Abstract

The invention provides a bass compensation automatic switching method and device. The method includes the steps of: performing framing processing on audio signals, and obtaining a current audio frame; calculating energy of low-frequency signals in the audio fame; calculating total energy of all audio signals in the audio frame; calculating the energy proportion of the low-frequency signals of the audio frame in all the audio signals; and determining the on-off state of a bass compensation function according to the energy proportion. The technical scheme provided by the invention does not need a user to manually control switching-on or switching-off of the bass compensation function through a remote controller, realizes automatic switching of the bass compensation function, and enables a television to better give play to bass performance thereof.

Description

technical field [0001] The invention relates to audio processing technology, in particular to a bass compensation automatic switching method and device. Background technique [0002] With the development of electronic technology, the thickness of TV sets is getting thinner and thinner, and the limited space makes the size of speakers also greatly restricted. The size of the speaker has a great influence on the sound performance of the speaker. When the size of the speaker is reduced, the area of ​​the diaphragm and the magnet of the speaker will become smaller, and the pressure when driving the sound to vibrate will decrease accordingly, resulting in the sound of the speaker The volume amplification effect is weakened, and the low-frequency part of the sound cannot be fully expressed, thereby reducing the user experience. [0003] In order to enable the speaker to fully express the low-frequency part of the sound and improve user experience, the existing TVs mostly use bass...
