Audio noise filtering system

Abstract

The invention relates to an audio noise filtering system, which is provided with a mobile terminal and comprises a first audio acquisition module used for acquiring a noise value of an environment where the mobile terminal is located; a second audio acquisition module used for acquiring a target audio of a target sound source; and an audio processing module electrically connected with the first audio acquisition module and the second audio acquisition module, and used for acquiring the noise value and the target audio, comparing the target audio with the noise value, and removing the audio with the same noise value in the target audio. According to the audio noise filtering system, the noise value is independently recorded and compared with the target audio, so that the purpose of removing the noise value in the target audio is achieved, and the effective noise reduction effect is achieved.

Description

technical field

[0001] The invention relates to the field of audio processing, in particular to an audio noise filtering system. Background technique

[0002] With the continuous development of electronic technology, mobile terminals (such as smart phones, tablet computers, etc.) have more and more powerful functions, and play an indispensable role in people's life or work. The audio playback function of the mobile terminal supports users to listen to audio anytime and anywhere. In some noisy occasions, users can also choose to use earphones to listen to audio to isolate surrounding noise. For example, when the user is taking the bus, if the side is very noisy, the user can wear earphones and listen to music to filter the surrounding noise. However, since the spectrum of the played audio is fluctuating, the fluctuation of the spectrum is small at certain moments, and the sound is weak, which cannot effectively filter the surrounding noise.
