Some audio recording software at present can only record the audio of a user when playing an audio file divided by the accompaniment and the singer voice according to left and right sound channels, and synthesize the audio with part of original singing, so that the user and the original singing are combined; in addition, some software can be used for searching similarly from the cloud to find the accompaniment file conforming to the mixed audio file, and the audio of the user is synthesized on the basis to realize chorus between the user and the original singing. Specifically, when the song file to be played is a mixed audio file, the corresponding accompaniment audio cannot be played in a certain segment time, the corresponding accompaniment audio and the original singing audio are played in another segment time, and the obtained user audio is synthesized to obtain a recorded file, so that the chorus between the user and the original singing cannot be realized, and the experience of listening to songs, K songs and sharing of the user is reduced.

To at least partially address one or more of the above issues and other potential issues, embodiments of the present invention propose audio recording solutions. Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

An embodiment of the invention provides an audio recording method.

Fig. 1 is a schematic flow chart of an audio recording method according to a preferred embodiment of the present invention, it being understood that the method may further include additional blocks not shown and/or may omit the blocks shown, the scope of the present invention is not limited in this respect.

In step 101, according to a recording mode, playing a song file, wherein the song file is a mixed audio file including an accompaniment audio and an original singing audio, and the recording mode is as follows: and playing the corresponding accompaniment audio in the first segment time, and playing the corresponding accompaniment audio and the original singing audio in the second segment time.

Specifically, the client applying the method may include devices such as a song requesting machine, a mobile phone, a computer or a vehicle-mounted terminal. When a user wants to play the K song, the user performs corresponding operation, and the client receives the K song request of the user and plays the song file selected by the user according to the recording mode.

In the embodiment, the song file is a mixed audio file, which includes the accompaniment audio and the original singing audio. In some embodiments, the original audio may also include original audio of multiple singers, such as male and female original sings, or original sings of multiple singers in a band. It should be understood that the method is equally applicable when the song files include an accompaniment audio file and a vocal audio file.

In this embodiment, the recording mode is to play the accompaniment audio of the corresponding time in the first segment time, and play the accompaniment audio of the corresponding time and the original audio of the corresponding time segment in the second segment time. For example, in the time from the beginning of playing a song to the time of playing 46s, playing the accompaniment audio of the corresponding time; and playing the original audio and the accompaniment audio corresponding to the time within 46s to 56s of the played song. Therefore, the original audio of which part is played can be flexibly selected according to the instruction of the user.

In some embodiments, the method of obtaining the first and second fractional times comprises: receiving a selection instruction of a user, wherein the selection instruction is used for obtaining lyrics sung by the user; dividing the playing time of the song based on the time information corresponding to the lyrics sung by the user to obtain a first segment time and a second segment time, wherein the first segment time is the playing time corresponding to the lyrics sung by the user. The playing time of the song is segmented based on the time axis of the lyrics of the song, so that the playing time period of the original singing audio can be accurately divided, and meanwhile, a user can select the lyrics to be sung more intuitively.

Specifically, after receiving the karaoke request, the lyrics selected by the user and sung by the user are obtained based on a selection instruction, and in some embodiments, the selection instruction comprises: a selection instruction for selecting at least one lyric; or a selection instruction to select the lyrics of a specific singer. Referring to FIG. 2, an exemplary user interface for selecting lyrics to be performed by a user, such as the song "Send other," the user may select the lyrics of the song desired to be performed according to the lyric selection; or according to the playing time selection of the song, acquiring lyrics in the time period based on the selected time period, and singing the lyrics played by the song in the selected time by the user; it is also possible to follow the singer's choice, such as choosing the lyrics a male or female singer sings, or the lyrics a singer in a band sings. In still other embodiments, referring to another exemplary user interface for selecting lyrics to be sung by a user as illustrated in fig. 3, the user may select to sung the next lyric to be sung while playing the song, which may be by touching a screen of the client device, or, when playing the next lyric, the user may start singing, which is selected as the lyrics to be sung by the user.

Dividing the playing time of the song based on the time information corresponding to the lyrics sung by the user, namely based on the playing time of the song file synchronized with the display time of the corresponding lyrics, wherein the playing time period corresponding to the lyrics sung by the user is taken as the first segment time, taking the song < Sendo > as an example, when the lyrics sung by the user are 'outside the pavilion', 'at the side of the ancient street' and 'after-wind-whistling willow flute sound residue', the playing time of the three lyrics in the song is divided into: 25s-26s, 27s-29s and 36s-42s as a first segment time, and the rest of the playing time of the song as a second segment time. Wherein the first segment time and the second segment time constitute the complete playing time of the song. It should be noted that the lyrics may be obtained based on an LRC lyric file, and the lyric display time and the corresponding song playing time are obtained through a time tag included in the LRC lyric file.

In some embodiments, referring to the schematic flow chart of the audio recording method shown in fig. 4, at step 202, the original audio corresponding to the first segment time is separated before the first segment time starts.

Specifically, before the lyrics corresponding to a first section of time begin to play, the original audio frequency of the playing time corresponding to the lyrics is separated, so that only the corresponding accompaniment audio frequency is played in the first section of time, and similarly, the same steps are performed before the lyrics corresponding to another first section of time begin to play. And in the second subsection time, playing the corresponding accompaniment audio and the original singing audio, and understanding that the complete audio of the time is played in the second subsection time without separating the original singing audio and the accompaniment audio. In the embodiment shown in fig. 4, step 201, step 203, and step 204 are respectively the same as steps 101 to 103 in the embodiment shown in fig. 1, and are not repeated here.

In further embodiments, referring to the schematic flow chart of the audio recording method shown in fig. 5, at step 301, before playing a song file, the accompaniment audio and the original audio of the song file are separated.

Specifically, the original audio and the accompaniment audio of the song file may be separated before the song is played in the recording mode. Only corresponding accompaniment audio is played in the first segment time, and corresponding separated accompaniment audio and original singing audio are played in the second segment time. In this way, it is not necessary to perform the separation process once before the start of each first divisional time, and the efficiency of the separation process can be improved. In the embodiment shown in fig. 5, steps 302 to 304 are respectively the same as steps 101 to 103 in the embodiment shown in fig. 1, and are not repeated here.

According to the method for separating the original singing audio and the accompaniment audio of the mixed audio file in the embodiment, the accompaniment and singer voice can be played instead of the audio file divided according to the left and right sound channels, the corresponding accompaniment file does not need to be searched similarly from the cloud, the problem that when the song file needing to be played is the mixed audio file, the corresponding accompaniment audio cannot be played in a certain section of time, the corresponding accompaniment audio and the original singing audio are played in another section of time, and the obtained user audio is synthesized to obtain the recorded file is avoided, so that the requirement of the user on chorus with the original singing can be met, and the experience of the user on listening to the song and singing with the K song and sharing is improved.

In some embodiments, the aforementioned separation step employs a fourier transform method and/or a multi-channel separation method. The separation processing can be performed on a computer or a vehicle-mounted terminal or other equipment, and can also be transmitted to the terminal equipment after corresponding cloud processing. When the song is the accompaniment audio with obviously different intensities in different sound channels, and the original singing audio with similar intensities in different sound channels, a multichannel separation method can be adopted. Specifically, in the stereo mode, the left and right channel information are subtracted (i.e., one of the channels is inverted and then superimposed). An audio part with the original singing removed can be obtained; under the surround mode, can directly reject the central channel in order to obtain stereo accompaniment audio, get the central channel alone and can obtain the original audio of singing. When a song does not fit into a multichannel separation method, such as a mono song, a fourier transform method may be used. Specifically, fourier transform is performed on the mixed audio to obtain a spectrogram of the mixed audio, the spectrogram is input to the neural network to obtain a spectrogram corresponding to the accompaniment audio and a spectrogram corresponding to the original singing audio, and Fourier inverse transform is performed on the spectrograms corresponding to the accompaniment audio and the original singing audio respectively according to the spectrogram of the mixed audio to obtain the accompaniment audio and the original singing audio.

At step 102, user audio is captured and simultaneously played.

Specifically, audio data of the user may be collected through a microphone. In some embodiments, audio data that the user sings is captured, recorded and played out at the same time during the first segment, and the captured audio data is not recorded but played out during the second segment. Therefore, irrelevant audio data can be prevented from being acquired and recorded in the second segment time, and the quality of the subsequently synthesized recording file is ensured. It should be understood that the time interval for acquiring the audio data sung by the user may be slightly wider than the time interval of the first divisional time, considering that there is a little time deviation when the user sung the corresponding lyrics. Therefore, different singing levels of different users can be taken care of, and the experience of listening to songs, singing K and sharing by the users is improved.

In some embodiments, the user audio and the corresponding accompaniment audio acquired at the first segment time are mixed to obtain an audio file including the user audio and the accompaniment audio corresponding to the first segment time.

At step 103, the accompaniment audio, the user audio and a portion of the original singing audio are synthesized to obtain a recording file.

In some embodiments, the user audio obtained and recorded in the first segment time, the original audio corresponding to the second segment time, and the accompaniment audio in the first segment time and the second segment time are synthesized to obtain the recording file.

In some embodiments, the second segment time plays the corresponding separated accompaniment audio and original song audio, and the accompaniment audio and the original song audio need to be mixed first to obtain an audio file including the accompaniment audio and the original song audio corresponding to the second segment time, and then the accompaniment audio corresponding to the first segment time is synthesized with the user audio.

In some embodiments, after synthesizing the first audio accompaniment audio, the user audio and the portion of the second audio original audio to obtain the recorded file, the method further includes: and uploading the recording file to the cloud. And uploading the recorded files of the user and the star chorus to a network so as to be conveniently shared with other people.
