Abstract

SISTEMA E MÉTODOS PARA MIXAGEM AUTOMÁTICA DE ÁUDIO PARA CENAS ACÚSTICAS. O método implementado por computador divulgado pode incluir obter uma amostra de áudio a partir de uma fonte de conteúdo, inserir a amostra de áudio obtida em um modelo de aprendizado de máquina treinado, obter a saída do modelo de aprendizado de máquina treinado, em que a saída é um perfil de um ambiente no qual a amostra de áudio de entrada foi gravada, obter uma resposta de impulso acústico correspondente ao perfil do ambiente no qual a amostra de áudio de entrada foi gravada, obter uma segunda amostra de áudio, processar a resposta de impulso acústico obtida com a segunda amostra de áudio, e inserir um resultado do processamento da resposta de impulso acústico obtida e da segunda amostra de áudio em uma faixa de áudio. Vários outros métodos, sistemas e meios legíveis por computador também são divulgados.
