Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] See figure 1 On the one hand, the present embodiment provides an audio processing method, which includes the following steps: 1. After segmenting the received audio signal, noise samples are obtained and stored one by one; 2. After the audio signal is attenuated, the attenuated The audio signal and the stored noise samples are subjected to op-amp processing to obtain a noise-reduced audio signal; 3. The noise-reduced audio signal is sequentially subje...

Abstract

The invention relates to the technical field of audio devices, and particularly relates to an audio processing method and a system thereof which can improve the pleasant hearing enjoyment of a client.The method comprises the following steps: received audio signals are subjected to segmented processing to obtain noise samples, and the noise samples are stored one by one; after the audio signals are subjected to attenuation processing, the audio signals after attenuation processing and the stored noise samples are subjected to operational amplification processing, and audio signals after noisereduction are obtained; and the audio signals after noise reduction are sequentially subjected to sound change and amplification processing and are transmitted to an outer loudspeaking device. When the technical scheme provided by the invention is adopted, the audio signal quality is improved in the case of listening to a radio and receiving television network broadcast, and the sound speed and the tone are changed according to the habit of the client.

Description

technical field [0001] The invention relates to the technical field of audio devices, in particular to an audio processing method and a system thereof for improving customer's pleasant listening enjoyment. Background technique [0002] With the development of network media and electronic technology, human visual and auditory enjoyment requirements are getting higher and higher. In daily life, audio and video are often played in real time, such as car radio, TV live broadcast, network live broadcast, etc. There are also built-in Walkmans, CD players and other music playback devices, and these audio signals have various popping (POP) sounds, noises, and weird tones, which are unbearable for customers with sensitive hearing. Although with the development of Internet technology, various audio repair software are also provided, but these software can only input an audio file through a large tool such as a computer for later finishing and repairing, which wastes a lot of time, esp...
