Problems solved by technology

If the recorded sound itself has brought "noise", even if the subsequent EQ processing is perfect, the "noise" will be amplified by the power amplifier, resulting in poor audio playback effect

Abstract

The invention discloses an audio processing method and apparatus, a sound box system and a storage medium. The audio processing method specifically comprises the following steps: dividing collected environmental sound according to preset bands, and marking the strength values of the environmental sound of the bands, after a recording instruction is received, dividing audio signals picked up by a microphone according to the preset bands, marking the strength values of the audio signals of the bands, then comparing calibration values of the bands of the environmental sound and the calibration values of the bands of the audio signals with a preset reference sound calibration value, judging audio main sound, all environmental noise and recorded environmental noise, finally performing gain andencoding processing on the audio main sound, and performing attenuation and encoding processing on the all environmental noise and recorded environmental noise, outputting audio digital signals to a back end of the sound box system for playing. The problem that a back end power amplifier cannot reduce the noise, resulting in worse playing effect, is solved, and the playing sound effect of the sound box system is improved.

Description

technical field [0001] The present invention relates to the technical field of audio processing, in particular to an audio processing method, device, audio system and storage medium. Background technique [0002] In the field of sound system, people have always regarded the frequency response, loudness of the speaker itself and the EQ of the power amplifier as the main improvement points to improve the audio effect, but neglected the preprocessing of the audio input power amplifier before amplification. If the recorded sound itself has brought "noise", even if the subsequent EQ processing is perfect, the "noise" will be amplified by the power amplifier, resulting in poor audio playback effect. Contents of the invention [0003] The main purpose of the present invention is to provide an audio processing method, aiming at improving the audio effect when the audio system is playing. [0004] In order to achieve the above object, the audio processing method proposed by the pr...
