Based on the hardware structure of the mobile terminal 100 and the communication network system, various embodiments of the method of the present invention are provided.
First, the present invention provides an audio testing method, which is applied to the mobile terminal shown in fig. 1 to 2. Fig. 3 is a flowchart illustrating an implementation of the first embodiment of the audio testing method according to the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 3 may be changed and some steps may be omitted according to different requirements. The audio test method comprises the following steps:
step S301, when an audio test instruction is detected, obtaining an attribute value from the audio test instruction.
The audio test on the mobile terminal is usually realized by means of audio automatic test equipment, and a sound card and analysis software are arranged in the audio automatic test equipment. Referring to fig. 7, fig. 7 is a schematic diagram illustrating an embodiment of an audio test performed by an audio automation test device on a mobile terminal, where as shown in fig. 7, when analysis software on the audio automation test device wants to test the performance of an audio device, an audio test instruction needs to be sent to the mobile terminal, and when the mobile terminal detects the audio test instruction, an audio test is performed on the corresponding audio device. The audio device on the mobile terminal generally comprises two types of audio input devices and audio output devices, the audio input devices generally comprise a main microphone and an auxiliary microphone, the audio output devices generally comprise a loudspeaker and an earphone, and the audio test method and the audio test device are used for carrying out audio test, namely testing the performance of the main microphone, the auxiliary microphone, the loudspeaker or the earphone. Compared with the whole machine test in the prior art, the invention can carry out independent performance test on each audio device, therefore, the invention adopts the attribute mode to respectively set the audio test channels for the loudspeaker, the receiver, the main microphone and the auxiliary microphone, and for different audio devices, the audio test channels have different attribute values, namely, the attribute values are used for distinguishing different audio test channels. The audio test path is implemented by a QACT tool, and from the viewpoint of control flow, the audio test path uses an attribute (the attribute is referred to as an attribute value in the present invention) to specify which audio device is to operate or a group of audio devices is to operate, and the audio test path can be regarded as a test channel specially opened for a certain test purpose.
Step S302, determining an audio test path according to the attribute value.
In this embodiment, the audio test path includes four types, namely a main microphone test path, an auxiliary microphone test path, a speaker test path, and a receiver test path, where the main microphone test path and the auxiliary microphone test path are audio input device test paths, and the speaker test path and the receiver test path are audio output device test paths. Of course, if the audio device on the mobile terminal has other audio devices besides the main microphone, the sub-microphone, the speaker and the receiver, the corresponding audio test path can be set for the other audio devices in the same way, that is, the audio test path can be flexibly set for each audio device, and the audio test has strong expandability. Because the attribute values are in one-to-one correspondence with the audio test paths, the audio test paths can be determined according to the acquired attribute values.
Step S303, obtaining an audio device corresponding to the audio test path.
Specifically, the audio test paths and the audio devices have a one-to-one correspondence relationship, such as a main microphone test path, an auxiliary microphone test path, a loudspeaker test path, and a receiver test path, which correspond to the main microphone, the auxiliary microphone, the loudspeaker, and the receiver, respectively.
Step S304, using a test sound source as an input signal of the audio device, controlling the audio device to work, and transmitting an audio signal output by the audio device to audio automatic test equipment, so that the audio automatic test equipment analyzes the performance of the audio device according to the test sound source and the audio signal.
In the invention, after the mobile terminal determines the audio device through the attribute value, the audio device is controlled to work so as to carry out audio test on the audio device. Specifically, when the audio device is an audio output device, that is, the audio test path is an audio output device test path, the step of using the test sound source as the input signal of the audio device, controlling the audio device to operate, and transmitting the audio signal output by the audio device to the audio automation test equipment includes: (1) controlling the mobile terminal to start an audio output device, and taking the test sound source as an input signal of the audio output device; (2) and starting a standard microphone of the audio automatic test equipment to acquire the audio signal output by the audio output device. Using loudspeaker as an example, when carrying out audio test to loudspeaker, mobile terminal control loudspeaker broadcast the test sound source that sets up in advance, and audio frequency automation test equipment receives the audio signal of loudspeaker broadcast through standard microphone simultaneously, then analysis software compares received audio signal and built-in test sound source again to can obtain the distortion factor and the true loudness value of loudspeaker work under current environment, and then can obtain the correlation properties of loudspeaker. Since the receiver and the speaker are both audio output devices, the testing principle is the same, and the testing process of the receiver is not described in detail here. In addition, the test audio played by the loudspeaker or the receiver can be realized by a built-in sound source, and the built-in sound source is also specified by the audio automation equipment. When the audio device is an audio input device, that is, the audio test path is an audio input device test path, the step of using the test sound source as the input signal of the audio device, controlling the audio device to work, and transmitting the audio signal output by the audio device to the audio automatic test equipment includes: (1) controlling an audio input device to record a test sound source played by the audio automatic test equipment; (2) and outputting the test sound source collected by the audio input device to the audio automatic test equipment through an earphone channel. Using main microphone as an example, when carrying out the audio test to main microphone, audio frequency automation test equipment passes through artifical mouth broadcast test sound source, mobile terminal control main microphone records the test sound source of broadcast, then passes through the earphone route to the test sound source of recording and transmits for audio frequency automation test equipment, audio frequency automation test equipment carries out analysis processes to it again to the loudness value and the distortion factor value of acquireing main microphone, and then the performance of analysis main microphone. Similarly, the secondary microphone may be tested for audio frequency, and since the testing principles are the same, the testing process for the secondary microphone is not described in detail here.
Through the steps S301 to S304, when an audio test instruction is detected, the audio test method of the present invention obtains an attribute value from the audio test instruction, determines an audio test channel according to the attribute value, obtains an audio device corresponding to the audio test channel, then uses a test sound source as an input signal of the audio device, controls the audio device to operate, and transmits an audio signal output by the audio device to an audio automation test apparatus, so that the audio automation test apparatus analyzes the performance of the audio device according to the test sound source and the audio signal, because the audio test method of the present invention sets an independent audio test channel for each audio device in a manner of adopting the attribute value, it is realized that an audio test channel is flexibly set for each audio device, and the audio test has strong expandability; meanwhile, an independent audio test channel is arranged for each audio device, and the test result can accurately reflect the performance of the corresponding audio device.
Further, based on the first embodiment described above, a second embodiment of the audio testing method of the present invention is proposed. Fig. 4 is a flowchart illustrating an implementation of the second embodiment of the audio testing method according to the present invention. In this embodiment, the execution order of the steps in the flowchart shown in fig. 4 may be changed and some steps may be omitted according to different requirements. The audio test method comprises the following steps:
step S401, receiving and storing the corresponding relation between the attribute value set by the user and the audio test paths, wherein each audio test path corresponds to an audio xml configuration file, and the audio xml configuration file comprises the tinymix path which needs to be started when the audio test path is opened.
In order to implement the above audio testing method, the present invention needs to design an application layer, a HAL layer, an audio xml configuration file, and acdbID. The application layer is an APP, namely an audio test APP developed by the invention, the audio test APP is installed on the mobile terminal and is used for realizing the audio test method of the invention, a user can set attribute values for each audio device in the audio test APP, and when the audio test APP receives an audio test instruction, an audio test access can be determined according to the attribute values in the audio test instruction.
The audio xml configuration file is specifically a mixer _ paths _ mtp. xml file, and configuration paths with the formats of < path name "" > … </path > are stored in the file, and are a certain combination of the tinymix paths, for example, a plurality of tinymix paths need to be opened when a speaker plays, and a plurality of tinymix paths need to be opened when the speaker plays are stored in the audio xml configuration file. For example, the content of the part in the audio xml configuration file is as follows:
the tinymix pathway refers to tinymix RX1MIX1INP1RX1, that is, the < path > in the above document is a set of tinymix switches, which mainly functions to open many necessary tinymix pathways for the audio test pathway. The audio xml configuration file used to define the audio test path in the present invention is as follows:
<path name="speaker-test">…</path>
<path name="receiver-test">…</path>
<path name="mic1-test">…</path>
<path name="mic2-test">…</path>
the audio test path defined by the audio xml configuration file is associated with the HAL layer, and finally mapped to the audio xml configuration file at the HAL layer, so that each path (i.e. audio test path) is validated.
The HAL layer is an audio hardware abstraction layer, the HAL layer can work only by being matched with an audio xml configuration file, the HAL layer corresponds to two services, namely Audio Flanger. cpp and Audio policy service. cpp of an android audio frame, the Audio policy service is not a real device actually, and a manufacturer can conveniently customize an audio policy by adopting a virtual device mode. The task of the abstraction layer is to really associate the audioFlinger/audioPolicyservice with the hardware device, but to ensure that the change of the bottom layer does not affect the upper layer, so the HAL layer is a place where android suggests modification to the mobile phone manufacturer, and other parts of the audio frame are not modified generally. Specifically, when the xml configuration file is associated with the HAL layer, the mapping relationship is illustrated as follows: [ SND _ DEVICE _ OUT _ SPEAKER _ TEST ] - "spaker-TEST", where "spaker-TEST" refers to the < path name ═ spaker-TEST "> … </path > in the audio xml configuration file, and SND _ DEVICE _ OUT _ SPEAKER is the DEVICE sound card setting constant suggested in the android system, through which the HAL layer can be associated with the audio xml configuration file. Similarly, for the audio xml configuration files of other audio test paths, the following mapping relationship is set:
[SND_DEVICE_OUT_RECEIVER_TEST]="receiver-test"
[SND_DEVICE_OUT_MIC1_TEST]="mic1-test"
[SND_DEVICE_OUT_MIC2_TEST]="mic2-test"
in addition, the HAL layer is also associated with the acdbID, and the mapping relationship is as follows:
[SND_DEVICE_OUT_SPEAKER_TEST]="205"
[SND_DEVICE_OUT_RECEIVER_TEST]="204"
[SND_DEVICE_OUT_MIC1_TEST]="202"
[SND_DEVICE_OUT_MIC2_TEST]="201"
wherein 201, 202, 204 and 205 represent the values of acdbID, and different acdbIDs represent different sound effect parameters. In addition, the call logic can be distinguished by attribute values at the HAL layer, for example: when the audio output device is called, the call logic is platform _ get _ output _ snd _ device, and when the audio input device is called, the call logic is platform _ get _ input _ snd _ device. The two calling logics are determined by an Android system frame, the interface cannot be changed, and the calling logics are called certainly when the audio device is used. In order to distinguish the audio test path from the audio working path (i.e. the audio path when the mobile terminal is normally used), the present invention uses an attribute value to specify the path that we need to select, for example: when a loudspeaker TEST is performed, if the attribute value is not specified, a default loudspeaker playing path (audio working path) is selected for playing, and when the attribute value of the attribute debug.
Step S402, when an audio test instruction is detected, obtaining an attribute value from the audio test instruction.
Step S403, determining an audio test channel according to the attribute value, and acquiring an audio device corresponding to the audio test channel and a sound effect parameter corresponding to the audio test channel.
In this embodiment, the setting of the audio test path for each audio device is realized by a QACT tool, and the audio test path can be described from two aspects, that is, from the viewpoint of control flow, an attribute (the attribute corresponds to an attribute value) is used to specify which audio device operates or which group of audio devices operates, and the audio test path can be regarded as a test channel specially opened for a certain test purpose; from the audio effect angle, can distinguish the audio device sound effect parameter of normal use and the user is for during the test sound effect parameter that audio frequency test access set up through adding extra acdbID, also can say that has taken solitary sound effect access for a certain test purpose. It should be noted that, when the audio device is tested in the production process, the sound effect parameters of the audio test channel are set to be null, i.e. no extra sound effect parameters are used to reflect the performance of the audio device more truly, and if the test is developed, sound effect processing can be added according to the requirement, so as to develop whether some indexes of the sound effect which can be tested by using the audio automatic test equipment meet the design requirements of engineers, i.e. to facilitate the flexible debugging of the sound effect parameters by the sound effect engineers, when the audio effect is good, the corresponding sound effect parameters can be applied to the audio working channel used by the user, i.e. the conventional channel, the conventional channel refers to the channel which is added with the sound effect algorithm when the mobile phone is normally used, and is supplied for the user to use, therefore, some uncertain sound effect algorithms can be tested in the audio test channel in advance, and after the optimal sound effect parameters are obtained, the optimal sound effect parameters are added into an audio working channel used by a user.
Step S404, when the audio device is an audio output device, controlling the mobile terminal to start the audio output device, using the test sound source as an input signal of the audio output device, performing corresponding sound effect processing on the test sound source transmitted in the audio test channel according to the sound effect parameters, and starting a standard microphone of the audio automatic test equipment to collect an audio signal output by the audio output device, so that the audio automatic test equipment analyzes the performance of the audio device according to the test sound source and the audio signal.
In this embodiment, an audio test in the research and development process is taken as an example, and after a user sets a sound effect parameter for an audio test channel and acquires the sound effect parameter, the corresponding sound effect processing is performed on a test sound source transmitted in the audio test channel according to the sound effect parameter in the audio test process, so as to obtain an audio signal after the sound effect processing. Specifically, sound effect means that an additional algorithm is added when the audio device works: such as echo cancellation, noise reduction, etc., the addition of sound effect to the audio device is mainly to add an additional optimization algorithm, so that the sound quality displayed by the audio device is more consistent with the characteristics of human ears, and the sound is more comfortable and clear. Further, the step of controlling the operation of the audio device includes: acquiring an audio xml configuration file corresponding to the audio test channel; and opening a tinymix passage in the audio xml configuration file to realize the control of the operation of the audio device.
Step S405, when the audio device is an audio input device, controlling the audio input device to record a test sound source played by the audio automatic test equipment, simultaneously performing corresponding sound effect processing on the test sound source transmitted in the audio test channel according to the sound effect parameters, and outputting the test sound source after the sound effect processing to the audio automatic test equipment through an earphone channel so that the audio automatic test equipment analyzes the performance of the audio device according to the test sound source and the audio signal. Referring to fig. 8, fig. 8 is a schematic diagram illustrating another embodiment of an audio testing process performed by an audio automatic testing device on a mobile terminal, as shown in fig. 8, the audio testing process includes the following steps: 1. the audio automatic test equipment sends an audio test instruction to an audio test APP on the mobile terminal; 2. the audio test APP obtains an attribute value and sends the attribute value to the HAL layer; determining an audio test path by the HAL layer according to the attribute value; 4. the audio test APP obtains the ID of the audio device according to the attribute value analysis and sends the ID to the audio test channel, and sound effect processing can be carried out according to the acdbID while audio test is carried out in the embodiment; the HAL layer selects the audio device during the audio test according to the ID of the audio device; 6. feeding back the selection result of the audio device to the application layer; 7. controlling the audio device to work; 8. the audio device outputs an audio signal to the audio automatic test equipment; 9. the audio automatic test equipment analyzes the performance of the audio device through analysis software.

Meanwhile, the invention also provides a mobile terminal, which comprises a memory, a processor and an audio test program 400 which is stored on the memory and can be run on the processor. Fig. 5 is a functional block diagram of an audio test program 400 according to a first embodiment of the present invention. In this embodiment, the audio test program 400 may be divided into one or more modules, for example, in fig. 5, the audio test program 400 may be divided into an attribute value acquisition module 401, an audio test path determination module 402, an audio device acquisition module 403, and a control module 404. The module referred to in the present invention refers to a series of instruction segments of the fetcher program that can perform specific functions, and is more suitable than the fetcher program for describing the execution process of the software in the mobile terminal. The detailed description of the functions of the functional modules 401 and 404 will be described below. Wherein:
the attribute value obtaining module 401 is configured to obtain an attribute value from an audio test instruction when the audio test instruction is detected.
The audio test on the mobile terminal is usually realized by means of audio automatic test equipment, and a sound card and analysis software are arranged in the audio automatic test equipment. Referring to fig. 7, fig. 7 is a schematic diagram illustrating an embodiment of an audio test performed by an audio automation test device on a mobile terminal, where as shown in fig. 7, when analysis software on the audio automation test device wants to test the performance of an audio device, an audio test instruction needs to be sent to the mobile terminal, and when the mobile terminal detects the audio test instruction, an audio test is performed on the corresponding audio device. The audio device on the mobile terminal generally comprises two types of audio input devices and audio output devices, the audio input devices generally comprise a main microphone and an auxiliary microphone, the audio output devices generally comprise a loudspeaker and an earphone, and the audio test method and the audio test device are used for carrying out audio test, namely testing the performance of the main microphone, the auxiliary microphone, the loudspeaker or the earphone. Compared with the whole machine test in the prior art, the invention can carry out independent performance test on each audio device, therefore, the invention adopts the attribute mode to respectively set the audio test channels for the loudspeaker, the receiver, the main microphone and the auxiliary microphone, and for different audio devices, the audio test channels have different attribute values, namely, the attribute values are used for distinguishing different audio test channels. The audio test path is implemented by a QACT tool, and from the viewpoint of control flow, the audio test path uses an attribute (the attribute is referred to as an attribute value in the present invention) to specify which audio device is to operate or a group of audio devices is to operate, and the audio test path can be regarded as a test channel specially opened for a certain test purpose.
The audio test path determining module 402 is configured to determine an audio test path according to the attribute value.
In this embodiment, the audio test path includes four types, namely a main microphone test path, an auxiliary microphone test path, a speaker test path, and a receiver test path, where the main microphone test path and the auxiliary microphone test path are audio input device test paths, and the speaker test path and the receiver test path are audio output device test paths. Of course, if the audio device on the mobile terminal has other audio devices besides the main microphone, the sub-microphone, the speaker and the receiver, the corresponding audio test path can be set for the other audio devices in the same way, that is, the audio test path can be flexibly set for each audio device, and the audio test has strong expandability. Because the attribute values are in one-to-one correspondence with the audio test paths, the audio test paths can be determined according to the acquired attribute values.
The audio device obtaining module 403 is configured to obtain an audio device corresponding to the audio test path. Specifically, the audio test paths and the audio devices have a one-to-one correspondence relationship, such as a main microphone test path, an auxiliary microphone test path, a loudspeaker test path, and a receiver test path, which correspond to the main microphone, the auxiliary microphone, the loudspeaker, and the receiver, respectively.
The control module 404 is configured to use a test sound source as an input signal of the audio device, control the audio device to operate, and transmit an audio signal output by the audio device to an audio automation test device, so that the audio automation test device analyzes the performance of the audio device according to the test sound source and the audio signal.
In the invention, after the mobile terminal determines the audio device through the attribute value, the audio device is controlled to work so as to carry out audio test on the audio device. Specifically, when the audio device is an audio output device, that is, the audio test path is an audio output device test path, the step of using the test sound source as the input signal of the audio device, controlling the audio device to operate, and transmitting the audio signal output by the audio device to the audio automation test equipment includes: (1) controlling the mobile terminal to start an audio output device, and taking the test sound source as an input signal of the audio output device; (2) and starting a standard microphone of the audio automatic test equipment to acquire the audio signal output by the audio output device. Using loudspeaker as an example, when carrying out audio test to loudspeaker, mobile terminal control loudspeaker broadcast the test sound source that sets up in advance, and audio frequency automation test equipment receives the audio signal of loudspeaker broadcast through standard microphone simultaneously, then analysis software compares received audio signal and built-in test sound source again to can obtain the distortion factor and the true loudness value of loudspeaker work under current environment, and then can obtain the correlation properties of loudspeaker. Since the receiver and the speaker are both audio output devices, the testing principle is the same, and the testing process of the receiver is not described in detail here. In addition, the test audio played by the loudspeaker or the receiver can be realized by a built-in sound source, and the built-in sound source is also specified by the audio automation equipment. When the audio device is an audio input device, that is, the audio test path is an audio input device test path, the step of using the test sound source as the input signal of the audio device, controlling the audio device to work, and transmitting the audio signal output by the audio device to the audio automatic test equipment includes: (1) controlling an audio input device to record a test sound source played by the audio automatic test equipment; (2) and outputting the test sound source collected by the audio input device to the audio automatic test equipment through an earphone channel. Using main microphone as an example, when carrying out the audio test to main microphone, audio frequency automation test equipment passes through artifical mouth broadcast test sound source, mobile terminal control main microphone records the test sound source of broadcast, then passes through the earphone route to the test sound source of recording and transmits for audio frequency automation test equipment, audio frequency automation test equipment carries out analysis processes to it again to the loudness value and the distortion factor value of acquireing main microphone, and then the performance of analysis main microphone. Similarly, the secondary microphone may be tested for audio frequency, and since the testing principles are the same, the testing process for the secondary microphone is not described in detail here.
Through the modules 401 to 404, when an audio test instruction is detected by the audio test program, an attribute value is obtained from the audio test instruction, an audio test channel is determined according to the attribute value, an audio device corresponding to the audio test channel is obtained, then a test sound source is used as an input signal of the audio device, the audio device is controlled to work, and an audio signal output by the audio device is transmitted to an audio automatic test device, so that the audio automatic test device analyzes the performance of the audio device according to the test sound source and the audio signal; meanwhile, an independent audio test channel is arranged for each audio device, and the test result can accurately reflect the performance of the corresponding audio device.
Further, based on the above-mentioned first embodiment of the audio test program 400 of the present invention, a second embodiment of the audio test program 400 of the present invention is proposed.

In order to implement the above audio test program, the present invention needs to design the application layer, the HAL layer, the audio xml configuration file, and the acdbID. The application layer is an APP, namely an audio test APP developed by the invention, the audio test APP is installed on the mobile terminal and is used for realizing the audio test method of the invention, a user can set attribute values for each audio device in the audio test APP, and when the audio test APP receives an audio test instruction, an audio test access can be determined according to the attribute values in the audio test instruction.
The audio xml configuration file is specifically a mixer _ paths _ mtp. xml file, and configuration paths with the formats of < path name "" > … </path > are stored in the file, and are a certain combination of the tinymix paths, for example, a plurality of tinymix paths need to be opened when a speaker plays, and a plurality of tinymix paths need to be opened when the speaker plays are stored in the audio xml configuration file. For example, the content of the part in the audio xml configuration file is as follows:
the tinymix pathway refers to tinymix RX1MIX1INP1RX1, that is, the < path > in the above document is a set of tinymix switches, which mainly functions to open many necessary tinymix pathways for the audio test pathway. The audio xml configuration file used to define the audio test path in the present invention is as follows:
<path name="speaker-test">…</path>

Specifically, when the xml configuration file is associated with the HAL layer, the mapping relationship is illustrated as follows: [ SND _ DEVICE _ OUT _ SPEAKER _ TEST ] - "spaker-TEST", where "spaker-TEST" refers to the < path name ═ spaker-TEST "> … </path > in the audio xml configuration file, and SND _ DEVICE _ OUT _ SPEAKER is the DEVICE sound card setting constant suggested in the android system, through which the HAL layer can be associated with the audio xml configuration file.

[SND_DEVICE_OUT_MIC2_TEST]="201"
wherein 201, 202, 204 and 205 represent the values of acdbID, and different acdbIDs represent different sound effect parameters. In addition, the call logic can be distinguished by attribute values at the HAL layer, for example: when the audio output device is called, the call logic is platform _ get _ output _ snd _ device, and when the audio input device is called, the call logic is platform _ get _ input _ snd _ device. The two calling logics are determined by an Android system frame, the interface cannot be changed, and the calling logics are called certainly when the audio device is used.
