with the musical score and emotional arcs, and delivering hyper-realistic sound effects and ambient environments. It generates a binaural presence effect without the need for prior recording on specialized equipment.

Games

Immersive in-game audio gives the gamer a sensation of absolute immersion in the virtual world. Video game sound effects have never been this realistic, nor has gameplay engagement been this profound.

Post-production

Helio-processed samples can be seamlessly integrated with Dolby Atmos or standard stereo in modern post-production workflows. During the mixing phase, the sound engineer can precisely isolate vocals, individual instruments, ambient sounds, and special effects exactly as intended.

Our mission Our mission is to restore music to its true role in human life. We engineer sound that transcends mere background or consumable content, elevating it into an instrument that directly impacts human emotion. We strive for the absolute naturalness of sound and are restoring an invaluable musical heritage, bringing back to life recordings that were considered hopelessly lost for decades. Our technology transforms audio from a functional add-on into a core driver of listener impact.

The History of Heliosound

2008

The formative stage of the project focused on identifying methods to achieve reference-level sound quality on par with high-end equipment. One of the primary objectives was to develop solutions for minimizing latency in audio interfaces, ensuring stable system performance in real time.

2010

In-depth research into analog modeling and audio equipment emulation enabled a detailed analysis of the euphonic harmonics inherent in tube circuits, vinyl, and magnetic tape formats. During this phase, we tested the feasibility of integrating their unique psychoacoustic properties into the future algorithm, which included studying the impact of analog noise on listener perception.

2011

The foundation of this development was a comprehensive analysis of the inherent flaws in traditional playback methods, ranging from classic mono and stereo to more niche formats like binaural, ambiphonic, ambisonic, and multi-channel setups across various audio systems. By anchoring our approach in the phantom center as the primary principle of localization, we completely abandoned the Haas effect. This psychoacoustic technique of using inter-channel delay to widen the stereo image has been the bedrock of audio engineering for decades. Instead, we developed a proprietary DSP algorithm featuring fundamentally different phase-frequency characteristics and a completely new acoustic signature.

2012-2026

Years of research in acoustic physics and psychoacoustics have enabled us to develop an innovative playback method that ensures absolute sonic naturalness. Our technology generates an acoustic environment with nested spatial layers that is identical to a physical space, all without altering the frequency response of the source recordings. Helio sound features the capability for "non-invasive restoration" and highly accurate reconstruction of archival tracks dating back to the 1930s. The technology is fully compatible with all modern hardware, from studio monitors to consumer headphones. We are offering a solution to the systemic industry flaws of recent decades, addressing everything from poor dialogue intelligibility in cinema to the consequences of excessive compression and the loudness wars in music.
