Abstract

The embodiment of the invention discloses an audio detection method. The method comprises the following steps: acquiring first digital audio data, and calculating first audio parameter information corresponding to the first digital audio data; outputting the first digital audio data to an audio channel, and receiving second digital audio data returned by the audio channel, wherein the audio channel forms an input-output loop; calculating second audio parameter information corresponding to the second digital audio data; and comparing the first audio parameter information with the second audio parameter information to obtain a detection result.

Description

technical field [0001] The present invention relates to the technical field of audio detection, in particular to an audio detection method and device, and a storage medium. Background technique [0002] At present, electronic devices such as mobile phones and tablets all have audio input and output functions, that is, not only can the digital audio signal be converted into an analog audio signal, and then converted into a sound signal through the speaker to realize the audio output function, but also the sound signal can be transmitted through the microphone. Convert it into an analog audio signal, and then convert the analog audio signal into a digital audio signal to realize the audio input function. [0003] For electronic equipment with audio input and output functions, audio testing must be performed before leaving the factory to ensure that the audio quality requirements can be met. In the background technology, there are mainly two methods to realize audio detection....
