Abstract
trata-se de um dispositivo para processar dados de áudio obtém dados que representam versões quantizadas de um conjunto de um ou mais vetores espaciais. cada respectivo vetor espacial do conjunto de vetores espaciais corresponde a um respectivo sinal de áudio do conjunto de sinais de áudio. cada um dos vetores espaciais se encontra em um domínio de ambissônica de ordem superior (hoa) e é computado com base em um conjunto de localizações de alto-falante. o dispositivo quantiza inversamente as versões quantizadas dos vetores espaciais.
