Description

Technical Field

[0001] This disclosure relates to the field of audio technology, and in particular to an audio processing method, apparatus, and storage medium. Background Technology

[0002] Audio signal processing refers to the offline or real-time processing of audio using various signal processing algorithms to extract key feature information of the audio signal, or to reduce noise and enhance the audio, or to change the basic properties of the audio so that it can reproduce the original audio sound on more performance-limited playback devices.

[0003] In related technologies, to enable audio data to reproduce the original audio's sound quality on more performance-constrained playback devices, the common approach is to acquire the audio stream to be played on the playback device, then perform multi-step algorithmic processing on it, such as equalization adjustment and dynamic control algorithms, before sending the processed audio stream to the hardware output responsible for playback. However, since the sound quality of audio playback varies in different playback scenarios (such as music playback and movie watching), different parameter configurations and different processing sequences of algorithms are used for different scenarios. This leads to other abnormal phenomena such as audio jumps, mute, and popping sounds when switching algorithm sequences.

[0004] Therefore, how to provide a smooth audio experience during algorithm sequence switching is an urgent problem to be solved. Summary of the Invention

[0072] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0073] In related technologies, there are two ways to switch the playback algorithm sequence of audio data:

[0074] The first method involves gradually switching the currently playing audio data, which has been processed by the playback algorithm sequence, to the currently playing audio data that has not been processed by the playback algorithm sequence, and then switching to the audio data to be played, which has been processed by the playback algorithm sequence to be switched.

[0075] like Figure 1 As shown, the switching starting point is the current playback algorithm sequence, where the currently played audio data has been processed by the current playback algorithm sequence (Algorithm A, Algorithm C, Algorithm D). The switching ending point is the playback algorithm sequence to be switched to (Algorithm B, Algorithm C, Algorithm A), where the audio data to be switched to has been processed by the playback algorithm sequence (Algorithm B, Algorithm C, Algorithm A). Within a short time, the audio data currently processed by the playback algorithm sequence is transformed into unprocessed audio data. Then, the unprocessed audio data is processed according to the playback algorithm sequence to be switched to obtain the audio data to be switched.

[0076] However, because there is a difference in loudness between the audio before and after the playback algorithm sequence, a perceptible difference in loudness may occur when switching playback algorithm sequences, such as the volume suddenly decreasing.

[0077] The second method involves directly alternating between the current playback algorithm sequence and the playback algorithm sequence to be switched.

[0078] like Figure 2As shown, the currently playing audio data is processed by the current playback algorithm sequence (Algorithm A, Algorithm C, Algorithm D), while the audio data to be switched is processed by the playback algorithm sequence to be switched (Algorithm B, Algorithm C, Algorithm A). The audio data to be switched is simultaneously fed into both the current playback algorithm sequence and the playback algorithm sequence to be switched for processing, and parameter interpolation is performed between the two processing results to transform it into the playback algorithm sequence to be switched. However, this method requires running two playback algorithm sequences simultaneously, significantly increasing the resource consumption of the terminal's operating system.

[0079] In the two methods above, assume that the delays of algorithm A, algorithm B, algorithm C, and algorithm D are respectively d a d b d c d d The switching process, i.e., the delay for parameter interpolation, is m. Therefore, the total delay time is: m + d a +d b +d c Therefore, the switching process takes a long time.

[0080] In an exemplary embodiment of this disclosure, an audio processing method is provided, applied to a terminal, including electronic devices such as smartphones, tablets, smart TVs, and speakers that require audio data processing before playback. Figure 3 This is a flowchart illustrating an audio processing method according to an exemplary embodiment, such as... Figure 3 As shown, it includes the following steps:

[0081] Step S301: Obtain the first playback algorithm sequence of the currently playing first audio data;

[0082] Step S302: Obtain the second playback algorithm sequence of the second audio data to be switched;

[0083] Step S303: Based on whether the first playback algorithm sequence and the second playback algorithm sequence include the same playback algorithm subsequence, switch the first playback algorithm sequence to the second playback algorithm sequence.

[0084] In the exemplary embodiments of this disclosure, in order to overcome the problems existing in the related art when switching playback algorithm sequences, a method for switching playback algorithm sequences, i.e., an audio processing method, is proposed. A first playback algorithm sequence of the currently playing first audio data and a second playback algorithm sequence of the second audio data to be switched are obtained respectively. Based on whether the first and second playback algorithm sequences include the same playback algorithm sub-sequences, the first playback algorithm sequence is switched to the second playback algorithm sequence. This reduces the system resource consumption during the playback algorithm sequence switching process and shortens the switching time.

[0085] A playback algorithm sequence is a sequence of playback algorithm modules used in the processing of audio data when it is played through the terminal's playback device. The playback algorithm sequence can include an arrangement of multiple playback algorithm modules in processing order. In one example, if the audio data needs to be processed sequentially by algorithm A, algorithm C, and algorithm D before it can be played through the terminal's playback device, then the playback algorithm sequence is: Algorithm A, Algorithm C, Algorithm D, which includes three playback algorithm modules.

[0086] The system acquires the first audio data currently playing on the terminal and the second audio data to be switched to. The first and second audio data are audio data that require processing through different playback algorithm sequences, respectively. The system then determines the first playback algorithm sequence for the first audio data and the second playback algorithm sequence for the second audio data. In one example, if the terminal is currently playing a movie in a video application and needs to switch to a music application to play music, the movie content is the first audio data, and the music content is the second audio data.

[0087] Determine whether the first and second playback algorithm sequences contain the same playback algorithm subsequence. The same playback algorithm subsequence is the set of playback algorithm modules that are identical in both sequences. In one example, the first playback algorithm sequence is (Algorithm A, Algorithm C, Algorithm D), and the second playback algorithm sequence is (Algorithm B, Algorithm C, Algorithm A). Then the same playback algorithm subsequence is (Algorithm A, Algorithm C). By determining whether these subsequences are identical, the resource space for switching playback algorithm sequences can be initialized.

[0088] The first playback algorithm sequence is switched to the second playback algorithm sequence based on whether the first and second playback algorithm sequences contain the same playback algorithm subsequences. For example, the switch is made based on the difference between the first and second playback algorithm sequences and the same playback algorithm subsequences. When switching from the first to the second playback algorithm sequence, each playback algorithm module in the playback algorithm sequence is processed separately.

[0089] In the exemplary embodiments of this disclosure, by obtaining the first playback algorithm sequence of the currently playing first audio data and the second playback algorithm sequence of the second audio data to be switched, and by switching the first playback algorithm sequence to the second playback algorithm sequence based on whether the first playback algorithm sequence and the second playback algorithm sequence include the same playback algorithm sub-sequence, the resource consumption during the playback algorithm sequence switching process can be reduced and the switching time of the playback algorithm sequence can be shortened. At the same time, the problem of uneven loudness of audio data before and after the playback algorithm sequence switching is avoided.

[0090] In one exemplary embodiment, Figure 4 This is a flowchart illustrating step S303 of an example embodiment, showing the method of switching the first playback algorithm sequence to the second playback algorithm sequence based on whether the first playback algorithm sequence and the second playback algorithm sequence include the same playback algorithm sub-sequence. Figure 4 As shown, it includes the following steps:

[0091] Step S401: If the first playback algorithm sequence and the second playback algorithm sequence include the same playback algorithm subsequence;

[0092] Step S402: Determine the first playback algorithm sequence and the first difference playback algorithm sequence of the same playback algorithm subsequence, and process the first difference playback algorithm sequence so that the output audio data of the first difference playback algorithm sequence is changed to be the same as the input audio data of the first difference playback algorithm sequence;

[0093] Step S403: Determine the second playback algorithm sequence and the second difference playback algorithm sequence of the same playback algorithm subsequence, and process the second difference playback algorithm sequence to change the output audio data of the second difference playback algorithm sequence to the first preset output audio data.

[0094] When the first playback algorithm sequence and the second playback algorithm sequence include the same playback algorithm subsequence, the first difference playback algorithm sequence is determined between the first playback algorithm sequence and the same playback algorithm subsequence. In one example, the first playback algorithm sequence is (Algorithm A, Algorithm C, Algorithm D), and the second playback algorithm sequence is (Algorithm B, Algorithm C, Algorithm A), then the same playback algorithm subsequence is (Algorithm A, Algorithm C). When the first playback algorithm sequence (Algorithm A, Algorithm B, Algorithm C) and the same playback algorithm subsequence (Algorithm A, Algorithm C) are present, the first difference playback algorithm sequence is (Algorithm D). Since the first playback algorithm sequence is the current playback algorithm sequence, the playback algorithm modules in the first difference playback algorithm sequence need to be removed from the algorithm processing sequence. The first difference playback algorithm sequence is processed so that the output audio data of the first difference playback algorithm sequence is changed to be the same as the input audio data of the first difference playback algorithm sequence, that is, the processing of the audio data by the first difference playback algorithm sequence does not change the characteristics of the audio data. This operation is called "fade-out operation".

[0095] Determine the second playback algorithm sequence and the second differential playback algorithm sequence of the same playback algorithm subsequence. In one example, the first playback algorithm sequence is (Algorithm A, Algorithm C, Algorithm D), the second playback algorithm sequence is (Algorithm B, Algorithm C, Algorithm A), then the same playback algorithm subsequence is (Algorithm A, Algorithm C). When the second playback algorithm sequence (Algorithm B, Algorithm C, Algorithm A) is the same as the same playback algorithm subsequence (Algorithm A, Algorithm C), then the second differential playback algorithm sequence is (Algorithm B). Since the second playback algorithm sequence is the playback algorithm sequence to be switched, the playback algorithm modules in the second differential playback algorithm sequence need to be added to the algorithm processing sequence. The second differential playback algorithm sequence is processed so that the output audio data of the second differential playback algorithm sequence changes to the first preset output audio data. The first preset output audio data is the switching result required in the playback algorithm sequence to be switched. This operation is called the "fade-in operation".

[0096] It should be noted that the first and second difference algorithm playback sequences in the above examples each include only one playback algorithm module, which does not constitute a limitation of this disclosure. The difference playback algorithm sequence is determined based on the same playback algorithm sequence between the first and second playback algorithm sequences in actual applications.

[0097] When the first playback algorithm sequence and the second playback algorithm sequence include the same playback algorithm subsequence, the "fade-out operation" and "fade-in operation" in steps S402 and S403 are performed independently on the different algorithm playback sequences, that is, the corresponding operations can be performed simultaneously without any restriction on the order of the steps.

[0098] In one example, the first playback algorithm sequence is (Algorithm A, Algorithm C, Algorithm D), and the second playback algorithm sequence is (Algorithm A, Algorithm C, Algorithm B). The delays of Algorithms A, B, C, and D are d, respectively. a d b d c d d The switching process, i.e., the delay for parameter interpolation, is m. Therefore, the total delay is the sum of the maximum delay of all playback algorithm modules and the delay of the switching process: m + max(d) a d b d c ).

[0099] Therefore, by fading out the playback algorithm modules from the first differential playback algorithm sequence and fading in the playback algorithm modules from the second differential playback algorithm sequence, the first playback algorithm sequence can be switched to the second playback algorithm sequence by processing only the differential playback algorithm sequence. This minimizes the number of playback algorithm modules that need to be processed during the switching process, reducing system resource consumption and avoiding insufficient computing resources on some terminals due to poor processor performance. It also shortens the switching time of the playback algorithm sequence.

[0100] In one exemplary embodiment, processing a first differential playback algorithm sequence to change the output audio data of the first differential playback algorithm sequence to be the same as the input audio data of the first differential playback algorithm sequence includes: obtaining a first playback parameter in each playback algorithm module of the first differential playback algorithm sequence, and adjusting the first playback parameter to change the output audio data of each playback algorithm module of the first differential playback algorithm sequence to be the same as the input audio data of each playback algorithm module of the first differential playback algorithm sequence.

[0101] When processing the first difference playback algorithm sequence, each playback algorithm module in the sequence can be processed individually. Each playback algorithm module may include at least one first playback parameter. A "fade-out operation" can be performed on each first playback parameter. A "fade-out operation" removes each playback algorithm module from the audio playback algorithm sequence, meaning the first playback parameter in each module no longer participates in the processing of audio data. For example, the first playback parameter can be adjusted to "fade out" the processing of audio data. For instance, the first playback parameter can be adjusted so that the output audio data of each playback algorithm module in the first difference playback algorithm sequence is changed to be the same as the input audio data of each playback algorithm module in the first difference playback algorithm sequence.

[0102] The adjustment rule can be any rule that adjusts the first playback parameter to prevent it from participating in audio data processing. For example, the adjustment of the first playback parameter can be described numerically to characterize its participation in audio data processing. For example, a value of 100 indicates that the first playback parameter fully participates in audio data processing, while a value of 0 indicates that the first playback parameter does not participate in audio data processing at all. A decreasing rule can be used to gradually reduce the first playback parameter's participation in audio data processing. For example, it can decrease according to a preset step size, such as from 100 to 0, with a step size of 1, then decreasing sequentially from 100, 99, 98, 97, ..., 1, 0 to 0, thus gradually reducing the first playback parameter's participation in audio data processing, so that the first playback parameter in the playback algorithm module no longer participates in audio data processing, and therefore the playback algorithm module no longer plays a role in processing audio data in the playback algorithm sequence.

[0103] According to the above rules, adjusting the first playback parameter can avoid audio data abrupt changes during the switching process. In addition, processing each playback algorithm module separately also ensures that the output of each playback algorithm module does not abruptly change.

[0104] In one exemplary embodiment, processing the second differential playback algorithm sequence to change the output audio data of the second differential playback algorithm sequence to the first preset output audio data includes: obtaining the second playback parameters in each playback algorithm module of the second differential playback algorithm sequence, and adjusting the second playback parameters to change the output audio data of each playback algorithm module of the second differential playback algorithm sequence to the first preset output audio data.

[0105] When processing the second difference playback algorithm sequence, each playback algorithm module in the sequence is processed individually. Each playback algorithm module may include at least one second playback parameter. A "fade-in" operation can be performed on each second playback parameter. The "fade-in" operation adds each playback algorithm module to the audio playback algorithm sequence, causing the second playback parameter in each module to participate in the processing of the audio data. For example, the second playback parameter can be adjusted to "fade in" and process the audio data. For example, the second playback parameter can be adjusted so that the output audio data of each playback algorithm module in the second difference playback algorithm sequence changes to match the first preset audio data.

[0106] The adjustment rules can be any rules that adjust the second playback parameter to ensure its full participation in audio data processing. For example, the adjustment of the second playback parameter can be numerically described to characterize its degree of participation in audio data processing. For instance, a value of 0 indicates that the second playback parameter does not participate in audio data processing at all, while a value of 100 indicates that the second playback parameter fully participates in audio data processing. An incremental rule can be used to gradually incorporate the second playback parameter into the audio data playback algorithm sequence. For example, it can be incremented according to a preset step size. For instance, when changing from 0 to 100, with a step size of 1, the parameter can be incremented sequentially from 0, 1, 2, 3, ..., 99, 100 to 100, thus gradually increasing the degree of participation of the second playback parameter in audio data processing. This ensures that the second playback parameter in the playback algorithm module fully participates in audio data processing, thereby enabling the playback algorithm module to play a role in processing audio data within the playback algorithm sequence.

[0107] According to the above rules, adjusting the second playback parameters can avoid audio data abrupt changes during the switching process. In addition, processing each playback algorithm module separately also ensures that the output of each playback algorithm module does not abruptly change.

[0108] In one exemplary embodiment, Figure 5 This is a flowchart illustrating a method for processing the same playback algorithm subsequence according to an exemplary embodiment, such as... Figure 5 As shown, it includes the following steps:

[0109] Step S501: Obtain the third playback parameter in each playback algorithm module of the corresponding first playback algorithm sequence in the same playback algorithm subsequence;

[0110] Step S502: Obtain the fourth playback parameter in each playback algorithm module of the corresponding second playback algorithm sequence in the same playback algorithm subsequence;

[0111] Step S503: Change the third playback parameter to the fourth playback parameter.

[0112] Although the first and second playback algorithm sequences include the same playback algorithm sub-sequences, the states required for algorithm processing by the algorithm differ between the currently playing audio data and the audio data to be switched. Therefore, the parameter values ​​for the same playback parameters in the same playback algorithm sub-sequences in the first and second playback algorithm sequences will differ. Consequently, the parameter values ​​for the corresponding parameters in the same playback algorithm sub-sequences in the first and second playback algorithm sequences are modified to match the parameter values ​​for the same playback parameters in the same playback algorithm sub-sequences in the second playback algorithm sequence, thus satisfying the audio data processing requirements of the playback algorithm sequence to be switched.

[0113] In the same playback algorithm subsequence, the third playback parameter in each playback algorithm module of the first playback algorithm sequence is the same as the fourth playback parameter in each playback algorithm module of the second playback algorithm sequence. Because the states that the currently playing audio data and the audio data to be switched require algorithm processing are different, the corresponding parameter values ​​of the third and fourth playback parameters are different. In one example, suppose that playback algorithm module A in the same playback algorithm sequence has a playback parameter 'a'. In the first playback algorithm sequence, the value of playback parameter 'a' (the third playback parameter) is 4, and in the second playback algorithm sequence, the value of playback parameter 'a' (the fourth playback parameter) is 8.

[0114] When changing the third playback parameter to the fourth playback parameter, based on the characteristics of the playback parameter, at least one of the following two cases should be included:

[0115] The first approach involves adjusting the playback parameters in a continuously variable manner when the parameter values ​​can be changed continuously. For example, the value of the third playback parameter can be gradually changed to the value of the fourth playback parameter according to a preset step size. For instance, if the third playback parameter is 4 and the fourth playback parameter is 8, it can be changed continuously in preset step sizes of 0.5. Therefore, the playback parameters can be adjusted continuously in the order of 4, 4.5, 5, 5.5, 6...7.5, 8 to change the third playback parameter to the fourth playback parameter, thus avoiding sudden changes in audio loudness during the switching process.

[0116] The second approach involves setting up two algorithm processing units within the playback algorithm module when the playback parameters are discrete and cannot change continuously. These units respectively set the third and fourth playback parameters. Linear interpolation between the two processing units transforms the third playback parameter into the fourth. In one example, the playback parameters can only be 1, 2, or 3, representing three audio data playback modes. The third playback parameter is 1, and the fourth is 2. In this case, a first and a second algorithm processing unit are set up within the playback module. Linear interpolation between these two units transforms the third playback parameter into the fourth, preventing sudden changes in audio loudness during switching.

[0117] The playback parameters in the playback algorithm modules within the same playback algorithm subsequence are adjusted to switch the same playback algorithm subsequence corresponding to the first playback algorithm sequence to the same playback algorithm subsequence corresponding to the second playback algorithm sequence. For the playback algorithm modules within the same playback algorithm subsequence, only the parameters are adjusted, reducing the computational load of switching playback algorithm sequences and shortening the switching time.

[0118] In one exemplary embodiment, switching from a first playback algorithm sequence to a second playback algorithm sequence includes: merging the processed first difference playback algorithm sequence, the second difference playback algorithm sequence, and the same playback algorithm subsequence to switch from the first playback algorithm sequence to the second playback algorithm sequence.

[0119] Based on the order of the playback algorithm modules in the first playback algorithm sequence and the order of the playback algorithm modules in the second playback algorithm sequence, the processed first difference playback algorithm sequence, second difference playback algorithm sequence, and identical playback algorithm subsequence are merged to switch to the second playback algorithm sequence.

[0120] In one example, such as Figure 6 As shown, the first playback algorithm sequence is (Algorithm A, Algorithm C, Algorithm D), the second playback algorithm sequence is (Algorithm B, Algorithm C, Algorithm A), the processed first difference playback algorithm sequence is (Algorithm D'), and the second difference playback algorithm sequence is (Algorithm B'). Algorithm B and Algorithm A are added to the first playback algorithm sequence according to their positions in the second playback algorithm sequence to obtain the playback algorithm sequence (Algorithm A, Algorithm B', Algorithm C, Algorithm D', Algorithm A). At this time, Algorithm B' is the newly added playback algorithm module, Algorithm D' is the playback algorithm module that no longer processes the audio data, and Algorithm A is the playback algorithm module whose position has been adjusted. Therefore, the second playback algorithm sequence (Algorithm B, Algorithm C, Algorithm A) is obtained.

[0121] In one exemplary embodiment, Figure 7 This is a flowchart illustrating step S303 of an exemplary embodiment, showing the method of switching the first playback algorithm sequence to the second playback algorithm sequence based on whether the first playback algorithm sequence and the second playback algorithm sequence include the same playback algorithm sub-sequence. Figure 7 As shown, it includes the following steps:

[0122] Step S701: If the first playback algorithm sequence and the second playback algorithm sequence do not include the same playback algorithm subsequence;

[0123] Step S702: Process the first playback algorithm sequence so that the output audio data of the first playback algorithm sequence is changed to be the same as the input audio data of the first playback algorithm sequence;

[0124] Step S703: Process the second playback algorithm sequence to change the output audio data of the second playback algorithm sequence to the second preset output audio data.

[0125] When the first playback algorithm sequence and the second playback algorithm sequence do not contain the same playback algorithm subsequence, the playback algorithm modules in the first playback algorithm sequence are all playback algorithm modules that need to be removed. Therefore, it is necessary to change the output audio data of the first playback algorithm sequence to be the same as the input audio data of the first playback algorithm sequence, and to perform a "fade-out operation" on each playback parameter in each playback algorithm module in the first playback algorithm sequence, adjusting all playback parameters so that all playback parameters in each playback algorithm module no longer participate in the processing of audio data.

[0126] The playback algorithm modules in the second playback algorithm sequence are all playback algorithm modules that need to be added to the playback algorithm sequence. Therefore, it is necessary to change the output audio data of the second playback algorithm sequence to the second preset output audio data. That is, the second playback algorithm sequence is used to process the audio data, and a "fade-in operation" is performed on each playback parameter in each playback algorithm module in the second playback algorithm sequence to adjust all playback parameters so that all playback parameters in each playback algorithm module participate in the processing of audio data.

[0127] It should be noted that steps S702 and S703 are performed separately for each playback algorithm module, so they can be processed according to preset rules or performed simultaneously, and this disclosure does not impose any restrictions.

[0128] By changing the output audio data of the first playback algorithm sequence to be the same as the input audio data of the first playback algorithm sequence, and changing the output audio data of the second playback algorithm sequence to the second preset output audio data, all playback algorithm modules in the first playback algorithm sequence are removed from the playback algorithm sequence for audio data playback, and all playback algorithm modules in the second playback algorithm sequence are added to the playback algorithm sequence for audio data playback.

[0129] In one exemplary embodiment, switching a first playback algorithm sequence to a second playback algorithm sequence includes: merging the processed first playback algorithm sequence and the processed second playback algorithm sequence to switch the first playback algorithm sequence to the second playback algorithm sequence.

[0130] Following the order of the playback algorithm modules in the second playback algorithm sequence, the processed first playback algorithm sequence and the processed second playback algorithm sequence are merged. The processed second playback algorithm sequence can be arranged after the processed first playback algorithm sequence or before the processed first playback algorithm sequence. Since the processed first playback algorithm sequence does not change the characteristics of the audio data, the order of the processed first playback algorithm sequence and the processed second playback algorithm sequence is not restricted.

[0131] In an exemplary embodiment of this disclosure, a first playback algorithm sequence of currently playing first audio data is obtained, a second playback algorithm sequence of second audio data to be switched is obtained, and the first playback algorithm sequence is switched to the second playback algorithm sequence based on whether the first playback algorithm sequence and the second playback algorithm sequence include the same playback algorithm sub-sequence. This can reduce resource consumption during the playback algorithm sequence switching process and shorten the switching time of the playback algorithm sequence, while avoiding the problem of uneven audio data loudness before and after the playback algorithm sequence switching.
