Abstract

The invention discloses a volume adjustment device, method and related equipment, and relates to the technical field of electronic information. It aims to solve the problem in the prior art that it is difficult to ensure that the sound has sufficient strength and texture and contains less noise. The device includes: a first gain adjustment unit, configured to reduce the strength of the audio signal to a first preset strength within a first preset time when the strength of the audio signal is greater than a first threshold; A gain adjustment unit, connected in series with the first gain adjustment unit, configured to reduce the intensity of the audio signal to a first threshold within a second preset time when the intensity of the audio signal is greater than a second threshold Two preset strengths; wherein, the first threshold is greater than the second threshold; the first preset time is shorter than the second preset time.

Description

Technical field [0001] The present invention relates to the field of electronic information technology, in particular to a volume adjustment device and method, and related equipment. Background technique [0002] When playing music, songs and other programs, there may be obvious "squeaking" noises intermittently, which are more common in the sound of instruments, which are pure music places such as the prelude, pass, and end of the song. The root cause of the noise is that the speakers, speakers, headphones, etc. have clipping distortion when the sound is amplified. Because the clipping time is very short, usually more than ten us to tens of us, which is much shorter than the start-up time of ordinary AGC (automatic gain control, automatic gain control), ordinary AGC has no time to suppress it, so it cannot eliminate clipping Noise caused by distortion. [0003] In order to eliminate clipping distortion, simply reducing the start-up time of the AGC will bring other problems. Thi...
