Abstract

The invention discloses an audio signal processing method, device and equipment and a computer readable storage medium, and the method comprises the steps: collecting the amplitude of an audio signal of an audio input channel, and obtaining the maximum audio amplitude of the audio input channel from all the amplitudes; the output volume of the audio signal is adjusted by adjusting the maximum audio amplitude, no matter what kind of equipment or network the audio signal comes from, the adjustment of the maximum audio amplitude of the audio signal can realize the unified processing of the audio signal, and the situation that interfaces configured at a sending end and a receiving end of the audio signal are different and the audio signal is not uniform is prevented. The amplitude of the audio signal is changed before and after processing, and the volume of the sound output by the loudspeaker is suddenly changed.

Description

technical field [0001] The present invention relates to the field of audio processing, in particular to an audio signal processing method, device, equipment and computer-readable storage medium. Background technique [0002] At present, audio devices such as TVs, set-top boxes, or high-definition players are usually equipped with TV interfaces, VGA interfaces, high-definition multimedia interfaces (HDMI), USB interfaces, etc., and these signal source interfaces can receive different types of audio signals. When the user inputs the same volume, the audio signals of the same amplitude from different signal channels undergo audio decoding, audio adjustment, I2S encoding, and power amplifier amplification in sequence, and the output amplitudes are different, so that the user can feel the sudden change in the output sound when switching channels . [0003] In view of the above phenomenon, the inventor found that the main reason for this phenomenon is that the audio signals recei...
