Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In some prior art, when a plurality of audio files are input and need to be output, if the sampling rates of the plurality of audio files are different, the sampling rates of the plurality of audio files need to be adjusted to be consistent through sound mixing processing, resampling and the like, so that the sound quality is reduced.
In order to solve the above problems, the present disclosure provides an audio playing method 10, which avoids the sound quality degradation caused by audio mixing, and the method can be used in various terminal devices, such as mobile phones, tablet computers, and the like, referring to fig. 1, the audio playing method 10 includes steps S11-S16, which are described in detail below:
in step S11, a play start instruction for the first audio is received.
The mobile terminal may obtain a system play instruction in some states, or may play a first audio based on a current application program of a user or a play instruction input by the user, where the first audio may be a system prompt tone, an audio in the application program, or other audio to be played according to the instruction.
Step S12, in response to the play start instruction, determines whether N second audios are currently being played, where N is a positive integer greater than or equal to 1.
After receiving an instruction of playing the first audio, judging whether other audio which is being played exists or not, and if the other audio is not played at present, directly playing the first audio. If there is an audio being played, step S13 and step S16 of the embodiment of the present disclosure need to be executed to ensure the sound effect quality of the simultaneous playing of multiple audios.
The plurality of second audios can be a plurality of different audios, and the sampling frequencies of the plurality of second audios can be the same or different; the first audio, and the second audio, may be audio having different sampling rates, in some embodiments the sampling rate of the first audio is different than the sampling rate of at least one of the N second audios due to different audio sources. Through the mode of the embodiment of the disclosure, the audio frequencies with different sampling rates are played simultaneously, the playing quality can be ensured, and the sound effect loss caused by resampling is avoided.
In step S13, under the condition that N second audios are currently being played, the total number of the currently to-be-played audios is updated to N +1, where the currently to-be-played audio includes the first audio and the N second audios.
When the second audio which is being played exists, the total number of the current audio to be played is updated, so that the playing switching time length can be determined and the alternate playing can be carried out based on the updated total number in the following process.
In step S14, the play switching time length is determined.
The user can determine the playing switching time length according to actual needs or equipment capability. The long switching time of the playing results in that when the playing is performed in turn later, the interval between two times of playing of a single audio is too long, and the interval may be perceived by human ears, so that the switching time is within a certain range to ensure that the human ears cannot recognize. A shorter switching time period can bring higher sound quality, but also causes a greater operational burden on the device, so that the setting of the switching time period can also be determined according to the device capability.
Step S15, with the play switching duration as a unit, respectively dividing the unplayed part of each audio in the currently to-be-played audio into a plurality of audio segments.
In the embodiment of the present disclosure, since the audio needs to be played in turn, according to the play switching duration, all the unplayed portions of the audio to be played are divided, that is, each audio is divided into a plurality of audio segments each having a time length equal to the play switching duration. The division referred to herein is a virtual division, and instead of dividing a complete audio into a plurality of file segments, the audio is divided only temporally on the time line of the audio to form a plurality of time intervals.
And step S16, taking the playing switching duration as a unit, sequentially playing an audio clip of each current audio to be played in turn according to the time line, wherein the time interval between the playing ending time of the previous audio clip and the playing starting time of the next audio clip of each current audio to be played on the time line does not exceed a preset maximum threshold value.
Each audio has a respective time line, after the audio starts to be played, the time line starts to continuously advance, in the advancing process, the played audio is switched, even if one audio is not the currently switched played audio, the time line continuously advances, and when the audio is switched to be played, a corresponding audio clip needs to be played according to a node where the current time line of the audio advances. Meanwhile, in order to ensure the playing quality when each audio is played in turn, it is necessary to ensure that the playing interval of any one audio in two times cannot exceed a predetermined maximum threshold, and when the playing interval of one audio in two times exceeds a certain degree, the audio can be perceived by human ears. Generally, the predetermined maximum threshold may be set to 0.1 second, i.e. the playing end time of an audio segment of any playing audio, and the time between the next time when the audio is played by turns is 0.1 second. In some cases, the predetermined maximum threshold may also be set to a duration less than 0.1 second to ensure playback quality.
Through the embodiment, the audio quality reduction caused by resampling for simultaneously playing a plurality of audios can be avoided, so that the audio playing effect is ensured.
In an embodiment, as shown in fig. 2, step S16 may further include: step S161, determining a playing sequence of the current audio to be played, where the first audio is located at the head of the playing sequence; and step S162, when the playing of the audio clip of any one of the current audio to be played is finished, playing the next audio clip of the audio to be played according to the time line of the next audio to be played based on the playing sequence. In this embodiment, a plurality of audio frequencies to be played currently may be sequenced to form a playing sequence, and the audio frequencies are sequentially played in turn according to the sequence. In addition, in this embodiment, since the first audio is just added, in order to reduce the response time between the receiving of the first audio play start instruction and the actual playing of the first audio, the first audio may be set at the head of the play sequence. And if the second audio which is being played currently exists, determining a playing sequence according to all the audio which is required to be played simultaneously currently. According to the embodiment of the present disclosure, if there are a plurality of second audios that are played simultaneously, and these second audios are played according to the method of the embodiment of the present disclosure, there is a corresponding play sequence, at this time, only the first audio needs to be added to the head position of the existing play sequence, and then, the first audio is played in turn according to the updated play sequence. If there is no audio currently being played, a play sequence may be created according to the first audio, or a play sequence may be created later in the playing process if there is audio to be played simultaneously. For example, two audios are required to be played simultaneously currently, the playback switching time is set to 0.05 second, according to the timeline, an audio segment of 0-0.05 second from the current time start of the first audio a is played first, the audio segment is switched to the second audio B, the audio segment of 0.05 second after 0.05 second has been shifted on the playback timeline, and the audio segment of 0.1-0.15 second relative to the time start on the playback timeline of the first audio a is switched back again, so that the two audios are played alternately.
Since the time for starting playing of each audio is not necessarily the same, when playing in turns, playing in turns can be performed based on the transition of the respective timeline. Taking the two audios as an example, the audio a starts to be played for 1 second, at this time, the audio B needs to be played based on the instruction, the playing switching time length is determined to be 0.05 second, after the sequence of the two audios is determined, the audio a starts to be played in turn, and the audio clip of the audio B is played in 0-0.05 second of the time line of the audio B; then switching is carried out, the audio A is played, and at the moment, based on the time line of the audio A, the audio segment of 1.05-1.1 seconds on the time line is played; then switching is carried out, and audio clips of 0.15-0.2 seconds on the audio B time line are played, and the like.
According to the embodiment of the disclosure, the plurality of audios can be audio files with different sampling rates, and the method of the embodiment can output the plurality of audios in high quality, so that the tone quality reduction caused by sound mixing is avoided.
In an embodiment, the audio playing method 10 may further include: responding to a playing ending instruction of any one of the N +1 current audio to be played, updating the current audio to be played and updating the total number of the current audio to be played to be N; re-determining the play switching duration; and re-determining the playing sequence of the audio to be played currently. In this embodiment, the total number of the currently-played audio may be updated based on a user instruction, or an end instruction issued when the audio playing is finished, or the like. And simultaneously, the playing time length and the playing sequence are also determined again. After the playing time length is determined again, the audio to be played currently can be divided again. Since the original playing sequence has an audio technology, the playing sequence needs to be updated again, and the audio that is finished playing is removed from the original playing sequence, so as to avoid that the audio that is finished playing interferes the process when the audio is played in turn, and the audio that is not finished playing can be played in turn smoothly. In this embodiment, the durations of the multiple audios may be different, and the playing start times may also be different, and in the process of playing in turns, if one or more of the audios finishes playing, the audio is not played again, and the rest audios continue to be played in turns. If only one audio is left, only the audio needs to be played until all the audio is played.
In one embodiment, step S14 may include: and determining the playing switching time length according to the total number N +1 of the current audio to be played and a preset maximum threshold value, wherein the value N obtained by subtracting 1 from the total number N +1 of the current audio to be played is multiplied by the playing switching time length and is equal to the preset maximum threshold value. In this embodiment, the mode of determining the playing switching duration is mainly determined according to the predetermined maximum threshold and the total number of the currently to-be-played audio, and as mentioned above, it needs to be ensured that an interval between two times of playing audio segments of an audio in the process of sequentially playing the audio in turn cannot exceed the predetermined maximum threshold, and the interval is the duration of playing other N audio to be played in turn, therefore, according to this relationship, a quotient obtained by dividing the predetermined maximum threshold by N (the total number of the currently to-be-played audio is N +1) is used as the playing switching duration, so that the playing effect is ensured, and the power consumption of the device operation is also maximally reduced.
In another embodiment, step S14 may include: determining the play switching time length comprises the following steps: judging whether the total number N +1 of the current audio to be played is greater than a number threshold value; if the total number N +1 of the current audio to be played is less than or equal to the number threshold, determining the playing switching time length based on a first preset time length; if the total number N +1 of the current audio to be played is greater than the number threshold, determining the playing switching time length according to the total number N +1 of the current audio to be played and a preset maximum threshold, wherein the value N obtained by subtracting 1 from the total number N +1 of the current audio to be played is multiplied by the playing switching time length and is equal to the preset maximum threshold. In this embodiment, a suitable first preset duration may be preset and used as the play switching duration to ensure the effect of alternate playing. Meanwhile, if too many audios need to be played simultaneously, the first preset time length is adopted, which may cause that the interval between two playing of the same audio is too long and is longer than the preset maximum threshold value in the process of sequentially playing the same audio in turn. Therefore, a quantity threshold value can be determined according to the mode of dividing the preset maximum threshold value by the first preset time length and the like, and when the total number of the current audio to be played does not exceed the quantity threshold value, the first preset time length is directly adopted as the playing switching time length, so that the method is simple and efficient; when the total number of the current audio to be played exceeds the number threshold, the play switching duration may be determined in the manner of the foregoing embodiment, so as to ensure the play quality.
In an embodiment, step S14 may further include: the playing switching time length is longer than a second preset time length. If the audio segment into which an audio is divided is segmented, i.e. the playback switching time is too short, the playback quality is also affected. Therefore, a second preset time length which is less than the first preset time length is set, and when the playing switching time length is determined, the playing switching time length is ensured to be greater than the second preset time length, so that the playing quality is ensured. If the playing switching time length determined based on the total number of the current audio to be played cannot meet the requirement of being longer than the second preset time length, the playing can be paused or prompt information can be sent out to inform the user.
Fig. 3 illustrates a time diagram of playing multiple audios by turns according to the audio playing method 10 of the present disclosure, as shown in fig. 3, including four audio files: audio a, audio B, audio C and audio D, the audio duration being 0.25 second, 0.15 second, 0.25 second and 0.4 second, respectively. In practice, the audio duration is typically long, and this example is only for the purpose of showing the features of the embodiments of the present disclosure, and therefore is illustrated by way of example of a short duration. In this example, the audio a starts playing first, only one audio a exists at this time, no rotation is needed, when playing reaches 0.1 second, based on the instruction, the audio B, the audio C, and the audio D need to be played simultaneously, the play switching time length is determined to be 0.025 second, according to the method of the embodiment of the present disclosure, each audio is divided into audio segments with a time length of 0.025 second, and then the audio segments are played in turn based on the respective timeline and the play switching time length, in this example, the determined sequence of the playing sequence is the audio a, the audio B, the audio C, and the audio D, after being switched to the audio B to play for 0.025 second, the audio C is switched, and so on. When the time line of the audio A reaches 0.25 second, the audio A and the audio B are played completely, at this time, the audio A and the audio B are removed from the playing sequence, the total updating amount is 2, the updating switching time length is 0.05 second, the updated playing sequence is audio C and audio D, and alternate playing is continued on the basis. When the time line of the audio C reaches 0.25 second, the audio C finishes playing, and then the audio D is continuously played until the audio D finishes playing due to the existence of only the audio D.
