Abstract: A sound processing apparatus and a sound processing method thereof are provided. The following steps are included. Multiple first sound signals corresponding to multiple sound reception sources are obtained. A sound source position of a sound source relative to the sound reception sources is determined. A relationship among multiple sound receiving directions corresponding to the sound reception sources is determined according to the sound source position. The sound receiving directions relate to directionality of the sound reception sources. A second sound signal is outputted from the first sound signals based on the relationship among the sound receiving directions. Accordingly, an optimal sound receiving direction corresponding to the sound source can be adjusted automatically, so as to improve sound quality.
