The present disclosure provides a method for realizing a speaker array-oriented multiple filter system and a related device, belonging to the technical field of audio systems. The method includes: merging, before real-time audio processing, filters of a plurality of sound effect modules in an audio signal processing flow offline to form a finite impulse response (FIR) multiple filter network. The present disclosure places most of computation in an offline processing flow by merging the filters of the plurality of sound effect modules in offline convolution, so that the computation amount of real-time processing is greatly reduced.
