Detailed Description
The embodiment of the application provides an autonomous audio source switching method, computing equipment and storage medium based on an Android system, which meet the requirement of dynamically switching audio sources by a host or a photographer under the condition of not modifying third party application.
In the prior art, the Android system only supports the application in calling AudioRecord to specify the audio source, and only supports a plurality of specific audio sources. The existing audio source switching scheme needs to modify application codes, and the steps of switching audio sources are as follows: the recording is stopped, then the audio source of the appointed recording is switched, and the recording is started again. The above steps not only have unsmooth switching flow, but also can not realize one-key switching.
The method for switching the autonomous audio source based on the Android system provided by the embodiment of the application is further described with reference to the accompanying drawings,
fig. 1 shows that the application discloses an autonomous audio source switching method based on an Android system, which comprises the following steps:
s11, acquiring an audio source switching request, wherein the request comprises target audio channel information;
the audio source switching request can be sent out by a user (a host or a photographer) according to switching requirements in the live broadcast all-in-one machine through an interactive interface, system prompt and proprietary client interaction, or can be automatically switched according to the current hardware inspection of the live broadcast all-in-one machine, such as sequential switching, random switching and the like.
By way of example, the audio source switching request may be implemented through an interactive process as in fig. 2, and referring to fig. 2, an audio source switching setting interface is generated according to the audio source switching request;
s21, when an audio source switching request is received, the audio source switching request faces to audio sources of a plurality of audio and video platforms;
the live broadcast all-in-one machine generally has a plurality of audio hardware input ports, such as 'AUXIN', 'Micphonein', 'HDMIN', 'USBIN', and the like. While various audio hardware input ports may be implemented through connections to a digital audio processor (DSP), not limited thereto.
When a third-party live broadcast application, such as 'panning A live broadcast', 'shaking Y live broadcast', 'small H book live broadcast', is opened, the suspension window can be operated to set the current use of the audio source.
S22, generating a set floating window corresponding to the request of the audio source switching;
of course, the floating window is only one interactive display mode in response to a user's audio source switching needs, and reference to FIG. 3 is not intended as a limitation of the present application.
And receiving an audio source setting instruction input by a user through the audio source switching setting interface through an audio input module, and setting the audio path and configuring the audio through an audio processing module.
S23, receiving a setting instruction of a user for switching the audio source by utilizing the setting floating window, and storing the configuration selected by the user in the setting floating window.
The floating window may be in the form of an embedded application that listens to audio port plug-in or plug-out signals, ensuring that the switchable audio source is device-specific. When the device corresponding to the audio source is available, namely: when the user (the anchor or the photographer) performs switching selection, the floating window provides a set selection button or a sliding block to collect options of the user (the anchor or the photographer), and the selection data of the user is obtained and stored.
If the corresponding setting of a platform is next time the user has a switching requirement to the audio source corresponding to the platform, the corresponding selection interaction process is directly invoked, and the operation is simplified.
S12, analyzing the request to obtain audio path parameters and audio configuration information;
the analysis of the request can be completed through a virtual or entity module, and as an example, an Audio Hal module can be selected to be responsible for realizing the interface control functions of the Audio channels of different hardware platforms.
S13, switching the current audio source to the target audio channel according to the audio path parameters;
according to the Audio path parameters, the switch to the corresponding Audio path is switched, for example, a host or a photographer uses a live broadcast room of 'panning A live broadcast', the host wants to switch to 'panning C live broadcast' for recording, a recording channel needs to be switched from USB IN to HDMI IN, an Audio Hal module is selected to switch on the switch of HDMI IN according to the Audio path parameters, the Audio recording switching of 'panning C live broadcast' is supported, and meanwhile, the access of hardware is completed through a digital Audio processor (DSP).
And S14, starting the audio service in the current target audio channel according to the audio configuration information.
IN the above step, the recorded data source is switched from USB IN to HDMI IN, and a digital audio processor (DSP) is usually connected with a line IN/mic IN of a built-IN Codec, and analog signals are sampled through an ADC. The audio input of HDMI is typically a digital signal, which can be processed directly by the DSP, i.e.: the function of the audio channel of HDMI is enabled.
Referring to fig. 4, for parsing the request in S12, audio path parameters and audio configuration information are obtained, optionally, by the following steps:
s41, acquiring audio path parameters and the audio configuration information by adopting an audio path configuration analyzer;
the Audio path configuration parser may be preferably an Audio Hal module in the above embodiment, or a parser configured in another module may be selected, and is not limited. The configuration of the audio path is analyzed, and the configuration command is converted into a corresponding path switching configuration command.
S42, the audio path parameters are issued to an audio processing module;
the audio processing module may select a digital audio processor (DSP) in the above embodiment, or may select other integrated audio conversion processors.
And issuing the audio path parameters from the audio path configuration analyzer to the DSP.
S43, the audio processing module sets the switch of the target audio channel according to the audio path parameters, and completes audio configuration according to the audio configuration information.
For example, the DSP switches the audio path switch according to the audio path parameters and performs relevant configuration of the sound effects by selectively interacting with the user in the form of a floating window of the client or the like. The DSP switches to a new audio path based on the audio path parameters, namely: and opening a switch of the target audio channel.
Preferably, after switching to the target audio channel, smoothing processing is performed when switching from playing the preceding audio data to playing the current audio data.
When switching from the current audio source to the new audio source, the joint of the two paths of audio data may have abrupt volume changes, and noise caused by direct splicing of the audio data is needed to be smoothed.
Preferably, the smoothing process may enable DSP driver for splicing and volume fade-In by inserting driver out (100 ms) and driver In (100 ms) data between the two audio data. From the interface angle output to the user, the faceout works, the volume is set to 0, a 100ms volume fade-out curve can be generated on the interface, the DSP turns on a switch for switching the audio channel, the volume is recovered, the facein works, and a 100ms volume fade-in curve can be generated on the interface. The display form is not limited, or can not be displayed according to the play setting of the live broadcast integrated machine.
