Abstract

The present invention discloses an audio detection method, device and storage medium. The method includes: acquiring an audio signal to be tested and the number of channels of the audio signal to be tested, wherein the audio signal to be tested has a different number of channels an audio signal less than 2, and preprocessing the audio signal to be tested according to the number of channels of the audio signal to be tested to obtain a two-channel processed signal, and then calculating the energy value of the two-channel processed signal, And the channel inversion is detected according to the energy value of the two-channel processed signal, which can effectively detect the channel inversion in the audio signal to be tested.

Description

technical field [0001] Embodiments of the present invention relate to the field of audio processing, and in particular to an audio detection method, device and storage medium. Background technique [0002] Channel inversion refers to the problem that the left and right channels have a phase deviation of 180 degrees. Therefore, when audio files such as songs with channel inversion are played on a single speaker, there will be no sound or very low sound. For example, currently common android mobile phones, mobile phones below iphone 8, bluetooth speakers, etc., all use a single speaker. Therefore, when playing such songs with inverting channels, you will find that the songs can be played normally when you wear headphones or in the scene of dual speakers, but there will be abnormal phenomena such as silence when playing in mobile phones, Bluetooth speakers and other scenes. Contents of the invention [0003] Embodiments of the present invention provide an audio detection met...
