W artykule przedstawiono zagadnienia rejestracji dźwięku z wykorzystaniem przestrzennych układów wielu mikrofonów. Omawiana problematyka dotyczy tzw. beamforming'u, modelowania przestrzennych charakterystyk kierunkowych matryc mikrofonów, a także współczesnych technologii realizacji nagrań wielokanałowych z przeznaczeniem do odtwarzania w systemach dźwięku przestrzennego.
W artykule opisano możliwości wykorzystania jednopunktowego mikrofonu surround do wyznaczania kierunku źródła dźwięku (Sound Source Localization - SSL). W eksperymentach zastosowano mikrofon "soundfield" z czterema przetwornikami (kapsułami) o charakterystykach kardioidalnych. Specjalna konstrukcja mechaniczna powoduje, że przetwornik w całości posiada charakterystykę dookólną. Mikrofon...
The paper describes operation algorithm and equipment as well as software installation of a detector enabling a visual evaluation of acoustic perspective and dominating sound source direction in multi-channel registration and transmission of spatial sound. Proposed system may be successfully used in modern sound engineering studios, including “live” transmissions.
