In view of the above problems, the present application provides a method for outputting multiple audio streams, and the following describes embodiments of the present application in detail.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a method for outputting multiple audio streams in an electronic device according to an embodiment of the present disclosure; as shown in the figure, the multi-channel audio stream output method includes:
the audio output module may include any one of an earphone, a sound box, and a pair of earphones, and a speaker carried by the electronic device itself, and the like, which are built in the electronic device or connected to the electronic device to play audio content of the electronic device.
the at least two audio streams in the matching strategy correspond to at least 2 audio output modules, and it can be seen that the matching strategy does not output the multiple audio streams through one audio output module in a sound mixing manner under the condition that multiple audio output modules are selected when the multiple audio streams are output.
And 203, the electronic equipment controls the audio output module to output the at least two audio streams according to the matching strategy.
It can be seen that, in the embodiment of the present application, when detecting an output request of at least two audio streams, an electronic device detects an audio output module that can be currently enabled, and then, when detecting that the number of the audio output modules is greater than or equal to 2, determines a matching policy between each audio stream and the audio output module, and finally, controls the audio output module to output the at least two audio streams according to the matching policy. Therefore, the electronic equipment can determine the matching strategy according to the detected multi-channel audio and the plurality of audio output modules, and output multi-channel audio signals through the audio output modules according to the matching strategy, so that the situation that the multi-channel audio is output only through one audio output module to cause audio confusion is avoided, the multi-channel audio signals can be output from different paths, the diversified experience requirements of users are met, the functionality and the applicability are expanded, and the operation process of executing the multi-channel audio output is simplified.
In one possible example, the electronic device determines a matching policy between each audio stream and the audio output module, including: the electronic equipment acquires the source information of each audio stream in the at least two audio streams; acquiring a corresponding relation set between preset source information and audio output modules, and screening N audio streams in the at least two audio streams and an audio output module corresponding to each audio stream in the N audio streams according to the corresponding relation set, wherein the source information of each audio stream is the source information in the corresponding relation set, the audio output module corresponding to each audio stream in the N audio streams is the audio output module in the corresponding relation set, and N is a natural number; determining a matching relationship between M audio streams and audio output modules which are not screened out in the audio output modules which can be started, wherein the M audio streams are the audio streams which are not screened out in the at least two audio streams, and M is a natural number; and generating the matching strategy according to the corresponding relation of the N paths of audio streams and the matching relation of the M paths of audio streams.
The source information of the audio stream can be divided according to a certain website or certain software, and the corresponding relation set between the source information and the audio output module can be adjusted according to the use habit of a user or adjusted through manual input of the user.
Optionally, if the multiple audio streams and the multiple audio modules all belong to a device having a matching relationship with the corresponding relationship, N is the number of the audio streams to be output, and M is 0; if the multi-channel audio stream and the plurality of audio modules do not belong to the equipment with the corresponding relationship and the matching relationship, N is 0, and M is the number of channels of the audio stream to be output;
for example, when the electronic device detects that a user often plays music of a certain software through a certain audio output module device, the electronic device pops up the corresponding relationship between the audio output module and the software, and stores the corresponding relationship into the corresponding relationship set after the user determines the corresponding relationship.
In this example, the electronic device may first screen out a part of the audio streams and the audio output modules having a matching relationship with the multiple audio output modules through a preset corresponding relationship, and then match the audio streams and the audio output modules not having the matching relationship, which simplifies the complexity of the matching process and accelerates the matching speed.
In one possible example, M is a positive integer, the audio output modules that are not screened out in the enabled audio output modules include K audio output modules, and K is a positive integer; the electronic device determining a matching relationship between the M audio streams and the audio output modules that are not screened out of the audio output modules that can be enabled, includes: determining the priority of each audio stream in the M audio streams, and sequencing the M audio streams according to a preset sequence of the priorities to obtain an audio stream sequence; acquiring parameter information of the K audio output modules, and determining audio output module sequences of the K audio output modules according to the parameter information; and determining the matching relation according to the audio stream sequence and the audio output module sequence.
In this example, the electronic device correspondingly sequences the audio stream and the audio output module to generate a sequence, and determines a matching relationship between the audio stream and the audio output module according to the sequence of the audio stream and the audio output module, so that matching rationality is improved.
In one possible example, the electronic device determining the matching relationship according to the sequence of audio streams and the sequence of audio output modules includes: if M is less than or equal to K, the electronic equipment configures one audio output module in the audio output module sequence for each audio stream of the audio stream sequence, the audio output modules corresponding to any two audio streams are different from each other, and the priority ordering relationship of the any two audio streams in the audio stream sequence is matched with the ordering relationship of the 2 audio output modules corresponding to the any two audio streams in the audio output module sequence; if M > K, the electronic device configures one audio output module in the audio output module sequence for each audio stream of the audio stream sequence, wherein K-1 audio streams sequenced at the front in the audio stream sequence correspond to K-1 audio output modules sequenced at the front in the audio output module sequence one by one, and the priority sequencing relation of any one audio stream in the K-1 audio streams in the audio stream sequence is matched with the sequencing relation of 1 audio output module corresponding to any one audio stream in the audio output module sequence; and the audio streams in the audio stream sequence except the K-1 audio streams sequenced at the front correspond to the last audio output module in the audio output module sequence.
And when M is less than or equal to K, the electronic equipment can match one audio output module with an unexpected audio stream in the multi-channel audio streams from high to low or from low to high according to the audio stream sequence and the audio output module sequence. And under the condition that M > K, sequentially matching the front K-1 or rear K-1 audio streams in the audio stream sequence with the front K-1 audio output modules in the audio output module sequence according to specific conditions, and matching the last audio output module in the whole audio output module sequence for the remaining unmatched audio streams in the audio stream sequence.
For example, assuming that M is 5 and N is 10, the audio stream sequence is aligned first and matched with the audio output module sequence first, and the audio stream sequence is aligned second and matched with the audio output module sequence second, until the audio stream sequence is aligned fifth and matched with the audio output module sequence fifth; assuming that M is 10 and N is 5, the audio streams with the first four audio stream sequences are matched with the audio output modules with the first four audio stream sequences in the audio output module sequence one by one, and the audio streams with the audio stream sequences five to ten are all matched with the audio output module with the fifth audio stream sequence.
Therefore, in the example, the electronic device flexibly adjusts the matching strategy according to the actual situation, so that each audio stream has a matched audio output module, the functionality of the electronic device is expanded, and the requirements under different scenes are met.
In one possible example, the electronic device determines a priority of each of the M audio streams, including: the electronic equipment acquires the display area of the display content associated with each audio stream in the M audio streams on the display screen of the electronic equipment; and determining the priority of each audio stream in the M audio streams according to the area associated with each audio stream in the M audio streams.
The priority of the audio stream is determined according to the display area associated with each audio stream, and the priority of the audio stream is higher when the associated display area is larger
Therefore, in this example, the degree of importance of the user to the audio stream is determined according to the screen splitting condition of the user, and then the priority of the audio stream is determined, so that the intelligence of the electronic device is improved, and the steps of the multi-channel audio output process are simplified.
In one possible example, the electronic device determines a priority of each of the M audio streams, including: the electronic equipment divides the M paths of audio streams into a first audio stream set and a second audio stream set according to audio types, wherein the audio types comprise a shared audio type and a private audio type, the first audio stream set corresponds to the shared audio type, and the second audio stream set corresponds to the private audio type; and determining the priority of each audio stream in the first audio stream set according to a first priority determination strategy, and determining the priority of each audio stream in the second audio stream set according to a second priority determination strategy, wherein the priorities determined by the first priority determination strategy are all lower than the priorities determined by the second priority determination strategy.
The electronic equipment divides the M audio streams into two categories, namely a sharing type and a private type through the audio type, the priority of the private type audio stream is greater than that of the sharing type audio stream, and different strategies are adopted for further determining the priority of the same type audio stream. The audio stream of the shared audio type comprises the content information of the audio stream, such as a television series, a movie, music and a recording trailer, and the audio stream of the private audio type comprises the content information of the audio stream, such as conversation voice and instant messaging voice. The priority of the sharing type and the priority of the privacy type can be adjusted by the user through setting.
Therefore, in this example, the electronic device first divides the audio stream into two types according to the content type, and then determines the priority of the audio stream in the two types, so that the intelligence of the electronic device is improved, and the steps of the multi-channel audio output process are simplified.
In one possible example, the electronic device determines the priority of each audio stream in the first set of audio streams according to a first priority determination policy, including: the electronic device determining a frequency of use of an application associated with each audio stream in the first set of audio streams; acquiring a preset first mapping relation set, wherein the mapping relation set comprises a corresponding relation between the use frequency and the priority of a first type application, and an audio stream of the first type application is the shared audio type; and determining the priority of each audio stream in the first audio stream set according to the use frequency of the application associated with each audio stream and the first mapping relation set.
Optionally, determining the priority of each audio stream in the second audio stream set according to a second priority determination policy, and determining the use frequency of an application associated with each audio stream in the second audio stream set; acquiring a preset second mapping relation set, wherein the mapping relation set comprises a corresponding relation between the use frequency and the priority of a second type of application, and an audio stream of the second type of application is the private audio type; and determining the priority of each audio stream in the second audio stream set according to the use frequency of the application associated with each audio stream and the second corresponding relation set.
Therefore, in this example, the electronic device performs priority ranking on the audio streams in the same type according to the use frequency of the application associated with each audio stream, so that the intelligence of the electronic device is improved, and the steps of the multi-channel audio output process are simplified.
In one possible example, the parameter information includes a rated output power and a connection mode, and the electronic device determines an audio output module sequence of the K audio output modules according to the parameter information, including: the electronic equipment determines the first priority of each audio output module in the K audio output modules according to the rated output power; determining a second priority of each audio output module according to the connection mode, wherein the connection mode comprises a wireless connection and a wired connection, and the priority corresponding to the wireless connection is greater than the priority corresponding to the wired connection; determining the configuration priority of the audio output module according to the first priority and the second priority; and determining the audio output module sequence of the K audio output modules according to the configuration priority.
For example, the electronic device may read a preset corresponding relationship between an output power value and priority values according to the rated output power to determine first priority values of the K audio output modules, determine second priority values according to the wireless connection and the wired connection, add the first priority values and the second priority values to obtain configuration priority values, and generate an audio output module sequence of the K audio output modules according to the configuration priority values.
Therefore, in this example, the electronic device determines the audio output module sequences of the K audio output modules according to the rated output powers and the connection modes of the K audio output modules, so that the intelligence of the electronic device is improved.
In one possible example, the electronic device determines a matching policy between each audio stream and the audio output module, including: the electronic equipment outputs a control interface, wherein the control interface comprises the at least two audio streams and an audio output module which can be started; acquiring the setting operation of a user for the control interface; and determining the matching strategy according to the setting operation.
Therefore, in the example, the electronic device determines the matching strategy through interaction, so that the functionality and the practicability are expanded, and various requirements under a multi-channel audio output scene are met.
Optionally, after determining the matching policy between each audio stream and the audio output module, before controlling the audio output module to output the at least two audio streams according to the matching policy, the electronic device displays the matching policy on a display screen of the electronic device in a pop-up window form, where the pop-up window includes a confirmation option and a denial option; receiving feedback information of a display screen; if the feedback information is confirmation information, detecting a first number of audio output modules which are not matched with the currently-enabled audio output modules, if the first number is larger than 0, displaying the first number of audio output modules and the at least two paths of audio streams on a display screen, and receiving a first matching strategy of the first number of audio output modules and the at least two paths of audio streams; adding the first matching strategy to the matching strategy; if the feedback information is negative information, displaying the currently enabled audio output module and the at least two paths of audio streams on a display screen, and receiving a second matching strategy of the currently enabled audio output module and the at least two paths of audio streams; and updating the content of the matching strategy into the content of the second matching strategy.

and 308, controlling the audio output module to output the at least two audio streams by the electronic equipment according to the matching strategy.
It can be seen that, in the embodiment of the present application, when detecting an output request of at least two audio streams, an electronic device detects an audio output module that can be currently enabled, and then, when detecting that the number of the audio output modules is greater than or equal to 2, determines a matching policy between each audio stream and the audio output module, and finally, controls the audio output module to output the at least two audio streams according to the matching policy. Therefore, the electronic equipment can determine the matching strategy according to the detected multi-channel audio and the plurality of audio output modules, and output multi-channel audio signals through the audio output modules according to the matching strategy, so that the situation that the multi-channel audio is output only through one audio output module to cause audio confusion is avoided, the multi-channel audio signals can be output from different paths, the diversified experience requirements of users are met, the functionality and the applicability are expanded, and the operation process of executing the multi-channel audio output is simplified.
