| Abstract(in English) | We have proposed Smart Mixer, novel automatic sound signal mixing method. It has two inputs and improve clarity of one of input sound while maintaining the volume of the other input sound. However, Smart Mixer cannot simply be multi-input, because it was developed on premise of above processing policy, In conventional multi-input mixing method using a smart mixer, a specific input sound is significantly deteriorated. In this paper, we propose a multi-input automatic mixing method to improve clarity of each input sound equally. Furthermore, an example of mixing real acoustic signals using the proposed method is shown. It is shown, that a mixing process that switches between emphasis and suppression can be performed at each point on the time-frequency plane. |
