And the audio module of the standard mobile phone is a standard module, and the standard mobile phone is utilized to test the audio module of the test mobile phone. The test mobile phone keeps a call state with the standard mobile phone by dialing the number. The script refers to the extension of a batch file and is a combination of a series of operation actions performed by a determined control computer.
In the test stage, a local area network is built, and short messages and the like are transferred and sent through a central service number, namely, a test mobile phone dials the number of a standard mobile phone and is transferred to the standard mobile phone through the central service number, so that the test mobile phone is connected with the standard mobile phone (namely, a call state is kept), and the local area network is a self-built mobile phone communication base station through an ISP (Internet access service) network and is used for simulating the test, so that the network is stable and the call cannot be influenced. Wherein, through the adb tool of Python, adb-s < device name > shell service call AAAA, wherein AAAA represents the standard handset to be called, and the device name is the test handset controlled to dial the number.
In step S12, the computer controls the sound card of the computer to transmit the first test audio to the microphone of the test mobile phone through pyAudio module in Python (an interpreted, object-oriented, dynamic data type of high-level programming language), specifically, the speaker of the computer is directed to the microphone of the test mobile phone, so as to transmit the first test audio to the microphone of the test mobile phone. The first test audio is transmitted to the coding unit of the audio module of the test mobile phone through the test mobile phone microphone and is compiled into digital signals, and the digital signals are transmitted to the decoding unit of the audio module of the standard mobile phone when the test mobile phone microphone is in a call state with the standard mobile phone in the process of being infused with the first test audio, and the digital signals are converted into analog signals after being decoded and are played on the loudspeaker of the standard mobile phone;
and step S13, the computer informs the test server through the script to control the sound card of the test server to record the played first test audio from the standard mobile phone loudspeaker end through the pyAudio module, and then the test server forms the first test audio recorded by the sound card into a first recorded audio, and the first recorded audio is compared with the first test audio. Comparing with the first test audio means that a waveform diagram is drawn on the first test audio and the first recorded audio (such as wav or mp3 file), and FFT (fast fourier transform) processing is performed to obtain a spectrogram, and comparing the spectrogram of the first test audio and the spectrogram of the first recorded audio, if the accuracy rate reaches 90%, the comparison is qualified, which means that the forward test passes, that is, the coding unit of the audio module of the test mobile phone is qualified, otherwise the test fails.
Step S14, the computer informs the test server through the script to control the sound card of the test server to infuse the second test audio to the standard mobile phone microphone through the pyAudio module, the loudspeaker of the test server faces the standard mobile phone microphone, the second test audio is transmitted to the coding unit of the audio module of the standard mobile phone through the standard mobile phone microphone when the second test audio is infused to the standard mobile phone microphone, the digital signal is compiled into a digital signal, the digital signal is transmitted to the decoding unit of the audio module of the test mobile phone, and the digital signal is converted into an analog signal after being decoded and played on the loudspeaker of the test mobile phone;
and S15, the computer controls the sound card of the test server to record second test audio from the speaker end of the test mobile phone through the pyAudio module to form second recorded audio, and the second recorded audio is compared with the second test audio. The method of comparison may be the same as the comparison method in step 13. And if the comparison is qualified, the reverse test is passed, and the decoding unit of the audio module of the test mobile phone is qualified. So far, the audio module test of the test mobile phone is completed.
Preferably, in order to prevent the sound card of the test server from failing to record due to unstable network, the computer can be controlled by the script to continuously send the test audio multiple times until the sound card of the test server records the record audio file and feeds back to the computer signal, and the computer stops sending the test audio. Alternatively, the test server side and the computer side can be controlled by the script to continuously record until sound files, such as files in mp3 and wmv formats, are generated, and the sound files cannot be represented as successful in recording, i.e. can be compared with the original audio.
Second embodiment
Most of the contents of the second embodiment are the same as those of the first embodiment, and the same contents are omitted here.
In step S21, a plurality of test handsets (each handset has a number) may be controlled to simultaneously communicate with a standard handset on the test server, where each test handset is connected to the computer and the standard handset is connected to the test server. And the audio module of the standard mobile phone is a standard module, and the audio module of each test mobile phone is tested by using the standard mobile phone. Each test mobile phone keeps a call state with the standard mobile phone by dialing the number of the standard mobile phone.
In step S22, the computer controls the sound card of the computer to simultaneously infuse the first test audio to each test mobile phone microphone through the pyAudio module, specifically, the speaker of the computer may face the plurality of test mobile phone microphones, so as to simultaneously infuse the first test audio to each test mobile phone microphone. The first test audio is transmitted to the coding unit of the audio module of the test mobile phone through each test mobile phone microphone and is respectively compiled into different digital signals, and in the process of the first test audio being infused into the test mobile phone microphone, as the test mobile phone keeps a call state with the standard mobile phone, each digital signal is transmitted to the decoding unit of the audio module of the standard mobile phone, each digital signal is converted into a corresponding analog signal after being decoded and is played on the loudspeaker of the standard mobile phone, and specifically, each recorded section of the first test audio is played on the loudspeaker of the standard mobile phone in sequence. The buffer area can be arranged on the standard mobile phone to temporarily store the received digital signals, the digital signals firstly enter the buffer area for temporary storage and are decoded by the decoding unit one by one, the standard mobile phone loudspeaker plays, when one playing is completed, one digital signal is taken from the buffer area, the decoding unit decodes the digital signals, and the standard mobile phone loudspeaker plays.
Step S23, the sound card of the test server records each section of the first test audio played from the loudspeaker end of the standard mobile phone, and forms a first recorded audio. Because each section of the first test audio corresponds to the number of the test mobile phone, the test mobile phone corresponding to the first recorded audio formed by recording by the sound card of the test server can be known. And respectively comparing and testing with the original first test audio. Thus, the testing of the coding units of the audio modules of the plurality of test mobile phones is completed.
Step S24, the sound card of the test server sequentially infuses a plurality of pieces of second test audio to the standard mobile phone microphone according to time sequence, and the second test audio is transmitted to the coding unit of the audio module of the standard mobile phone through the standard mobile phone microphone when the standard mobile phone microphone is infused with the second test audio, and is compiled into a digital signal, and the digital signal is transmitted to the decoding unit of the audio module of each test mobile phone. The test mobile phone sequentially plays the second test audio according to the time sequence. For example, three test mobile phones are tested, the sound card of the test server sequentially infuses three sections of second test audio to the microphone of the standard mobile phone in time sequence, and when a first section of second test audio is infused, the first test mobile phone obtains the first section of second test audio and plays the first section of second test audio through a loudspeaker. Although the other two test mobile phones also obtain the first section of the second test audio at the same time, the other two test mobile phones are in a mute state at the moment and cannot cause interference to the sound card of the test server. Wherein the muting of any mobile phone speaker may be implemented with the adb tool of the Python script (Android Debug Bridge, i.e. android debug bridge). Specifically, it may be implemented with the command adb-s < device name > shell input keyevent <164>, where the device name is the number of the corresponding respective test handset, where 164 is the event value. And after the first test mobile phone finishes playing the first section of the second test audio, the first test mobile phone is turned into a mute state. And when the second section of second test audio is infused, the loudspeaker of the second test mobile phone plays the second section of second test audio, and so on.
In step S25, during the process of playing the second test audio by each test mobile phone, the computer controls the sound card of the test server to record the second test audio from the speaker end of the test mobile phone through the pyAudio module, so as to form a second recorded audio, and compares the second recorded audio with the second test audio of the corresponding section. The method of comparison may be the same as the comparison method in step 13. And if the comparison is qualified, the reverse test is passed, and the decoding unit of the audio module of the test mobile phone is qualified. So far, the audio module test of the plurality of test mobile phones is completed.
In addition, S22 and S23 of the second embodiment may also be to sequentially infuse the first test audio to the test mobile phone, so as to sequentially play the first test audio at the standard mobile phone end, thereby obtaining a plurality of first recorded audio, where the test speed is obviously slower.
