This is really crazy. I think it is the biggest breakthrough of headphone technology in the past decades.

with the headphones on, I thought I was hearing the Triads, which I then responded to by taking my headphones off, and then heard silence. At that point, the demo could have ended, for I had been fooled completely.
Sound On Sound
What the Realiser can do is astonishing! My first experience of its speaker-listening illusion left me, quite literally, open-mouthed.
Head Tracking Combined With 24 Virtual Speakers
Head-tracking refers to the technique of processing spatial audio so that the virtual loudspeaker sources heard over headphones do not move even when the user’s head moves.
Without head-tracking virtual loudspeaker sources will move, causing a perceptual anomaly between the auditory and visual scenes. This frequently leads to either a front-back reversal or collapse of the externalised virtual sound-stage, in which the sound sources appear to be either behind the listener or inside their head.
With head-tracking the external sound sources remain in fixed positions, there is no perceptual anomaly, and the virtual sound-stage extends effortlessly around the listener in every direction.
Personalised Sound Based On Your Unique Ears
Using just our two ears we are able to easily pinpoint sounds coming from every direction around us. In most cases our two ears pick up these sounds differently and this, combined with the filtering action of each ear on all sounds that enter the ear canal, allows our brain to figure out where a sound emanates from.
However everyone’s ears have a unique shape and position – even between one’s left and right ears – and this means that everyone hears sounds quite differently. Normally this is not even noticed since we ‘learn’ how to hear from an early age, and our ears only change slowly as we grow older.
Nevertheless if we were able to listen to what another person was hearing through their ears we would probably be confused, and in particular we would complain that the spatial positioning of the sounds were often badly distorted. Sounds that would normally be in front of us might appear behind us, frontal sound imaging is often lost, and the overall timbre of every sound would also be wrong. Of course our brain could learn and adapt to these new ears, but this process might take days or weeks of continuous listening.
The best and easiest solution to this problem is to personalise the playback of the sounds through the headphones so that they recreate how our own ears hear each sound. We do this by measuring how sound propagates from an external source to each ear, and use this to create digital filters that mimic the normal analogue filtering action of each ear. During this measurement process we also determine the distance apart of the ears, and measure the acoustic impact (or reverberation) of the environment on what we hear.
The overall result is a personalised room impulse response (PRIR) that contains all the information needed to accurately recreate how an individual hears an external sound through their own ears. In combination with low-latency head-tracking personalisation ensures that the listener cannot tell whether the sounds through the headphones are real or virtual.
24 virtual Speakers
The Realiser A16 is able to virtualise and head-track 24 virtual sound source positions for 1 independent listener, and 16 virtual sound source positions for 2 independent listeners. These virtual sources can be located anywhere around the listener, but are normally configured to some standard speaker formats, such as those for Dolby Atmos, DTS:X, Auro 3D or even Ambisonics.
The A16 stores multiple ‘virtual listening rooms’ that may contain different virtual loudspeaker configurations, allowing users to quickly swap between different loudspeaker setups.
IMMERSIVE AUDIO CREATION & PRODUCTION
With its precise emulation of studios, auditoriums and dubbing stages, the Realiser A16 is an ideal monitoring tool when creating new immersive audio sound tracks for movies, games or music.
Personalisation results in precise replication of dubbing stages and control rooms

The Realiser A16 brings immersive movie sound to your home, in spectacular fashion, by recreating the virtual acoustics and loudspeakers of cinemas and studios over your headphones. Experience your movies in the best seat in the movie house, and at the intended sound level, without disturbing your neighbours. With dual listener modes, independent head tracking, and decoding for the latest immersive Dolby Atmos, DTS:X and Auro-3D cinematic formats built in, the Realiser A16 brings watching movies in the home to a new level. Other features of the A16, ideal for avid movie watchers, include the tactile output to drive a shaker for sub-sonic reinforcement, and a Direct Bass function that allows the listener to route the LFE channel direct to their ears for extra impact.
