Bass sensitization method and device

Abstract

The invention relates to a bass sensitization method and device. The method comprises the steps of obtaining the movie sound played by each sound channel in a movie theater sound effect system; determining a preset scene emotion classification model corresponding to the movie sound, determining a sensitization bass signal according to the preset scene emotion classification model, and sending thesensitization bass signal to an audio processing device, so that each sound channel of the movie theater sound effect system correspondingly plays the bass generated by the audio processing device, wherein the bass and the movie sound are played synchronously. Based on this, the corresponding sensitization bass signal is synchronously played when the movie sound is played, so that the perception effect of audiences is improved.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a method and device for enhancing bass. Background technique [0002] Film is a modern art that includes vision and hearing. With the improvement of video resolution, while the audience can see more and more clear and real pictures, they will look forward to the sound of the same quality, which can better restore the emotions that the filmmakers want to express, and even enhance this. to improve the audience's perception of film art. [0003] Among them, from an anatomical point of view, the bass will change the sac in the labyrinth of the inner ear, making people want to move, and the liquid in the semicircular canal of the vesicle will start to rotate due to the bass, making people succumb to the rhythm of the bass . The infrasound around 18Hz is the same as the resonant frequency of the eyeball, so the sound of this frequency is directly related to emotional states...

AI Technical Summary

Problems solved by technology

However, in the current theater sound system, the way to improve the low-frequency sound effect is to increase the number of bass channel speakers for bass compensation, and does not substantially change the low-frequency sound

At the same time, the lower limit of the frequency response of the bass channel speaker used in the traditional 5.1 standard and panoramic sound system film audio technology is only required to be 20Hz, which is difficult to fully reflect the effect of low frequency sound

[0004] To sum up, the performance of the current theater sound system for low-frequency sound cannot keep up with the development level of visual technology, and cannot fully reflect low-frequency sound, which affects the audience's perception of film art
