Abstract
Para o propósito de reprodução espacial de um sinal de áudio, este deve ser projetado para as posiçõ caso não ter que ser fixado em uma configuração dnal de áudio. No entanto, um problema aqui é que uma multiplicidade de combinações possíveis existe. No método de acordo com a presente invenção, as fontes sonoras (3) são interpretadas como objetos acústicos com o propósito de projetá-las em uma configuração de alto-falante arbitrária (2). Aqui, um objeto acústico consiste de que além do sinal de áudio uma fonte sonora é atribuída um item de info objeto acústico, a informação espacial da fonte sonora e a posição atual de um alto-falante são usadas para calcular a distância virtual a partir da fonte sonora via o alto-falante para o ouvinte (1). Antes da reprodução, o processamento separado (7, 8, 9) do sinal de áudio para cada alto-falante é
