Abstract
resumo método de síntese transaural para espacialização de som a presente invenção refere-se a um método para a produção de um arquivo de áudio estéreo espacializado digital a partir de um arquivo de áudio de múltiplos canais originais, caracterizado por compreender: um passo de realização de um processamento em cada um dos canais para o cancelamento de caminho cruzado; um passo de fusão dos canais de modo a produzir um sinal de som; e um passo de filtragem dinâmica e equalização específica para aumentar a dinâmica do som.
