[0026] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0027] In related technologies, media data undergoes equalization processing during playback on the terminal to ensure balanced loudness. However, in actual playback, the loudness of some media data, even after equalization, may still not meet the user's needs, requiring the user to manually increase or decrease the volume, thus affecting the user experience.

[0028] Therefore, this disclosure provides a volume adjustment method that can effectively reduce the number of times volume adjustment is required when playing media data, thereby improving the playback effect of media data.

[0029] According to an embodiment of this disclosure, a volume adjustment method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0030] This embodiment provides a volume adjustment method that can be used in electronic devices such as mobile phones and tablets. Figure 1 This is a flowchart of a volume adjustment method according to an embodiment of the present disclosure, such as... Figure 1 As shown, the process includes the following steps:

[0031] Step S101: Based on the historical playback records of the target media data, determine the probability of adjusting the volume of the target media data to play at a preset volume.

[0032] The target media data can be understood as any media data that needs to be played. For example, the target media data can be audio or video that needs to be played. The playback history includes the volume adjustment records when the target media data was played in the past. The volume adjustment records are used to record the volume adjustments made during the past playback of the target media data. The preset volume can be the volume used when the target media data was played once or multiple times in the past playback history.

[0033] To determine whether volume adjustment is needed when the target media data is played at a preset volume, the volume adjustment status of the target media data in each past playback is determined based on the historical playback records of the target media data. This allows for targeted analysis to determine the probability of volume adjustment when the target media data is played at a preset volume, thereby improving the rationality and accuracy of subsequent preset volume adjustments.

[0034] Step S102: In response to the volume adjustment probability being greater than the first threshold, based on the volume adjustment record, determine the first probability of the preset volume being increased and the second probability of the preset volume being decreased.

[0035] The first threshold can be understood as the maximum probability value for determining that the preset volume does not need to be adjusted. When the volume adjustment probability is greater than the first threshold, it indicates that the volume will be adjusted when the target media data is played at that preset volume. Therefore, when the volume adjustment probability is determined to be greater than the first threshold, based on the volume adjustment records, a first probability of increasing the preset volume and a second probability of decreasing it are determined respectively. This allows for subsequent adjustments to the preset volume based on the comparison between the first and second probabilities, thereby improving the effectiveness of volume adjustment.

[0036] Step S103: Determine the target adjustment strategy based on the comparison result between the first probability and the second probability.

[0037] By comparing the first and second probabilities, the adjustment direction can be clearly defined, making the resulting target adjustment strategy more reasonable and effective. For example, if the first probability is greater than the second probability, it means that during the past playback of the target media data, the probability of the preset volume being increased is greater than the probability of the preset volume being decreased. Therefore, when determining the subsequent target adjustment strategy, an adjustment strategy that increases the preset volume should be adopted. If the first probability is less than the second probability, it means that during the historical playback of the target media data, the probability of the preset volume being increased is less than the probability of the preset volume being decreased. Therefore, when determining the subsequent target adjustment strategy, an adjustment strategy that decreases the preset volume should be adopted.

[0038] Step S104: Adjust the preset volume according to the target adjustment strategy to determine the playback volume of the target media data.

[0039] After determining the target adjustment strategy, the preset volume is adjusted according to the target adjustment strategy so that the volume of the target media data to be played is more in line with the playback expectation. This can effectively reduce the probability that the volume of the target media data will be adjusted during playback, thereby helping to improve the playback effect of the media data.

[0040] The volume adjustment method provided in this embodiment can identify the probability of volume adjustment when the target media data is played at a preset volume by using the historical playback records of the target media data. Then, when the volume adjustment probability is greater than a first threshold, based on the comparison between the first probability of the preset volume being increased and the second probability of it being decreased, an appropriate target adjustment strategy is adopted to adjust the preset volume in a targeted manner. This makes the obtained playback volume more in line with the playback expectation, reduces the probability of the target media data being adjusted during playback, and achieves the purpose of improving the playback effect of the media data.

[0041] This embodiment provides a volume adjustment method that can be used in the aforementioned electronic devices, such as mobile phones and tablet computers. Figure 2 This is a flowchart of a volume adjustment method according to an embodiment of the present disclosure, such as... Figure 2 As shown, the process includes the following steps:

[0042] Step S201: Based on the historical playback records of the target media data, determine the probability of adjusting the volume of the target media data to play at a preset volume.

[0043] Specifically, the historical playback record also includes the historical playback count of the target media data, and step S201 above includes:

[0044] Step S2011: Based on the volume adjustment record and the historical playback count, determine the first playback count of the target media data played at the preset volume and the second playback count of the preset volume being adjusted.

[0045] Volume adjustment records reveal the initial and adjusted volume of the target media data during each playback. Historical playback records show the total number of times the target media data has been played in the past; that is, the total number of times the target media data has been played historically. Historical playback counts refer to the cumulative number of times the target media data has been played on at least one playback device.

[0046] Since the volume used for each playback of the target media data may vary, to better understand the playback performance when the target media data is played at the preset volume, the following statistics are calculated based on volume adjustment records and historical playback counts: the first playback count when the target media data was played at the preset volume, and the second playback count during which the preset volume was adjusted. The second playback count is less than or equal to the first playback count.

[0047] Step S2012: Based on the first playback count and the second playback count, determine the probability of adjusting the volume of the target media data to be played at a preset volume.

[0048] Based on the comparison results of the first and second playback counts, the probability of volume adjustment when playing target media data at the preset volume can be clearly defined. This volume adjustment probability can quantify the likelihood that the preset volume needs to be adjusted, thereby making the process of determining the target adjustment strategy more convenient and efficient.

[0049] In some optional implementations, step S2012 above includes:

[0050] Step a1: Determine the total historical playback volume of media data played by the playback device and the total volume adjustment volume;

[0051] Step a2: Determine the total probability of volume adjustment corresponding to the playback device based on the ratio between the total volume adjustment and the total historical playback volume.

[0052] Step a3: Determine the playback probability of the target media data based on the ratio between the first playback count and the total historical playback count.

[0053] Step a4: Based on the ratio between the second playback count and the total volume adjustment, determine the third probability that the preset volume needs to be adjusted on the playback device;

[0054] Step a5: Based on the third probability, the total probability of volume adjustment, and the playback probability, determine the probability of volume adjustment when the target media data is played on the playback device at the preset volume.

[0055] Specifically, historical playback volume refers to the total number of media data played on the playback device in the past (PlayVolume, PV). The number of plays for each media data item must be at least 1, and the corresponding content is unlimited. Total volume adjustment volume refers to the total number of times the playback device adjusted the volume while playing media data in the past. In some optional examples, to ensure improved reliability of volume adjustment, both historical playback volume and total volume adjustment volume are statistically obtained from media data played on the playback device within a specified time period. For example, the specified time period could be within 30 days from the current time, or within 7 days from the current time. The time interval of the specified period can be determined according to requirements.

[0056] By comparing the total volume adjustment count with the total historical playback count, we can determine the probability that the playback device will adjust the volume while playing media data. This ratio can then be used to predict the total probability of the playback device adjusting the volume. For example, the total probability of volume adjustment P(c) can be expressed by the following formula: P(c) = Total volume adjustment count / Total historical playback count.

[0057] By calculating the ratio between the first playback count and the total historical playback count, we can determine the percentage of times the target media data has been played on the playback device in the past. This ratio can then be used to predict the probability of the target media data being played again on the playback device, thus obtaining the playback probability of the target media data. For example, the playback probability p(x) can be expressed by the following formula: p(x) = First playback count / Total historical playback count.

[0058] Based on the ratio between the second playback count and the total volume adjustment, the probability that the target media data will be played at the preset volume on the playback device and requires volume adjustment can be determined. This ratio can then be used as a third probability to predict the need to adjust the preset volume on the playback device. For example, the playback probability p(x|c) can be expressed by the following formula: p(x|c) = Second playback count / Total volume adjustment.

[0059] Based on the third probability, the total probability of volume adjustment, and the playback probability, the historical playback data of the target media data and the historical playback data of the playback device can be combined to comprehensively evaluate and analyze the probability of volume adjustment when the target media device plays at the preset volume on the playback device. This can effectively improve the reliability and accuracy of determining the volume adjustment probability.

[0060] In some optional examples, the process of determining the volume adjustment probability includes: determining the product between the total volume adjustment probability and the third probability, and using the quotient between the product and the playback probability as the volume adjustment probability of playing the target media data at a preset volume on the playback device. That is, the volume adjustment probability p(c|x) can be determined based on Bayes' theorem using the following formula: p(c|x) = p(x|c)P(c) / p(x). Determining the volume adjustment probability through this process reduces the influence of subjective factors, making the determination of the volume adjustment probability more objective and scientific, thereby helping to improve the rationality and accuracy of subsequent volume adjustments.

[0061] In some optional implementation scenarios, since P(c) = total volume adjustment / total historical playback, p(x) = first playback count / total historical playback, p(x|c) = second playback count / total volume adjustment, and p(c|x) = p(x|c)P(c) / p(x), the formula for determining the volume adjustment probability p(c|x) can be simplified to: p(c|x) = second playback count / first playback count. Therefore, when the first playback count and the second playback count are determined, the volume adjustment probability can be obtained quickly, thereby effectively improving the determination efficiency.

[0062] In other alternative examples, the volume adjustment probability can be determined by a pre-built deep learning model based on the third probability of the input, the total probability of volume adjustment, and the probability of playback. This can effectively reduce the need for manual intervention and analysis, thereby helping to improve the efficiency of determining the volume adjustment probability.

[0063] Step S202: In response to the volume adjustment probability being greater than a first threshold, based on the volume adjustment records, determine a first probability of the preset volume being increased and a second probability of it being decreased. For details, please refer to [link to relevant documentation]. Figure 1 Step S102 of the illustrated embodiment will not be described again here.

[0064] Step S203: Based on the comparison between the first probability and the second probability, determine the target adjustment strategy. For details, please refer to [link to relevant documentation]. Figure 1 Step S103 of the illustrated embodiment will not be described again here.

[0065] Step S204: Adjust the preset volume according to the target adjustment strategy to determine the playback volume of the target media data. For details, please refer to [link to relevant documentation]. Figure 1 Step S104 of the illustrated embodiment will not be described again here.

[0066] The volume adjustment method provided in this embodiment determines the volume adjustment probability by analyzing volume adjustment records and historical playback counts. This quantifies the likelihood that volume adjustment is required when playing target media data. Then, based on the comparison between the volume adjustment probability and a first threshold, a target adjustment strategy is determined. This makes the determined target adjustment strategy more reasonable and reliable, thereby effectively improving the playback effect of the target media data.

[0067] In some optional examples, the process of determining the first probability can be as follows: Based on the volume adjustment records, playback records where the target media data was played at a preset volume during historical playback can be selected. Then, based on these playback records, the number of times the preset volume was increased can be counted, thus obtaining the first adjustment quantity. The ratio between the first adjustment quantity and the first playback count is taken as the first probability. Similarly, when determining the second probability, based on the playback records, the number of times the preset volume was decreased can be counted, thus obtaining the second adjustment quantity. The ratio between the second adjustment quantity and the first playback count is taken as the second probability.

[0068] In some optional implementations, the process of determining the target adjustment strategy based on the comparison between the first probability and the second probability includes: if the first difference between the first probability and the second probability is greater than a second threshold, then the target adjustment strategy is determined to be the first adjustment strategy. The second threshold can be understood as a threshold for determining whether volume increase processing is needed. The specific value of the second threshold can be set according to requirements; for example, the second threshold can be 0.4 or 0.5. When the first difference between the first probability and the second probability is greater than the second threshold, it indicates that during historical playback of the target media data, when played at a preset volume, the preset volume is mostly adjusted by increasing the volume to alleviate the problem of insufficient volume provided by the preset volume affecting the auditory effect. Therefore, the first adjustment strategy for increasing the preset volume is selected as the target adjustment strategy so that subsequent volume adjustments can increase the preset volume to meet playback expectations, thereby improving the playback effect of the target media data.

[0069] In some alternative implementations, if the target adjustment strategy is the first adjustment strategy, the preset volume is adjusted according to the target adjustment strategy to determine the playback volume of the target media data, including: determining the maximum value of the dynamic range control curve according to the first adjustment strategy, and adjusting the preset volume based on the maximum value to obtain the playback volume of the target media data.

[0070] Specifically, the maximum value of the Dynamic Range Control (DRC) curve is determined according to the first adjustment strategy. Dynamic Range Control is a method of adjusting volume by compressing or expanding the dynamic range of an audio signal. To maximize the preset volume, the maximum value of the DRC curve is determined, and this maximum value is used to specifically adjust the preset volume, ensuring that the playback volume of the target media data meets playback expectations.

[0071] In some alternative implementations, the process of determining the target adjustment strategy based on the comparison between the first probability and the second probability further includes: if the first difference between the first probability and the second probability is less than or equal to a second threshold, then the target adjustment strategy is determined based on the second difference between the second probability and the first probability. If the first difference between the first probability and the second probability is less than or equal to the second threshold, it indicates that during historical playback of the target media data, the preset volume was not frequently adjusted by increasing the volume. Therefore, to determine whether the preset volume was frequently adjusted by decreasing the volume during historical playback, the target adjustment strategy is determined based on the second difference between the second probability and the first probability, thereby improving the accuracy of determining the target adjustment strategy.

[0072] In some optional examples, if the second difference is greater than the third threshold, the target adjustment strategy is determined to be the second adjustment strategy, which is used to reduce the preset volume; if the second difference is less than or equal to the third threshold, the target adjustment strategy is determined to be the third adjustment strategy, which is used to compress the dynamic range control curve and adjust the preset volume based on the compressed dynamic range control curve.

[0073] Specifically, the third threshold can be understood as the threshold for determining whether volume reduction processing is needed. The specific value of the third threshold can be set according to requirements; for example, the third threshold can be 0.2 or 0.3. If the second difference is greater than the third threshold, it indicates that during the historical playback of the target media data, when played at the preset volume, the preset volume is mostly adjusted by reducing the volume to alleviate the problem of excessive volume affecting the listening effect. Therefore, the second adjustment strategy for reducing the preset volume is selected as the target adjustment strategy so that when the preset volume is adjusted according to the second adjustment strategy, the preset volume can be effectively reduced to meet the playback expectations. For example, the second adjustment strategy can refer to reducing the preset volume by adjusting the limit makeup gain or DRC compensation gain. Preferably, the limit makeup gain or DRC compensation gain can be adjusted by setting it to zero or adjusting the weight to achieve the purpose of reducing the preset volume, avoiding the situation where the audio signal is too strong or distorted due to excessive compensation gain, thereby improving the stability of volume adjustment.

[0074] If the second difference is less than or equal to the third threshold, it indicates that during the historical playback of the target media data, the preset volume may have increased or decreased. Therefore, the third adjustment strategy is selected as the target adjustment strategy to ensure a more stable playback volume when adjusting the preset volume according to the third adjustment strategy. Specifically, the third adjustment strategy compresses the dynamic range control curve and adjusts the preset volume based on the compressed dynamic range control curve, effectively preventing volume fluctuations during adjustment. This can improve the listening experience of the target media data to a certain extent, making the sound playback clearer and more comfortable, thus enhancing the playback quality of the target media data.

[0075] Determining the target adjustment strategy based on the comparison between the second difference and the third threshold allows for more flexible adaptation to different playback situations, improving the quality and effect of media data playback and meeting playback expectations.

[0076] This embodiment provides a volume adjustment method that can be used in electronic devices such as mobile phones and tablets. Figure 3 This is a flowchart of a volume adjustment method according to an embodiment of the present disclosure, such as... Figure 3 As shown, the process includes the following steps:

[0077] Step S301: Based on the historical playback records of the target media data, determine the probability of adjusting the volume of the target media data to play at a preset volume.

[0078] Step S302: In response to the volume adjustment probability being greater than the first threshold, based on the volume adjustment record, determine the first probability of the preset volume being increased and the second probability of the preset volume being decreased.

[0079] Step S303: Determine the target adjustment strategy based on the comparison result between the first probability and the second probability.

[0080] Step S304: Adjust the preset volume according to the target adjustment strategy to determine the playback volume of the target media data.

[0081] Step S305: In response to the volume adjustment probability being less than or equal to the first threshold, loudness equalization processing is performed on the target media data to determine the playback volume of the target media data.

[0082] In response to a volume adjustment probability less than or equal to a first threshold, indicating that the target media data has a low probability of volume adjustment when played at a preset volume during historical playback, loudness equalization is performed on the target media data to further optimize the audio effect of the target media data and obtain the playback volume of the target media data.

[0083] The volume adjustment method provided in this embodiment, after determining the probability of playing the target media data at a preset volume, uses different methods to determine the volume to be played of the target media data based on the comparison result of the volume adjustment probability and a first threshold. This makes the volume adjustment method more flexible and targeted, thereby effectively improving the playback quality of the target media data, reducing the probability of manual adjustment, and meeting the user's expectations.

[0084] As one or more specific application embodiments of this disclosure, the process of determining the playback volume of target media data is as follows: Figure 4 As shown, the specific process is as follows:

[0085] First, based on the historical playback records of the target media data, determine the probability of adjusting the volume of the target media data to play at the preset volume.

[0086] Secondly, given the determined volume adjustment probability, the volume adjustment probability is compared with a first threshold to determine whether the volume adjustment probability is greater than the first threshold.

[0087] If the volume adjustment probability is less than or equal to the first threshold, then loudness equalization processing is performed on the target media data to determine the playback volume of the target media data.

[0088] If the volume adjustment probability is greater than a first threshold, then based on the volume adjustment records during historical playback of the target media data, a first probability of increasing the preset volume and a second probability of decreasing the preset volume are determined. It is then determined whether a first difference between the first and second probabilities is greater than a second threshold. If the first difference is greater than the second threshold, the target adjustment strategy is determined to be the first adjustment strategy. According to the first adjustment strategy, the maximum value of the dynamic range control curve is determined, and the preset volume is adjusted based on this maximum value. The adjusted preset volume is then used to update the parameters for processing the target media data, and the updated parameters are used for loudness equalization processing to determine the playback volume of the target media data.

[0089] If the first difference between the first probability and the second probability is less than or equal to the second threshold, then it is determined whether the second difference between the second probability and the first probability is greater than the third threshold. If the second difference between the second probability and the first probability is greater than the third threshold, then the target adjustment strategy is determined to be the second adjustment strategy. According to the second adjustment strategy, the preset volume is reduced by adjusting the limit makeup gain or DRC compensation gain. Then, the adjusted preset volume is used to update the parameters for processing the target media data, and the updated parameters are used for loudness equalization processing to determine the playback volume of the target media data.

[0090] If the second difference between the second probability and the first probability is less than or equal to the third threshold, then the target adjustment strategy is determined to be the third adjustment strategy. According to the third adjustment strategy, the dynamic range control curve is compressed, and the preset volume is adjusted based on the compressed dynamic range control curve. Then, the adjusted preset volume is used to update the parameters for processing the target media data, and the updated parameters are used for loudness equalization processing, thereby determining the playback volume of the target media data.

[0091] Adjusting volume in the above way makes the process more scientific and targeted, resulting in a higher volume of the target media data that is more in line with expectations, and thus helps to improve the playback quality and effect of the target media data.

[0092] As another specific application embodiment of the present disclosure, the target adjustment strategy may be obtained through a preset volume adjustment module. Figure 5The process flow for processing target media data is illustrated, which can include a parameter preparation stage and a streaming processing stage. The preparation stage includes determining the loudness gain, determining the parameters of the DRC curve, and determining the loudness compensation gain. Based on the target adjustment strategy determined by the volume adjustment module, the loudness gain, the parameters for determining the DRC curve, and the loudness compensation gain in the preparation stage can be specifically adjusted to ensure that the loudness gain processing of the target media data in the streaming processing stage is more reasonable and the auditory effect better meets expectations.

[0093] The streaming processing stage includes: applying loudness gain to the target media data to obtain the first media data; obtaining the DRC curve using the parameters of the DRC curve, and then applying the DRC curve to the first media data for dynamic range control to obtain the second media data; applying loudness compensation gain to the second media data to obtain the third media data; and finally, applying peak limiting to the third media data to obtain the target media data.

[0094] This embodiment also provides a volume adjustment device for implementing the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, hardware implementations, or a combination of software and hardware, are also possible and contemplated.

[0095] This embodiment provides a volume adjustment device, such as... Figure 6 As shown, it includes:

[0096] The first processing module 601 is used to determine the volume adjustment probability of playing the target media data at a preset volume based on the historical playback records of the target media data. The historical playback records include the volume adjustment records when the target media data was played in the past.

[0101] The first statistical unit is used to determine the first number of times the target media data is played at a preset volume and the second number of times the preset volume is adjusted, based on the volume adjustment record and the historical playback count. The second playback count is less than or equal to the first playback count.

[0102] The second statistical unit is used to determine the probability of adjusting the volume of the target media data to be played at a preset volume based on the first playback count and the second playback count.

[0103] In some alternative implementations, the second statistical unit includes:
