| Abstract(in English) | In live concerts, musical instrument sounds are mixed at vocal microphone, which makes it difficult to mix properly. To enable proper mixing, we separate vocal components from observed signal at vocal microphone in real time. In this paper, we propose an online AuxIVA that specializes in maintaining the vocal band as a sound source separation method for use in live concerts.In addition, the proposed method was evaluated by an objective evaluation experiment simulating the environment of a live concert and a subjective evaluation experiment using actual recording data in a live house. In the objective evaluation experiment, the proposed method obtained higher SDR, SIR and SAR than the conventional AuxIVA. In the subjective evaluation experiment, the proposed method received the highest evaluation in terms of overall quality. |
