[0034] Figure 1 is a flow chart of an audio processing method provided by an embodiment of the present disclosure. The embodiment of the present disclosure is applicable to situations where continuous singing is performed in a singing application and the audio generated by the singing is merged. The method can be executed by an audio processing device, which can be implemented in the form of software and / or hardware and is generally integrated on any electronic device with network communication function, which can be a mobile terminal, PC or server, etc.

[0035] As shown in FIG1 , the audio processing method according to an embodiment of the present disclosure may include the following steps:

[0036] S110: Determine multiple target audio segments.

[0037] S120. Determine target audio attribute information of each target audio segment. The target audio attribute information is used to mark available audio segments in the target audio segment. The available audio segments meet the following conditions: there is no overlap between the reference audio segment and the available audio segment. The reference audio segment is collected after the target audio segment, and both the reference audio segment and the target audio segment are audio segments formed by using the same preset audio file as the singing material.

[0038] Referring to FIG2 , schematic interface diagrams of the “song middle page”, “singing recording page” and “preview page” involved in the singing application are provided in sequence. In the “singing recording page” shown in FIG2 , the singing subject can use the audio clips selected from the same preset audio file provided in the singing application at different acquisition times as singing materials to repeatedly practice singing. The audio clips selected from the preset audio file at each acquisition time may be the same, partially the same, or different. A plurality of target audio clips are obtained by singing with the selected audio clips as singing materials at different acquisition times and collecting the audio clips formed by the singing. Moreover, the audio clips selected from the preset audio file at each acquisition time may overlap, so there will be overlapping parts between the newly formed audio clips when singing according to the selected audio clips as singing materials, that is, there may be many audio clips with overlapping intervals between the target audio clips, resulting in unclear audio after the audio is merged.

[0039] When using a singing application to sing, for the audio clips formed when singing the same audio clip selected from a preset audio file at different collection times, only if the user is not satisfied with the newly formed audio clip of the previous singing, will the user choose to sing again at the next collection time to form a new audio clip until the audio clip formed by repeated singing is satisfactory. It can be seen that the availability of audio clips with a later collection time is stronger than that of audio clips with an earlier collection time. Then the audio clips formed when singing the same audio clip will usually be dominated by audio clips with a later collection time. At the same time, there are some audio clips in the audio clip with an earlier collection time that are not reflected in the audio clips after the collection time. Therefore, the audio clips with an earlier collection time cannot be directly eliminated, but they must be selectively eliminated and retained.

[0040] To this end, for each target audio segment, it can be determined whether there is a series of audio segments whose collection time is later than that of the target audio segment among the multiple target audio segments. If so, the series of audio segments whose collection time is later than that of the target segment among the multiple target audio segments is selected as the reference audio segment corresponding to the target audio segment. If not, it is determined that there is no corresponding reference audio segment for the target audio segment. In some embodiments, the reference audio segment corresponding to the target audio segment is an audio segment formed by singing an audio segment selected from the same preset audio file, whose collection time is later than that of the target audio segment, so that the reference audio segment whose collection time is later than that of the target audio segment can be used to correct and eliminate overlapping audio segments in the target audio segment that do not meet the requirements.

[0041] Referring to Figure 3a, the newly generated audio clips, which are selected from the same preset audio file at different capture times and used as singing materials, are sequentially referred to as the audio clip of capture 1, the audio clip of capture 2, and the audio clip of capture 3. These are denoted as the multiple target audio clips to be merged. Furthermore, for each of the multiple target audio clips, a reference audio clip can be selected from audio clips that were captured later than the target audio clip.

[0042] The audio segments of Collection 1, Collection 2, and Collection 3 shown in Figure 3a can all be used as target audio segments in sequence. When the target audio segment is the audio segment of Collection 1, the reference audio segments corresponding to the audio segment of Collection 1 are, in sequence, the audio segments of Collection 2 and Collection 3. As can be seen from Figure 3a, there are some overlapping audio segments between the audio segments of Collection 2 and Collection 1. Since the audio segment of Collection 2 was collected later than the audio segment of Collection 1, the audio segment of Collection 1, which is used as the target audio segment, needs to be discarded when the audio segment is subsequently merged.

[0043] Referring to Figure 3a, similarly, the audio segments of Collection 3 partially overlap with those of Collection 1. Since the audio segments of Collection 3 were collected later than those of Collection 1, the overlapping segments of Collection 1, as the target audio segments, also need to be discarded during the subsequent merging process. Referring to Figure 3b, when the audio segments of Collection 1 are used as the target audio segments, the overlapping segments of Collection 1, Collection 2, and Collection 3 are discarded, and the audio segments of Collection 1 are split into two usable audio segments corresponding to Collection 1.

[0044] To this end, when a reference audio segment corresponding to a target audio segment is obtained, based on the overlap between the target audio segment and the corresponding reference audio segment, the portion of the target audio segment that does not overlap with the reference audio segment can be identified as an available audio segment, and the positions of the available audio segments in the target audio segment can be marked. Furthermore, when a reference audio segment corresponding to the target audio segment is not obtained, the entire target audio segment can be directly identified as an available audio segment, and the positions of the available audio segments in the target audio segment can be marked. By marking the positions of the available audio segments in the target audio segment, it is possible to retain the available audio segments when merging multiple target audio segments.

[0045] S130: Process multiple target audio segments based on the target audio attribute information of each target audio segment.

[0046] For each of the multiple target audio segments, the target audio attribute information can be used to mark the available audio segments in each target audio segment that do not overlap with the reference audio segment corresponding to the target audio segment, and the marked target audio segments can be saved independently. This allows the user to directly use the available audio segments in the target audio segments for audio merging when subsequently selecting to merge the target audio segments, eliminating duplicate audio segments in the merged audio and resolving the issue of audio recording not being able to be performed smoothly and with overlapping recorded audio in singing applications.

[0047] Optionally, available audio segments that do not overlap with reference audio segments corresponding to the target audio segment are selected from each target audio segment, and then the selected available audio segments are decoded and then merged to obtain a merged audio file.

[0048] As an optional but non-limiting implementation, processing multiple target audio segments based on target audio attribute information of each target audio segment may include the following steps A1-A2:

[0049] Step A1: For each target audio segment, based on the target audio attribute information of the target audio segment, crop an available audio segment from the target audio segment and determine the audio starting point corresponding to the available audio segment. The available audio segment is an audio segment selected from the target audio segment that can be used for audio merging. The audio starting point indicated by the target audio attribute information is based on the audio progress time of the available audio segment in the preset audio file.

[0050] Step A2: merging the available audio segments cut from the target audio segments in accordance with the order of the audio starting points corresponding to the available audio segments.

[0051] The target audio attribute information indicates the audio starting point of the available audio segment in the target audio segment that can be used for audio merging. The audio starting point indicated by the target audio attribute information can refer to the starting point of the available audio segment mapped to the audio progress time corresponding to the preset audio file. After the available audio segments that need to be merged are cut out from each target audio segment, the selected available audio segments can be decoded, and the corresponding decoded available audio segments can be spliced ​​together in the time sequence of the audio starting points corresponding to each available audio segment to obtain a merged audio file. Among them, the AVComposition library or a third-party audio cutting library can be used to implement the cutting of available audio segments from the target audio segment.

[0052] The solution of the embodiment of the present disclosure is to obtain multiple target audio segments by selecting audio segments from a preset audio file in a singing application as singing materials and then continuing the next singing without waiting for audio processing after one singing is completed. In this way, it is possible to perform smooth singing in the singing application without waiting for the audio processing to be completed before continuing the singing, which can reduce the jamming in the singing application to a certain extent. At the same time, after obtaining multiple target audio segments, the reference audio segment corresponding to each target audio segment can be determined. By comparing the target audio segment with the reference audio segment, the target audio attribute information for marking the available audio segments in the target audio segment that do not overlap with the reference audio segment can be determined, and then the target audio segments that are uniformly marked can be merged without overlapping audio according to the target audio attribute information of each target audio segment. Since no audio merging operation is performed when the target audio segments are uniformly obtained, the overlapping parts in the audio segments do not need to be processed, which can save some computing performance consumption.

[0053] Figure 4 is a flow chart of another audio processing method provided in an embodiment of the present disclosure. The technical solution of this embodiment further optimizes the process of determining multiple target audio segments in the aforementioned embodiment on the basis of the aforementioned embodiment. This embodiment can be combined with various optional solutions in one or more of the aforementioned embodiments.

[0054] As shown in FIG4 , the audio processing method according to an embodiment of the present disclosure may include the following steps:

[0055] S410: Determine a plurality of candidate audio segments, where the plurality of candidate audio segments are newly formed audio segments based on audio segments selected from the same preset audio file at different acquisition times as singing materials.

[0056] Optionally, when the audio segments selected from the same preset audio file at different acquisition times are identical or partially identical, and the audio segments selected from the same preset audio file at different acquisition times are identical or partially identical, the multiple candidate audio segments are at least partially identical. The multiple candidate audio segments are audio segments formed by pronouncing the audio segments selected from the same preset audio file at different acquisition times as singing materials.

[0057] Referring to Figures 3a and 3b, when practicing singing in a singing application, the reason why multiple target audio clips are collected and overlapped is that, on the one hand, the selected audio clips will be practiced repeatedly and audio will be collected as singing materials. For example, if the audio clip does not meet the singing requirements and needs to be practiced repeatedly and recorded, the audio clips selected from the same preset audio file at different collection times are the same. On the other hand, it is because the audio formed by the singing needs to be shortened and spliced ​​together. If the front and back audio clips of the singing cannot be connected, then even if they are spliced ​​into one audio file, the audio will be incomplete in the middle. In order to continue the audio clip obtained from the previous singing, the singing practice will be repeated on the end of the audio clip of the previous singing. The audio clips corresponding to the two collection moments are partially the same. At this time, the audio clips selected from the same preset audio file at different collection times are partially the same.

[0058] As an optional but non-limiting implementation, determining multiple candidate audio segments may include the following steps B1-B2:

[0059] Step B1, in response to the audio collection operation, collect the audio segment formed based on the preset singing material to obtain a candidate audio segment and mark the corresponding collection time, wherein the preset singing material is the singing material corresponding to the audio segment selected from the preset audio file.

[0060] Referring to Figure 2, in the singing application, the singing recording page starts the audio collection operation when the singing recording control in the singing recording page is triggered and clicked. At this time, the singing can be performed according to the audio clip provided in the preset audio file as the singing material, and the audio clip formed by the singing can be collected in real time through the audio collector. The audio collection operation ends when the singing recording control is triggered and clicked again. The audio clip collected between the start of the audio collection operation and the pause of the audio collection operation is the audio clip selected from the preset audio file as the candidate audio clip newly formed as the singing material. At the same time, the collection time of the candidate audio clip is marked, which can also be understood as the singing recording time of the candidate audio clip. In some embodiments, the audio collector can be implemented using the AudioUnit library or a third-party audio collection library.

[0061] When practicing singing in a singing application, there may be situations where the same selected audio clip does not meet the singing requirements and needs to be repeatedly practiced and recorded, or the end of the audio clip of the previous singing needs to be repeated for singing practice in order to continue the previous singing. For this reason, in response to another audio collection operation, the audio clip selected from the preset audio file is collected as the audio clip formed by the singing material to obtain the next candidate audio clip and mark the corresponding collection time. That is to say, after completing the collection of a candidate audio clip for singing, the next singing can be continued. It is also necessary to collect the audio clip formed by singing from the start of the audio collection operation to the end of the audio collection operation, obtain another candidate audio clip and mark the collection time corresponding to the candidate audio clip. When the audio clips selected from the same preset audio file at different collection times are the same or partially the same, then the obtained candidate audio clips are at least partially overlapped.

[0062] Step B2: Determine the candidate audio segments corresponding to the multiple audio collection operations as multiple candidate audio segments, and the preset audio file used in the multiple audio collection operations is the same audio file.

[0063] Merging and removing overlapping audio segments is only necessary when the audio segments selected as singing materials at different acquisition times originate from the same preset audio file. If they do not originate from the same audio file, merging and removing overlapping audio segments is not necessary.

[0064] S420: Determine multiple target audio segments from multiple candidate audio segments.

[0065] The reference audio segment is collected later than the target audio segment, and the target audio segment and the reference audio segment are newly generated audio segments based on audio segments selected from the same preset audio file as the performance material. The reference audio segment is collected after the target audio segment and is generated from the same preset audio file as the target audio segment.

[0066] Optionally, all of the candidate audio segments may be used as the target audio segments, with each candidate audio segment serving as a target audio segment. Alternatively, some of the candidate audio segments may be selected from the candidate audio segments as the target audio segments, with each selected candidate audio segment serving as a target audio segment.

[0067] As an optional but non-limiting implementation, determining multiple target audio segments from multiple candidate audio segments may include the following steps:

[0068] Step C1: Sort the candidate audio segments included in the multiple candidate audio segments according to the chronological order of their collection time, and determine the candidate audio segments selected in sequence as the multiple target audio segments according to the sorting results of the candidate audio segments, until all the candidate audio segments in the multiple candidate audio segments are traversed or a candidate audio segment is selected.

[0069] S430. Determine target audio attribute information of each target audio segment. The target audio attribute information is used to mark available audio segments in the target audio segment. The available audio segments meet the following conditions: there is no reference audio segment overlapping with the available audio segment, the reference audio segment is collected after the target audio segment, and both the reference audio segment and the target audio segment are audio segments formed by using the same preset audio file as the singing material.

[0070] S440: Process the multiple target audio segments based on the target audio attribute information of each target audio segment.

[0071] The solution of the disclosed embodiment selects an audio clip from a preset audio file in a singing application as singing material. After a performance is completed, the selected audio clip is directly used as singing material without waiting for audio processing. The singing material is then used to continue the next performance to form an audio clip. After multiple performances are performed by selecting singing material, multiple target audio clips are sequentially obtained. This allows for smooth singing in the singing application without waiting for audio processing to complete before continuing. This can reduce lag in the singing application to a certain extent. At the same time, after obtaining multiple target audio clips, it can be determined whether each target audio clip has a corresponding reference audio clip. If a reference audio clip exists, the target audio clip can be compared with the reference audio clip to determine the target audio attribute information used to mark the available audio clips in the target audio clip that do not overlap with the reference audio clip. Then, according to the target audio attribute information of each target audio clip, the marked target audio clips can be merged to achieve non-overlapping audio. Since no audio merging operation is performed when the target audio clips are uniformly obtained, the overlapping portions of the audio clips do not need to be processed, which saves some computing power. Figure 5 is a flow chart of another audio processing method provided by an embodiment of the present disclosure. The technical solution of this embodiment further optimizes the process of determining the target audio attribute information of each target audio segment in the aforementioned embodiment on the basis of the aforementioned embodiment. This embodiment can be combined with various optional solutions in one or more of the aforementioned embodiments.

[0072] As shown in FIG5 , the audio processing method according to the embodiment of the present disclosure may include the following steps:

[0073] S510: Determine multiple target audio segments.

[0074] S520. Determine first audio attribute information of the target audio segment, where the first audio attribute information is used to indicate the audio starting point and audio duration of the target audio segment. The audio starting point indicated by the first audio attribute information is based on the audio progress time representation of the target audio segment in a preset audio file.

[0075] The first audio attribute information indicates the audio starting point and audio duration of the target audio segment. The audio starting point indicated by the first audio attribute information may refer to the starting point of the target audio segment mapped to the audio progress time corresponding to the preset audio file.

[0076] S530: Determine a reference audio segment corresponding to the target audio segment, and determine second audio attribute information of the reference audio segment. The second audio attribute information is used to indicate an audio start point and audio duration of the reference audio segment. The audio start point indicated by the second audio attribute information is based on an audio progress time representation of the reference audio segment in a preset audio file. The second audio attribute information indicates the audio start point and audio duration of the reference audio segment. The audio start point indicated by the second audio attribute information may refer to the audio progress time corresponding to the mapping of the starting point of the reference audio segment to the preset audio file.

[0077] S540. Determine the target audio attribute information of the target audio segment based on the first audio attribute information and the second audio attribute information. The target audio attribute information is used to indicate whether there is an available audio segment and the audio starting point and audio duration of at least one available audio segment. The available audio segment is an audio segment selected from the target audio segment and can be used for audio merging.

[0078] In some embodiments, the target audio attribute information is used to mark the available audio segments in the target audio segment, and the available audio segments meet the following conditions: there is no reference audio segment overlapping with the available audio segment, the reference audio segment is collected after the target audio segment, and both the reference audio segment and the target audio segment are audio segments formed by using the same preset audio file as the singing material.

[0079] Optionally, the target audio attribute information is used to mark available audio segments in the target audio segment that do not overlap with the reference audio segment when the reference audio segment exists, and all target audio segments when the reference audio segment does not exist, as available audio segments.

[0080] The target audio attribute information may indicate whether an available audio segment exists in the target audio segment and, if an available audio segment exists in the target hidden segment, the audio start point of the available audio segment that can be used for audio merging. The audio start point indicated by the target audio attribute information may be the start point of the available audio segment mapped to the audio progress time corresponding to the preset audio file.

[0081] As an optional but non-limiting implementation, determining the reference audio segment corresponding to the target audio segment includes the following steps C1-C2:

[0082] Step C1: sort the target audio segments in the plurality of target audio segments according to the chronological order of their corresponding acquisition times.

[0083] Step C2: For each target audio segment, determine the target audio segment that is sorted after the target audio segment as the reference audio segment corresponding to the target audio segment.

[0084] As an optional but non-limiting implementation, determining the target audio attribute information of the target audio segment based on the first audio attribute information and the second audio attribute information may include the following steps D1-D2:

[0085] Step D1: If it is determined based on the first audio attribute information and the second audio attribute information that the audio start point of the target audio segment is smaller than the audio start point of the reference audio segment and there are overlapping audio segments, then the audio start point indicated by the first audio attribute information is determined as the audio start point of the available audio segment indicated by the target audio attribute information.

[0086] Step D2: Determine the subtraction value between the audio starting point indicated by the second audio attribute information and the audio starting point indicated by the first audio attribute information as the audio duration of the available audio segment indicated by the target audio attribute information.

[0087] In a singing application, an embodiment of the present disclosure selects an audio clip from a preset audio file as singing material for a performance. After a performance is completed, the selected audio clip is directly used as singing material, without waiting for audio processing. The selected audio clip is then used to continue the next performance, forming an audio clip. By selecting singing material multiple times and performing the performance, multiple target audio clips are sequentially obtained. This allows for smooth singing in the singing application without having to wait for audio processing to complete before continuing. This can reduce lag in the singing application to a certain extent. Furthermore, after obtaining multiple target audio clips, it is possible to determine whether each target audio clip has a corresponding reference audio clip. If a reference audio clip exists, the target audio clip can be compared with the reference audio clip to determine target audio attribute information for marking available audio clips within the target audio clip that do not overlap with the reference audio clip. The marked target audio clips can then be merged according to their target audio attribute information to achieve non-overlapping audio. Since no audio merging operation is performed when the target audio clips are uniformly obtained, the overlapping portions of the audio clips do not need to be processed, saving some computing power.

[0088] Referring to the first one from the left in Figure 6, taking the audio segment of Collection 1 as the target audio segment and the audio segment of Collection 2 as the reference audio segment as an example, the audio starting point indicated by the first audio attribute information of the target audio segment is smaller than the audio starting point indicated by the second audio attribute information of the reference audio segment, and the sum of the audio starting point indicated by the first audio attribute information and the audio duration is greater than the audio starting point indicated by the second audio attribute information of the reference audio segment. From this, it can be seen that there is an overlapping audio segment between the right part of the audio segment of Collection 1 and the left part of the audio segment of Collection 2, and the right part of the audio segment of Collection 1 can be right-segmented. At this time, the audio starting point indicated by the first audio attribute information can be directly determined as the audio starting point of the available audio segment, and the subtraction value between the audio starting point indicated by the second audio attribute information and the audio starting point indicated by the first audio attribute information can be determined as the audio duration of the available audio segment.

[0089] As another optional but non-limiting implementation, determining the target audio attribute information of the target audio segment based on the first audio attribute information and the second audio attribute information may include the following steps E1-E3:

[0090] Step E1: If it is determined based on the first audio attribute information and the second audio attribute information that the audio starting point of the target audio segment is greater than the audio starting point of the reference audio segment and there are overlapping audio segments, then the sum of the audio starting point indicated by the second audio attribute information and the audio duration indicated by the second audio attribute information is determined as the audio starting point of the available audio segment indicated by the target audio attribute information.

[0091] Step E2: Determine the duration of the overlapping audio segments by subtracting the audio starting point indicated by the target audio attribute information from the audio starting point indicated by the first audio attribute information.

[0092] Step E3: Determine the audio duration of the available audio segment indicated by the target audio attribute information as the subtraction value between the audio duration indicated by the first audio attribute information and the duration of the overlapping audio segment.

[0093] Referring to the second one from the left in Figure 6, taking the audio segment of Collection 1 as the target audio segment and the audio segment of Collection 2 as the reference audio segment as an example, the audio starting point indicated by the first audio attribute information of the target audio segment is greater than the audio starting point indicated by the second audio attribute information of the reference audio segment, and the sum of the audio starting point indicated by the second audio attribute information and the audio duration is greater than the audio starting point indicated by the first audio attribute information of the target audio segment. From this, it can be seen that there are overlapping audio segments between the audio segment of Collection 1 and the audio segment of Collection 2, specifically, the left part of the audio segment of Collection 1 overlaps with the right part of the audio segment of Collection 2. The left part of the audio segment of Collection 1 can be split on the left. At this time, the subtraction value between the audio starting point indicated by the target audio attribute information and the audio starting point indicated by the first audio attribute information can be determined as the overlapping audio segment duration of the right part of the audio segment of Collection 1 and the left part of the audio segment of Collection 2. Then, the subtraction value of the audio duration indicated by the first audio attribute information and the duration of the overlapping audio segment is determined as the audio duration of the available audio segment, and the addition value of the audio starting point indicated by the second audio attribute information and the audio duration indicated by the second audio attribute information is determined as the audio starting point of the available audio segment.

[0094] As another optional but non-limiting implementation, determining the target audio attribute information of the target audio segment based on the first audio attribute information and the second audio attribute information may include the following steps F1-F5:

[0095] Step F1. If the audio starting point of the target audio segment is determined to be smaller than the audio starting point of the reference audio segment based on the first audio attribute information and the second audio attribute information, and the sum of the audio starting point and the audio duration of the target audio segment is greater than the sum of the audio starting point and the audio duration of the reference audio segment, then the audio starting point indicated by the first audio attribute information is determined to be the audio starting point of the first available audio segment indicated by the target audio attribute information.

[0096] Step F2: Determine the subtraction value between the audio starting point indicated by the second audio attribute information and the audio starting point indicated by the first audio attribute information as the audio duration of the first available audio segment indicated by the target audio attribute information.

[0097] Step F3: Determine the sum of the audio start point indicated by the second audio attribute information and the audio duration indicated by the second audio attribute information as the audio start point of the second available audio segment indicated by the target audio attribute information.

[0098] Step F4: Determine the duration of the overlapping audio segments by subtracting the audio starting point indicated by the target audio attribute information from the audio starting point indicated by the first audio attribute information.

[0099] Step F5: Determine the subtraction value between the audio duration indicated by the first audio attribute information and the duration of the overlapping audio segment as the audio duration of the second available audio segment indicated by the target audio attribute information.

[0100] In some embodiments, the first available audio segment and the second available audio segment are two audio segments selected from the target audio segment and capable of being used for audio merging.

[0101] Referring to the third audio segment from the left in Figure 6 , taking the audio segment from Collection 1 as the target audio segment and the audio segment from Collection 2 as the reference audio segment, the overlapping audio segment of the audio segments from Collection 1 and Collection 2 is located in the middle of the audio segment from Collection 1. In this case, the right-side segmentation of steps D1-D2 and the left-side segmentation of steps E1-E3 can be combined to implement the process from steps F1-F5. This process sequentially segments the left and right sides of the audio segment from Collection 1 into a first usable audio segment and a second usable audio segment. The first and second usable audio segments are then selected from the target audio segment and used for audio merging.

[0102] As an optional but non-limiting implementation, determining the target audio attribute information of the target audio segment based on the first audio attribute information and the second audio attribute information may include the following steps:

[0103] If it is determined based on the first audio attribute information and the second audio attribute information that the audio starting point of the target audio segment is greater than the audio starting point of the reference audio segment, and the sum of the audio starting point and the audio duration of the target audio segment is less than the sum of the audio starting point and the audio duration of the reference audio segment, then the target audio attribute information of the target audio segment is determined to be that there is no available audio segment in the target audio segment.

[0104] As shown in Figure 6, the fourth audio clip from the left is the target audio clip, and the audio clip from Collection 2 is the reference audio clip. If the audio clip from Collection 1 is completely overwritten by the audio clip from Collection 2, then all the audio clips from Collection 1 are overlapping audio clips. In this case, the audio clip from Collection 1 can be deleted and overwritten, indicating that there are no usable audio clips in the target audio clip.

[0105] S550: Process multiple target audio segments based on the target audio attribute information of each target audio segment.

[0106] The solution of the embodiment of the present disclosure is to obtain multiple target audio segments by selecting audio segments from a preset audio file in a singing application as singing materials and then continuing the next singing without waiting for audio processing after one singing is completed. In this way, it is possible to perform smooth singing in the singing application without waiting for the audio processing to be completed before continuing the singing, which can reduce the jamming in the singing application to a certain extent. At the same time, after obtaining multiple target audio segments, the reference audio segment corresponding to each target audio segment can be determined. By comparing the target audio segment with the reference audio segment, the target audio attribute information for marking the available audio segments in the target audio segment that do not overlap with the reference audio segment can be determined, and then the target audio segments that are uniformly marked can be merged without overlapping audio according to the target audio attribute information of each target audio segment. Since no audio merging operation is performed when the target audio segments are uniformly obtained, the overlapping parts in the audio segments do not need to be processed, which can save some computing performance consumption.
