Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
Referring to fig. 1, in an embodiment of the present invention, a processing method for a VoIP sound at an android phone end is applied to a client, where the client is in communication connection with a server, and the method includes:
s11, detecting the configuration file, and judging whether the configuration file is the latest version;
s12, if not, sending a configuration file transmission request to a server and receiving a configuration file sent by the server;
s13, if yes, detecting the equipment model of the client, and judging whether the equipment model is matched with the model parameters in the configuration file;
s14, if matching, obtaining the audio parameters corresponding to the model parameters in the configuration file, and setting the audio processing module of the client according to the audio parameters;
s15, if not, acquiring default parameters, and setting the audio processing module of the client according to the default parameters;
further comprising:
s16, acquiring data collected by a microphone, and performing VAD detection and volume monitoring to obtain VAD state values and volume values;
s17, carrying out statistical analysis on the VAD state value and the volume value to obtain the VAD state statistical value and the volume statistical value in unit time;
s18, judging whether the VAD state statistic value and the volume statistic value are lower than a preset VAD state statistic value threshold and a volume statistic value threshold or not;
and if the value is lower than the preset value, S19, acquiring the equipment model of the client and sending the equipment model to a server.
If not, the audio processing is normally performed using the audio processing module already set in step S14 or S15.
Specifically, Voice Activity Detection (VAD), also called Voice endpoint Detection, Voice boundary Detection, aims to identify and eliminate a long-time mute period from a Voice signal stream, so as to achieve the effect of saving Voice channel resources without reducing service quality, and is an important component of IP telephone application.
Specifically, a configuration file is detected, and whether the configuration file is the latest version or not is judged; and if not, sending a configuration file transmission request to the server, and receiving the configuration file sent by the server.
It should be noted that, because the ALSA architecture is too bulky, many functions are unavailable for the embedded device, and power consumption is increased, the Android (Android) adopts a simplified tinyalsa, and the tinyalsa-related bottom debugging tools commonly used include tinymix, tinyplay, and tinycap, where the tinymix can view an audio control of the system and can be directly executed for viewing, and the tinymix has more functions of manually setting a value of the control; the tinyplay can also be used for directly playing wav format files, and before playing, the tinymix is required to be used for setting related controls; the tinycap is used for recording, a control related to recording needs to be set before the tinycap is used, the client detects the configuration file of the android mobile phone terminal device, searches for corresponding file content, and checks whether the configuration file exists, and the problem that the configuration file is lost or unsuccessfully configured due to system error or configuration failure exists, so that the configuration file of the android mobile phone terminal device needs to be detected first.
Further, the configuration file may not be the latest version, and a problem that the configuration file is not the latest version when the client detects the configuration file may occur because the new version is not covered or the server does not issue the new configuration file, at this time, the client needs to send a request for configuration file transmission to the server to download the new configuration file from the server.
Specifically, if yes, the device model of the client is detected, and whether the device model is matched with model parameters in a configuration file is judged. It should be noted that after the client checks the configuration file, a loading step is performed, and further analysis is performed on the audio parameters, and meanwhile, the device model of the android phone terminal is detected, and is matched with the audio parameters, different device models of the android phone terminal are matched with corresponding different audio parameters, if the matching is consistent, the audio parameters are set according to the corresponding model, and an audio processing module of the device runs according to the corresponding parameters, so that the opposite terminal hears the volume of the device in a moderate size, and the problem that sound is suddenly changed or sound cannot be heard in a small size is avoided, and if the matching is inconsistent, default parameters are set for the audio processing module of the device to continue running, so that the formats of the audio parameters are unified.
Further, the audio parameters include the following: the method comprises the following steps of sampling digit number, bit rate, audio sampling rate (namely audio sampling level), channels (namely channel number) and resolution (namely sampling precision), wherein the sampling digit number can be understood as the resolution of sound processed by an acquisition card, the higher the value of the number is, the higher the resolution is, the truer the recorded and played back sound is, 8 bits represent 8 power-256 of 2, and 16 bits represent 16 power-64K of 2; the bit rate is expressed as the size of audio data volume per second after compression coding aiming at the coding format; the audio sampling rate (i.e. audio sampling level) refers to the number of times the sound signal is sampled by the recording device in one second, and the higher the sampling frequency is, the truer and more natural the sound is. On a mainstream acquisition card, the sampling frequency is generally divided into three grades of 22.05KHz, 44.1KHz and 48KHz, 22.05KHz can only reach the sound quality of FM broadcasting, 44.1KHz is the theoretical CD tone quality limit, and 48KHz is more accurate; the channel (i.e., number of channels) represents the presence of several channels of audio data; the resolution (i.e., sampling accuracy) represents the number of bits of data per acquisition.
Specifically, if the audio parameters are matched, the audio parameters in the configuration file are obtained, and an audio processing module of the client is set according to the audio parameters; and if not, acquiring default parameters, and setting an audio processing module of the client according to the default parameters. It should be noted that the client loads the configuration file and parses the audio parameters. The client detects the android mobile phone device model and matches the model in the audio parameters, if the matching is consistent, the setting is carried out according to the audio parameters of the corresponding model, the audio processing module of the device runs according to the corresponding parameters, the problem of small sound is solved, and the opposite end can hear the volume of the device in a moderate manner. And if the client detects that the model parameter of the equipment is not matched with the configuration parameter, setting a default parameter to an audio processing module of the equipment. If the audio parameters of the matched models cannot be detected, default parameters can be adopted, and the situation that the client cannot work due to the fact that no audio parameters exist is prevented.
Specifically, the client also acquires data acquired by the microphone, and performs VAD detection and volume monitoring to obtain a VAD state value and a volume value; and carrying out statistical analysis on the VAD state value and the volume value to obtain the VAD state statistic value and the volume statistic value in unit time, and judging whether the VAD state statistic value and the volume statistic value are both lower than a preset VAD state statistic value threshold value and a preset volume statistic value threshold value. The preset VAD state statistic threshold and the volume statistic threshold may be thresholds set by those skilled in the art according to actual needs, or thresholds obtained by the server through cloud computing. That is, the two thresholds may be dynamically varied.
Specifically, when the client runs, a closed loop is implemented as compared with the step of detecting the configuration file, in this step, in the execution process, a calculated statistical value in a unit time (for example, "1" second) needs to be compared with a set threshold, if the statistical value is lower than the threshold, it is determined that the VoIP sound of the device is small, the device model parameter of the android phone end is read, the model of the device is uploaded to the server, and then the client runs; if the statistic value is higher than the threshold value, namely the VoIP of the equipment is normal, the set audio processing module is directly operated by the client.
In an embodiment, further, the processing method for VoIP at the android phone end of the present invention further includes setting a function of a microphone of the client as a sound reception function when the VAD state statistic and the volume statistic are both lower than a preset statistic threshold.
It should be noted that, the VoIP application of the android phone end device collects original voice data through the microphone, and further, through setting AudioSource of the microphone, it may select to use audio processing of an android system or use external audio processing, if the AudioSource is set to be in a voice communication mode, the application may start the audio processing of the android system to perform echo cancellation and noise reduction processing, and perform processing with default parameters, this method is suitable for most of the android phone end devices, but for the android phone end device with small VoIP sound, the AudioSource needs to be set to be in a microphone mode, that is, the function of the microphone is set to be a radio reception function, at this time, the audio processing of the android system is turned off, and echo cancellation, noise reduction, automatic gain control and the like are implemented by using external audio processing, and the external audio processing may be according to problem characteristics, the audio processing algorithm parameters such as the microphone gain, the echo processing system delay, the processing level, the noise reduction algorithm parameters, the automatic gain control level and the like are adjusted in a targeted manner, so that the VoIP voice quality and the volume of the android terminal device are good, and finally the android terminal device can communicate through the normal VoIP voice.
In an embodiment, to solve the problem of small sound of VoIP at an android phone end, the processing system for small sound of VoIP at the android phone end provided in this embodiment is applied to a client, where the client is in communication connection with a server, and the system includes:
the analysis module is used for carrying out statistical analysis on the VAD state value and the volume value to obtain the VAD state statistical value and the volume statistical value in unit time;
the detection module is used for detecting a configuration file, judging whether the configuration file is the latest version or not, detecting the equipment model of the client, judging whether the equipment model is matched with model parameters in the configuration file or not, and judging whether the VAD state statistic value and the volume statistic value are both lower than a preset statistic value threshold or not;

and the acquisition module is used for acquiring data acquired by the microphone, performing VAD detection and volume monitoring to obtain a VAD state value and a volume value.
Specifically, the analysis module is configured to perform statistical analysis on the VAD state value and the volume value to obtain a VAD state statistical value and a volume statistical value in unit time. The client detects data collected by a microphone of the android mobile phone end equipment in real time, carries out VAD detection on the data, identifies and eliminates invalid signals in sound signals, further monitors volume and analyzes the volume at present.
Specifically, the detection module is configured to detect a configuration file, determine whether the configuration file is the latest version, detect the device model of the client, determine whether the device model is matched with model parameters in the configuration file, and determine whether both the VAD state statistic and the volume statistic are lower than a preset statistic threshold. The client detects the configuration file of the android mobile phone terminal equipment, searches for corresponding file content, and checks whether the configuration file exists, and the configuration file is lost or unsuccessfully configured due to system error or configuration failure, so that the configuration file of the android mobile phone terminal equipment needs to be detected first. And the detection module is also used for judging whether the model of the equipment is matched with the model parameters in the configuration file or not and judging whether the VAD state statistic value and the volume statistic value are both lower than a preset statistic value threshold or not.
