Evaluation of Sound Enhancement in Mobile Device Using Virtual Bass Synthesiss Algorithm
PublikacjaAn experiment conducted to validate possibility of use virtual bass synthesis (VBS) algorithm in a portable computer is presented. The subjective listening tests based on the procedure of pairwise comparison between VBS, based on the so-called missing fundamental phenomenon, and standard bass boost technique are employed. The evaluation was carried out in two types of conditions: in a professional listening room and employing an...

Inteligentna Synteza Niskich Częstotliwości w urządzeniach mobilnych
PublikacjaW pracy przedstawiono algorytm inteligentnej adaptacji parametrów syntezy niskich częstotliwości w urządzeniach przenośnych w zależności od odtwarzanego gatunku muzycznego (Smart VBS). Proponowany algorytm wykorzystuje metody generacji harmonicznych oparte na generatorze funkcji nieliniowych (NLD) i wokoderze fazowym (PV). Dla znalezienia optymalnych parametrów syntezy przeprowadzono testy subiektywne sprawdzające powiązanie parametrów...

AUTOMATYCZNE ROZPOZNAWANIE GATUNKÓW MUZYCZNYCH W APLIKACJI SYNTEZUJĄCEJ NISKIE CZĘSTOTLIWOŚCI W URZĄDZENIACH MOBILNYCH
PublikacjaW pracy został opisany inteligentny algorytm syntezy niskich częstotliwości w urządzeniach mobilnych (Smart VBS). Algorytm Smart VBS rozpoznaje gatunek muzyczny i w zależności od wskazania dobiera optymalne parametry syntezy niskich częstotliwości. Synteza niskich częstotliwości odbywa się z wykorzystaniem metody funkcji nieliniowych (NLD). Modyfikacji podlega wykorzystywana funkcja nieliniowa, liczba oraz poziom wzmocnienia dodawanych...
