In a way, car audio has similar limitations as headphone listening. When you listen to music over headphones, the soundstage and concert hall shrink to the size of your head! When you listen to music in your car, the soundstage and concert hall shrink to the size of the car. The sound is not a great performance in a concert hall!

Illusonic CarSurround technology generates additional signals which, when emitted with the existing and optional additional transducers, extend the soundstage and space beyond the size of the car.

Input format stereo, 5.1, custom
Immersion Off, weak to strong
Depth/3D Off, weak to strong
Algorithmic delay 0 to 10 ms

Bass Enhancement

Based on physical loudspeaker modeling and psychoacoustic principles, our Bass Enhancement technology extends the frequency range of small loudspeakers to reproduce low frequencies, sounding like a larger loudspeaker.

Input format mono, stereo
Loudspeaker cutoff frequency 40 to 300 Hz
Algorithmic delay 0 to 10 ms

Headphones 3D

Illusonic Headphones 3D is designed for the ambitious listener, converting cues in stereo and 5.1 surround signals to natural headphone listening cues and enhancing the perceived space beyond the head.

Input format stereo, Lt/Rt, 5.1, 7.1
Stage width 60 to 120 degree
Immersion Off, weak to strong
Depth/3D Off, weak to strong
Room Off, weak to strong
Algorithmic delay 0 to 10 ms
Head tracking support gyrometer data

Loudspeaker 3D

Our version of soundbar and “iPod dock” concept: rather than using many transducers, our concept uses the minimum number of transducers necessary for generating a breathtaking spatial effect from a single-box form factor. There are no aliasing and timbral artifacts, known from conventional soundbars.  Immersion and depth/3D are perceived from everywhere in the room. Particularly suited for high-end products, using only few but high quality transducers.

Input formats stereo, Lt/Rt, 5.1
Configurations 2 to 4 transducers
Sound control immersion, depth/3D
Acoustic control left/right spatial balance
Algorithmic delay 4 to 10ms


Illusonic Upmix is the most versatile technology of its kind on the market. Sophisticated signal analysis, spatial hearing modeling, auditory filterbanks, and spatial synthesis processing yield high fidelity discrete-like surround signals.

Any number of front channels are supported for precise sound stage localization and a large sweet spot. Up to 16 independent surround audio channels can be generated. The resulting independent audio channels can be seamlessly downmixed back to stereo. Up to 8 elevated loudspeakers are supported for 3D setups.

Input format stereo, 5.1, etc.
Ouput format 3, 4, 5.1, 7.1, N.1, 3D
Upmix mode normal, matrix, auto
Channel separation up to 40 dB
LFE filter 60 to 120 Hz, order 2 to 4
Algorithmic delay 4 to 10 ms

5.1 Enhancer

It is not easy to mix and produce high quality 5.1 content. Especially for music mixes, it is often difficult to record or generate ambient signals that are suitable to mimick a concert hall faithfully. Consequently, many 5.1 recordings have a suboptimal surround and immersion effect.

The Illusonic 5.1 Enhancer analyzes 5.1 content and optimizes the ambience. The results are enhanced envelopment and 3D immersion, acoustically more transparent loudspeakers, and an enhanced sweet spot area.

Audio format 5.1, 7.1, custom
Strength Off, weak to strong
Algorithmic delay 0 to 10 ms
