[0046] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0047] It should be noted that, if there is no conflict, the various features in the embodiments of the present invention can be combined with each other, all within the scope of protection of the present invention. In addition, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in a different order from the module division in the device or the flow chart. Furthermore, the words "first", "second", "third", etc. used in the present invention do not limit the data and execution order, but only distinguish the same items or similar items with basically the same functions and effects.

[0048] The embodiment of the present invention provides a method for playing an audio file. Figure 1 , the audio file playing method comprises the following steps:

[0049] S11: When playing an audio source file in a VBR format, convert the audio source file into a target audio file in a CBR format, where the target audio file includes multiple frames of CBR audio data of equal length.

[0050] In this step, the VBR format audio source file uses a dynamic bit rate compression file, and the audio source file includes multiple frames of VBR audio data. The size of each frame of VBR audio data can be the same or different. The CBR format target audio file uses a fixed bit rate compression file, and the size of each frame of CBR audio data in the target audio file is the same. For example, the audio source file includes multiple frames of VBR audio data, and the multiple frames of VBR audio data are {v1, v2, v3, ..., v i ,...v n},v iis the i-th frame of VBR audio data. When the present embodiment detects the playback operation of the audio source file, the audio source file is decoded according to the CBR protocol to obtain a target audio file, which includes multiple frames of CBR audio data, and the multiple frames of CBR audio data are {c1, c2, c3, ..., c j ,...c n}, c j is the j-th frame of CBR audio data.

[0051] S12: In response to the jump play operation, target CBR audio data is determined in the multiple frames of CBR audio data, where the target CBR audio data is CBR audio data corresponding to the jump position of the jump play operation.

[0052] In this step, the jump play operation is an operation of jumping to play the audio source file, wherein the jump play operation includes a fast forward operation, a fast rewind operation or a drag operation, wherein the fast forward operation can be an N-fold fast forward operation, and the fast rewind operation can be an N-fold fast rewind operation, wherein N is a positive number greater than the natural number 1. The drag operation is an operation of dragging the play point on the preset play time bar, for example, dragging the play point to the 50th minute. The jump position is the position of the play point after the jump play operation, for example, if the play point at the 30th minute is dragged to the 50th minute, the play point at the 50th minute is the jump position.

[0053] For example, before the jump play operation is input, the play point is at the 30th minute, and the VBR audio data of the audio source file at the 30th minute is the i+1th frame VBR audio data. After the jump play operation is input, the play point is at the 50th minute, and the VBR audio data of the audio source file at the 50th minute is the i+8th frame VBR audio data, but the CBR audio data of the target audio file at the 50th minute is the j+12th frame CBR audio data, so the j+12th frame CBR audio data is the target CBR audio data.

[0054] S13: Play the target audio file using the target CBR audio data as the starting playback data.

[0055] In this step, for example, this embodiment uses the j+12th frame of CBR audio data as the starting playback data, and starts to play the j+12th frame of CBR audio data, the j+13th frame of CBR audio data, the j+14th frame of CBR audio data, etc. in sequence. Since the CBR format file uses a fixed bit rate compression file, the size of each frame of data is the same. When a jump broadcast occurs, this embodiment quickly locates the target CBR audio data through a linear relationship, and there is no need to open up a large RAM memory to store the location information of each frame of data in the CBR format file, thereby avoiding the waste of memory resources. In addition, the price of RAM memory is relatively expensive compared to other types of storage media. This embodiment uses less RAM memory and can also achieve audio playback, which is relatively cost-saving.

[0056] In some embodiments, determining target CBR audio data in multiple frames of CBR audio data comprises the following steps:

[0057] S121: Determine the target frame number corresponding to the jump position.

[0058] S122: Selecting CBR audio data with a frame number equal to a target frame number from among multiple frames of CBR audio data as target CBR audio data.

[0059] In S121, the target frame number is the frame number of the target CBR audio data. Determining the target frame number corresponding to the jump position includes: determining the play time of the jump position on the preset play time bar, and calculating the target frame number according to the play time, the preset total number of frames and the preset total time.

[0060] Determining the playback duration of the jump position on the preset playback duration bar includes: determining a playback time point of the jump position on the preset playback duration bar, and using the playback time point as the playback duration.

[0061] Calculating the target frame number based on the playback duration, the preset total number of frames, and the preset total duration includes: dividing the playback duration by the preset total duration to obtain the duration ratio, and multiplying the duration ratio by the preset total number of frames to obtain the target frame number. For example, the preset total number of frames is n, and the preset total duration is t all , the playback time is t cur , the target frame number is c target , this embodiment calculates the target frame number according to the following formula: target =n*t cur / t all .

[0062] In S122, this embodiment uses the CBR audio data with the target frame number as the target CBR audio data among the multiple frames of CBR audio data.

[0063] In some embodiments, when playing an audio source file in VBR format, converting the audio source file into a target audio file in CBR format includes the following steps: when playing an audio source file in VBR format, decoding the audio source file to obtain decoded data, storing the decoded data in a first storage location of a preset memory, converting the decoded data into a target audio file in CBR format according to a CBR compression protocol, and storing the target audio file in a second storage location of the preset memory. The preset memory is a flash memory.

[0064] In some embodiments, before decoding the audio source file, the audio file playing method further comprises the following steps: caching VBR audio data of a preset number of frames according to the VBR format, and when playing the audio source file in the VBR format, playing the VBR audio data in sequence. This embodiment can ensure a quick response to the user's playing operation and normal audio playback by caching the VBR audio data of a preset number of frames.

[0065] In some embodiments, the cache duration corresponding to the preset number of frames is greater than or equal to the transcoding duration, and the transcoding duration is the time consumed for converting the audio source file into a target audio file in CBR format. When the user performs a jump playback operation within the cache duration, this embodiment can quickly switch from the audio source file in VBR format to the target audio file in CBR format for playback, avoiding delays and pauses, which is beneficial to improving the smoothness of audio playback.

[0066] In some embodiments, the audio source file includes multiple frames of VBR audio data, and the audio file playing method further includes the following steps:

[0067] S14: When playing the target audio file, synchronously and sequentially retrieve each frame of VBR audio data in the audio source file.

[0068] S15: Determine the starting VBR audio data, where the starting VBR audio data is the VBR audio data in the audio source file, whose frame number is consistent with the frame number of the audio playback data, and the audio playback data is the CBR audio data currently in the playback state.

[0069] S16: Play the target audio file using the initial VBR audio data as the initial playback data.

[0070] After playing the target CBR audio data, this embodiment switches from the target audio file in CBR format to the audio source file in VBR format. This can not only meet the demand for accurate positioning of the playback point required for the jump playback operation, but also meet the demand for continuing to maintain the original playback sound quality of the audio source file.

[0071] In S14, S15 and S16, as mentioned above, the file format of the audio source file is VBR format, and the audio device traverses the audio source file frame by frame. The specific process is as follows:

[0072] A11: Assign i=0.

[0073] A12: Determine the CBR audio data currently being played, and set the CBR audio data currently being played to be the k-th frame of CBR audio data.

[0074] A12: Determine whether the frame number of the i-th frame VBR audio data is consistent with the frame number of the k-th frame CBR audio data. If not, execute step A13; if consistent, execute step A14.

[0075] A13: Assign i=i+1, and return to step A12.

[0076] A14: Use the i-th frame of VBR audio data as the starting playback data to play the target audio file.

[0077] It should be noted that, in each of the above-mentioned embodiments, there is not necessarily a certain order between the above-mentioned steps. A person skilled in the art can understand, based on the description of the embodiments of the present invention, that in different embodiments, the above-mentioned steps may have different execution orders, that is, they may be executed in parallel, may be executed interchangeably, and so on.
