Celem projektu jest opracowanie technologii i prototypu urządzenia zapewniającego istotne podwyższenie parametrów jakościowych odtwarzania dźwięku w małych pomieszczeniach. Urządzenie będzie realizować polepszenie parametrów jakościowych przetwarzania dźwięku przy pomocy dwóch głównych technologii: 1. Korekcja przy pomocy metod cyfrowego przetwarzania sygnałów (DSP) negatywnego wpływu akustyki małych pomieszczeń na parametry wierności reprodukcji dźwięku 2. Realizacja innowacyjnej metody konwersji cyfrowo-analogowej sygnału audio zapewniającej wyższe niż dotychczas uzyskiwane parametry techniczne oraz efektywność energetyczną Korekcja akustyki pomieszczeń będzie realizowana na drodze elektronicznej modyfikacji sygnału źródłowego poprzez wykorzystanie zaawansowanych metod matematycznego przetwarzania sygnałów dźwiękowych, zarówno w zakresie parametrów fazowych, jak i częstotliwościowych dźwięku. Taka realizacja poprawy akustyki pomieszczeń pozwoli uniknąć kosztownych oraz obniżających komfort warunków mieszkaniowych adaptacji akustycznych przy pomocy tzw. ustrojów akustycznych. W obszarze konwersji cyfrowo-analogowej zakres prac badawczo-rozwojowych zakłada opracowanie innowacyjnej technologii wzmacniacza cyfrowego klasy D, który będzie realizować bezpośrednią konwersję cyfrowego zapisu materiału dźwiękowego na wzmocniony sygnał wyjściowy, który będzie bezpośrednio sterować kolumnami głośnikowymi. Tym samym technologia przetwarzania cyfrowo analogowego audio będzie realizować bardzo innowacyjną koncepcję Power DAC czyli bezpośredniej konwersji C/A mocy. Takie rozwiązanie posiada szereg zalet zarówno od strony funkcjonalnej, jakościowej jak i korzystnego wpływu na środowisko.
