What is HDSX?

A completely new sound experience

With HDSX – High Definition Sound Expansion – you experience sound on a whole new level. The only sound expansion method of its kind worldwide allows the 360-degree expansion of the sound stage, with more nuances, more feeling and no sweet spot. A totally new listening experience – regardless of the loudspeaker system or the audio formats used.

The only sound expansion method of its kind worldwide allows the 360-degree expansion of the sound stage, with more nuances, more feeling and no sweet spot. A totally new listening experience – regardless of the loudspeaker system or the audio formats used.

Whether music, sound or speech – sound material enhanced with HDSX simply sounds better. HDSX completely redefines the spatiality of sound – the sound field is dynamically weighted and extended far beyond the physical boundaries of speaker systems, without artificial effects and without restricting the listener’s freedom of movement.

Speaker systems are becoming smaller and more mobile all the time. As a result, the stereo quality of the sound is quickly lost, leaving a confined sound feeling. HDSX frees the sound from this physical constraint and makes small speakers sound as if they were much larger and further apart. HDSX is not set to a specific audio channel number. From stereo to surround sound to 3D sound constellations, all imaginable sound fields can be upgraded.

The patented HDSX software works with minimal resource consumption. It does not impair battery life and is therefore ideal for use in mobile devices. The technology can be licensed directly and used in DSPs, CPUs, as a plug-in or as an app.

The sound upgrade for all devices

Perfect sound is no longer a question of hardware. HDSX optimises the spatial listening experience, independent of the speaker system in question. This is unique in the world and immediately audible to everyone: significantly improved sound – dynamic, format-independent and on every terminal end device.

Sound sources that are small or installed close to each other sound much better thanks to HDSX. This gives designers completely new freedom in the creation of future devices. Whether it’s a smartphone, tablet, notebook, wearable, earable or WiFi/Bluetooth speakers, HDSX kicks in at the point where the hardware reaches its limits, thereby providing a new quality of small speaker entertainment.

Without HDSX, speakers can only radiate in one direction. With HDSX, they emit an isolated and large-format 360-degree sound field which uniformly irradiates the entire auditory space and does not require a sweet spot. The sound material is reweighted three-dimensionally in its energetic direction and its space. The resulting expansion of the sound field significantly improves listening pleasure and maximises the mobility of sound.

Powerful

HDSX sounds big – no matter how small the device is.

Compatible

As a software solution HDSX can be ported to every platform.

Resource-efficient

HDSX does not impair battery power.

The sound is epic

Home Entertainment

Get info

With HDSX, actors and special effects in films made for the big screen can at last be understood perfectly in the living room at home. HDSX expands the spatial and sonic dynamics of speech, music and special effects, thereby adapting the cinematic mix to the possibilities of small TV speakers. The result is clear word intelligibility and great cinema, even if the TV speakers are mounted on the back of the unit or down firing.

Movies are designed for large cinemas and not for watching on TV in the living room. With HDSX, the sound field is formed not behind the device, but around the device. This means that the sound – even with devices mounted directly on the wall – reaches the audience’s auditory field optimally and in full size and transparency. And all without a sweet spot – which means that everyone can sit where they want.

In addition, HDSX allows the realisation of 3D systems with or without rear speakers. A soundbar or a TV with speakers on two listening levels arranged one above the other radiates sound energy and spatiality in such a coordinated way that the perceived sound space opens upwards. The position of the speech remains freely selectable in height.

Problem solver

Wall-mounted devices with rear-facing sound sources benefit in particular from HDSX.

Special effect

The spatial sound of movies is dynamically optimised for the respective device.

3D experience

HDSX makes multichannel 3D sound possible.

Sounds fantastic, naturally

Headphones

HDSX allows you to get great sound from even the smallest headphones. The listening experience is more like that of the great outdoors. The sound is so large and balanced in range, height and width that you quickly forget the headphones.

By expanding the sound stage in all directions, HDSX eliminates in-head effects. All sound components can be located precisely. This means that the entire sound field can be perceived more intuitively and more intensely. The original sound is not distorted or masked by artefacts. This makes HDSX sound absolutely natural and fatigue-free.

Without HDSX, the sound is passed directly into the auditory canals without the normally buffering air space in between. This makes it seem small and piercing after a prolonged period. HDSX brings this airiness back into the headphones, significantly improving the sound experience, whether for music, movies or gaming.

Kind to the ears

No fatigue, no in-head effects – HDSX sounds absolutely natural.

Surrounded by sound

Forget the headphones – enjoy the sound.

Balanced down to the last detail

Whether music or speech – even the quietest nuances can be located precisely.

Harmonising ceiling speakers

Ambience

Get info

HDSX fills sound gaps in large rooms, e.g. on cruise ships, in hotels, restaurants or at airports – without the need to change the already installed system. Sound holes, fluctuating volumes and unintelligible announcements become a thing of the past.

If ceiling or wall loudspeakers are installed far apart from each other, sound holes with too little sound pressure are often created. Simply increasing the volume is not a suitable solution in this case because it then becomes too loud in other places.

On a higher level

Instead, HDSX stabilises and expands the sound – in real time and in high-end quality – and thus enhances existing sound systems very noticeably. This saves a lot of time and money as there is no need to reinstall the hardware or change to the mostly complex speaker systems. As a pure software solution, HDSX automatically fills the sound gaps between the loudspeakers and optimises their dynamic radiation response in the full frequency spectrum. The result is the uniform and significantly enhanced sound coverage of large rooms, while complying with all standards and without necessitating the constant manual adjustment of the volume.

Great listening!

Large rooms in particular can be filled with sound perfectly with HDSX.

More movement!

Consistently optimised sound creates a positive listening experience for your customers.

Benefits

No sweet spot

Optimal sound – anywhere in the room. With HDSX, the listener enjoys maximum freedom of movement.

No artificial effects

The sound expansion is based solely on the original audio material.

Creative freedom

With HDSX, product designers can think in completely new directions.

Smart and efficient

HDSX is a software solution and works extremely resource-efficiently.

Sound in 3D

HDSX extracts the reflections that occur in the upper spatial level of a stereo recording. This means that a second, raised loudspeaker level is fed separately. The advantage of enhanced listening, which is normally reserved solely for complete 3D systems, is translated into a sound unit and can be integrated into any device.
