Embodiment Construction

[0051] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0052] An embodiment of the present application provides a method for detecting rhythm points of audio, and the method can be implemented by a terminal or a server. The terminal may be a mobile terminal such as a mobile phone, a tablet computer, and a notebook, or a fixed terminal such as a desktop computer. The server can be a single server or a cluster of servers.

[0053] The method provided in this embodiment of the present application can be used to detect rhythm points in audio, and the detected rhythm points can be used for some interesting applications. For example, when the audio is played externally, since people's perception of the intermediate frequency rhythm point of the audio is more obvious, during the song playback proce...

Abstract

The invention discloses an audio rhythm point detection method, apparatus and device, and a readable storage medium, and belongs to the technical field of audio processing. The method comprises the steps of obtaining a to-be-detected audio; performing audio rail separation on the to-be-detected audio to obtain a drumbeat audio; and determining multiple types of rhythm points of the to-be-detectedaudio based on the drumbeat audio and a rhythm point prediction neural network model. By adoption of the method provided by the invention, the technical problem of relatively low accuracy of detectingthe rhythm point of the audio in related technologies can be effectively solved.

Description

technical field [0001] The present application relates to the technical field of audio processing, and in particular, to a method, apparatus, device, and readable storage medium for detecting rhythm points of audio. Background technique [0002] The drum kit is a commonly used instrument, and the sound of the drum kit is present in most song audio. Certain time points in the audio of the song at which drum sounds occur may be referred to as drum beats (drum beats may also be referred to as rhythm points). According to the different drum sounds of the song audio in the drum, the drums can be divided into low-frequency drums, mid-frequency drums and high-frequency drums. Among them, the song audio contains the sound of hitting the kick drum in the low-frequency drum, and the mid-frequency drum is hitting the snare drum or drum. The sound of the tom, and the sound of hitting the cymbal in the high-frequency drum. The low frequency, mid frequency and high frequency drums may a...
