Problems solved by technology

[0003] The inventor found that when using a mobile terminal to make a call, the user hopes to obtain a clearer human voice, and hopes to reduce the noise interference in the environment and improve the call quality of the mobile terminal. In the prior art, the microphone array is used to eliminate the environmental noise, but Due to the various ways users use mobile terminals, the use of microphone arrays will still collect a certain amount of noise, which cannot completely eliminate noise interference

Abstract

The present application discloses a sound processing method, a device and a system. Through analyzing a sound signal, the first frequency information corresponding to the sound signal is obtained. The second frequency information of sound collected at the same time when the sound signal is collected is obtained. According to the first frequency information and the second frequency information, the corresponding relation between the second frequency information and the sound signal is established. When the second frequency information satisfies a preset condition, the sound signal corresponding to the second frequency information is processed. Thus when sound signals are processed, only the sound signal corresponding to the second frequency information is processed, the collection of the second frequency information can be limited within a frequency range, the sound in a needed frequency range can be directly processed, the processing of all sound signals is not needed, the strength of calculation is small, the sound processing is more targeted, and the noise included in the sound can be accurately processed.

Description

technical field [0001] The present application relates to the field of sound processing, in particular to a sound processing method, device and system. Background technique [0002] With the advancement of technology and the improvement of the functions of electronic equipment, people have higher and higher requirements for processing sound with electronic equipment. When processing the collected sound, due to the complex sound components in the environment, the collected sound may include many different voices. [0003] The inventor found that when using a mobile terminal to make a call, the user hopes to obtain a clearer human voice, and hopes to reduce the noise interference in the environment and improve the call quality of the mobile terminal. In the prior art, the microphone array is used to eliminate the environmental noise, but Since the user uses the mobile terminal in various ways, a certain amount of noise will still be collected by using the microphone array, wh...
