In one embodiment, the digital audio signal decoded by the audio decoder may be sampled to obtain amplitude information within a preset time period T. In an embodiment, the amplitude information may be composed of a plurality of amplitude values, and the amplitude curves of the sound sources played during the preset time period T may be correspondingly determined according to the obtained plurality of amplitude values. In another embodiment, taking the Android system as an example, the audio information of the audio source can be obtained by the android.media.MediaRecorder class or the android.media.AudioRecord class to obtain the amplitude of the audio amplitude corresponding to the audio information. In another embodiment, when the audio information acquired in step 101 is the original file corresponding to the sound source, the amplitude of the audio amplitude corresponding to the audio information may be obtained by parsing the original file.
在一个实施例中，当检测音源播放时，每隔预设时间(如1s、3s或10s)确定一次振幅，或者实时地对音频信息的每一帧音频帧的振幅进行确定。在一实施例中，所述获取所述音源的音频信息包括：获取所述音源的音频帧信息；依据所述音频信息确定所述音频信息对应的音频振幅包括：依据所述音频帧信息确定所述音频帧信息中每一帧音频帧的音频振幅。在一实施例中，当检测到音源播放时，对音源文件进行解析得到音频帧序列，根据音频帧序列的每一帧确定每一帧对应的振幅。In one embodiment, when detecting the sound source playing, the amplitude is determined once every preset time (eg, 1 s, 3 s, or 10 s), or the amplitude of each frame of the audio information of the audio information is determined in real time. In an embodiment, the acquiring the audio information of the sound source includes: acquiring audio frame information of the sound source; determining the audio amplitude corresponding to the audio information according to the audio information, comprising: determining, according to the audio frame information, The audio amplitude of each frame of the audio frame information. In an embodiment, when the sound source is detected, the sound source file is parsed to obtain an audio frame sequence, and the amplitude corresponding to each frame is determined according to each frame of the audio frame sequence.
步骤103、确定和所述音频振幅对应的振幅调整系数，将所述振幅调整系数划分为预设数目的子振幅调整系数，依据所述子振幅调整系数对所述音频振幅进行调整。Step 103: Determine an amplitude adjustment coefficient corresponding to the audio amplitude, divide the amplitude adjustment coefficient into a preset number of sub-amplitude adjustment coefficients, and adjust the audio amplitude according to the sub-amplitude adjustment coefficient.
在一个实施例中，为提高音源中低振幅区域的音量，对低振幅的音频振幅分配较大的振幅调整系数，高振幅的音频振幅相应的分配一较小的振幅调整系数。例如，对振幅大小小于-3分贝(db)且大于-10db音频振幅分配振幅调整系数为1.2，对振幅大小小于-10db且大于-50db的音频振幅分配振幅调整系数为2。 此时，在音源播放过程中，如果前一段音频振幅的振幅调整系数为1.2，而过渡到相邻的下一段音频振幅需要振幅调整系数为2的话，进行调整后的音频振幅会存在明显的听感突兀的问题，这是由振幅调整系数的跳跃带来的。In one embodiment, to increase the volume of the low amplitude region of the sound source, a large amplitude adjustment factor is assigned to the low amplitude audio amplitude, and a high amplitude audio amplitude is correspondingly assigned a smaller amplitude adjustment factor. For example, the amplitude adjustment coefficient is 1.2 for an amplitude amplitude of less than -3 decibels (db) and greater than -10 db, and the amplitude adjustment coefficient is 2 for an audio amplitude having an amplitude of less than -10 db and greater than -50 db. At this time, during the sound source playing, if the amplitude adjustment coefficient of the previous audio amplitude is 1.2, and the amplitude of the adjustment to the adjacent next audio amplitude requires an amplitude adjustment coefficient of 2, the adjusted audio amplitude will be clearly heard. A sudden problem, which is caused by the jump of the amplitude adjustment factor.
在一实施例中，所述将所述振幅调整系数划分为预设数目的子振幅调整系数包括：检测到不同音频振幅对应的振幅调整系数满足预设条件时，将所述振幅调整系数划分为预设数目的子振幅调整系数。在一实施例中，所述子振幅调整系数为依据所述振幅调整系数线性或非线性划分得到。In an embodiment, the dividing the amplitude adjustment coefficient into a preset number of sub-amplitude adjustment coefficients comprises: when detecting that an amplitude adjustment coefficient corresponding to different audio amplitudes satisfies a preset condition, dividing the amplitude adjustment coefficient into A preset number of sub-amplitude adjustment factors. In an embodiment, the sub-amplitude adjustment coefficients are obtained by linear or non-linear division of the amplitude adjustment coefficients.
在一实施例中，该预设条件可以是相邻的音频振幅的振幅调整系数不一样，例如振幅调整系数由前一音频振幅的振幅调整系数1变成(跳跃为)后一音频振幅的振幅调整系数2，或振幅调整系数由2变成1.2等此时，可以在相邻的两个音频振幅对应的两个振幅调整系数之间增加预设数目的子振幅调整系数。例如，当确定出的相邻音频振幅的振幅调整系数为1.2和2时，可在1.2到2之间再增加9个子振幅调整系数，即从1.2开始依次递增相同或不同的数值得到：1.28、1.36、1.42、...、1.92。在调节过程中，在振幅调整系数从1.2到2的过渡阶段，可将每n(例如，n大于1小于等于20)帧音频帧对应一个子振幅调整系数，依次对每一音频帧的振幅进行调整。例如，振幅调整系数由1.2改变为2时，改变开始时的第1-20帧音频帧对应的子振幅调整系数为1.28，第21-40帧音频帧对应的子振幅调整系数为1.36，依次类推。在该实施例中，假设振幅调整系数为1.2的前100帧音频帧已调整完成，从第101帧开始需要使用振幅调整系数2来调整，那么每20帧对应一级子振幅调整系数的话，从101帧开始的180帧，即到第280帧音频帧完成用子振幅调整系数调整音频帧的过渡阶段，从第281帧音频帧开始可以使用振幅调整系数2来调整，从而避免明显的听感突兀问题。In an embodiment, the preset condition may be that the amplitude adjustment coefficients of the adjacent audio amplitudes are different. For example, the amplitude adjustment coefficient is changed from the amplitude adjustment coefficient 1 of the previous audio amplitude to (the amplitude of the latter audio amplitude). When the adjustment coefficient is 2, or the amplitude adjustment coefficient is changed from 2 to 1.2, etc., a preset number of sub-amplitude adjustment coefficients can be added between the two amplitude adjustment coefficients corresponding to the adjacent two audio amplitudes. For example, when the amplitude adjustment coefficients of the determined adjacent audio amplitudes are 1.2 and 2, an additional 9 sub-amplitude adjustment coefficients may be added between 1.2 and 2, that is, the same or different values are sequentially incremented from 1.2 to obtain: 1.28, 1.36, 1.42, ..., 1.92. During the adjustment process, in the transition phase of the amplitude adjustment coefficient from 1.2 to 2, each n (for example, n is greater than 1 and less than or equal to 20) frame audio frames may be corresponding to one sub-amplitude adjustment coefficient, and the amplitude of each audio frame is sequentially performed. Adjustment. For example, when the amplitude adjustment coefficient is changed from 1.2 to 2, the sub-amplitude adjustment coefficient corresponding to the 1-20th audio frame at the start of the change is 1.28, and the sub-amplitude adjustment coefficient corresponding to the 21-40th audio frame is 1.36, and so on. . In this embodiment, it is assumed that the first 100 frames of audio frames whose amplitude adjustment coefficient is 1.2 have been adjusted, and the amplitude adjustment coefficient 2 needs to be adjusted from the 101st frame. Then, if every 20 frames corresponds to the first-level sub-amplitude adjustment coefficient, 180 frames from the beginning of 101 frames, that is, to the 280th frame, the audio frame is completed with the sub-amplitude adjustment coefficient to adjust the transition period of the audio frame, and the amplitude adjustment coefficient 2 can be adjusted from the 281-frame audio frame to avoid obvious hearing acuity. problem.
在一实施例中，对音频振幅进行调整的过程可以是：对音源文件进行解析，对得到的音频数据中的表征振幅信息的数据进行修改，修改完毕后再进行封装，当缓冲到对应的音源文件并被播放时音频振幅相应的已被增大；还可以是，在音源播放的解码过程中，通过对得到的数字音频信号进行分析得到音频振幅，将该振幅数据乘以对应的振幅调整系数以改变振幅大小，进而对音源的音量进行调节。In an embodiment, the process of adjusting the audio amplitude may be: parsing the audio file, modifying the data representing the amplitude information in the obtained audio data, and then performing the encapsulation after the modification, when buffering to the corresponding audio source. When the file is played, the audio amplitude is correspondingly increased; or, in the decoding process of the sound source playing, the audio amplitude is obtained by analyzing the obtained digital audio signal, and the amplitude data is multiplied by the corresponding amplitude adjustment coefficient. To change the amplitude, adjust the volume of the source.
由此，本实施例提供的方案实现了在不改变终端设备***原有音量的前提下对音源音量的大小进行了调节，调节过程可以在音源文件未进入缓冲区前，以减少播放负载，也可以是针对缓冲区中的音源内容进行调节以提高调节效率，从而提高了音量调节效率，降低了终端设备的功耗，且通过使用子振幅调整系数对预设数量的音频帧的音频振幅进行调整，避免了由振幅调整系数的跳跃带来的听感突兀的问题，提高了用户体验。Therefore, the solution provided in this embodiment realizes that the volume of the sound source is adjusted without changing the original volume of the terminal device system, and the adjustment process can reduce the playback load before the sound source file does not enter the buffer. It can adjust the sound source content in the buffer to improve the adjustment efficiency, thereby improving the volume adjustment efficiency, reducing the power consumption of the terminal device, and adjusting the audio amplitude of the preset number of audio frames by using the sub-amplitude adjustment coefficient.

The start time of c, for example, the amplitude adjustment coefficient i has been used to adjust the 101-300 frame audio frame, if the audio amplitude C corresponds to the amplitude adjustment coefficient k and the audio amplitude B pair The amplitude adjustment coefficient j is different. For example, if k is smaller than j, 10 sub-amplitude adjustment coefficients are added between the amplitude adjustment coefficient j and the amplitude adjustment coefficient k, and the 10 sub-amplitude adjustment coefficients are respectively successively decreasing k1, k2, ... , k10, starting from the 301st frame audio frame, each 10 frames of audio frames corresponding to a sub-amplitude adjustment coefficient, and using the sub-amplitude adjustment coefficient k1 to adjust the 301-310 frame audio frame, using the amplitude adjustment coefficient k2 for the 311th - 320 frames of audio frames are adjusted until the 391-400-frame audio frame is adjusted using the amplitude adjustment factor k10, and then adjusted from the 401-frame audio frame using the amplitude adjustment coefficient k.
由此，在不改变终端设备***原有音量的前提下对音源音量的大小进行了调节，提高了音量调节的效率，降低了终端设备的功耗，且通过使用子振幅调整系数对预设数量的音频帧进行调整，可避免由振幅调整系数的跳跃带来的听感突兀的问题，提高用户体验。Thereby, the volume of the sound source is adjusted without changing the original volume of the terminal device system, thereby improving the efficiency of the volume adjustment, reducing the power consumption of the terminal device, and using the sub-amplitude adjustment coefficient to the preset number.

图3是本公开另一实施例提供的一种音量调节方法的流程图。在一实施例中，所述确定和所述音频振幅对应的振幅调整系数包括：依据所述音频振幅的大小确定和所述音频振幅对应的振幅调整系数。如图3所示，本实施例提供的技术方案如下：FIG. 3 is a flowchart of a volume adjustment method according to another embodiment of the present disclosure. In an embodiment, the determining an amplitude adjustment coefficient corresponding to the audio amplitude comprises: determining an amplitude adjustment coefficient corresponding to the audio amplitude according to a magnitude of the audio amplitude. As shown in FIG. 3, the technical solution provided by this embodiment is as follows:
步骤310、当检测到终端设备进行音源播放时，获取所述音源的音频信息。Step 310: Acquire audio information of the sound source when detecting that the terminal device performs sound source playing.
步骤320、依据所述音频信息确定所述音频信息对应的音频振幅。Step 320: Determine an audio amplitude corresponding to the audio information according to the audio information.
步骤330、依据所述音频振幅的振幅大小确定和所述音频振幅对应的振幅调整系数。Step 330: Determine an amplitude adjustment coefficient corresponding to the audio amplitude according to the amplitude of the audio amplitude.
在一个实施例中，可通过获取预设长度的音频振幅确定该预设长度的音频振幅的平均振幅大小，进而依据该平均振幅大小确定该预设长度的音频振幅对应的振幅调整系数。在一实施例中，可通过预存的映射关系表确定平均振幅对应的振幅调整系数，如下表1所示：In an embodiment, the average amplitude of the audio amplitude of the preset length may be determined by acquiring an audio amplitude of a preset length, and then determining an amplitude adjustment coefficient corresponding to the audio amplitude of the preset length according to the average amplitude. In an embodiment, the amplitude adjustment coefficient corresponding to the average amplitude can be determined by a pre-stored mapping relationship table, as shown in Table 1 below:
表1Table 1
平均振幅Average amplitude 振幅调整系数Amplitude adjustment factor
大于-3db或小于-50dbGreater than -3db or less than -50db 11
小于-10db且大于-50dbLess than -10db and greater than -50db 22
小于-3db且大于-10dbLess than -3db and greater than -10db 1.51.5
如表1所示，当平均振幅大于-3db或小于-50db时，不对音频振幅进行调节；当振幅小于-3db且大于-10db时，振幅属于高振幅区，为该振幅分配振幅调整系数为1.5，当振幅小于-10db且大于-50db时，属于中振幅区，为该振幅分配振幅调整系数为2，以显著提高中振幅区的振幅大小。As shown in Table 1, when the average amplitude is greater than -3 db or less than -50 db, the audio amplitude is not adjusted; when the amplitude is less than -3 db and greater than -10 db, the amplitude belongs to the high amplitude region, and the amplitude distribution coefficient is 1.5 for the amplitude. When the amplitude is less than -10 db and greater than -50 db, it belongs to the middle amplitude region, and the amplitude adjustment coefficient is 2 for the amplitude to significantly increase the amplitude of the medium amplitude region.
步骤340、将所述振幅调整系数划分为预设数目的子振幅调整系数，依据所述子振幅调整系数对所述音频振幅进行调整。即，通过上述举例可知，将产生跳跃的两个相邻振幅调整系数之间增加多个子振幅调整系数，并在对音频帧的振幅进行调整所需使用的振幅调整系数发生改变时，逐级使用子振幅调整系数对预设数量的音频帧进行逐级调整。Step 340: The amplitude adjustment coefficient is divided into a preset number of sub-amplitude adjustment coefficients, and the audio amplitude is adjusted according to the sub-amplitude adjustment coefficient. That is, as can be seen from the above example, a plurality of sub-amplitude adjustment coefficients are added between two adjacent amplitude adjustment coefficients that generate a jump, and the amplitude adjustment coefficient used to adjust the amplitude of the audio frame is changed stepwise. The sub-amplitude adjustment factor adjusts the preset number of audio frames step by step.
由上述可知，通过对不同振幅大小的音频振幅分配不同的振幅调整系数，避免了破音的同时，降低了对噪音的振幅提升；而且在此基础上，进一步对相邻的音频振幅对应的不同的振幅调整系数进行细分后，对音频振幅中预设数量音频帧进行逐级调整，可以使得音源播放过程中的声音大小合理，听感平滑。It can be seen from the above that by assigning different amplitude adjustment coefficients to the amplitudes of the audio of different amplitudes, the amplitude of the noise is reduced while the sound is broken, and on the basis of this, the difference of the adjacent audio amplitudes is further After the amplitude adjustment coefficient is subdivided, the preset number of audio frames in the audio amplitude is adjusted step by step, which can make the sound in the sound source playing sound reasonable and the sense of hearing smooth.

在一实施例中，可依据终端设备的音量信息确定多个振幅调整系数，例如依据终端设备的音量信息确定了第一振幅调整系数、第二振幅调整系数和第三振幅调整系数，其中，第一振幅调整系数小于第二振幅调整系数，第二振幅调整系数小于第三振幅调整系数，然后依据音频振幅的振幅大小确定每个音频振幅对应三个振幅调整系数中的哪个振幅调整系数，例如为大于第一预设阈值或小于第三预设阈值的音频振幅分配第一振幅调整系数，为小于或等于第一预设阈值且大于第二预设阈值的音频振幅分配第二振幅调整系数，为小于或等于第二预设阈值且大于第三预设阈值的音频振幅分配第三振幅调整系数，其中，第一预设阈值大于第二预设阈值，第二预设阈值大于第三预设阈值，则如果某一音频振幅的振幅大小小于第三预设阈值，则确定该音频振幅对应的振幅调整系数为第一振幅调整系数。In an embodiment, a plurality of amplitude adjustment coefficients may be determined according to volume information of the terminal device, for example, determining a first amplitude adjustment coefficient, a second amplitude adjustment coefficient, and a third amplitude adjustment coefficient according to volume information of the terminal device, where An amplitude adjustment coefficient is smaller than the second amplitude adjustment coefficient, and the second amplitude adjustment coefficient is smaller than the third amplitude adjustment coefficient, and then according to the amplitude of the audio amplitude, which of the three amplitude adjustment coefficients is corresponding to each audio amplitude, for example, And an audio amplitude that is greater than the first preset threshold or less than the third preset threshold, the first amplitude adjustment coefficient is allocated, and the second amplitude adjustment coefficient is allocated to the audio amplitude that is less than or equal to the first preset threshold and greater than the second preset threshold. And a third amplitude adjustment coefficient is allocated to the audio amplitude that is less than or equal to the second preset threshold and greater than the third preset threshold, where the first preset threshold is greater than the second preset threshold, and the second preset threshold is greater than the third preset threshold And if the amplitude of the amplitude of the audio amplitude is less than the third preset threshold, determining the audio amplitude corresponding to A first amplitude adjustment factor is an amplitude adjustment coefficient.
在一实施例中，确定和所述音频振幅对应的振幅调整系数方式可以是：为大于第一预设阈值或小于第三预设阈值的音频振幅分配第一振幅调整系数，为小于或等于第一预设阈值且大于第二预设阈值的音频振幅分配第二振幅调整系数，为小于或等于第二预设阈值且大于第三预设阈值的音频振幅分配第三振幅调整系数，其中，所述第一振幅调整系数小于所述第二振幅调整系数，所述第二振幅调整系数小于所述第三振幅调整系数。在一实施例中，该第一预设阈值可以是-3db，第二预设阈值可以是-10db，第三预设阈值可以是-50db。在一实施例中，第一振幅调整系数为1(即不进行调整)，第二振幅调整系数为1.4，第三振幅调整系数为1.8。其中，对于振幅过大(例如，大于-3db)或振幅过小(例如，小于-50db)的音频振幅不进行振幅调节，避免了对过大振幅调节后造成的破音，也避免了对过小的噪音进行调高带来的杂音增强的问题，进一步优化了音量调节方法。In an embodiment, determining an amplitude adjustment coefficient corresponding to the audio amplitude may be: assigning a first amplitude adjustment coefficient to an audio amplitude greater than a first preset threshold or less than a third preset threshold, being less than or equal to the first a second amplitude adjustment coefficient is allocated to the audio amplitude of the preset threshold and greater than the second preset threshold, and the third amplitude adjustment coefficient is allocated to the audio amplitude that is less than or equal to the second preset threshold and greater than the third preset threshold, where The first amplitude adjustment coefficient is smaller than the second amplitude adjustment coefficient, and the second amplitude adjustment coefficient is smaller than the third amplitude adjustment coefficient.

在一个实施例中，可通过功放芯片检测终端设备中安装的播放器件(如：扬声器)的阻抗值，还可以是通过物理方式检测播放器件的阻抗。在一实施例中，该阻抗值越大，对应的对振幅调整系数的调整越大。例如，假设播放器件的标称阻抗值为x，通过检测得到的阻抗值为1.2x，则相应的在确定出的振幅调整系数的基础上，将该振幅调整系数乘以1.2作为调整后的振幅调整系数。In one embodiment, the impedance value of the playback device (eg, speaker) installed in the terminal device may be detected by the power amplifier chip, or the impedance of the playback device may be physically detected. In an embodiment, the greater the impedance value, the greater the adjustment to the amplitude adjustment factor. For example, assuming that the nominal impedance value of the playback device is x and the impedance value obtained by the detection is 1.2x, the amplitude adjustment coefficient is multiplied by 1.2 as the adjusted amplitude based on the determined amplitude adjustment coefficient. Adjustment coefficient.
步骤404、将调整后的振幅调整系数划分为预设数目的子振幅调整系数，依据所述子振幅调整系数对所述音频振幅进行调整。Step 404: Divide the adjusted amplitude adjustment coefficient into a preset number of sub-amplitude adjustment coefficients, and adjust the audio amplitude according to the sub-amplitude adjustment coefficient.
由上述可知，在对音源的振幅进行调节过程中，引入播放器件的阻抗值作为确定振幅调整系数的参量之一，避免了播放器件随播放时长的增加，阻抗值越来越高，导致对正常播放过程中的音量大小产生影响的问题，使得调节后的音量大小更佳符合用户需求，进一步提高了音量调节效果。It can be seen from the above that in the process of adjusting the amplitude of the sound source, the impedance value of the playback device is introduced as one of the parameters for determining the amplitude adjustment coefficient, thereby avoiding the increase of the playing device with the playing time, and the impedance value is getting higher and higher, resulting in normal The volume of the playback process has an impact problem, so that the adjusted volume is better in accordance with the user's needs, further improving the volume adjustment effect.

In an embodiment, after determining the amplitude adjustment coefficient corresponding to the audio amplitude, the method further includes: adjusting the amplitude adjustment coefficient according to a noise value of an environment in which the terminal device is located; and dividing the amplitude adjustment coefficient Adjusting the coefficient for the preset number of sub-amplitudes includes dividing the adjusted amplitude adjustment coefficient into a preset number of sub-amplitude adjustment coefficients. As shown in FIG. 6, the technical solution provided by this embodiment is as follows:

在一个实施例中，可通过终端设备安装的麦克风采集终端设备当前所处环境的噪音以确定对应的噪声值。在一实施例中，该噪声值越大，对应的对振幅调整系数的调整越大。例如，假设终端设备在安静环境下的噪声值为y，终端设备处于户外或嘈杂环境中时，确定的终端设备所处环境的噪声值为1.5y，则相应的在确定出的振幅调整系数的基础上，将该振幅调整系数乘以1.5作为调整后的振幅调整系数。需要说明的是，还可依据阻抗值、噪声值以及音频振幅的大小共同确定音源的振幅调整系数。In one embodiment, the noise of the environment in which the terminal device is currently located may be collected by a microphone installed in the terminal device to determine a corresponding noise value. In an embodiment, the larger the noise value, the larger the adjustment of the corresponding amplitude adjustment coefficient. For example, if the noise value of the terminal device in a quiet environment is y, and the terminal device is in an outdoor or noisy environment, the noise value of the environment in which the terminal device is determined is 1.5 y, and the corresponding amplitude adjustment coefficient is determined. In addition, the amplitude adjustment coefficient is multiplied by 1.5 as the adjusted amplitude adjustment coefficient. It should be noted that the amplitude adjustment coefficient of the sound source may be jointly determined according to the impedance value, the noise value, and the magnitude of the audio amplitude.
步骤504、将调整后的振幅调整系数划分为预设数目的子振幅调整系数，依据所述子振幅调整系数对所述音频振幅进行调整。Step 504: The adjusted amplitude adjustment coefficient is divided into a preset number of sub-amplitude adjustment coefficients, and the audio amplitude is adjusted according to the sub-amplitude adjustment coefficient.
由上述可知，在对音源的振幅进行调节过程中，考虑了噪声对终端设备音量的影响，将确定的噪声值作为确定振幅调整系数的参量之一，使得调节后的音量大小更加符合用户需求，进一步提高了音量调节效果。It can be seen from the above that in the process of adjusting the amplitude of the sound source, the influence of noise on the volume of the terminal device is considered, and the determined noise value is taken as one of the parameters for determining the amplitude adjustment coefficient, so that the adjusted volume is more in line with the user's demand. Further improved the volume adjustment effect.

调整系数确定模块30，设置为确定和所述音频振幅对应的振幅调整系数，并将所述振幅调整系数划分为预设数目的子振幅调整系数。The adjustment coefficient determining module 30 is configured to determine an amplitude adjustment coefficient corresponding to the audio amplitude, and divide the amplitude adjustment coefficient into a preset number of sub-amplitude adjustment coefficients.
在一个实施例中，为提高音源中低振幅区域的音量，对低振幅的音频振幅分配较大的振幅调整系数，高振幅的音频振幅相应的分配一较小的调整系数。例如，对振幅大小小于-3db且大于-10db音频振幅分配振幅调整系数为1.2，对振幅大小小于-10db且大于-50db的音频振幅分配振幅调整系数为2。此时，在音源播放过程中，如果前一段音频振幅的振幅调整系数为1.2，而过渡到相邻的下一段音频振幅需要振幅调整系数为2的话，进行调整后的音频振幅会存在明显的听感突兀的问题，这是由振幅调整系数跳跃带来的。在一实施例中，所述调整系数确定模块30是设置为通过如下方式将所述振幅调整系数划分为预设数目的子振幅调整系数：检测到不同音频振幅对应的振幅调整系数满足预设条件时，将所述振幅调整系数划分为预设数目的子振幅调整系数。在一实施例中，所述子振幅调整系数为依据所述振幅调整系数线性或非线性划分得到。在一实施例中，该预设条件可以是相邻的音频振幅的振幅调整系数不一致，例如振幅调整系数由前一音频振幅的振幅调整系数1变成后一音频振幅的振幅调整系数2，或振幅调整系数由2变成1.2等。此时，可以在相邻的两个音频振幅对应的两个振幅调整系数之间增加预设数目的子振幅调整系数，在一实施例中，当确定出的相邻音频振幅对应的音频振幅的振幅调整系数分别为1.2和2时，可在1.2到2之间再增加9个等级，即从1.2开始依次递增相同或不同的数值得到：1.28、1.36、1.42、...、1.92。在调节过程中，在振幅调整系数从1.2到2的过渡阶段，可将每n(例如，n大于1小于等于20)帧音频帧对应一个子振幅调整系数，依次对每一帧音频帧的振幅进行调整。例如，振幅调整系数由1.2改变为2时，改变开始时的第1-20帧音频帧对应的子振幅调整系数为1.28，第21-40帧音频帧对应的子振幅调整系数为1.36，依次类推。In one embodiment, to increase the volume of the low amplitude region of the sound source, a large amplitude adjustment factor is assigned to the low amplitude audio amplitude, and a high amplitude audio amplitude is correspondingly assigned a smaller adjustment factor. For example, the amplitude adjustment coefficient of the audio amplitude distribution is less than -3 db and greater than -10 db, and the amplitude adjustment coefficient is 2 for the audio amplitude of amplitudes less than -10 db and greater than -50 db. At this time, during the sound source playing, if the amplitude adjustment coefficient of the previous audio amplitude is 1.2, and the amplitude of the adjustment to the adjacent next audio amplitude requires an amplitude adjustment coefficient of 2, the adjusted audio amplitude will be clearly heard. The problem is abrupt, which is caused by the jump of the amplitude adjustment factor. In an embodiment, the adjustment coefficient determining module 30 is configured to divide the amplitude adjustment coefficient into a preset number of sub-amplitude adjustment coefficients by detecting that an amplitude adjustment coefficient corresponding to different audio amplitudes meets a preset condition. The amplitude adjustment coefficient is divided into a preset number of sub-amplitude adjustment coefficients. In an embodiment, the sub-amplitude adjustment coefficients are obtained by linear or non-linear division of the amplitude adjustment coefficients. In an embodiment, the preset condition may be that the amplitude adjustment coefficients of the adjacent audio amplitudes are inconsistent, for example, the amplitude adjustment coefficient is changed from the amplitude adjustment coefficient 1 of the previous audio amplitude to the amplitude adjustment coefficient 2 of the latter audio amplitude, or The amplitude adjustment coefficient is changed from 2 to 1.2. At this time, a preset number of sub-amplitude adjustment coefficients may be added between two amplitude adjustment coefficients corresponding to two adjacent audio amplitudes. In an embodiment, when determining the audio amplitude corresponding to the adjacent audio amplitude When the amplitude adjustment coefficients are 1.2 and 2, respectively, 9 levels can be added between 1.2 and 2, that is, the same or different values are incremented from 1.2: 1.28, 1.36, 1.42, ..., 1.92. In the adjustment process, in the transition phase of the amplitude adjustment coefficient from 1.2 to 2, each n (for example, n is greater than 1 and less than or equal to 20) frame audio frames may correspond to one sub-amplitude adjustment coefficient, and the amplitude of each frame of the audio frame is sequentially Make adjustments. For example, when the amplitude adjustment coefficient is changed from 1.2 to 2, the sub-amplitude adjustment coefficient corresponding to the 1-20th audio frame at the start of the change is 1.28, and the sub-amplitude adjustment coefficient corresponding to the 21-40th audio frame is 1.36, and so on. .

When the file is played, the audio amplitude is correspondingly increased; or, in the decoding process of the sound source playing, the audio amplitude is obtained by analyzing the obtained digital audio signal, and the amplitude data is multiplied by the corresponding amplitude adjustment coefficient. To change the amplitude, adjust the volume of the source.
本实施例提供的方案实现了在不改变终端设备***原有音量的前提下对音源音量的大小进行了调节，调节过程可以在音源文件未进入缓冲区前，以减少播放负载，也可以是针对缓冲区中的音源内容进行调节以提高调节效率，从而 提高了音量调节效率，降低了终端设备的功耗，且通过使用子振幅调整系数对预设数量的音频帧的音频振幅进行调整，避免了由振幅调整系数的跳跃带来的听感突兀的问题，提高了用户体验。The solution provided in this embodiment implements adjusting the volume of the sound source without changing the original volume of the terminal device system.
