Problems solved by technology

However, for mid-to-low-end TV chips, after artificial intelligence processing and then sound enhancement processing, the time required for sound processing may be relatively long, so that the output time of the speaker is later than that of the image, that is, the sound and picture are out of sync. The problem

Abstract

The invention relates to a display device and an audio processing method, and is applied to the technical field of audio processing, the display device comprises a controller configured to perform sound separation and sound effect enhancement processing on acquired first audio data to obtain first target audio data and second audio data; performing gain processing on the first target audio data according to the first gain to obtain second target audio data; performing gain processing on the second audio data according to a second gain to obtain third audio data, the first gain and the second gain being determined according to a sound control mode corresponding to the display device; performing delay processing on the second target audio data or the third audio data so as to synchronize the second target audio data and the third audio data; merging the second target audio data and the third audio data to obtain fourth audio data; and an audio output interface configured to output the fourth audio data. According to the invention, the audio-video time delay can be reduced.

Description

technical field [0001] The present application relates to the technical field of audio processing, and in particular, to a display device and an audio processing method. Background technique [0002] In the TV sound effect architecture, after the input signal source passes through the sound decoder, the audio signal stream is obtained. After further enhancing the sound effect of the audio signal stream through the sound effect enhancement algorithm, the sound is output through the speaker. [0003] The computing power of a TV is not infinite. In addition to processing sound, it also needs to deal with image quality. At the same time, the problem of audio and video synchronization must also be considered. Because the data volume of TV images is relatively large, the images need to be sent to the screen for display immediately after processing, and the sound must be processed no later than the image, so as to maintain synchronization with the screen. [0004] However, audio ...
