The embodiment of the invention provides a method for acquiring music information, and aims to more clearly describe the scheme of the invention. Some of the knowledge involved in the method for acquiring music information provided by the embodiments of the present application will be described below.
1. Audio/video remote control profile (AVRCP): AVRCP defines the features and procedures by which bluetooth devices communicate with audio/video control functions. AVRCP is designed to provide a standard interface for controlling TV, Hi-fi devices, etc. This profile is used to permit a single remote control device (or other device) to control the a/V devices that all users may access. Furthermore, AVRCP also defines how to control the characteristics of streaming media. Including pausing, stopping, starting playback, volume control, and other types of remote control operations.
2. Bluetooth audio distribution profile (A2 DP): a2DP specifies protocol stack software and a method of use for transmitting high-quality music file data using a bluetooth asynchronous transmission channel method, based on which high-quality music can be transmitted by bluetooth transmission, for example, music can be listened to using a stereo bluetooth headset or a bluetooth sound device.
3. Pulse Code Modulation (PCM): PCM is a digital signal generated by sampling, quantizing, and encoding a continuously varying analog signal. The PCM has the advantages of good sound quality and large volume. PCM may provide private line services for digital data at rates from 2M to 155M for users, as well as other services for voice, image transfer, distance learning, and the like.
AudioTrack: AudioTrack is the framework used by the android system to play audio, capable of playing a PCM stream that has been decoded for playback of the PCM audio stream.
5. Envelope information of song: the jacket information of the song at least comprises album cover information of the song, and may also comprise one or more combinations of information such as song name, singer name, lyrics and singer portrayal.
6. Object exchange protocol (OBEX): the object exchange protocol has a core position in software, and is used for file transmission and infrared communication synchronization.
7. Basic Imaging Profiling (BIP): the basic imaging specification protocol is included in the OBEX protocol, which is used to specify the transfer of images between different devices.
With the development of technology, people tend to control the operation of the vehicle-mounted terminal through an intelligent terminal such as a mobile phone or a tablet by using a bluetooth technology more and more in the driving process of an automobile. For example, during driving, people often connect a mobile phone with a vehicle-mounted terminal through bluetooth. Therefore, the vehicle-mounted terminal can be conveniently and quickly controlled to play music through the mobile phone without directly operating the vehicle-mounted terminal. However, when a song is downloaded, because part of the song information is missing, there may be no envelope information of the song in the memory of the mobile phone, or the bluetooth version of one of the mobile phone and the vehicle-mounted terminal does not support sending or receiving the envelope information of the song, so that when the mobile phone controls the vehicle-mounted terminal to play music through bluetooth, the vehicle-mounted terminal may not be able to directly acquire the envelope information of the song from the mobile phone, which affects user experience.
In the bluetooth data sent by the mobile phone to the vehicle-mounted terminal, text information such as a song name and a singer name of a song or lyrics may be included, but information included in jacket information of the song such as album cover of the similar song, singer's photo and the like is not included. For the problem, a music facilitator interface may be invoked to search for envelope information of a song based on the artist name and song name of the song contained in the bluetooth data. Therefore, when the mobile phone controls the vehicle-mounted terminal to play the song, the vehicle-mounted terminal can display the envelope information of the song. However, due to the limitation of the bluetooth protocol, the same field is used for the text information such as the name of the song, the name of the singer, and the lyrics in the bluetooth data during the bluetooth transmission, and the field has a length limitation, so that the name of the singer and the name of the song are not likely to exist in the text information of the bluetooth data, for example, the field may only have the lyrics, and the name of the singer and the name of the song are not present; alternatively, for example, the field may have only the name of the singer, but not the name of the song and the lyrics. When the song is searched, the text information in the default field of the music service provider is the song name and the singer name of the song, when the text information in the field is the song lyrics actually, or only the song name or the singer name exists in the text information, the music service provider may not successfully search the envelope information of the song, and the vehicle-mounted terminal may not successfully acquire and present the envelope information of the song.
In view of the disadvantages of the method, an embodiment of the present application provides a method for acquiring music information, where the method acquires a song title and a singer title of a song corresponding to an audio stream by capturing audio stream data in bluetooth data and identifying the audio stream data, and then acquires jacket information of the song based on the song title and the singer title.
Next, a flowchart of a method for acquiring music information according to an embodiment of the present application will be described, please refer to fig. 1. As shown in fig. 1, the method comprises the steps of:
101. and acquiring Bluetooth data, wherein the Bluetooth data comprises audio stream data of the target song.
The second terminal is connected with the first terminal through Bluetooth, and the Bluetooth data is sent by the first terminal and received by the second terminal. The first terminal can be a mobile phone, a tablet, a wearable device, a smart sound box, a vehicle-mounted terminal or other terminal devices with music playing and Bluetooth transmission functions, and the second terminal can be a mobile phone, a tablet, a smart sound box, a wearable device, a vehicle-mounted terminal and other terminal devices with music playing, Bluetooth transmission and visualization functions.
In an optional implementation manner, the first terminal may be a smart speaker, a vehicle-mounted terminal, or other terminal devices having music playing and bluetooth transmission functions, and the second terminal may be a mobile phone, a tablet, a wearable device, or other terminal devices having music playing, bluetooth transmission, and visualization functions. Furthermore, the first terminal and the second terminal may both be mobile phones with music playing and bluetooth transmission functions. That is to say, the first terminal and the second terminal may be a combination of a mobile phone and a vehicle machine, a vehicle machine and a mobile phone, a mobile phone and a mobile phone, and the like, and the embodiment of the present application is not limited herein.
And when the first terminal plays the target song, the Bluetooth data is sent to the second terminal through Bluetooth, and the second terminal synchronously plays the target song played on the first terminal. The bluetooth data comprises binary stream data characterizing an audio clip in the target song, i.e., the audio stream data.
102. And extracting the audio stream data in the Bluetooth data to obtain an audio file.
And the audio stream data is binary stream data which is transmitted by the target song through Bluetooth and represents an audio fragment in the target song. And after receiving the Bluetooth data sent by the first terminal, the second terminal synchronously plays the target song played by the first terminal. At this point, the audio stream data will be written into the receiver of audio channel A2DP of bluetooth type in AudioTrack. In the process, the audio stream data is recorded to obtain a corresponding recording file, and the recording file is stored in a preset format (such as a PCM format) to obtain the audio file. It should be understood that when the audio file is subsequently identified by calling the interface of the music service provider (e.g., the dog music), the preset format will be adjusted according to the specific requirements of the music service provider (e.g., PCM format) for identifying the audio recording file when the audio recording file is saved, because different music service providers have different requirements for the file formats of the identified songs.
103. And acquiring the song name and the singer name of the target song based on the audio file.
After the audio file with the specific preset format is obtained, the second terminal obtains the song name and the singer name of the target song based on the audio file.
Specifically, the second terminal transmits the audio file to a music facilitator providing a song recognition function such as cool-me music, QQ music, and the like, and simultaneously transmits a recognition request for recognizing the audio file to the music facilitator. And after receiving the audio file and the identification request, the music service provider identifies and compares the audio file with the music data in the database, and returns the song name and the singer name of the song with the highest similarity rate with the audio file to the second terminal to serve as the song name and the singer name of the target song.
104. And acquiring the envelope information of the target song based on the song name and the singer name.
And after receiving the singer name and the song name returned by the music service provider, the second terminal calls an interface of the music service provider to search the song name and the singer name so as to obtain the envelope information of the target song. Further, after searching the jacket information of the target song, the second terminal receives the resource address of the jacket information returned by the music service provider, and displays the jacket information on the display screen of the second terminal based on the resource address.
The embodiment of the application acquires the song name and the singer name of the corresponding song of the audio stream by grabbing the audio stream data in the Bluetooth data and identifying the audio stream data, and then the defect that the envelope information of the song cannot be acquired due to the missing of the text information of the song in the Bluetooth data is overcome, the efficiency of synchronizing the music information between different terminals is improved, the user interface at the end of the vehicle is more attractive in display, and the vehicle owner can acquire better use experience.
It should be understood that the bluetooth data in the method may contain textual information such as the name of the song, the name of the singer, and the lyrics of the song, in addition to the audio stream data of the target song, and in some embodiments may even include envelope information for the target song. In this case, the second terminal receiving the bluetooth data can more easily acquire the envelope information of the target song based on the text information. Therefore, in some embodiments, the second terminal may determine data in the bluetooth data to avoid waste of system resources due to unnecessary operations. Therefore, on the basis of the method described in fig. 1, the present embodiment provides a flowchart of another method for obtaining music information, please refer to fig. 2.
Fig. 2 is a flowchart of another method for acquiring music information according to an embodiment of the present application. As shown in fig. 2, the method comprises the steps of:
201. and receiving Bluetooth data.
The second terminal is connected with the first terminal through Bluetooth, and the Bluetooth data is sent by the first terminal and received by the second terminal. The first terminal can be a mobile phone, a tablet, a wearable device, a smart sound box, a vehicle-mounted terminal or other terminal devices with music playing and Bluetooth transmission functions, and the second terminal can be a mobile phone, a tablet, a smart sound box, a wearable device, a vehicle-mounted terminal and other terminal devices with music playing, Bluetooth transmission and visualization functions.
In an optional implementation manner, the first terminal may be a smart speaker, a vehicle-mounted terminal, or other terminal devices having music playing and bluetooth transmission functions, and the second terminal may be a mobile phone, a tablet wearable device, or other terminal devices having music playing, bluetooth transmission, and visualization functions. Furthermore, the first terminal and the second terminal can be both mobile phones with music playing and bluetooth transmission functions. That is to say, the first terminal and the second terminal may be a combination of a mobile phone and a vehicle machine, a vehicle machine and a mobile phone, a mobile phone and a mobile phone, and the like, and the embodiment of the present application is not limited herein.
And when the first terminal plays the target song, the Bluetooth data is sent to the second terminal through Bluetooth, and the second terminal synchronously plays the target song played on the first terminal. The Bluetooth data comprises binary stream data representing an audio clip in the target song, namely the audio stream data; in addition, the bluetooth data may also include one or more combinations of information such as song name, singer name, lyrics, singer photo, and the like of the target song; in some embodiments, the bluetooth data may include envelope information for the target song.
202. And judging whether the Bluetooth data contains the envelope information of the target song.
After receiving the bluetooth data, the second terminal first determines whether the envelope information of the target song exists in the bluetooth data.
It should be understood that, in some embodiments, the first terminal already stores the envelope information of the target song, and after the first terminal and the second terminal are in bluetooth connection, if the bluetooth protocol (such as AVRCP1.6) used by the bluetooth versions of the two terminals supports transmission of the envelope information, the first terminal will send the envelope information to the second terminal based on the BIP protocol in the OBEX protocol. After receiving the bluetooth data, the second terminal acquires the envelope information in the bluetooth data by adapting to the protocol described by the BIP, and performs step 208, that is, displays the envelope information on a display screen.
In some embodiments, the envelope information of the target song may not be stored or successfully acquired in the first terminal; or the bluetooth version of one of the first terminal and the second terminal does not support transmission of the envelope information. At this time, the first terminal cannot send the envelope information of the song to the second terminal, and the envelope information of the target song does not exist in the bluetooth data. In this case, the second terminal will perform step 203.
203. And acquiring the envelope information of the target song based on the text information in the Bluetooth data.
And under the condition that the envelope information of the target song does not exist in the Bluetooth data, the second terminal cannot directly acquire the envelope information of the target song from the Bluetooth data. At this time, the second terminal acquires the envelope information of the target song through the text information in the bluetooth data.
204. And judging whether the envelope information of the target song is acquired or not.
The second terminal calls an interface of a music service provider according to the text information, and the music service provider searches envelope information based on the text information and judges whether an envelope is searched according to a specific envelope field in the searched and returned data. If the field content is a resource address (URL) of the envelope information and the resource address is unique, it is determined that the envelope information is successfully acquired; if the field is empty or the resource address is not unique, it is determined that the envelope information was not successfully acquired.
In some embodiments, the textual information may be a song name of the song and a singer name due to a relationship between a music player used by the first terminal to play the target song and a bluetooth compliant protocol; alternatively, the textual information may be lyrics of a song. Specifically, in the process of transmitting the bluetooth data to the second terminal by the first terminal through bluetooth, due to the limitation of the bluetooth protocol, the fields used by the song lyrics, the song name and the singer name in the transmission process are the same, but the fields can only accommodate the song name and the singer name of the target song or only accommodate the song lyrics. In other words, in a bluetooth transmission, only the artist name and song name of the target song, or only the lyrics of the target song, will be present in the text message. Due to the adaptation between the bluetooth protocol and the music player in the first terminal playing the target song, the information type in the text information differs for different music players. For example, it is assumed that two different music players (hereinafter referred to as player X and player Y) are installed on the first terminal, and when the first terminal plays the target music using player X, the bluetooth data sent to the second terminal may include a song name and a singer name of the target song, but does not include lyrics; however, if the first terminal uses player Y to play the target music, the bluetooth data sent to the second terminal may include lyrics of the target song, but not a song name and a singer name. In some embodiments, there is a case where the information is empty in the field a and the field B; that is, there may be a case where the field a is the name of a song, no text information exists in the field B, no information exists in the field a, the name of a singer of the song exists in the field B, or no text information exists in the field a and the field B, which is related to the type of player playing the song by different music service providers.
It should be appreciated that when a music facilitator interface is invoked to search for textual information retrieved from the bluetooth data, a music facilitator, such as the cool dog, cool me, defaults to the textual information as the song name and artist name of the song. When the text information in the bluetooth data includes the song name and the singer name of the target song, the fields can be regarded as two fields (hereinafter referred to as field a and field B), the song name of the target song is in field a, and the singer name of the target song is in field B. When the second terminal calls a music service provider interface to search the text information, the music service provider identifies the song name and the singer name in the field A and the field B, searches the envelope information of the target song in the database, and returns the resource address of the envelope information to the second terminal when the envelope information is successfully searched. After receiving the resource address of the jacket information returned by the music service provider, the second terminal directly performs step 208, that is, the jacket information corresponding to the resource address is displayed on a screen; when the text information in the bluetooth data contains lyrics of the target song, the lyric fragments stored in the field a and the field B are the lyric fragments of the target song, when the second terminal calls a music facilitator interface to search the text information, because the music facilitator cannot distinguish and identify the song name, the singer name and the lyrics from the code level, the music facilitator defaults that the text information in the field a and the field B is still the song name and the singer name of the target song, and searches the envelope information of the target song in the database, but because the text information in the field a and the field B is the lyrics of the target song, the database does not have envelope information matched with the lyrics, and the envelope information corresponding to the target song cannot be successfully searched naturally, the second terminal cannot acquire and display the envelope information of the target song; or when the field a is the song name of the song and the field B is empty, the same song may have different versions that the singer sings, or different songs may have the same song name, so the music service provider will provide a plurality of envelope information, the music service provider may return a plurality of resource addresses, and the second terminal still cannot accurately obtain the envelope information of the target song. That is, in the case where one of the singer name and the song name is absent from the text information included in the fields a and B, the music service provider cannot accurately search the jacket information of the target song. In case the second terminal does not successfully acquire the envelope information or the acquired envelope information is not unique, the second terminal will continue to perform step 205.
205. And recording audio stream data in the Bluetooth data to obtain an audio file.
And in the case that the second terminal fails to acquire the envelope information of the target song directly through the text information in the Bluetooth data, the second terminal acquires the envelope information of the target song through the audio stream data of the target song in the Bluetooth data.
And the audio stream data is binary stream data which is transmitted by the target song through Bluetooth and represents an audio fragment in the target song. And after the second terminal receives the Bluetooth data sent by the first terminal, the target song which is played by the first terminal is played synchronously. At this point, the audio stream data will be written into the receiver of audio channel A2DP of bluetooth type in AudioTrack. The process is equivalent to recording the audio stream data to obtain a recording file, and storing the recording file into a preset format (such as a PCM format) to obtain the audio file. It should be understood that when the audio file is subsequently identified by calling the interface of the music service provider (e.g., the dog music), the preset format will be adjusted according to the specific requirements of the music service provider (e.g., PCM format) for identifying the audio recording file when the audio recording file is saved, because different music service providers have different requirements for the file formats of the identified songs.
206. And acquiring the song name and the singer name of the target song based on the audio file.
After the audio file with the specific preset format is obtained, the second terminal obtains the song name and the singer name of the target song obtained after the audio file is identified.
Specifically, the second terminal transmits the audio file to a music facilitator providing a song recognition function such as cool-me music, QQ music, and the like, and simultaneously transmits a recognition request for recognizing the audio file to the music facilitator. And after receiving the audio file and the identification request, the music service provider identifies and compares the audio file with the music data in the database, and returns the song name and the singer name of the song with the highest similarity rate with the audio file as the song name and the singer name of the target song.
207. And acquiring the envelope information of the target song based on the song name and the singer name.
The second terminal calls the music service provider interface to search the song name and the singer name of the song returned by the music service provider, the music service provider searches the envelope information of the target song in the database, and when the envelope information is successfully searched, the envelope information is returned to the second terminal. When the second terminal receives the jacket information returned by the music service provider, step 208 is directly performed, that is, the jacket information is displayed on a screen.
208. Displaying the envelope information.
It should be understood that the step 208 is further performed selectively after acquiring the envelope information, and there are three ways for acquiring the envelope information, one way is in a case that the envelope information of the target song exists in the bluetooth data, the second terminal will acquire the envelope information of the target song directly from the bluetooth data (see the description of the step 202 in the method); when the second approach is that the text information in the bluetooth data includes the song name and the singer name of the target song, the second terminal calls an interface of a music service provider to directly search the song name and the singer name, and obtains the envelope information of the target song (see the description of step 204 in the method); and under the condition that the envelope information of the target song is not successfully acquired by the first route and the second route, acquiring the envelope information of the target song through a third route, namely, the second terminal acquires an audio file in a specific format by recording audio stream data representing an audio clip in the target song in the bluetooth data, identifies the audio file by calling an interface of a music service provider, acquires a song name and a singer name of the target song, and calls the interface of the music service provider again to search the song name and the singer name to acquire the envelope information of the target song (see the description of the step 205, the step 206 and the step 207 in the method).
It should be understood that if the second terminal has already acquired the envelope information of the target song in a certain step as shown in fig. 2, the second terminal will directly perform step 208, and the rest of the steps that are not performed will not be performed. For example, in step 202, if the envelope information of the target song already exists in the bluetooth data, and actually the second terminal has already acquired the envelope information of the target song after performing step 203, the second terminal will not perform subsequent step 204, step 205, step 206, and step 207, but directly perform step 208, that is, display the envelope information, and the whole process is ended.
According to the embodiment of the application, while the defect that the envelope information of the song cannot be acquired due to the fact that the text information of the song in the Bluetooth data is lost is overcome, the text information in the Bluetooth data is further screened and monitored, the envelope information of the song is ensured to be acquired through audio stream data under the condition that the text information is invalid, waste of system resources is avoided, the efficiency of music information synchronization among different terminals is further improved, and a vehicle owner can obtain better use experience.
