Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent 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.
As shown in fig. 1, there are two ways for inputting audio: calling a standard recording interface (namely an Android standard recording interface) to drive equipment to record through an application 1; and calling the development kit interface of the equipment customized development kit to drive equipment recording through the application 2. For the first mode, if a standard recording interface common to android is used, the device can only be used as a universal device, the recording effect is general, the delay is high, but the mode cannot obtain the optimized experience of the customized development kit provided by the device manufacturer. For the second mode, if the development kit interface corresponding to the device customization development kit is used, the recording effect is good, and the time delay is low, but the mode needs to bind the application and the device, and other devices cannot be used.
Because each equipment customization development kit is developed by a developer aiming at specific equipment, corresponding development kit interfaces are different, so that the problem of selectivity is brought to an application developer, the application developer needs to learn the customization interfaces of different manufacturers, the development cost is increased, and the development efficiency is reduced.
At present, because the interface of the development kit in the customized development kit of different hardware manufacturers is different, when the device customization kit provided by a certain manufacturer is selected, only the audio input device matched with the device customization kit can be used for recording, and the devices of other manufacturers cannot be used, so that inconvenience is brought to the use of a user.
For the convenience of understanding the present embodiment, a detailed description will be given to an audio input control method disclosed in the present embodiment.
As shown in fig. 2, in one embodiment of the present invention, there is provided an audio input control method applied to middleware of a host device connected to at least one audio input device, the method including the following steps.
S101, if the middleware is started, determining the audio input equipment currently connected with the host equipment.
Specifically, after the middleware is started, the method further includes the following steps before the audio input device currently connected to the host device is determined.
The middleware sends a query request to the underlying operating system.
The middleware receives query information returned by the bottom operating system according to the query request, wherein the query information comprises: a device identification of the currently connected audio input device.
For example, a recording DEVICE such as an earphone with a microphone, a SPEAKER, a microphone, and a remote controller with a recording function connected to the host DEVICE is identified as "AUDIO _ DEVICE _ OUT _ wide _ playback", and a DEVICE identification of an earphone is identified as "AUDIO _ DEVICE _ OUT _ speech", and the like.
And S102, determining a target audio device in the currently connected audio input devices.
In practical applications, after the middleware is started, the method further includes the following steps.
And receiving preset priority information input by a user.
And storing the preset priority information under a preset path.
The middleware reads preset priority information and determines target audio equipment in currently connected audio input equipment according to the preset priority information.
For example, the preset priority information includes priority level allocation information, "microphone-0", using different audio devices; "earphone-1"; a remote controller with a microphone-2, etc. If the host device is currently connected with a microphone, an earphone and a remote controller with a microphone, the microphone is preferentially used as the target audio device. In all examples shown and described herein, any particular value should be construed as merely exemplary, and not as a limitation, and thus other examples of example embodiments may have different values.
S103, if the fact that the development kit corresponding to the target audio equipment is installed is determined, the development kit interface of the development kit is called to drive the target audio equipment to record.
In practical application, after the middleware selects the target audio device to be used, the middleware may determine whether a development kit corresponding to the target audio device is installed in its memory. The following two cases are specifically distinguished:
if the development kit corresponding to the target audio equipment is determined to be installed, calling a development kit interface of the development kit to drive the target audio equipment to record;
and if the development kit corresponding to the target audio equipment is determined not to be installed, calling a standard recording interface of the host equipment to drive the target audio equipment to record. Thus, the original recording standard flow is completely compatible with the previous version.
The embodiment of the invention provides an audio input control method, which overcomes the defect that a plurality of devices cannot be used by recording application, and can select an applicable recording device according to preconfigured information by setting a middleware between an application layer and a bottom layer driver so as to meet the actual needs of users.
In another embodiment of the present invention, as shown in fig. 3, there is provided an audio input control method applied in a standard recording interface of a host device, the method comprising the following steps.
S201, obtaining the zone bit information stored in the preset storage position.
Specifically, when the Application (APP) of the host device receives a recording instruction input by a user, the APP calls a standard recording interface to determine whether to use the middleware. And the standard recording interface reads the zone bit information stored in a preset storage position in the memory and judges whether the zone bit information meets a preset condition.
S202, if the flag bit information is determined to meet the preset condition, the middleware is started.
Specifically, when the flag bit information satisfies a preset condition (for example, the flag bit information is 1), the middleware is started.
And when the flag bit information is determined not to meet the preset condition, determining target audio equipment in the currently connected audio input equipment according to the preset priority information, and driving the target audio equipment to record by using a standard recording interface.
The following specifically illustrates the working principle of the audio input control method provided by the embodiment of the present invention by way of example:
as shown in fig. 4, to provide a control middleware that can shield the proprietary interface of the device vendor, and a plurality of device customization development kits are integrated in the space. As shown in fig. 5, the recording process provided by the embodiment of the present invention is as follows:
1. and after the application receives the recording starting instruction, calling an Android standard recording interface, and starting or disabling the middleware by reading the flag bit information and the like through the Android standard recording interface. And if the middleware is forbidden, executing an Android standard recording process, namely driving equipment to record by using an Android standard recording interface, so that the equipment is completely compatible with the previous version.
2. If the middleware is started, the middleware determines at least one audio input device currently connected with the host device according to query information acquired by the bottom operating system, and selects a target audio device to be used from the plurality of currently connected audio devices according to preset priority information configured in advance.
3. The middleware detects whether a manufacturer customized development kit corresponding to the selected target audio equipment is installed in a memory of the middleware, and if the manufacturer customized development kit corresponding to the selected target audio equipment is installed in the memory of the middleware, a development kit interface of the development kit is called to drive the target audio equipment to record; and if the corresponding manufacturer customized development kit is not installed, executing an Android standard recording process, namely calling an Android standard recording interface to drive equipment to record.
The audio input control method provided by the embodiment of the invention has the following advantages:
1. for application developers (App 1 and App2 in the schematic diagram 5), Android standard recording standard interfaces (AudioRecord) can be used, so that development cost is greatly reduced (namely, customized private interfaces of various hardware manufacturers do not need to be learned), and development efficiency is improved;
2. when the equipment customization development kit is installed, the recording channel to which the equipment customization software belongs is preferentially selected;
3. the method can support various recording devices, the APP and the recording devices are not bound, and the devices can be flexibly switched;
4. calling equipment customization development kit through middleware (MicSDK) to optimize the recording effect;
5. if the device customization package is not installed in the middleware (MicSDK), the Android standard recording interface is used for driving the device to record, and the device is used as a universal device.
