Spatial analysis

Spatial analysis is performed on the sound input using time – and frequency representations of the incoming signals. In this way, the incoming sound format is transformed into a 3D representation of a desired sound field, where diffuse sound sources and localizable sound sources become distinguished virtual sound sources. Further, for any localizable virtual sound source is given it’s desired positioning by learning from the stereophonic input where a listener should hear the source from.

Wave field synthesis

Wave field synthesis is used to physically control sound waves propagation in space by combining the sound of several loudspeakers using frequency-dependent levels and delays for each sound source.  

Physical acoustic

Physical Acoustic treatment of the output filtering stage allows us to optimize the sound. As loudspeakers are not ideal point sources but exhibit potentially complex linear and non-linear insufficiencies, we take care to use each loudspeaker at it’s best, minimizing distortion and maximizing output level given a desired frequency response. We want your brand to sound like it should!

Psycho-acoustics

Using Psycho-acoustics we take care to process the incoming sound in a way that will not result in audible and disturbing artifacts when listening. This is assured for any type of content from music listening to movie watching including sports or news material. The sound experience will always be crisp and clear for all sounds that are meant to be heard that way, while ambient sounds are strongly involving, allowing you to enjoy a lot of spaciousness .

Less speakers

In contrast to standard wave field synthesis systems that require ten’s or even hundreds of loudspeakers surrounding the listening area, Sonic Emotion owns unique IP that allows implementing systems with sound field control with only 6 loudspeakers (and an optional subwoofer).  This unique “inversion” of the original wave field synthesis allows to use the most advanced sound field rendering technology “Wave field Synthesis” in home environments and consumer applications such as Soundbars, TVs, Docking stations, PCs and much more!
