It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The audio output method provided by the embodiment of the application can be applied to an application environment shown in fig. 1. Where the device 102 may be coupled to a plurality of displays 104, the device 102 may send processed data to each display 104 for display or output via each display 104. The device 102 may be a computer device, for example, a terminal or a server, and if the device is a terminal, the device may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices, and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart air conditioners, smart vehicle devices, and the like. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. In the case of a server, the server may be implemented as a stand-alone server or as a server cluster including a plurality of servers. The display 104 may include a display screen, which may be a liquid crystal display screen or an electronic ink display screen.
In one embodiment, as shown in fig. 2, an audio output method is provided, and the method is applied to the device 102 in fig. 1 for illustration, and the method may include the following steps:
s202, acquiring a mono audio code stream corresponding to each display connected with the device.
The mono channel refers to a sound channel, and generally refers to a process of uniformly recording audio signals from different directions after mixing, and then playing back the audio signals by a sound box. The audio code stream refers to an audio signal obtained after signal analysis, encoding and decoding, and the like. The audio signal is processed into the code stream and then processed into the mono audio code stream, so that the calculation amount of data can be reduced in the follow-up process, and the processing efficiency of the audio signal is improved.
Specifically, the device may control to display specific application software on each display, and then collect audio signals generated by the application software on each display in the running process, so as to obtain audio signals corresponding to each display, and process the audio signals of each display into a mono audio code stream, so as to obtain a mono audio code stream corresponding to each display.
S204, generating target audio code streams of the displays according to the mono audio code streams corresponding to the displays.
In this step, after obtaining the mono audio code streams generated by the application software on each display, the device takes one display as an example, and generally, multiple application software may be simultaneously run on the display, and each application software may generate a mono audio code stream, so that the display corresponds to multiple different mono audio code streams, so that the device can obtain multiple different mono audio code streams corresponding to the display; and then, the device can select one of the plurality of mono audio code streams corresponding to the display as the target audio code stream corresponding to the display, or can comprehensively process the plurality of mono audio code streams corresponding to the display to obtain the target audio code stream corresponding to the display.
The target audio code streams of other displays can be obtained by processing in this way, and will not be described here again.
S206, determining target channels corresponding to the target audio code streams from candidate channels of the equipment, and outputting the target audio code streams by adopting the target channels corresponding to the target audio code streams.
In this step, the device may include two or more candidate channels, and generally, each candidate channel is different, and the candidate channels are channels existing in the device, that is, sound playing channels, so that different sound outputs can be performed without modifying hardware of the device, thereby reducing hardware cost of the device.
In addition, as an alternative embodiment, when determining the target channel corresponding to each target audio code stream from the candidate channels of the device, the target channel corresponding to each display may be determined from the candidate channels of the device according to each target audio code stream and a preset correspondence, and each target channel may be determined as the target channel corresponding to each target audio code stream; wherein the correspondence includes a correspondence between a display and candidate channels of the device.
That is, a correspondence between the display and the candidate channels of the device may be pre-established, where the correspondence may include identifiers of multiple displays and their corresponding candidate channels, and after the target audio code streams of each display are obtained, the candidate channels may be matched to the candidate channels under the corresponding identifiers through the identifiers of the displays in the correspondence, and the candidate channels are determined to be the target channels corresponding to the display, that is, the target channels corresponding to the target audio code streams of the display, so that the target audio code streams corresponding to each display may be output by adopting the target channels corresponding to the target channels, and different sounds corresponding to each display are output by adopting different channels, thereby achieving the purpose of multi-screen iso-sound.
Taking a vehicle-mounted multi-screen scene as an example, assuming that a main driving position is provided with a display A, and a plurality of passenger positions except the main driving position are respectively provided with a display B, wherein the number of the displays B is more than or equal to 1, in order to realize that the sounds played by the display A and the display B are different, the sound of the display A can be controlled by a vehicle-mounted terminal to be output by adopting a first candidate sound channel of the vehicle-mounted terminal, and the sound of the display B can be output by adopting a second candidate sound channel of the vehicle-mounted terminal, so that multi-screen abnormal sound is realized, the hardware of the vehicle is not required to be improved, and the hardware cost of equipment is not increased.
In the audio output method, the target audio code streams of the displays are generated by acquiring the mono audio code streams corresponding to the plurality of displays connected with the device, according to the mono audio code streams corresponding to the displays, the target channels corresponding to the target audio code streams are determined from candidate channels of the device, and the target audio code streams are output by adopting the target channels corresponding to the target audio code streams. In the method, the target audio code stream generated by the mono audio code stream of each display can be output through the corresponding target channel determined from the candidate channels of the equipment, so that different sounds corresponding to each display are realized and output.
The foregoing embodiment has mentioned that the corresponding target audio code stream may be generated by a mono audio code stream of each display, and the following embodiment describes one possible implementation of the process in detail.
In another embodiment, another audio output method is provided, and the step S204 may include the following steps based on the above embodiment:
and mixing one or more mono audio code streams corresponding to the displays aiming at each display to generate a target audio code stream of each display.
In this step, referring to fig. 3, taking a display as an example, it is assumed that the display corresponds to 1 to N mono audio code streams, where N may be any positive integer greater than or equal to 1. After the mono audio code stream 1, the mono audio code stream 2 to (N-1) and the mono audio code stream N are obtained, the 1 to N mono audio code streams can be input into an audio mixer for audio mixing processing to obtain a mono audio code stream, namely, the target audio code stream corresponding to the display is obtained. For other displays, the audio mixing process can be performed in this way to obtain respective corresponding target audio code streams.
It should be noted that, if the number of mono audio code streams corresponding to the display is one, the one mono audio code stream may be input into the audio mixer for mixing processing, so as to obtain one audio code stream.
In addition, the audio mixer described above is a device for processing audio, and may be a software-type audio mixer, and the mixing process may be to mix a digital audio file with a line input audio signal or the like and then synthesize a separate digital audio file.
In this embodiment, by performing audio mixing processing on one or more mono audio code streams corresponding to each display, a target audio code stream of each display is generated, so that sound corresponding to the display can more conform to the audiovisual experience of human ears, and the auditory experience of a user is improved.
The foregoing embodiment refers to the fact that the device may acquire a mono audio code stream corresponding to each display, and the following embodiment describes one possible implementation of this process in detail.
In another embodiment, another audio output method is provided, and based on the above embodiment, as shown in fig. 4, the step S202 may include the following steps:
S302, acquiring audio files corresponding to each display connected with the equipment.
The audio signals generated during the running process of the specific application software displayed on each display can be stored in the form of audio files, so that the device can obtain the audio signals generated by the application software displayed on each display by acquiring the audio files. For the audio signals generated by the plurality of application software on each display, each application software can correspond to one audio file, and the plurality of application software of one display can also commonly correspond to one audio file.
For the storage format of the audio file, MP3, AAC, WAV, WMA, CDA, FLAC, M4A, MID, etc. may be included. Wherein, MP3 English is fully called: moving Picture Experts Group Audio Layer III, chinese is fully called: the dynamic image expert compresses the standard audio layer 3; AAC english is fully called: advanced Audio Coding, chinese is fully called: advanced audio coding; WAV Chinese is fully called: a waveform sound file; WMA english is fully called: windows Media Audio, chinese is fully called: microsoft audio format; CDA english is fully: CD track, chinese is fully called: track index format; FLAC English is fully called: free Lossless Audio Codec, chinese is fully called: lossless audio compression coding; the M4A Chinese is fully called: extension of the file of the MPEG-4 audio standard; MID english is fully called: musical Instrument Digital Interface, chinese is fully called: a digital interface for a music device.
Specifically, the device controls to display specific application software on each display, and then the device obtains audio files corresponding to each display by collecting audio files corresponding to audio signals generated by the application software on each display in the running process, wherein each display generally corresponds to different audio files.
The audio files corresponding to each display are different, and the storage formats of the audio files can be different, or the storage information in the audio files can be different. In addition, the storage formats of the audio files corresponding to each display may be the same or different, and if one display corresponds to a plurality of audio files, the storage formats of the plurality of audio files may be the same or different, so that the storage of audio signals meeting various storage formats can be diversified, and the applicability of the audio output method is improved.
S304, encoding and decoding are carried out on each audio file, and initial audio code streams corresponding to each display are determined.
In this step, the storage formats of the general audio files may be different, and after the audio files corresponding to each display are obtained, the initial audio code stream corresponding to each display may be obtained by performing codec processing, that is, encoding processing, decoding processing, and the like, on each audio file. The converted audio code stream can be used in each processing process of the subsequent audio output without format conversion, so that the audio output efficiency can be improved.
S306, determining a mono audio code stream corresponding to each display according to the initial audio code stream corresponding to each display.
In this step, after the initial audio code stream corresponding to each display is obtained, the initial audio code stream includes at least one of an audio code stream of a mono mode, an audio code stream of a plurality of independent channel modes, an audio code stream of a stereo mode, and an audio code stream of a joint stereo mode as an alternative embodiment. The following describes how to determine a mono audio stream when the initial audio stream is these several cases:
as an alternative embodiment, if the initial audio code stream includes an audio code stream in a mono mode, the audio code stream in the mono mode corresponding to the display may be used as the mono code stream corresponding to the display. If the initial audio code stream corresponding to a display is the audio code stream in the mono mode, the device only performs encoding and decoding processing on the audio file corresponding to the display, and directly uses the obtained audio code stream as the mono audio code stream corresponding to the display without any processing.
As an alternative embodiment, if the initial audio code stream includes a plurality of audio code streams in independent channel modes, an audio code stream in an independent channel mode may be determined from the plurality of audio code streams in independent channel modes as a mono code stream corresponding to the display. The audio code streams of the multiple independent channel modes corresponding to the general display are identical, so after the audio code streams of the multiple independent channel modes corresponding to one display are obtained, the device only performs encoding and decoding processing on the audio file corresponding to the display, and the obtained audio code streams can be taken as the mono audio code stream corresponding to the display.
As an alternative embodiment, if the initial audio code stream includes an audio code stream in stereo mode or an audio code stream in joint stereo mode, then data processing is performed on the audio code stream in stereo mode or the audio code stream in joint stereo mode, and the processed audio code stream is used as a mono audio code stream corresponding to the display.
In the case that the display corresponds to an audio code stream in a stereo mode, the data of left and right channels stored in the stereo audio file in the stereo mode has strong correlation, and after coding and decoding the audio file, the device can weight and stack the data of two channels according to time sequence to form one channel as a mono audio code stream; other extraction modes can be selected, and a single-channel audio code stream can be obtained, namely, a single-channel audio code stream corresponding to a display is obtained.
For the display, the audio code stream of the joint stereo mode corresponds to the mode, and the mode is only based on the stereo mode, so that the parts with strong correlation of the two channels are uniformly coded; after performing coding and decoding processing on the audio file, the device can generate a mono audio code stream in the same way as the stereo mode to obtain the mono audio code stream corresponding to the display.
In this embodiment, the device obtains the initial audio code stream after performing the encoding and decoding processing on the obtained audio files of each display, and obtains the corresponding mono audio code stream through the initial audio code stream, so that the mono audio code stream is obtained through the audio file encoding and decoding processing to obtain the mono audio code stream through the initial audio code stream, and the process of one-step parsing processing can make the mono audio code stream corresponding to each display obtained by the device more accurate, so that the subsequent audio output result is more accurate. In addition, the initial audio code streams of different modes are respectively processed to obtain the mono audio code streams in various modes, so that the audio code streams in various modes can be covered, the applicability of an audio output method is improved, and meanwhile, the obtained mono audio code streams can be more accurate through mode-division processing.
In the above embodiment, it is mentioned that the device may include a plurality of candidate channels, where as an alternative embodiment, the candidate channels of the device may include a left channel and a right channel, and the target audio code streams of at least two displays are different.
The left channel and the right channel are channels in a two-channel stereo system of the device, and can respectively output different audio code streams, and target channels corresponding to at least two displays in each display are different, for example, one display corresponds to the left channel, and the other display corresponds to the right channel; or a part of the display corresponds to a left channel and the other part of the display corresponds to a right channel; or a display corresponding to the right channel and a display corresponding to the left channel, thereby realizing multi-screen abnormal sound.
For example, continuing to take the above-mentioned vehicle-mounted multi-screen scene as an example, assuming that the main driving position has one display a, and a plurality of passenger positions except the main driving position each have one display B, and the number of the displays B is greater than or equal to 1, in order to realize that the sounds played by the displays a and B are different, the sounds of the displays a can be controlled by the vehicle-mounted terminal to be output by adopting the left channel of the vehicle-mounted terminal, and the sounds of the displays B are output by adopting the right channel of the vehicle-mounted terminal, where the display pictures and the output sounds of all the displays B are the same, but are different from the output sounds of the displays a, that is, multi-screen abnormal sounds are realized, so that the hardware of the vehicle is not required to be improved, and the hardware cost of the device is not increased.
Based on the left and right channels, in order to eliminate the influence of multi-screen abnormal sound on different users during output, sound interference is caused, and the influence can be eliminated by combining an audio output device in the following embodiments.
In another embodiment, another audio output method is provided, and based on the above embodiment, as shown in fig. 5, the step of outputting each target audio code stream by using a corresponding target channel in S206 may include the following steps:
S402, determining an audio output device connected with a target channel on the device; the audio output device comprises two output terminals.
S404, respectively performing digital-to-analog conversion processing on each target audio code stream, and outputting the target audio code stream by adopting a corresponding output end.
The audio output device can be a wire plugging earphone or a Bluetooth earphone, and the two output ends are respectively right-side earphones.
Referring to fig. 6, assuming that the audio output device is a patch earphone, after obtaining the target channels corresponding to the target audio code streams of different displays, an interface end of the patch earphone may be inserted into an audio output port of the device, after the patch earphone is connected, digital-to-analog conversion processing may be performed on the target audio code streams of each display by the device, or other audio processing may also be performed, etc., after that, each converted target audio code stream may be output through two output ends corresponding to the patch earphone, for example, the corresponding target audio code stream of the first display (corresponding to the screen 1 in the figure) may be output through a left-side earphone, that is, the left-side earphone may be used by a user who views the first display (corresponding to the screen 2 in the figure), and the corresponding target audio code stream of the second display may be output through a right-side earphone, that is, the right-side earphone may be used by a user who views the second display. Different target channels are corresponding to different positions of the interface end of the plug wire earphone, and different target channels are corresponding to the left and right side earphone, so that different audio code streams can be output through two output ends of the plug wire earphone.
Referring to fig. 7, assuming that the audio output device is a bluetooth headset, the device needs to be provided with a bluetooth communication module (i.e. the bluetooth module in the figure), after obtaining target channels corresponding to target audio code streams of different displays, the device may be connected with the bluetooth communication module of the device through the bluetooth headset, and the remaining devices are the same as the above-mentioned plug wire headset, so that each converted target audio code stream may be output from two output ends corresponding to the bluetooth headset. For example, the corresponding target audio code stream of the first display may be output by the left-hand earphone, i.e. the left-hand earphone may be available to a user viewing the first display, and the corresponding target audio code stream of the second display may be output by the right-hand earphone, i.e. the right-hand earphone may be available to a user viewing the second display. The left and right side ear phones of the Bluetooth headset correspond to different target sound channels, so that different audio code streams can be output through two output ends of the Bluetooth headset.
In this embodiment, by determining the audio output device connected to the target channel on the device, and performing digital-to-analog conversion on each target audio code stream, outputting the audio code streams by using the output ends corresponding to the audio output device, so that different audio code streams are output by different output ends of the audio output device, the problem of interference caused by the sound of the users of multiple displays can be avoided, and the hearing experience of the users is further improved.
