SYSTEM, APPARATUS AND METHOD FOR CONSISTENT ACOUSTIC SCENE REPRODUCTION BASED ON INFORMED SPATIAL FILTERING

摘要

A system for generating one or more audio output signals is provided. The system comprises a decomposition module (101), a signal processor (105), and an output interface (106). The decomposition module (101) is configured to receive two or more audio input signals, wherein the decomposition module (101) is configured to generate a direct component signal, comprising direct signal components of the two or more audio input signals, and wherein the decomposition module (101) is configured to generate a diffuse component signal, comprising diffuse signal components of the two or more audio input signals. The signal processor (105) is configured to receive the direct component signal, the diffuse component signal and direction information, said direction information depending on a direction of arrival of the direct signal components of the two or more audio input signals. Moreover, the signal processor (105) is configured to generate one or more processed diffuse signals depending on the diffuse component signal. For each audio output signal of the one or more audio output signals, the signal processor (105) is configured to determine, depending on the direction of arrival, a direct gain, the signal processor (105) is configured to apply said direct gain on the direct component signal to obtain a processed direct signal, and the signal processor (105) is configured to combine said processed direct signal and one of the one or more processed diffuse signals to generate said audio output signal. The output interface (106) is configured to output the one or more audio output signals.
