Embodiment Construction

[0030] The technical solution provided by the present invention is: when amplifying the audio signal, the amplification factor of the audio signal representing the live sound in the audio signal is smaller than the amplification factor of the audio signal representing the background sound, and is used to output the amplified audio signal, The live sound in the audio signal is amplified less, and the background sound is greatly amplified, so that the stronger part of the sound is suppressed, while the weaker part is strengthened, thereby reducing the live sound and increasing the background sound.

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Abstract

The invention is suitable for the technical field of audio processing, and provides an audio processing device and an audio processing method for a multimedia device. The audio processing device comprises an audio signal input module, an amplification control module and an output module, wherein the audio signal input module is used for processing received audio signals; the amplification controlmodule is used for amplifying the audio signals, an amplification coefficient x is adopted to amplify the audio signals representing live broadcast sound, and an amplification coefficient y is adopted to amplify the audio signals representing background sound, wherein the amplification coefficient x is smaller than the amplification coefficient y; and the output module is used for receiving the audio signals output by the amplification control module and converting the audio signals into sound to be output. The technical scheme provided by the invention enables the live broadcast sound in theaudio signals to obtain a smaller amplification coefficient and enables the background sound to obtain a bigger amplification coefficient, thereby lowering the live broadcast sound and raising the background sound to better satisfy the requirements of users.

Description

technical field [0001] The invention belongs to the technical field of audio processing, and in particular relates to an audio processing device and an audio processing method for a multimedia device. Background technique [0002] At present, multimedia devices such as television sets and video disc players have been widely used, greatly enriching people's leisure life. [0003] The multimedia device also plays sound while playing images, so as to satisfy users' audio-visual requirements. Usually, the sound data is transmitted through different channels, so that the user can control the sound data of each channel to achieve the purpose of selecting the desired sound. However, when watching some live broadcast programs, such as Olympic games and interactive entertainment programs, the sound of live commentary and live sound (background sound) are mixed together, such as: the sound of athletes in the background or the sound of on-site spectators and The voices of the live sh...
