Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic flowchart illustrating an audio stream processing method according to an embodiment of the present invention; fig. 2 is a schematic diagram of a flow of querying a volume parameter value of an audio stream processing method according to an embodiment of the present invention.
In a specific implementation manner of the present invention, an embodiment of the present invention provides an audio stream processing method, including:
step S11: acquiring N real-time audio streams, wherein N is a positive integer;
in this embodiment, first, a currently active real-time audio stream needs to be acquired, for example, for a mobile phone, a plurality of applications (for example, map navigation voice prompt, music playing of music software, prompt tone of communication software such as WeChat, and the like) may be in an active state at the same time, and may drive a speaker to make a sound, and at this time, all active audio streams (track audio tracks) in a mobile phone system may be found out in a traversal manner.
Step S12: searching a corresponding volume parameter value in the volume parameter packet according to the port identity information of the N real-time audio streams; the volume parameter packet comprises port identity information and a volume parameter value which have a corresponding relationship;
after the current N real-time audio streams are found, these audio streams need to be sounded by the same speaker, and thus, these audio streams need to be mixed to be able to drive the speaker. In the prior art, a uniform sound parameter is used to mix audio streams, but in the present application, there is a volume parameter packet in which volume parameter values corresponding to respective audio streams are stored, for example, if there are two tracks: the method comprises the steps of receiving a music audio stream and a navigation audio stream, wherein the music audio stream and the navigation audio stream are received by a user, and the navigation audio stream is received by the user. At this time, the volume parameter value corresponding to the music audio stream can be set to 60%, and the volume parameter value corresponding to the navigation audio stream can be set to 80%, so that when a user drives, the user can listen to music without obstructing clear listening to the navigation broadcast sound.
For the audio stream, the port identity information (PID, port ID) input by the audio stream can be determined, so that the corresponding volume parameter value can be found when the volume parameter value is needed, as long as the corresponding relationship between the port identity information and the volume parameter value is determined in the volume parameter packet.
Of course, the volume parameter value herein does not only refer to the volume, but also refers to the playing mode of the sound, for example, for the sound of the navigation broadcast, the parameter may be set as the parameter of the human voice mode, so that the signal of the human voice frequency band of the navigation broadcast may be enhanced.
It should be noted that, for the setting of the volume parameter packet, in a specific practice, the setting may be a data packet, which includes a group of port identity information and volume parameter values with a corresponding relationship; for example, for APP1, there is first port identity information and a first volume parameter value in the volume parameter packet, for APP2, there is second port identity information and a second volume parameter value in the volume parameter packet, and for APPn, there is nth port identity information and nth volume parameter value in the volume parameter packet. In practice, of course, a separate volume parameter packet may be set for each APP, for example, a first volume parameter packet is set for APP1, a second volume parameter packet is set for APP2, and an nth volume parameter packet is set for APPn.
That is to say, the volume parameter of each APP can be placed in a data packet, and can also be stored in a packet manner, accordingly, when searching, if the volume parameter packet is one, the volume parameters of all APPs are stored in the data packet, then the search can be directly performed in the volume parameter packet, if each APP has a corresponding volume parameter packet, then the corresponding volume parameter packet can be searched according to the corresponding name of the volume parameter packet, and the data in the volume parameter packet is read to perform subsequent mixing processing.
Step S13: and carrying out sound mixing processing on the N real-time audio streams according to the corresponding volume parameter values to obtain a synthesized audio stream.
After the volume parameter values corresponding to the real-time audio streams are found, the audio streams can be mixed, so that a synthesized audio stream is obtained. Specifically, if the volume parameter value refers to a volume value, N real-time audio streams may be multiplied by the corresponding volume parameter value, respectively, to obtain N weighted audio streams; the N weighted audio streams are summed to obtain a composite audio stream.
That is, the volume parameter values corresponding to the N real-time audio streams may be weighted and summed, and the obtained result is the synthesized audio stream. Outputting the synthesized audio stream to a hardware interface to drive an audio hardware utterance.
After the synthesized audio stream is obtained, the synthesized audio stream can be output to a hardware interface, so that the magnitude of the current flowing through the loudspeaker can be driven to change, and the loudspeaker can generate sound. When the method is applied to electronic equipment of an android system, the audio track data of the synthetic audio stream can be output to a hardware interface of an audio HAL layer to drive hardware to sound.
Further, in order to search for a corresponding volume parameter value in the volume parameter packet according to the port identity information of the N real-time audio streams, the following steps may be specifically performed:
step S21: analyzing the N real-time audio streams to obtain corresponding port identity information;
in practice, when an application program requests an audio focus, the corresponding relationship between the packet name of the application program, that is, the packet name of the application program and port identity information PID is written into a Native layer core system service audiomaker (abbreviated as AF) for managing an audio module in an android system, and when a PID member variable is added to an audio stream object Track in the AF, and the AF creates the audio stream object Track each time, the PID transmitted by the application program is stored in the member variable PID of the Track. So that corresponding port identity information is present in the real-time audio stream.
Step S22: and searching an application program package name corresponding to the port identity information in a volume parameter package according to the first corresponding relation.
Since the port identity information and the application package name have the first corresponding relationship, the corresponding application package name can be found in the AF. The application program package name corresponds to the corresponding application program, and the user realizes that the volume parameter value is already set in the application program, so that the application program package name corresponds to the volume parameter value.
Step S23: if the corresponding application program package name is found, searching a volume parameter value corresponding to the application program package name in a volume parameter package according to a second corresponding relation to obtain volume parameter values corresponding to the N real-time audio streams; if the corresponding application program package name cannot be found, using a default volume parameter value; the volume parameter packet comprises a first corresponding relation between the application program packet name and the port identity information and a second corresponding relation between the volume parameter value and the application program packet name.
Of course, in practice, not every application user has set a corresponding volume parameter value, and if no corresponding British two parameter value is found, a default volume parameter value may be used.
Specifically, the corresponding relationship between the application package name and the port identity information is a first corresponding relationship; the corresponding relation between the volume parameter value and the application program package name is a second corresponding relation; when storing the first corresponding relationship and the second corresponding relationship, the process of acquiring the first corresponding relationship may be as follows: when an application program system acquires an audio focus, storing a first corresponding relation between an application program package name corresponding to the application program system and port identity information into the volume parameter package; the second corresponding relation is obtained as follows: receiving a second corresponding relation between the volume parameter value set by the user and the name of the application program package; and storing the second correspondence to the volume parameter packet. Therefore, the first corresponding relation and the second corresponding relation in the volume parameter packet are obtained.
Of course, in order to implement the operation on the volume parameter packet, an adding, updating, moving, and querying port may be further provided, so that when one or more of an adding request, an updating request, a removing request, and a querying request for the volume parameter packet is received, a corresponding action may be performed to add, update, remove, and query a new volume parameter value corresponding relationship.
Referring to fig. 3, fig. 3 is a flow chart illustrating a power-on setting of a volume parameter packet of an audio stream processing method according to an embodiment of the present invention.
On the basis of the foregoing embodiment, in this embodiment, taking the android system as an example, since the volume set for the application program is written by a code during running, the volume set is only valid during running of the android device this time, in order to achieve the purpose of persistence, after the volume is set for the application, the package name/volume information is stored in a settingspovider (setting storage area) database, and after the android device is started up again, the volume of each application is read from the settingspovider database and written into AF.
Of course, in addition to the android system, the following steps may be performed in other operating systems, such as the iOS system:
step S31: saving the volume parameter packet to a setting storage area;
step S32: and when the computer is started, calling the volume parameter packet from the setting storage area to a preset storage position so as to mix sound.
That is to say, in the embodiment of the present application, when the device is powered off, the volume parameter packet is stored in the setting storage area, so that when the device is powered on, data is directly read from the setting storage area and the volume parameter packet is rewritten in the AF, thereby facilitating subsequent call of the volume parameter packet for audio mixing processing.
Referring to fig. 4, fig. 4 is a flowchart of an intelligent vehicle-mounted terminal of an audio stream processing method according to an embodiment of the present invention.
In practice, it is often the case that a user listens to music and listens to a navigation broadcast while driving. Therefore to this condition, can be specifically for navigation broadcast audio stream, music broadcast audio stream with N real-time audio stream, be applicable to the driving in-process, specific audio stream processing step is as follows:
step S41: acquiring currently active navigation broadcast audio streams and music play audio streams;
step S42: searching a corresponding volume parameter value in a volume parameter packet according to the port identity information of the navigation broadcast audio stream and the music play audio stream; the volume parameter packet comprises port identity information and a volume parameter value which have a corresponding relationship, and the volume parameter value of the navigation broadcast audio stream is greater than the volume parameter value of the music play audio stream;
step S43: and carrying out sound mixing processing on the navigation broadcast audio stream and the music play audio stream according to the corresponding volume parameter values to obtain a synthesized audio stream.
For specific details, reference may be made to the foregoing embodiment, and in this embodiment, the data processing is performed on the real-time audio stream, specifically, the navigation broadcast audio stream and the music broadcast audio stream.
Compared with the method for processing the audio stream, which uses the same volume parameter value intelligently for each audio stream in the prior art, the method for processing the audio stream provided by the embodiment of the invention has the advantages that the volume parameter value of each audio stream can be specifically set, so that a user can set a larger volume parameter value of a sound which needs to be paid special attention by himself, the defect that the sounds in the prior art are mutually covered is overcome, and the sounds which need to be paid special attention by the user can be clearly heard.
