Embodiment Construction

[0023] The main idea of ​​the present invention is that the first processing module performs low-frequency cutting processing on the received audio signal; the judging module judges according to the sound intensity of the audio signal, and the audio signal whose sound intensity is greater than a preset threshold is a valid signal, otherwise it is an invalid signal; The second processing module increases the volume of the valid signal according to a predetermined ratio, and reduces the volume of the invalid signal or completely cuts off the invalid signal according to a predetermined ratio.

[0024] In order to make the purpose, 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 specific embodiments.

[0025] According to an embodiment of the present invention, an audio processing system for a mobile terminal is provided.

Abstract

The invention discloses an audio processing system and method for mobile terminals. The system comprises a first processing module, a judgment module and a second processing module, wherein the first processing module is used for carrying out low-frequency cutting operation on a received audio signal; the judgment module is used for making judgment according to the sound intensity of the audio signal, wherein the audio signal is judged as an effective signal if the sound intensity of the audio signal is greater than a preset threshold, and the audio signal is judged as ineffective signal if the sound intensity of the audio signal is lower than the preset threshold; and the second processing module is used for enhancing the volume of the effective signal according to a preset proportion and decreasing the volume of the ineffective signal according to a preset proportion or completely cutting the ineffective signal. According to the invention, the tone quality of records can be effectively improved, and tones become clear and full.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an audio processing system and method for mobile terminals. Background technique [0002] With the continuous development of mobile terminal technologies such as mobile phones, the functions of mobile phones are becoming more and more abundant. Currently, most cell phones have voice recording capabilities. [0003] According to the prior art, the mobile phone mainly realizes the recording function of the mobile phone through combinations of circuits such as an audio collection circuit (microphone), an audio amplifier circuit, and an analog-to-digital converter. [0004] When recording with a portable mobile phone, it is generally in a noisy recording environment, so that a large number of invalid sound signals such as sound signals and background noise will be recorded into the mobile phone together, which affects the recording effect of the mobile phone .
