Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
It should be understood that the terms first, second, and the like in the description and in the claims and drawings are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the invention. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the described embodiments of the invention may be combined with other embodiments.
Herein, the audio device refers to an audio output device including a speaker (or a loudspeaker), a sound box, or the like, or an audio input device including a microphone (or a microphone).
The terminal comprises terminal equipment such as a desktop computer, a notebook computer, a palm computer, a tablet personal computer and the like. The terminal and the audio equipment can be in wired communication or wireless communication, wherein the wired communication mode comprises USB communication, serial communication and the like, and the wireless communication mode comprises Bluetooth communication, wiFi communication and the like. In the embodiment of the invention, the terminal is used for executing the audio hardware parameter setting method, namely executing the method for modifying the audio hardware parameter in the audio driving software.
In the prior art, since the audio driver software of one version is only suitable for audio equipment with one audio hardware parameter requirement, when the audio equipment connected with the terminal is replaced, relevant configuration of the audio driver software needs to be correspondingly modified, so that the modification difficulty is high, the operation is inconvenient, and bad use experience is brought to users. The application provides an audio hardware parameter modification method which can dynamically modify the audio hardware coefficient of target audio equipment and has simple modification operation.
Referring to fig. 1, fig. 1 is a schematic view of a scenario of an audio hardware parameter setting method according to an embodiment of the present invention; in fig. 1, the audio device is exemplified by a speaker, the terminal 102 is a computer, and if the audio device connected to the computer at the previous time is speaker 1 and the audio hardware parameter set by the user 101 for the speaker 1 is a, the audio hardware parameter stored in the configurable structure is a. When the audio device is replaced by the loudspeaker 2, the audio hardware parameter set by the user 101 for the loudspeaker 2 is B, and at this time, the computer updates the variable value of the configurable structure from A to B by calling the first callback function. When the user needs to utilize the loudspeaker 2 to play audio, that is, the computer receives an audio operation instruction (assumed to be an audio playing instruction) for the loudspeaker 2, the computer refreshes the current audio hardware parameters of the loudspeaker 2 (the audio hardware parameters before refreshing are still a) according to the updated configurable structure (the audio hardware parameters in the configurable structure are B at this time), so that the loudspeaker 2 executes an operation corresponding to the audio operation instruction, that is, an audio playing operation according to the audio hardware parameters (B).
It can be seen from the above that, by using the audio hardware parameter setting method of the embodiment of the present invention, the audio hardware parameters of the audio device can be dynamically set, and the user only needs to input the audio hardware parameters of the audio device to be set, without modifying the code each time, so that the operation is simple and convenient, and the audio hardware parameters can be adapted to the audio device, thereby effectively improving the user experience.
Fig. 2 is a schematic flow chart of an audio hardware parameter setting method according to an embodiment of the present invention; the audio hardware parameter setting method comprises the following steps:
201. Acquiring audio hardware parameters set by a user aiming at target audio equipment, wherein the audio hardware parameters are set parameters of an audio bus;
specifically, the audio hardware parameters include a clock of an audio bus, a frame synchronization timing mode, an operation mode, and the like. The audio buses include an I2S bus and a PCM bus, the I2S being commonly referred to as Inter-IC Sound, INTEGRATED INTERCHIP Sound, or IIS for short. Only one master device and transmitting device can exist simultaneously on the I2S bus. The master device may be a transmitting device, a receiving device, or other control device that coordinates the transmitting device and the receiving device. In the I2S system, devices providing clocks (SCK and WS) are master devices. The I2S is divided into three different modes of operation, a standard I2S mode, a left aligned mode and a right aligned mode, respectively.
PCM (Pulse Code Modulation) is a method of digitizing an analog signal by sampling at equal intervals (i.e., sampling rate clock cycles). The PCM digital audio interface, i.e. the audio data transmitted over the interface, is obtained by PCM sampling. The frame synchronization timing modes include a long frame synchronization mode and a short frame synchronization mode. The modes of operation of the PCM bus include ST-BUS, GCI, mcBSP modes.
202. Calling a first callback function, updating variable values in a configurable structural body according to the set audio hardware parameters, wherein the configurable structural body is used for storing the audio hardware parameters of the audio equipment, and the first callback function is used for realizing parameter setting of the configurable structural body through names of the audio hardware parameters;
Specifically, with the first callback function, the specific value of the corresponding audio hardware parameter in the configurable fabric may be modified according to the name of the audio hardware parameter.
203. Responding to the audio operation instruction of the target audio equipment, refreshing the current audio hardware parameters of the target audio equipment according to the updated configurable structural body, and executing the operation corresponding to the audio operation instruction.
Specifically, in order to avoid POP sound (POP sound refers to POP sound generated by transient impact caused by various operations after the audio device is powered on and powered off at the moment and after the power on is stable), after receiving an audio operation instruction of a user for the target audio device, audio hardware parameters of the target audio device are refreshed, and an operation corresponding to the audio operation instruction is executed. The audio operation instruction comprises an audio playing instruction and an audio acquisition instruction (such as recording and the like).
Therefore, the method of the embodiment of the invention can realize the dynamic modification of the audio hardware coefficient of the target audio equipment, has simple modification operation and effectively improves the user experience. In addition, the workload of debugging the audio driving software can be reduced to a great extent, and meanwhile, the compatibility and portability of the audio driving software version are improved.
In the embodiment of the invention, a structural body for storing audio hardware parameters is designed, namely a configurable structural body is used for storing all possible audio hardware parameters of the audio equipment. Wherein, different parameter variables in the configurable structural body represent different hardware parameters of the audio bus respectively, the audio hardware parameters take clock, frame synchronization time sequence mode and operation mode as examples, and the configurable structural body at this time can be:
In one possible embodiment, before performing step 201, the method further comprises:
s1, acquiring configuration parameters of audio equipment in an equipment tree;
Specifically, configuration parameters about audio devices in a device tree of the terminal are acquired. The configuration parameters in the device tree may be any configuration parameters of the audio device, and are not particularly limited.
S2, initializing and filling each member variable in the configurable structural body according to the configuration parameters of the audio equipment in the equipment tree.
Specifically, in the drive loading stage, the configuration items in the equipment tree are read, the values of the member variables in the corresponding structural body are filled, and the normal use of the default configuration of the equipment tree is ensured, so that the normal initialization state is ensured.
Further, when initializing the audio driver software, a first callback function (put function) and a second callback function (get function) of each audio hardware parameter in the configurable structure are required to be registered, so that the upper layer can read the current audio hardware parameter of the audio device through the name of the audio hardware parameter, or can set the variable value in the configurable structure through the name of the audio hardware parameter. For example, a snd_dai_new structure is defined, and is used for registering callback functions of each audio hardware parameter, and get and put functions of a user layer are implemented in each callback function, such as:
A callback function registering each audio hardware parameter is used for reading or setting the audio hardware parameter by the upper layer through the name:
static const struct snd_dai_new dai_params_config[]{
{.name＝“AUX_PCM Clock”,.get＝dai_params_clock_get,.put＝
dai_params_clocks_put},
…
}。
in addition, different kcontrol controls are registered in the audio driving software according to the configuration of the snd_dai_new structure, and the registered controls are used for setting parameters of a user layer.
In one possible embodiment, step 203 includes:
2031. Responding to the audio operation instruction, calling a second callback function to acquire the current audio hardware parameter of the target audio device, wherein the second callback function is used for reading the audio hardware parameter through the name of the audio hardware parameter;
specifically, after receiving the audio operation instruction, the terminal may obtain the specific values of all the current audio hardware parameters of the target audio device by calling the second callback function.
2032. When the updated audio hardware parameters of the configurable structure body are different from the current audio hardware parameters, a parameter refreshing function is called to refresh the audio hardware parameters of the target audio equipment, and an operation corresponding to the audio operation instruction is executed;
Specifically, when the updated audio hardware parameters in the configurable structure body are different from the current audio hardware parameters obtained in step 2031, it indicates that the audio hardware parameters of the target audio device need to be refreshed, at this time, a parameter refreshing function is called to refresh, the audio hardware parameters of the target audio device are refreshed to the audio hardware parameters of the configurable structure body, and then an operation corresponding to the audio operation instruction is executed. The parameter refreshing function may be a flush function or other functions. Further, the audio hardware parameters in the updated configurable structure at the moment can be saved as power-down backup data; and outputs parameter setting success information so that the user knows the parameter setting result. The power down backup data can be stored in a nonvolatile storage medium so as to realize that the data can still be stored after power down.
The mode of outputting the parameter setting success information can be that the parameter setting success information is directly displayed on the terminal or a message such as a short message, a QQ or a WeChat is sent to a preset user terminal.
2033. And when the updated audio hardware parameters of the configurable structural body are the same as the current audio hardware parameters, outputting parameter setting success information, and executing the operation corresponding to the audio operation instruction.
Specifically, the output manner of the parameter setting success information is the same as that of step 2032, and will not be described again.
In particular, 2031, 2032 and 2033 are only for distinguishing between different steps, and the order of execution of these steps is not limited.
Therefore, in the parameter modification process, the parameter updating judgment can be performed, and the dynamic modification can be realized.
In one possible embodiment, due to the audio hardware parameters stored in the power-down state, in order to avoid pop sound caused by repeated setting, the user experience is optimized, and after power-up, after the audio hardware parameters set by the user are obtained, the method further includes:
s3, acquiring power-down backup data;
Specifically, as can be seen from the description of step 2032, the power-down backup data is stored with audio hardware parameters set by the user for refreshing, and when the parameters are stored, the corresponding relationship between the storage time and the audio hardware parameters may be stored, for example, in the form of a table. Further, only the audio hardware parameters with the latest time can be reserved, namely, when new audio hardware parameters needing to be stored exist in the mode of overlaying storage, the audio hardware parameters with the older time are overlaid. It is also possible to save a fixed time interval or a preset number of audio hardware parameters, e.g. only audio hardware parameter data with a time interval within 2 days or 5 days (or other time interval) is reserved. Or only 3 or 5 (or other numbers) audio hardware parameters are reserved, and can be set according to the needs.
After the audio hardware parameters set by the user are obtained, data recovery can be performed from the backup area (namely the nonvolatile storage medium) of the terminal, and the audio hardware parameters at the latest power-down time in the power-down backup data are obtained.
S4, outputting parameter setting success information when the audio hardware parameters at the latest power-down time in the power-down backup data are the same as the set audio hardware parameters;
specifically, when the audio hardware parameter at the latest power-down time is the same as the set audio hardware parameter, it indicates that the current audio hardware parameter of the audio device is the same as the audio hardware parameter which the user wants to set, and the configurable structure body does not need to be updated, and at this time, parameter setting success information is output. When an audio operation instruction for a target audio device is received, an operation corresponding to the audio operation instruction may be directly performed.
S5, when the audio hardware parameter at the latest power-down time is different from the set audio hardware parameter, executing and calling a first callback function, and updating the variable value in the configurable structural body according to the set audio hardware parameter.
Specifically, when the audio hardware parameter at the latest power-down time is different from the set audio hardware parameter, it indicates that the current audio hardware parameter of the audio device is different from the audio hardware parameter that the user wants to set, and at this time, the configurable structure needs to be updated, that is, step 202 and step 203 are performed.
When the configurable structure is updated, the audio hardware parameters set by the user can be transferred to the first callback function by calling the amix function, so that the first callback function correspondingly modifies the data of the configurable structure according to the names of the audio hardware parameters, and the configurable structure is updated.
Also, S3, S4 and S5 in the foregoing description are merely for distinguishing between different steps, and the order of execution of these steps is not limited.
In one possible embodiment, when the audio hardware parameters set by the user are acquired, information input by the user can be received through a preset interface; in addition, a historical data selection window can be provided, the historical data displayed in the window is power-down backup data (more than one data), and a user can directly select the audio hardware parameters to be set by clicking without manually inputting, so that the user experience is improved.
