Abstract
The present disclosure provides a method and an apparatus for simulating the sound characteristics of the audio processor, a terminal device and a storage medium. The method simulates the sound characteristic of a target audio processor by constructing a nonlinear model. The nonlinear model consists of a pre-filter, a saturation characteristic curve, and a post-filter. A high-level signal is sent to the target sound processor, and the target sound processor correspondingly sends out the first output signal, and then the first output signal is filtered and performed spectrum analysis to acquire the frequency response of the post-filter; And a low-level signal is sent to the target sound processor, and the target sound processor correspondingly sends out the second output signal, and then the second output signal is filtered and performed spectrum analysis to obtain a frequency response product of the pre-filter and the post-filter.
