Embodiment two

Referring to FIG. 2 , it shows a flow chart of the steps of an embodiment of a switching method of an audio playback mode according to the present invention, which may specifically include the following steps:

Step 201, when the mobile terminal is connected to an audio input device, acquire a user's selection operation on the corresponding audio playback device of the mobile terminal.

Step 202: Determine the target audio playback device according to the selection operation.

In the embodiment of the present invention, in order to enable different audio applications on the mobile terminal to select an audio playback device that implements the earphone, pre-package a general standard application program interface (Application Program Interface, API), and provide it to the audio application. Specifically, , you can escape the control command into a specified string, and then encapsulate the string into a simple API. Among them, an API can contain various control commands and parameter values, and there is a one-to-one correspondence between control commands and parameter values. Different control The commands correspond to different audio playback device switching commands, and different parameter values correspond to different audio playback devices. In the embodiment of the present invention, one way for the mobile terminal to determine the target audio application is to determine according to the user's selection; specifically, when it is determined that the mobile terminal is connected to an audio input device, the audio playback device selection box can be automatically popped up, and the audio playback device selection box can also be highlighted. The playback device selection button, so that the user can select the audio playback device that the user wants to play audio; after the user selects the audio playback device in the audio application, the audio application calls the API of the operating system according to the user's selection; the API that the operating system calls for the audio application By analyzing, the corresponding control instructions and parameter values can be analyzed, so as to determine the command issued by the audio application, that is, the instruction to switch the audio playback device; before the operating system executes the instruction issued by the audio application, it determines the user The selected audio playback device determines the audio playback device selected by the user as the target playback device.

Step 203, judging whether the audio playback device connected to the audio playback channel is the target audio playback device.

Step 204, switch the audio playback channel of the mobile terminal to connect with the target audio playback device.

If the embodiment of the present invention determines the target audio playback device when the audio recording function is not activated, then when the mobile terminal is connected to the earphone of the audio input device, the audio playback channel is automatically connected to the earphone, therefore, the currently connected audio playback device of the mobile terminal The device is an earphone; if the target audio playback device is determined during the audio recording process, the audio playback device currently connected to the mobile terminal is the audio playback device selected by the user last time; and the audio playback device selected by the user this time may be The audio playback device currently connected to the mobile terminal may not be the audio playback device currently connected to the mobile terminal. When the operating system of the mobile terminal executes the instruction to switch the audio playback device issued by the audio application, it first needs to determine the audio playback path of the mobile terminal. The currently connected audio playback device; if the audio playback device currently connected to the audio playback path of the mobile terminal is the target audio playback device, the mobile terminal maintains the connection status of the current audio playback path; if the audio playback path of the mobile terminal is currently connected to the audio If the playback device is not the target audio playback device, switch the audio playback path to connect with the target audio playback device. Specifically, referring to FIG. 3, FIG. 3 shows a schematic diagram of an audio playback path embodiment of the present invention. If the current DAC module is connected to the earphone through 2, when the target audio playback device is a built-in speaker, the DAC module will be connected to the earphone from the path 2Switch to channel 1 to connect to the built-in speaker amplifier so that the audio playback path is connected to the built-in speaker.

Step 205, start the audio recording of the audio application, and receive the second audio when the first audio is output to a preset time frame.

Step 206, when the target audio playback device is a built-in speaker of the mobile terminal, enable a preset anti-howling algorithm to process the second audio.

When the target audio playback device in the embodiment of the present invention is a built-in speaker, when the distance between the external audio input device and the built-in speaker is relatively close or in other circumstances, the phenomenon of howling will also occur, which greatly reduces the user experience; therefore, in order to To effectively eliminate howling, when it is determined that the target audio playback device is a built-in speaker, the preset anti-howling algorithm in the audio digital processing module in the mobile terminal can be turned on to prevent the second audio after receiving the second audio. Howling processing, wherein, the preset anti-howling algorithm is an algorithm for processing audio data, so as to prevent the phenomenon of howling from the sound played by the built-in speaker; and when it is determined that the target audio playback device is not a built-in speaker , when it can be judged whether the preset anti-howling algorithm is off, when the preset anti-howling algorithm is off, there is no need to turn on the preset anti-howling algorithm, when the preset anti-howling algorithm is When enabled, the preset anti-howling algorithm is prohibited. In the embodiment of the present invention, the second audio is recorded on the basis of the first audio, that is, when the audio recording function is turned on, the audio application outputs the first audio and plays it through the target audio playback device. After the first audio is played to the preset time frame, the user can record the second audio through the audio input device; wherein, the preset time frame is determined according to the first audio; in addition, according to the above, the user can select the audio playback device in two cases, one is Before the audio recording is started, the other is after the audio recording is started, during the recording process; for different situations, the corresponding preset time frames are different; in addition, for the latter case, after selecting the audio playback device at different time points, When continuing to start audio recording, the corresponding preset time frame is also different.

Specifically, the second audio enters the preamplifier through the audio input device, and then is collected by the analog-to-digital conversion module and output to the audio digital processing module. After the audio digital processing module receives the second audio, if the preset anti- Howling algorithm, then the preset anti-howling algorithm can be called to perform anti-howling processing on the received second audio; since the second audio includes the audio that the user wants to record and the audio played by the built-in speaker, it can be filtered processing and harmonic processing, remove the audio of the built-in speaker in the second audio, and at the same time enhance the fidelity of the audio that the user wants to record, and obtain the processed second audio. If the preset anti-howling algorithm is not enabled, it is only necessary to perform denoising processing on the received second audio to obtain a second audio with better effect.

Step 207: Synthesize the first audio output by the audio application and the second audio received by the audio input device to obtain a third audio.

Step 208: Output the third audio to the target audio playback device through the audio playback path for playback.

Starting from the preset time frame, after processing the received second audio, immediately synthesize the first audio and the processed second audio to obtain a third audio, and then pass through the audio playback channel to convert the third audio The audio is output to the target audio playback device. Since the second audio processing time and synthesis processing time are very short, when the third audio is played by the target audio playback device, the third audio heard by the user is basically real-time, and the third audio is not output after the audio recording starts. Before the audio, the first audio is output to the target audio playback module through the audio playback path, and the target audio playback module plays the first audio.

In addition, the audio application in the embodiment of the present invention may include the function of karaoke, and may also include other functions; when the user uses the audio application to perform karaoke, the first audio is the audio corresponding to the song accompaniment; the second audio is the user's singing voice corresponding audio. The user can also select the effect of the recorded second audio, such as KTV effect, recording studio effect, and the mobile terminal correspondingly performs the corresponding processing on the recorded second audio before synthesizing the first audio and the second audio according to the effect selected by the user. Effect processing to enhance the user experience.

In addition, in addition to outputting the third audio to the target audio playing module, the mobile terminal also outputs the third audio to the recording module, and before synthesizing the third audio, outputs the first audio to the recording module.

In the embodiment of the present invention, when the target audio playback device is a built-in speaker, the anti-howling algorithm is started; after receiving the second audio, the second audio is processed using the preset anti-howling algorithm to ensure that the first audio played through the built-in speaker The three audios do not produce howling; then the first audio and the processed second audio are processed, and the processed audio is output to the audio playback device selected by the user, so that the synthesized audio is processed by the audio device selected by the user Playing realizes that the mobile terminal can switch the audio playback channel to the audio playback device selected by the user according to the user's selection, so as to use the audio playback device selected by the user to realize the ear return.
