Это просто одна из технологий создания псевдообъемного звука малыми затратами при помощи недорогого звукового процессора, вшитая в OEM-балалайку.
У Sony нечто подобное называется Advanced Sound Engine , у Pioneer - Advanced Sound Retriever и т.п.
Основаная задача - окончательно запутать мозг слушателя как на предпродажном этапе, так и после приобретения девайса.

Молиться точно на это не стоит.
Arkamys is a French-based company specialising in digital signal processing. Its audio processing solutions are applied in the sectors of Consumer Electronics and Car audio.
Arkamys was founded in Paris in 1998. The company initially used its patented sound spatialization process to remaster movies and DVDs for the professional entertainment industry. Today its audio enhancement software is implemented in consumer electronic products, such as mobile phones and mp3 players, as well as portable media players and car radios.

И применительно к Car Audio:

Car Audio software

The audio quality in cars suffers from physical constraints linked to security norms and concerns to optimise in- car roominess. Speakers are placed low in door panels which results in a perceived sound “coming from the floor” that is in many cases too lateralized, either coming from far left or far right. Audio reproduction is often unnatural and can lead to a phenomenon called listener fatigue after an extended period of listening.
The aim of Arkamys car audio software is to create a natural audio image with a harmonious positioning of music and voice in front of the driver at windshield level. This is called the sound scene.
The main difficulty is to create this sound scene without changing the car’s speaker configuration. The software implemented on the radio processes the digital signal of any media players (radio, CD, mp3, etc.). The processing has to be optimised for each car model taking into account the specific characteristics of the car’s interior (size, form, number and positioning of speakers) The diversity of car models makes several configurations necessary in order to adapt to different equipment levels from low level stereo systems to high end multi-channel sound systems which reproduce a 5.1 or 7.1 sound over 10 speakers.
