Embodiment Construction

[0051] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0052] The present invention provides an audio signal adjustment method. In the first embodiment of the audio signal adjustment method of the present invention, refer tofigure 1 , the audio signal adjustment method includes:

[0053] Step S10, when the audio signal input by the microphone to the audio output device is detected, the signal peak value of the audio signal is acquired in real time;

[0054] The types of microphones on the existing market are generally divided into dynamic type, crystal type, carbon grain type, aluminum strip type and capacitive type, etc. In order to avoid unnecessary noise, family KTV generally chooses dynamic type microphones. Due to the problem of service life and the user's pursuit of KTV sound effects, etc., users usually need to choose to buy a microphone. The receiver of the microp...

Abstract

The invention discloses an audio signal adjustment method and apparatus. The audio signal adjustment method comprises the following steps: when audio signals input by a microphone to an audio output device are detected, obtaining a signal peak value of the audio signals in real time; determining whether the signal peak value is within a preset identification threshold scope of the audio output device; and when the signal peak values are not within the preset identification threshold scope, performing gain adjustment processing on the audio signals so that the audio output device can identify and play the audio signals after the gain adjustment processing. The method and apparatus solve the technical problem of affecting user experience due to sound effect distortion and abnormities occurring when a television set end plays audio input by the microphone to the audio output device since audio signal amplitude input by the microphone to a television set is not detected in the prior art.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to an audio signal adjustment method and device. Background technique [0002] With the development of science and technology, today's TV is not just a simple audio-visual tool, but a high-end smart electronic product that can meet the entertainment needs of the public. Among them, the home KTV realized on the basis of smart TV is becoming more and more popular among the public. Welcome, in order to improve the effect of KTV, many users will choose to buy microphones by themselves, and if the purchased microphones have a signal amplification function in the corresponding receiver, the corresponding audio signal may appear distorted and abnormal after being broadcast through the TV. Even the problem of damaging the microphone interface will affect the user experience and personal safety. Contents of the invention [0003] The main purpose of the present invention...
