Terminal sound mixing system and playing method

Provided are a terminal sound mixing system and a playing method. The playing method for a mixed sound of a terminal comprises the following steps: S0) providing a plurality of microphones corresponding to a plurality of sounding bodies in an initial environment, also providing a terminal environment of which the type and size correspond to those of the initial environment and a plurality of sound simulation devices, and providing a motion tracking device; S1) simultaneously recording, by the plurality of microphones, sounds of the plurality of corresponding sounding bodies into sound tracks respectively, and simultaneously recording, by the motion tracking device, the motion states of the plurality of sounding bodies into motion state files; and S2) simultaneously conducting, by the plurality of sound simulation devices, motions respectively in the motion states of the sounding bodies corresponding thereto respectively which are recorded in the motion state files, and synchronously playing the sound tracks recorded by the corresponding microphones respectively, thereby playing the mixed sound of the terminal. The present invention can reproduce sounds played by sounding bodies on site, and has a very good sound quality effect.
