Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
References herein to "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.
Referring to fig. 1, a flowchart of an audio playing method according to an exemplary embodiment of the present application is shown. The embodiment of the application is illustrated by taking the application of the method to the terminal as an example, and the method comprises the following steps:
step 101, receiving an audio playing instruction, where the audio playing instruction is used to instruct to play the target audio.
The audio playing instruction may be that the terminal receives a click operation of a user on a target playing control, where the target playing control is a playing control corresponding to the target audio; or in the audio play queue, playing the audio to the target audio according to a preset play sequence, that is, receiving a play instruction of the target audio, where the preset play sequence may be a play sequence such as random play, sequential play, single-song circulation, etc., which is not limited herein.
In one possible implementation manner, when the user clicks the target playing control corresponding to the target audio, the terminal receives a playing instruction of the target audio correspondingly.
Step 102, in response to the local audio file corresponding to the target audio being stored, and the first sound quality corresponding to the local audio file being lower than the target sound quality, obtaining the cached audio file corresponding to the target audio.
The local audio file may be stored in a local folder of the music application program after the user clicks the download control before the terminal receives the audio playing instruction.
The target tone quality is set by the user, or by default by the music application program, and may be standard tone quality, high-quality tone quality, lossless tone quality, or the like, which is not limited in this embodiment.
In one possible implementation manner, when the terminal receives a play instruction of the target audio, it is first determined whether a local audio file corresponding to the target audio is stored, and whether the first sound quality corresponding to the local audio file is lower than the play (listening) sound quality currently set by the user (i.e. the target sound quality), if so, whether the target audio has a cached audio file with a higher sound quality is continuously determined.
Schematically, if the target tone quality is high quality tone quality, and the first tone quality corresponding to the local audio file is standard tone quality, since the standard tone quality is lower than the higher tone quality, in order to avoid the phenomenon that the terminal directly plays while buffering according to the target tone quality, if the target audio file has a higher tone quality buffered audio file, the terminal needs to continuously judge whether the target audio file has a higher tone quality.
Optionally, if the first tone quality is not lower than the playing tone quality (i.e. the target tone quality) currently set by the user, in order to avoid that the terminal plays while buffering according to the target tone quality, the target audio may be directly played according to the local audio file.
And step 103, in response to the existence of the cached audio file, and the second tone quality corresponding to the cached audio file is higher than the first tone quality, carrying out integrity check on the cached audio file to obtain a check result.
The cached audio file may be obtained by caching the target audio when the terminal plays the target audio before playing the last song, or may be obtained by pre-caching the target audio when playing other audio in the playing queue.
In one possible implementation manner, if the terminal determines that the target audio has the local audio file, but the first tone quality corresponding to the local audio file is lower than the target tone quality, it is first determined whether the target audio has the cached audio file with higher tone quality, and if the target audio has the cached audio file with higher tone quality, the integrity check needs to be performed on the cached audio file, so that play jam caused by incomplete cached audio is avoided.
Alternatively, the verification result may be that the cached audio file is complete or that the cached audio file is incomplete.
Optionally, the second tone quality corresponding to the buffered audio file may be the same as, higher than, or lower than the target tone quality.
And 104, determining a target audio file from the cached audio file and the local audio file according to the verification result.
In one possible implementation manner, if the cached audio file is complete, the cached audio file with the quality higher than the first tone quality is represented, at this time, the cached audio file may be determined as the target audio file for playing the target audio, which may avoid a playing jam phenomenon caused by the incomplete cached audio file, and may also consider the playing tone quality of the target audio.
Optionally, if the cached audio file is incomplete, it indicates that although the cached audio file with the quality higher than the first tone quality exists, the situation that the cached audio file is not cached is not completed exists, at this time, whether the cached audio file is used as the target audio file can be determined according to the actual situation of the network and the remaining amount of the cache, or the local audio file is directly used as the target audio file for playing the target audio, so that the playing smoothness of the target audio can be ensured.
Step 105, playing the target audio according to the target audio file.
In one possible implementation manner, after the terminal determines the target audio file corresponding to the target audio, the target audio can be played according to the target audio file.
In summary, in the embodiment of the present application, when the terminal receives the audio playing instruction for playing the target audio, if it is determined that the local audio file corresponding to the target audio is stored, and the first sound quality corresponding to the local audio file is lower than the target sound quality, it is determined whether the cached audio file higher than the first sound quality is stored; if the local audio file and the buffer audio file corresponding to the target tone quality do not exist, the audio playing method provided by the embodiment of the application can select the local audio file or the buffer audio file to play the audio, avoid playing the click phenomenon caused by playing the buffer audio when the network is poor, and improve the playing fluency of the target audio.
In a possible implementation manner, the buffered audio file corresponding to the target audio is obtained by pre-buffering before playing the target audio, for example, when playing the previous audio, the buffered audio file corresponding to the target audio is obtained by pre-buffering the target audio; or after the previous audio pre-caching is completed, pre-caching the target audio.
Referring to fig. 2, a flowchart of an audio playing method according to another exemplary embodiment of the present application is shown. The embodiment of the application is illustrated by taking the application of the method to the terminal as an example, and the method comprises the following steps:
in step 201, in response to the target audio having the pre-caching requirement, the target authority information corresponding to the target user account is obtained.
The target authority information may include whether the target user account has a play authority for the target audio (whether the target user account is a member account), or whether the target user account has a play authority for the target sound quality.
In a possible implementation manner, if there are multiple audio to be played in the audio play queue, when the previous audio buffer of the target audio is finished or the previous audio is playing, the target audio may be pre-buffered, before the target audio is pre-buffered, it is further required to determine whether the target audio has a pre-buffering requirement, for example, if the terminal does not store a local audio file and a buffered audio file corresponding to the target audio, the target audio needs to be pre-buffered, so that play katon may be avoided during playing; if the local audio file is stored in the terminal, but the sound quality corresponding to the local audio file is lower than the sound quality set by the current user, in order to improve the listening experience of the user, the target audio with higher sound quality needs to be pre-cached. And if the target audio has the pre-caching requirement, acquiring target authority information of the target user account number, and determining how to pre-cache the target audio.
Optionally, when the terminal obtains the target authority information corresponding to the target user account, the terminal may also obtain information corresponding to the target audio, for example, whether the target audio is a paid audio or a free audio, and whether the target audio needs payment or not for downloading.
Step 202, pre-caching the target audio according to the target authority information to obtain a cached audio file.
In one possible implementation manner, if the target authority information indicates whether the target user account has audio playing authority for the target audio and whether the target user account has audio playing authority for the target audio, the terminal needs to determine how to pre-cache the target audio by judging the target authority information, so as to obtain a cached audio file.
Illustratively, step 202 may include steps 202A and 202B, as shown in FIG. 3, on the basis of FIG. 2.
In step 202A, in response to the target permission information indicating that the target user account has the target audio playing permission and the target user account does not have the target tone quality playing permission, the target audio with the third tone quality is pre-cached to obtain the cached audio file, wherein the third tone quality is lower than the target tone quality and higher than the first tone quality.
In a possible implementation manner, if the terminal determines that the target user account has the target audio playing authority, it indicates that the target user account can cache the complete target audio, but the target user account does not have the playing authority of the target audio, and it indicates that the target user account does not have the listening authority of the target audio to the audio currently set by the user, then the target audio needs to be subjected to degradation caching, that is, the cached audio with the quality lower than that of the target audio is obtained, and the cached audio file with the third quality is obtained.
Optionally, if the target audio has a local audio file, but the first tone quality corresponding to the local audio file is lower than the target audio, if the target audio still needs to be pre-cached, the third tone quality must be higher than the first tone quality, and then the caching is necessary.
Schematically, the first tone quality corresponding to the local audio file is a standard tone quality, the target tone quality (tone quality set by the user) is a lossless tone quality, and if the target user account does not have a listening authority for the lossless tone quality, the target audio is degraded and buffered, then the third tone quality should be a high-quality tone quality, and the condition that the third tone quality is lower than the lossless tone quality and higher than the standard tone quality is satisfied.
Optionally, if the target audio does not have a local audio file and the target audio file is cached, degradation pre-caching is required for the target audio, and then the third tone quality may preferentially select a second lower tone quality, for example, if the target tone quality is lossless, the terminal may preferentially select a high-quality tone quality for pre-caching, and may also determine to select a lower tone quality in consideration of the current network state, for example, if the current network state is poor, may preferentially select a standard tone quality for pre-caching.
Step 202B, in response to the target authority information indicating that the target user account has the target audio playing authority and the target tone quality playing authority, pre-caching the target audio with the target tone quality to obtain a cached audio file.
In one possible implementation manner, if the terminal determines that the target user has the target audio playing authority and the target tone quality playing authority for the target audio, the terminal indicates that the target user can cache the target audio with the target tone quality, and at this time, the target audio can be pre-cached according to the target tone quality to obtain the cached audio file.
Optionally, if the target audio has a local audio file before the target audio is pre-buffered, and the local audio file corresponds to the first sound quality, the target sound quality should be higher than the first sound quality.
In another possible implementation manner, if the target authority information indicates that the target user account does not have the target audio playing authority and the target tone quality playing authority, the target audio may be subjected to the degradation buffering process, but since the target user account does not have the playing authority on the target audio, it indicates that the target audio cannot be completely buffered, and only partial buffering, for example, only 60s, can be achieved.
Optionally, if the target authority information indicates that the target user account does not have the target audio playing authority, but has the target tone quality playing authority, the target audio corresponding to the target tone quality may be pre-cached, and only partial caching may be implemented.
Step 203, receiving an audio playing instruction, where the audio playing instruction is used to instruct to play the target audio.
In step 204, in response to the local audio file corresponding to the target audio being stored, and the first sound quality corresponding to the local audio file being lower than the target sound quality, the cached audio file corresponding to the target audio is obtained.
And step 205, in response to the existence of the cached audio file, and the second tone quality corresponding to the cached audio file is higher than the first tone quality, performing integrity check on the cached audio file to obtain a check result.
The embodiments of steps 203 to 205 may refer to steps 101 to 103, and this embodiment is not described herein.
In response to the cached audio file being complete, the cached audio file is determined to be the target audio file, step 206.
In a possible implementation manner, when the terminal performs integrity check on the cached audio file with higher sound quality, if the integrity check passes, the cached audio file can be determined to be the target audio file if the target audio has the cached audio file with complete high sound quality, so that the playing smoothness of the song can be improved, and the user can hear the audio with higher sound quality.
In response to the cached audio file being incomplete, the local audio file is determined to be the target audio file, step 207.
In a possible implementation manner, if the cached audio file fails the integrity check, it indicates that the target audio does not have the complete cached audio file with high sound quality, and in the playing process of the target audio, it may be necessary to continue to cache, where when the network state is poor or when the network does not exist, the target audio may not be played smoothly, so, in order to improve the playing smoothness of the target audio, the local audio file may be determined as the target audio file, which is used for playing the target audio.
And step 208, playing the target audio according to the target audio file.
In one possible implementation, if the target audio file is a local audio file, playing the target audio according to the local audio file; and if the target audio file is the cached audio file, playing the target audio according to the cached audio file.
In this embodiment, before playing the target audio, the target audio is pre-cached according to the authority information corresponding to the target user account, so that when the target audio is played, the target audio has a higher quality of cached audio file, and the playing smoothness and playing tone quality of the target audio can be improved; in addition, through carrying out the integrality check to higher tone quality's buffer audio file to when the integrality check passes, adopt high tone quality's buffer audio file to play target audio, can guarantee that target audio has higher play tone quality, when the integrality check does not pass, adopt lower tone quality's local audio file to play target audio, can avoid the card of target audio in the broadcast in-process to stop the phenomenon, improve target audio's play smoothness.
In a possible implementation manner, before the target audio is cached, a pre-caching determination is further needed to determine whether the target audio needs to be pre-cached, for example, if the target audio has a higher quality local audio file or a cached audio file, that is, higher than the playing tone quality set by the current user, the pre-caching operation is not needed, so that unnecessary caching operation can be reduced, and thus occupation of the storage space of the terminal is reduced.
Illustratively, the determination of whether pre-buffering is needed may be made by referring to the following steps:
1. and determining that the target audio has a pre-caching requirement in response to the local audio file and the cached audio file corresponding to the non-stored target audio.
In one possible implementation manner, if the target user has not played the target audio before, correspondingly, the terminal does not store the cached audio file corresponding to the target audio; if the target audio is not downloaded before by the target user, the corresponding local audio file corresponding to the target audio is not stored in the terminal; after the terminal determines that the local audio file and the cached audio file corresponding to the target audio are not stored, in order to avoid a possible blocking phenomenon during the caching of the target audio, the target audio needs to be pre-cached in advance, that is, the target audio has a pre-caching requirement.
2. And in response to the local audio file corresponding to the target audio is stored, and the first tone quality corresponding to the local audio file is lower than the target tone quality, determining that the target audio has a pre-caching requirement.
In one possible implementation manner, if the terminal determines that the target audio has a local audio file and the target audio does not have a cached audio file, but the first sound quality corresponding to the local audio file is lower than the target sound quality, in order to improve the playing sound quality of the target audio, high-sound-quality pre-caching is required for the target audio, that is, the target audio has a pre-caching requirement.
Optionally, if the terminal determines that the target audio has a local audio file and the target audio has a cached audio file, but the sound quality corresponding to the cached audio file is also lower than the target sound quality, in order to improve the playing sound quality of the target audio, the target audio corresponding to the target sound quality needs to be pre-cached, that is, the target audio has a pre-caching requirement. The cached audio file may be cached when the user plays the target audio before.
In this embodiment, before the target audio is pre-cached, a pre-caching determination is performed to determine whether the target audio needs to be pre-cached, if so, the above pre-caching step is performed, and if not, the pre-caching is not needed, so that the pre-caching operation of the next audio is performed, unnecessary pre-caching operation can be avoided, the storage space of the terminal is saved, and meanwhile, the waste of the terminal traffic can be avoided.
In one possible implementation method, when the terminal determines that the cached audio file with higher tone quality is incomplete, if the time required for caching the cached audio file to be complete is longer, in order to avoid the playing of the blocking phenomenon, the local audio file is still used for playing the target audio, and if the time required for caching the cached audio file to be complete is shorter, the cached audio file can be used for playing, so that the playing tone quality of the target audio is improved. Therefore, the terminal can determine whether the target audio needs to be played according to the local audio file by determining the relation between the predicted buffer time length corresponding to the target audio and the buffer play time length.
Illustratively, step 207 may be replaced with steps 401 and 402, as shown in FIG. 4, based on FIG. 2.
In step 401, in response to the buffered audio file being incomplete, a buffered playing duration corresponding to the buffered audio file is determined.
The buffer playing time length refers to time required for playing according to the buffer audio file until the buffer audio file is finished, for example, the time length of the target audio is 4min, the buffer audio file is 3min, and the buffer playing time length is 3min.
In one possible implementation manner, if the cached audio file is incomplete, when playing according to a part of the cached audio file, the target audio is continuously cached at the same time, if the cached audio file is cached in the playing process of the cached audio file, the playing can be continuously performed according to the cached audio file, and if the cached audio file cannot be cached, the situation that a clamping phenomenon possibly occurs in the playing process is indicated, and the playing is required according to the local audio file, so that whether the target audio is played according to the local audio file can be determined by acquiring the playing time of the cached audio file.
In step 402, in response to the predicted buffer time being greater than the buffer play time, the local audio file is determined to be the target audio file, and the predicted buffer time is determined based on the current network cache and the remaining buffer amount of the buffered audio file.
The predicted buffering time period refers to a time period required for continuously buffering the target audio until the buffered audio file is completely buffered, for example, before playing the target audio, the time period of the buffered audio corresponding to the buffered audio file obtained by buffering is 2min, the time period of the buffered audio is 4min, and the time period required for continuously buffering from the 2min position until the complete buffered audio file is obtained may be 3min.
The predicted cache time length is related to the current network speed and the residual cache quantity of the cached audio file, and the current network speed and the predicted cache time length are in a negative correlation relationship, namely the lower the current network speed is, the longer the predicted cache time length is, otherwise, the higher the current network speed is, the shorter the predicted cache time length is; the residual buffer capacity of the buffered audio file and the estimated buffer time length form a positive correlation, namely, the larger the residual buffer capacity is, the longer the estimated buffer time length is, the smaller the residual buffer capacity is, and the shorter the estimated buffer time length is.
In a possible implementation manner, the terminal estimates the time length required for complete caching, i.e. the predicted caching time length, according to the current network cache and the residual caching amount of the cached audio file, for example, the predicted caching time length is 3min and is longer than the caching playing time length by 2min, which means that when the cached audio file is played, the target audio may not be cached and played at the same time, and in order to avoid the clamping phenomenon possibly caused by playing at the same time, the target audio may be played directly according to the local audio.
Optionally, if the predicted buffer time is less than the buffer play time, for example, the predicted buffer time is 1min and the buffer play time is 2min, it means that the target audio can be buffered in the process of playing the buffered audio file, and the target audio can be played according to the buffered audio file.
In this embodiment, by comparing the relationship between the predicted buffer time length and the buffer play time length, and determining the local audio file as the target audio file when the predicted buffer time length is longer than the buffer play time length, the audio play jam phenomenon caused by playing while buffering can be avoided, the audio play fluency is improved, if the predicted buffer time length is shorter than the buffer play time length, the target audio can be played according to the buffer audio file, and the play tone quality of the target audio is considered on the premise of ensuring the play fluency.
In one possible implementation manner, if the terminal receives a play instruction for the target audio, it determines that the local audio file and the cached audio file corresponding to the target audio are not stored, and at this time, the target audio needs to be played while cached according to the current network state.
Referring to fig. 5, a flowchart of an audio playing method according to another exemplary embodiment of the present application is shown. The embodiment of the application is illustrated by taking the application of the method to the terminal as an example, and the method comprises the following steps:
Step 501, an audio playing instruction is received, where the audio playing instruction is used to instruct to play the target audio.
The implementation of this step may refer to step 101, and this embodiment is not described herein.
Step 502, in response to the local audio file and the cached audio file corresponding to the non-stored target audio, obtaining a current network state, where the current network state includes at least one of a current network type and a current network speed.
In a possible implementation manner, when a terminal receives a playing instruction for a target audio, it determines that a local audio file and a cached audio file corresponding to the target audio are not stored, and at this time, when the target audio still needs to be played, the playing mode is to play the target audio while caching, and when the target audio is played while caching, the network state has a greater influence on the playing smoothness of the target audio, and the higher the cached tone quality is, the higher the requirement on the network state is, so in order to improve the playing smoothness of the target audio, the current network state needs to be acquired, so that the target audio with appropriate tone quality is selected according to the current network state to be cached and played.
The network type may be a wireless network or a mobile network, and the mobile network is related to a traffic package of the terminal.
In step 503, in response to the current network type being a wireless network, the target audio with the target tone quality is cached and played.
In a possible implementation manner, when it is determined that the current network type is a wireless network, it indicates that the user is in an indoor or wireless network environment, and the terminal network state is relatively stable, and at this time, the target audio with the target tone quality can be cached and played, so that the playing smoothness is not affected basically.
Optionally, in the process of caching and playing, the authority information of the user needs to be considered, for example, if the user does not have playing authority on the target audio, the target audio may not be played, for example, if the user does not have playing authority on the target tone quality, the user may still need to reduce the tone quality to cache and play.
In step 504, in response to the current network type being a mobile network, the target audio of a fourth tone quality is cached and played, the fourth tone quality being lower than the target tone quality.
In one possible implementation manner, if the current network type is a mobile network, which indicates that the user may be located outdoors or in an environment without a wireless network, the mobile network is greatly affected by the environment, and in this case, in order to reduce the traffic consumption of the user and maintain the playing stability, the target audio may be degraded, buffered, and played, where the fourth audio quality is lower than the target audio quality.
Illustratively, the target sound quality may be a high quality sound quality, and the fourth sound quality may be a standard sound quality.
And step 505, in response to the current network speed being higher than a preset network speed threshold, caching and playing target audio corresponding to the target tone quality.
The preset network speed threshold value can be preset by a developer or set by a user, and different network types can be considered for setting the network speed threshold value, for example, the network speed threshold value corresponding to the wireless network type can be higher than the network speed threshold value corresponding to the mobile network; or the preset network speed threshold value can consider different sound quality, namely, the higher the sound quality is, the higher the preset network speed threshold value is.
Illustratively, the preset net speed threshold may be 256KB/s.
In a possible implementation manner, when the terminal obtains the current network speed corresponding to the current network state, the current network speed is compared with a preset network speed threshold, if the current network speed is higher than the preset network speed threshold, for example, the current network speed is 500KB/s and is higher than the preset network speed threshold by 256KB/s, the current network state is better, and the audio with higher tone quality can be cached, and at this time, the audio is cached and played according to the target tone quality.
And step 506, in response to the current network speed being lower than the preset network speed threshold, buffering and playing the target audio corresponding to the fourth tone quality.
In a possible implementation manner, when the current network speed obtained by the terminal is lower than the preset network speed threshold, for example, the current network speed is 20KB/s and is far lower than the preset network speed threshold of 256KB/s, the current network state is poor, if the target audio with higher tone quality is still cached, a phenomenon of playing katon may occur, and the playing smoothness of the target audio is reduced, so that the target audio corresponding to the lower tone quality (i.e., the fourth tone quality) can be cached and played.
In this embodiment, when the terminal determines that the local audio file and the cache audio file corresponding to the target audio are not stored when the terminal plays the target audio, the target audio is played in a cache-while-play mode at this time; in addition, in order to ensure the playing fluency of the target audio, the target audio with which tone quality is cached and played can be determined according to the current network state of the terminal, when the network state is poor, the target audio with lower tone quality is cached and played, the fluency of audio playing can be ensured, when the network state is good, the target audio with lower tone quality is cached and played, and the tone quality of audio playing can be ensured while the fluency of audio playing is ensured.
In a possible implementation manner, if the terminal receives the playing instruction of the target audio, it is determined that the terminal does not store the local audio file, but stores the cached audio file, and at this time, the sound quality and the integrity corresponding to the cached audio file are not required to be concerned, and only the target audio needs to be played according to the cached audio file.
Optionally, the terminal may also determine whether to re-cache the corresponding tone quality of the cached audio file by comparing the relationship between the tone quality and the target tone quality, if the cached audio file is complete, the terminal may play the target audio according to the cached audio file preferentially without considering the relationship between the tone quality of the cached audio file and the target tone quality, so as to ensure smoothness of audio play; if the cached audio file is incomplete, the target audio with lower tone quality is cached and played preferentially.
In another possible embodiment, when the target audio is played according to the buffered audio file, or played according to the local audio file, or played while buffered and the buffering is completed, the pre-buffering step of the next audio may be performed. The embodiment of how to pre-cache may refer to the above embodiment, and this embodiment is not described herein.
