Problems solved by technology

[0005] Since the playback progress provided by the player to the timer is the playback time point of the accompaniment data obtained from the buffer, when the speed of obtaining the accompaniment data from the buffer is uneven, the playback progress provided to the timer is also uneven. This in turn causes the pitch line to move unevenly

Abstract

The application provides a method and a device for controlling movement of a pitch line, and belongs to the technical field of computers. The method comprises: every a preset duration when the play duration of the currently played audio is acquired from the player, determining the play progress deviation value according to the play duration of the currently stored pitch line, determining a targetcalibration value corresponding to the play progress deviation value range to which the play progress deviation value belongs according to a correspondence between the preset play progress deviation value range and the calibration value, determining a moving speed of the pitch line corresponding to the audio within the next preset duration according to the target calibration value and the preset duration, updating the playing duration of the currently stored pitch line, and controlling the pitch line to move based on the moving speed within the next preset duration. With this application, thejitter during the movement of the pitch line may be reduced.

Description

technical field [0001] The invention relates to the field of audio and video, in particular to a method and device for controlling the movement of pitch lines. Background technique [0002] With the development of computer technology and network technology, users can not only use audio applications to listen to songs, but also use audio applications to record songs. Users can choose the songs they sing in the terminal, trigger the terminal to display the song recording interface, and record songs in the song recording interface. Lyrics and pitch lines are displayed on the interface, and the pitch lines move with the recording progress. [0003] In related technologies, in the process of recording a song, the terminal can acquire the current playback duration from the player every preset duration (such as 60 ms, etc.) through a timer, and immediately move the pitch line when the playback duration is acquired to the playback duration, so that the pitch line is moved based on ...
