Definitions
- a non-transitory computer readable storage medium is provided with computer executable instructions. When the executable instructions are run in a computer, the following steps are performed:
- FIG. 2 is a flowchart of an audio switching method according to an exemplary embodiment
- FIG. 4 is a block diagram of an audio switching device 500 according to an exemplary embodiment
- 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.
- step 201 may be mutually synchronized audio files, and in this case, step 202 is not required to be performed.
- 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.
- the total length of the audio file may be changed after being decoded by some decoders of the terminal. In this case, the third method cannot be used to obtain the length of the accompaniment audio segment.
- an audio playing interface may be provided. As shown in FIG. 4, the original playing option and the playing accompaniment option may be provided in the audio playing interface, when the playing is detected. After the trigger operation of the original sing option, the original singer audio segment is played, when it is detected The accompaniment audio clip is played after the trigger operation of the Style option is played.
- step 209 if an audio switching operation is detected during the playing, the terminal acquires the playing length of the currently played audio segment, and the playing length is the distance of the current playing position from the starting position of the audio file.
- the length of the accompaniment audio segment is 15132 sample points
- the playback length is 15283 sample points
- the playing length is one. It is greater than the length of the accompaniment audio segment, and the playback length must be less than the total length of the audio file.
- the audio switching device provided by this embodiment is provided by the first audio segment and the first An audio file in which two audio segments are spliced, and when an audio switching operation is detected, a playback progress jump is performed inside the same audio file, so that the terminal can implement the first audio segment and the second audio by using only one audio file.
- Switching between segments eliminates the need to decode two audio files at the same time, and does not require the decoder to support the decoding capabilities of multi-channel and multi-audio streams, so it is adaptable to all applications.
- the terminal 700 also includes a power source 790 (such as a battery) for powering various components.
- the power source can be logically coupled to the processor 780 through a power management system to manage functions such as charging, discharging, and power management through the power management system.
- Power supply 790 may also include any one or more of a DC or AC power source, a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator, and the like.

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.
