Abstract

The invention discloses a system for generating a simulation sound effect, which comprises a subframe windowing pre-process device, a first low-pass filtering device, a low frequency oscillation device and a second low-pass filtering device. The subframe windowing pre-process device is used for conducting subframe windowing process on original input voice frequency and obtaining subframe voice frequency signals, the first low-pass filtering device is used for avoiding frequency aliasing caused by excessive frequency shift of the subframe voice frequency signals, the low frequency oscillation device is used for modulating the subframe voice frequency signals and obtaining modulating signals, and the second low-pass filtering device is used for removing noise in the modulating signals. The subframe windowing pre-process device, the first low-pass filtering device, the low frequency oscillation device and the second low-pass filtering device are sequentially connected. The invention further discloses a method for generating the simulation sound effect. The system and the method for generating the simulation sound effect solve the problem of trill generation and filtering in conversion sound effect, can generate more sound effects by adjusting phase modulation parameters of the low frequency oscillation device, and are wide in application.

Description

technical field [0001] The invention relates to the field of computers, in particular to a system and method for generating corresponding analog sound effects by adjusting the phase modulation parameters of a low-frequency oscillation device. Background technique [0002] In the prior art, various sound effects often appear in cartoons to simulate the sound of scenes and certain characters, for example, the terrifying ghost in the valley, the angel elf in the dream, the talking squirrel in the big forest, the UFO appearing Sound effects like alien robots. In early cartoons, the above sound effects were done by voice actors. Even until now, there are still a large number of voice actors who perform dubbing by simulating corresponding sound effects. [0003] The way workers simulate dubbing is not only time-consuming and laborious, but also has relatively limited sound effects. In the prior art, there is no corresponding method for generating analog sound effects, and there...
