Embodiment Construction

[0039] At present, people often add their favorite background music in the audio, that is, add sound effects, so that the audio is richer. Sound effects are often added according to the beat of the audio, so the beat detection of a piece of audio is particularly important. The traditional audio beat detection method focuses on audio signal processing, which is prone to misjudgment or missed detection, resulting in poor sound effect characteristics after adding sound effects to the audio according to the detection results. For example, if figure 1 As shown, a piece of audio to be detected is audio m, using the traditional audio detection method to perform beat detection on the audio to be detected, the detected beats are points a1, b1, and c1 marked by the dotted line, the retake is point a1, and the audio The real beat in m is point a, b, and c marked by the solid line, and the retake is point a, that is, there is a certain error between the detected beat and the real beat in...

Abstract

The embodiment of the invention discloses an audio processing method, audio processing equipment and a readable storage medium. The audio processing method comprises the following steps: acquiring anaudio to be detected, performing audio feature extraction on the audio to be detected to obtain audio features of the audio to be detected, and performing beat detection on the audio features of the audio to be detected by using a beat detection model to obtain beats of the audio to be detected and rebeats included in the beats, and adding a sound effect to the audio to be detected according to the beat and the re-beat. The beat detection model in the method is obtained by training based on the training sample and the beat label and the re-beat label corresponding to the training sample, and the beat detection accuracy of the beat detection model is higher than that of a traditional audio signal processing mode for beat detection. Therefore, according to the beat and the re-beat detected by the beat detection model, the sound effect is added to the to-be-detected audio, and the accuracy of the sound effect is improved.

Description

technical field [0001] The present application relates to the technical field of audio processing, and in particular to an audio processing method, an audio processing device and a readable storage medium. Background technique [0002] With the continuous development of Internet technology, short video and live broadcast platforms continue to rise. When users use these platforms to record videos, they usually incorporate changes in the rhythm of the music to improve the audiovisual experience of the video. For example, when shooting short videos (such as Douyin), users often add sound effects according to the rhythm of the music, making the music of the short videos richer. Among them, the beat detection of the audio is an important process before the sound effect adding process. [0003] Traditional audio beat detection methods focus on audio signal processing, such as using information such as frequency domain signal difference, frequency domain energy envelope, time dom...
