  • the audio switching method when the lengths of the first audio segment and the second audio segment are not integer multiples of the preset length, the audio switching method further includes:
  • L f is the number of the extended sampling points
  • L o is the number of sampling points of the first audio segment or the second audio segment
  • N is the preset length
  • Int is a rounding operation
  • the second mute segment is spliced to the shorter end of the audio file in the first audio segment and the second audio segment, the length of the second mute segment being the length difference.

  • the number of sampling points included in the next frame data of different encoding modes is different.
  • one frame of data includes 1024 sampling points, in this case, if the audio file is accompaniment
  • the number of sampling points is not a multiple of 1024.
  • the last frame of data needs to be filled with the front sampling point of the original singer audio file, which causes the application to be carried during the subsequent accompaniment and original singer switching process. Come to complex calculation logic.
  • the length of the accompaniment audio file and the original singer audio file can be made consistent by splicing the second mute segment. Therefore, in the spliced audio file, the length of the accompaniment audio segment is The length of the original singer audio clip is the same, that is, one-half of the total length of the entire audio file, that is, the length of the accompaniment audio clip can be obtained by acquiring the total length of the audio file.

Abstract

Les modes de réalisation de l'invention concernent un procédé, un dispositif et un support de stockage pour commutation audio. Le procédé consiste: à acquérir un fichier audio constitué par épissage d'un premier clip audio et d'un second clip audio; lorsqu'une opération de commutation de clip audio est détectée au cours de la lecture du premier clip audio, à acquérir un passage lu courant du premier clip audio, ce passage lu courant étant la distance de la position de lecture courante à la position de départ du fichier audio; et à lire, en réponse à l'opération de commutation du clip audio, les données audio à partir d'une position cible du fichier audio, la position cible étant une position de lecture sur le second clip audio à laquelle correspond le passage lu courant du premier clip audio.
