In an exemplary embodiment of a music broadcasting method of the present application, which is implemented as a computer program running on a server, a program interface for external call is opened, which can be called by an application program of the server or a terminal device. Referring to fig. 2, in the exemplary embodiment, the method specifically includes the following steps:
Step S11, responding to a starting instruction of a live broadcast room anchor user, and controlling the anchor user to start audio data acquisition:
and the server responds to the starting instruction sent by the live broadcasting room anchor user and controls the anchor user to which the starting instruction belongs to start the audio data acquisition.
The server acquires the audio data of the live broadcasting room of the anchor user in real time through a communication link established by the terminal equipment of the anchor user to which the starting instruction belongs, and correspondingly, the server acquires the audio data of the live broadcasting user through a corresponding channel so as to filter the audio recorded by the anchor user through the audio input equipment of the terminal equipment and prevent the audio data acquired by the server from containing other unnecessary audio.
The audio data generally refers to audio data played by the terminal device of the anchor user to which the start instruction belongs through a corresponding control, and generally does not include audio data recorded by the anchor user through an audio input device of the terminal device, so that the server accurately generates rhythm data of the audio data for the audio data of the music being played by the anchor user.
In one embodiment, the server collects the audio data of the anchor user and also broadcasts the audio data to all audience users in the anchor user's living broadcast room so that the audience users play the audio data by calling the corresponding players.
In one embodiment, referring to fig. 3, the steps of the front-end implementation of the method for sending the start command to the anchor user to trigger the server to start collecting the audio data of the anchor user are as follows:
step S111, the live room is controlled to enter a target mode for representing the virtual trampoline activity:
after the live broadcast is started by the anchor user, a corresponding trigger event is generated through a corresponding control of the touch graphical user interface, so that a live broadcast room of the anchor user enters the target mode representing the virtual trampoline activity, and the starting instruction is generated.
Step S112, playing the music specified by the anchor user in the live broadcast room in response to the start instruction of the anchor user:
and the terminal equipment of the anchor user responds to a starting instruction generated by the anchor user through a triggering event, and triggers the playing of the music appointed by the anchor user in the live broadcasting room.
The host user can select the appointed music through the corresponding control in the graphical user interface of the live broadcasting room, trigger the generation of the starting instruction and trigger the playing of the music in the live broadcasting room. The event of the music designated by the anchor user can be designed by a person skilled in the art according to the actual service scene, and the description is omitted.
Step S113, according to the setting state of a preset switch of the live broadcasting room, when the setting state represents the state allowing starting, starting audio data acquisition for the anchor user:
the method comprises the steps that a preset switch exists in a graphical user interface of a live broadcasting room of a host user, the current live broadcasting room is controlled to enter a target mode of the virtual trampoline activity through the setting state of the preset switch, and when the setting state of the preset switch is characterized as being started in advance, the host user sends a starting instruction to a server so as to trigger the server to start the collection implementation of audio data of the host user.
Step S12, acquiring live audio data of a terminal device of a live broadcasting user in a live broadcasting room in real time, and generating rhythm data according to the audio data, wherein the rhythm data comprises time information representing the occurrence of rhythm drum points and grade information representing the rhythm intensity of the occurrence of the rhythm drum points:
after the server responds to the starting instruction, the real-time acquisition of the audio data of the anchor user to which the starting instruction belongs is started, so that the server generates corresponding rhythm data containing time information representing the occurrence of rhythm drum points and grade information representing the rhythm intensity of the occurrence of the rhythm drum points according to the audio data acquired in real time.
The client of the anchor user collects the audio data of the anchor user in real time, and installs a preset sampling frequency for collection, wherein the unit of the preset sampling frequency is kilohertz (KHz), and the corresponding preset sampling frequency is generally 44100Khz, so that the sampled audio data is defined to be in a PCM format, and the subsequent implementation is convenient. The size of the preset acquisition frequency can be designed by a person skilled in the art according to an actual service scene, and is not repeated.
When the client collects audio data of a host user, rhythm drum points in the audio data are synchronously identified according to a preset threshold, the rhythm intensity is calculated according to the preset collection frequency and the rhythm drum points, and corresponding time information is generated by recording time of the rhythm intensity, so that a server collects the time information, and rhythm data corresponding to the audio data are generated according to the time information and the audio data.
The time information and the grade information in the rhythm data are in one-to-one correspondence, so that when the rhythm data output in the terminal equipment of the audience user in the live broadcasting room of the anchor user and the anchor user are controlled, the grade information in the rhythm data and the music played in the live broadcasting room realize the effect of synchronous output.
In one embodiment, referring to fig. 4, regarding a specific implementation of the server to generate corresponding rhythm data for the audio data, reference is made to the following specific implementation steps:
step S121, collecting the audio data in real time according to a preset sampling frequency:
the client acquires the audio data of the anchor user in real time according to a preset acquisition frequency, wherein the preset acquisition frequency is generally set at 44100Khz so that the acquired audio data is in a PCM format.
Step S122, determining sampling intervals according to a preset time length, dividing each sampling interval into a plurality of sampling units in an average mode, wherein each sampling unit comprises a plurality of sampling point data, and calculating the statistical average value of each sampling unit based on the sampling point data:
the client determines sampling intervals of the audio data according to the preset duration, and averagely divides each sampling interval of the audio data into a plurality of sampling units, wherein each sampling unit comprises a plurality of sampling point data in unit time, so that the server calculates the statistical average value of each sampling unit based on the sampling point data.
Referring to fig. 5, the predetermined time period is generally set on the order of milliseconds so as to more precisely analyze the sampling point data of the audio data by dividing a plurality of the sampling intervals, and accordingly, the client equally divides each of the sampling intervals of the audio data into a plurality of the sampling units, and obtains a statistical average value of each of the sampling units by performing a statistical average calculation on the sampling point data included in the sampling units, for example, the predetermined time period is set to 500ms, and accordingly, the server may divide each of the sampling intervals of the audio data determined by the predetermined time period into 5 copies, that is, the sampling units include the sampling point data within 100 ms.
Step S123, in the sampling process, based on whether the statistical average value of each sampling unit is greater than a preset threshold value, to identify a rhythmic drum point of the audio data, if the statistical average value of each sampling unit does not exceed the preset threshold value, continuing to determine the next sampling unit:
the client calculates the statistical average value of the first acquisition unit in the sampling point data by adding all the sampling point data contained in the sampling units and locating the sampling point data, so that the client judges whether the statistical average value of the sampling units is larger than the preset threshold value, if the statistical average value of the sampling units is smaller than or equal to the preset threshold value, the client judges the next sampling unit of the acquisition units, and the client continuously judges until one statistical average value is larger than the preset threshold value in the sampling units contained in the audio data.
