According to the embodiment of the application, the recording function is started in advance, the recording function is closed in a delayed mode, recorded voice audio is processed, the phenomenon that voice recording is incomplete, singing audio and accompaniment audio are misplaced can be avoided, and therefore user experience of singing songs by using a singing application program is improved.
Fig. 2 is a flowchart of audio recording according to an embodiment of the present application, where the method may be applied to a terminal for a collaring user. Referring to fig. 2, this embodiment includes:
step 201, receiving a collusion audio recording instruction corresponding to a target song.
In an implementation, a user may operate a terminal to launch a singing application to log in to his own account. The singing application program is provided with a collusion tag, and a user can click on the collusion tag to enter a collusion page. After entering the collusion page, the server can automatically recommend a song segment for the user to collude, the user can select to collude the song segment recommended by the server, and the user can search the song segment which the user wants to collude through a search box arranged in the collusion page. After the user selects the target song clip of collarband, the server sends the accompaniment audio and lyric information of the collarband song clip to the terminal, the accompaniment audio also has a corresponding mark file, and the mark file can record three preset playing time points of the accompaniment audio, namely a first preset playing time point, a second preset playing time point and a third preset playing time point. The terminal can play or stop playing the accompaniment audio according to the markup file. In the collusion process, the accompaniment audio can be played at a first preset playing time point, and the accompaniment audio can be played at a second preset playing time point. In the process of singing, the accompaniment audio can be played at the second preset playing time point, and the accompaniment audio can be played at the third preset playing time point. In the collarband page, a recording starting option is further set, and the user can click on the recording starting option, namely a recording instruction of the collarband audio is triggered.
Step 202, when a first preset time period is received after a collusion audio recording instruction is received, recording of the voice audio of the first segment of the target song is started.
In implementation, a first preset duration is set in the singing application program, and when the elapsed duration reaches the first preset duration after the user clicks the record starting option in the collarband page, the terminal starts the recording function to start recording the vocal audio (i.e., the collarband vocal audio) of the first segment of the target song selected by the user.
Step 203, when receiving the collusion audio recording instruction for a second preset time period, playing the accompaniment audio of the target song from the first preset playing time point.
In implementation, a countdown function is set in the singing application program, and the countdown duration is equal to the second preset duration and is greater than the first preset duration. After the user clicks the recording starting option, starting a countdown function, and after the countdown is finished, starting to play the accompaniment audio from a corresponding first preset playing time point in the accompaniment audio by the terminal, namely starting to play the accompaniment audio of the first segment of the target song. In addition, the terminal also can display the countdown information in the collarband page, and the countdown information can be in a mode of displaying a countdown time progress bar or displaying a countdown seconds number so as to remind the user to start to prepare for collarband.
For example, the user selects a piece of a song to be collared on the collage page and clicks on the start recording option. At this time, a countdown time progress bar is displayed on the collarband page, for example, the countdown time period is 3 seconds, that is, the second preset time period is 3 seconds. After the recording start option is clicked for a first preset duration, for example, 2.5 seconds, the terminal starts the recording function. After 0.5 second, the countdown of 3 seconds is completed, the terminal starts playing the accompaniment audio, if the first preset playing time point set in the accompaniment audio is 1 minute and 5 seconds, the terminal starts playing the accompaniment audio from 1 minute and 5 seconds of the accompaniment audio, and meanwhile, the user can collude the selected song segments according to the lyrics prompt.
Step 204, finishing recording when the accompaniment audio is played to a third preset time length after the second preset playing time point, and generating the collarband audio based on the recorded voice audio and the accompaniment audio, wherein the first preset playing time point and the second preset playing time point are respectively the starting time point and the ending time point of the first segment of the target song.
In implementation, the terminal is further provided with a third preset duration, the third preset duration may be equal to or may not be equal to the duration of the first preset duration, the terminal starts to play from the first preset playing time corresponding to the accompaniment audio, after the accompaniment audio is played to the corresponding second preset playing time point, the terminal stops playing the accompaniment audio, namely, the terminal ends playing the accompaniment audio of the first segment of the target song, after the accompaniment audio is stopped playing, the terminal ends the recording function when the elapsed duration reaches the third preset duration, and recorded audio is obtained. Then, the recorded audio is subjected to voice detection, and the starting position and the ending position of the voice are detected. When the starting position of the voice is detected, the detection range is a fixed time length after the recorded voice starting position, wherein the fixed time length can be the difference between the second preset time length and the first preset time length, when the sound volume decibel of the voice is detected to exceed the decibel threshold value, the user is considered to start singing, the time point when the sound volume decibel in the voice exceeds the decibel threshold value is taken as the starting position of the voice, and the voice before the starting position of the voice is cut off. When the ending position of the voice is detected, the detection range is within a third preset time period before the ending position of the recorded voice, when the sound volume decibel of the detected voice is lower than the decibel threshold value, the user is considered to finish singing, the time point when the sound volume decibel of the voice is lower than the decibel threshold value is taken as the ending position of the voice, and the voice after the ending position of the voice is cut off. And finally, taking the audio after the shearing treatment as recorded voice audio. I.e. the user has completed singing the first segment of the target song, the point in time when the first segment of the target song starts is the same as the first preset playing point in time, and the point in time when the first segment of the target song ends is the same as the first preset playing point in time. Finally, aligning the starting time point of the voice audio with the first preset playing time point of the accompaniment audio, and then synthesizing the voice audio and the accompaniment audio to generate the collarband audio.
For example, the third preset time period is set to 0.5 seconds, and the second preset play time point is set to 1 minute and 25 seconds. When the terminal plays to 1 minute and 25 seconds of the accompaniment audio, the terminal stops playing the accompaniment, and then stops the recording function after 0.5 seconds.
