Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

The embodiment of the application provides an audio playing method which can be realized by a terminal. The terminal can be a mobile phone, a tablet personal computer and other devices. A recording application for song recording may be installed in the terminal. The recording application may be a stand-alone application or an application plug-in. The recording application program can be a comprehensive application program with various functions, such as song recording function, music playing function, live broadcasting function and the like, or can be an application program with single function and only has song recording function.

FIG. 1 is a schematic diagram of an implementation environment provided by an embodiment of the present application. Referring to fig. 1, the above terminal may establish a connection with a bluetooth playing device, where the bluetooth playing device may be a bluetooth headset, a bluetooth speaker, a television with a bluetooth function, or the like. In the process of recording songs by using the recording application program, the terminal can send accompaniment of the songs and voice when the user sings to the Bluetooth playing device, and the Bluetooth playing device plays the accompaniment and the voice.

Fig. 2 is a flowchart of audio playing according to an embodiment of the present application. Referring to fig. 2, this embodiment may include the steps of:

step 201, detecting a recording trigger event for a target song.

In practice, when a user wants to record a song, he or she can open a recording application installed in the terminal and enter a song selection interface.

As shown in fig. 3, a recommended song list and a song search field may be displayed in the song selection interface, and the user may select a target song desired to be recorded through the recommended song list, and may also search for and select a target song desired to be recorded through the song search field. After recommending song information for each song in the song list, an accompaniment audio acquisition option, i.e., the option of the word "K song" in fig. 3, may be displayed. The user can click on the accompaniment audio acquisition instruction of the target song triggered by the accompaniment audio acquisition option corresponding to the target song, after receiving the accompaniment audio acquisition instruction of the target song triggered by the user, the terminal can search whether the accompaniment audio of the target song is stored locally or not preferentially, and if not, the accompaniment audio of the target song is downloaded to a background server of the record application program.

The recording application may then jump to a recording preparation interface. As shown in fig. 4, in the recording preparation interface, there may be displayed a recording start option, i.e., an option of "start K song" word in fig. 4. When the record preparation interface is displayed, a record triggering event can be detected. Here, the recording triggering event may be a touch operation of the user on the recording starting option, where the touch operation may be clicking, long pressing, double clicking, etc., and when the user performs the touch operation on the recording starting option, the terminal may detect the touch operation. Or the recording trigger event can also display preset time length for the recording preparation interface, namely, after the recording application program jumps to the recording preparation interface, the recording preparation interface displays the preset time length. For example, the preset duration may be 5 seconds.

Step 202, transmitting the accompaniment audio of the target song to the connected Bluetooth playing device, so that the connected Bluetooth playing device plays the accompaniment audio of the target song.

In an implementation, after detecting a recording trigger event for a target song, the terminal may then encode the accompaniment audio using the bluetooth decoder of the system and send the accompaniment audio to the connected bluetooth device. The connected Bluetooth playing device decodes and plays the accompaniment audio after receiving the accompaniment audio. In addition, after detecting the recording trigger event of the target song, the recording application program can jump to a singing interface of the target song, and lyrics of the target song can be displayed in the singing interface, so that a user can browse the lyrics to record the song.

In one possible implementation, when entering the singing interface of the target song, the terminal may not be connected to the bluetooth playing device, and then it may be checked whether the accompaniment audio is already connected to the bluetooth playing device before sending the accompaniment audio to the bluetooth playing device, and accordingly, the processing may be as follows: when the situation that the Bluetooth playing device is not connected with the Bluetooth playing device is detected, playing the accompaniment audio through a loudspeaker of the terminal, and displaying Bluetooth connection prompt information on a singing interface of a target song; and when the connection with the Bluetooth playing device is detected, canceling displaying Bluetooth connection prompt information in the singing interface.

In an implementation, if the terminal detects that the terminal is not connected with the Bluetooth playing device, the accompaniment audio of the target song is played through a loudspeaker of the terminal, and Bluetooth connection prompt information can be displayed in the singing interface. In the singing interface shown in fig. 5, the "trial connection bluetooth device K song" in the right window is the bluetooth connection prompt message. In addition, besides the Bluetooth connection prompt information, a Bluetooth connection prompt option can be displayed. After the user selects the dental connection prompting option, bluetooth connection recommendation information as shown in fig. 6 can be displayed to recommend the user to use the bluetooth playing device for song recording.

In the process of playing accompaniment audio through a loudspeaker of the terminal, if a user is connected with Bluetooth playing equipment, the terminal detects that the user is connected with the Bluetooth playing equipment, and Bluetooth connection prompt information is canceled from being displayed in a singing interface. Meanwhile, the Bluetooth connection prompting option mentioned above can be removed and is not displayed any more.

In addition, in the process of connecting the Bluetooth playing device, the terminal can stop playing the accompaniment audio, display a continuous record option in the singing interface, and after the Bluetooth playing device is connected, the user can click the continuous record option to restart record. And the terminal sends the first accompaniment audio which is not played to the Bluetooth playing equipment for playing.

Step 203, acquiring voice audio, and sending the voice audio to the connected bluetooth playing device, so that the connected bluetooth playing device plays the voice audio in the process of playing the accompaniment audio of the target song.

In implementation, the user can sing the target song while listening to the accompaniment audio, and the terminal can collect the voice audio of the user when singing through the microphone. And the collected voice audio is encoded by a Bluetooth decoder of the system and then sent to the connected Bluetooth playing equipment. After receiving the voice audio, the Bluetooth playing device decodes the voice audio and plays the voice audio in the process of playing the accompaniment audio.

In one possible implementation manner, the user may turn on or off the function of the terminal for sending the voice audio to the connected bluetooth playing device, and the corresponding processing may be as follows: displaying a Bluetooth playing setting option in a singing interface, and displaying a Bluetooth playing setting window when receiving an opening instruction of the Bluetooth playing setting option, wherein the Bluetooth playing setting window comprises a hearing-back function option; and stopping sending the voice audio to the connected Bluetooth playing equipment when receiving a closing instruction of the hearing-back function option.

In an implementation, in a case where the terminal is already connected to the bluetooth playing device, a bluetooth playing setting option may also be displayed in the singing interface of the target song. Here, if the terminal has connected to the bluetooth playback device before entering the singing interface, a bluetooth playback setting option may be displayed in the singing interface when entering the singing interface. If the Bluetooth playing device is connected after entering the singing interface, after the Bluetooth playing device is successfully connected, the Bluetooth playing setting option can be displayed in the singing interface while the Bluetooth connection prompting information and the Bluetooth connection prompting option are canceled to be displayed. As shown in fig. 7, the bluetooth-shaped option on the right side of the singing interface is the bluetooth play setting option. After the user selects the Bluetooth playing setting option, a Bluetooth playing setting window can be popped up, a hearing-back function option can be displayed in the Bluetooth playing setting window, and the user can close the hearing-back function by clicking the hearing-back function option, namely, the terminal does not send human voice audio to the Bluetooth playing equipment any more. Of course, in the case where the return function is turned off, the user can turn on the return function by clicking the return function option as well. The present embodiment shows only one example of controlling the hearing-back function, and does not represent a limitation on the manner in which the hearing-back function is controlled.

In addition, the user can adjust the volume of the voice audio, and the corresponding processing can be as follows: and the Bluetooth playing setting window also comprises a voice volume adjusting control, and the voice volume adjusting control is used for receiving a voice volume adjusting instruction triggered by the voice volume adjusting control and adjusting the voice volume of voice audio.

As shown in fig. 8, a voice volume adjustment control may also be provided in the bluetooth play setting window, and the user may slide a volume bar in the voice volume adjustment control to trigger a voice volume adjustment instruction to adjust the volume of the voice audio. A user sliding right may be to increase the volume and sliding left may be to decrease the volume. Of course, the volume adjustment logic of the voice audio may also be configured to slide left to increase the volume and slide right to decrease the volume for the user, which is not limited by the embodiment of the present application. After the user adjusts the volume of the voice audio through the voice volume adjusting control, the subsequent terminal obtains the volume of the voice audio sent to the Bluetooth playing device and correspondingly adjusts the volume of the voice audio. The present embodiment shows only one example of triggering the voice volume adjustment command, and does not represent a limitation on the manner in which the voice volume adjustment command is triggered.

In addition, the user can also adjust the volume of the accompaniment audio, and the corresponding processing can be as follows: the bluetooth playing setting window may further include an accompaniment volume adjustment control, and the accompaniment volume adjustment control is used for receiving an accompaniment volume adjustment instruction triggered by the accompaniment volume adjustment control and adjusting the volume of the second accompaniment audio, where the second accompaniment audio is a part of the accompaniment audio of the target song that is not played when the accompaniment volume adjustment instruction is received.

As shown in fig. 9, an accompaniment volume adjustment control may also be provided in the bluetooth play setup window, and the user may slide a volume bar in the accompaniment volume adjustment control to trigger an accompaniment volume adjustment instruction to adjust the volume of the accompaniment audio. A user sliding right may be to increase the volume and sliding left may be to decrease the volume. Of course, the volume adjustment logic of the accompaniment audio may also be configured to slide left to increase the volume and slide right to decrease the volume for the user, which is not limited by the embodiment of the present application. After the user adjusts the volume of the accompaniment audio through the accompaniment volume adjustment control, the subsequent terminal sends the volume of the accompaniment audio to the Bluetooth playing device to correspondingly adjust. The present embodiment shows only one example of triggering the accompaniment volume adjustment command, and does not represent a limitation on the manner in which the accompaniment volume adjustment command is triggered.

In one possible implementation, to reduce the latency of the hearing return, the process may be as follows: and calling a preset Bluetooth decoder according to a preset period, and correspondingly, the terminal can encode accompaniment audio and voice audio through the preset Bluetooth decoder and then send the accompaniment audio and the voice audio to the Bluetooth playing equipment.

In practice, when the terminal transmits the voice audio and the accompaniment audio to the bluetooth playing device, it is necessary to encode it by using a bluetooth decoder of the system. In the embodiment of the application, a preset Bluetooth decoder with relatively low time delay can be selected to encode the voice audio and the accompaniment audio, such as Apt-X (Audio Processing Technology-X ). In order to prevent the system from reverting the called preset bluetooth decoder to the bluetooth decoder which is automatically matched with the system, the preset bluetooth decoder can be called according to a preset period. For example, the preset period may be 3 seconds.

According to the embodiment of the application, after detecting the record triggering event of the target song, the terminal can send the accompaniment audio of the target song to the connected Bluetooth equipment. The terminal can also acquire the voice audio of the user during singing and send the voice audio to the Bluetooth playing device. The bluetooth playing device may also play the vocal audio in the course of playing the accompaniment audio of the target song. In the recording process, the user can timely hear whether the song of the user is running or not through the Bluetooth playing device or not reaching the expectation, and the user does not need to wait until the recording of the whole song is completed, and then play back the song again to check whether the song is running or not. Therefore, if running tone is found in the recording process or the expected running tone is not reached, the recording can be stopped in time and restarted, the recording time of the user is saved, and the song recording efficiency is higher.
