Referring to fig. 2, a method for adjusting media playing volume according to an embodiment of the present invention is applied to a terminal, such as a mobile phone and a tablet computer, and the method includes:
s21: recording the current environmental audio in the playing process of the media player; in the process that a user uses a media player of a terminal, the volume of the current environment is detected by recording the current environment Audio, the recording of the environment Audio can be performed once every preset time, the recording time can be set according to needs, specifically, for example, the recording of the current environment Audio with the preset time of T seconds, the Android system provides three types of recording Audio of MediaRecorder, AudioSource and AudioRecord, and can also directly read the PCM data of the current environment Audio from a read () function of Android Audio Hardware or a tinycap tool provided in a Linux ALSA framework, and the preset time can be very short so as to avoid the delay of ring tone playing.
S22: calculating the current environment volume corresponding to the current environment audio according to the current environment audio; after having recorded the current environment audio frequency at every turn, calculate the current environment volume that current environment audio frequency corresponds promptly to according to the current environment volume of calculating at every turn to the broadcast volume of media player carries out the right-angle adjustment, it is simple and convenient to calculate the current environment volume mode through recording current environment audio frequency, does not need the terminal plus equipment to realize, and the audio frequency of on-the-spot recording has the authenticity more moreover, more is close to the actual conditions of current environment. The environment volume is recorded and calculated in a circulating mode at intervals of preset duration until the media player stops playing, so that the playing volume is timely changed along with the change of the environment volume, and compared with a mode of recording and calculating the environment volume in real time, the energy consumption of the terminal can be saved.
S23: and adjusting the playing volume of the media player according to the current environment volume. The playing volume of the media player is adjusted according to the current environment volume calculated in the step S22, so that the playing volume is automatically adjusted according to the current environment volume in good time, the playing volume of the media player is automatically adapted to the environment where the user is located, for example, in a noisy environment, the playing volume can be increased, in a relatively quiet environment, the playing volume can be decreased, and the like, user operation is not needed, poor experience of the user caused by manual volume adjustment in the prior art is avoided, and humanization of playing volume adjustment is improved.
Alternatively, step S22 may include: acquiring the volume representation intensity corresponding to the current environment audio; selecting a corresponding volume calculation formula according to the volume representation intensity; and calculating the current environment volume corresponding to the current environment audio according to a volume formula. Specifically, when the current environment volume is calculated, the current volume representation intensity is firstly obtained, the volume representation intensity can be selected in advance by a user, different volume representation intensities correspond to different volume calculation formulas, after the volume representation degree is determined, the volume calculation formula under the volume representation degree can be selected to calculate the current environment volume corresponding to the current environment audio, thus, the volume calculation formulas are different, the same current environment audio is fundamentally determined to have different volumes, in the practical application environment, the audio in the environment is generally uncertain, sometimes the volume distribution is uniform, sometimes the volume is greatly different in volume, therefore, for the calculation of the volume of the current environment audio, different environment characteristics can be highlighted by adopting different volume calculation formulas, the diversity of the volume representation degree is realized, and the calculation mode of the current environment volume is enriched, the selectivity of the user for the volume adjustment requirement is also enriched, so that the calculation result can better represent the requirement of the user, and the user experience is improved.
As a specific implementation manner, when the volume characterization intensity is at a first level, determining the volume calculation formula according to the maximum value of all audio sampling points of the current environmental audio and a reference sound pressure; or when the volume characterization intensity is in a second level, determining the volume calculation formula according to the effective values of all audio sampling points of the current environmental audio and the reference sound pressure; or when the volume characterization intensity is in a third level, determining the volume calculation formula according to the average value and the reference amplitude of all audio sampling points of the current environmental audio. Specifically, when the volume characterization intensity is at the first level, the volume calculation formula may be:
wherein L isPFor the current ambient volume, Prms1 is the maximum value of all audio sampling points of the current ambient audio, and Pref is the reference sound pressure; or when the volume characterization intensity is at the second level, the volume calculation formula may be:
wherein L isPFor the current ambient volume, Prms2 is the effective value of all audio samples of the current ambient audio, and Pref is the reference sound pressure; or when the volume characterization intensity is at a third level, the volume calculation formula may be:
wherein L isPFor the current ambient volume, A1Is the average of all audio sampling points of the current ambient audio, A0Is the reference amplitude. Specifically, if the volume is characterized by audio amplitude, the scheme of different volume calculation formulas for different levels of volume characterizing intensity is illustrated as follows:
a first level: in the T seconds of the current environment audio, representing the current environment volume by calculating the maximum value of all sampling points; there are two acquisition modes for the maximum of all the samples:
the first method is as follows: recording current environment audio of T seconds by using a MediaRecorder or an AudioSource, and then using a method getMaxAmplite () of the MediaRecorder or the AudioSource to acquire the maximum value of all sampling points in the T seconds.
The second method comprises the following steps: recording T seconds of audio, storing pcm audio data of the T seconds, and then circularly taking out each sampling point for comparison until the maximum value is calculated. Then, the current environment volume is calculated by adopting the following formula:
wherein L isPFor the current ambient volume, Prms1 is the maximum of all sampled points, and Pref is the reference sound pressure (typically 20 pa, the minimum sound pressure audible to humans). The representation of the current environment volume calculated by the maximum value of the audio sampling point on the environment sound is more massive and strong, but the current environment volume is influenced by the extreme data, for example, a huge sound is generated when a huge object falls off at a certain moment, if the huge sound is collected, the calculation result is very large, and the current environment is possibly quite integrally.
And (3) second grade: in the T second current environment audio, representing the current environment volume by calculating the effective values of all audio sampling points, namely storing the pcm audio data of the recorded T second current environment audio, then circularly taking out each sampling point from the pcm audio data, and calculating the root mean square value of each sampling point by adopting the following formula:
wherein,Xirepresents the value of the ith sample point, N represents the number of samples in T seconds, XrmsRepresents the root mean square of all the sampling points; then, the current environment volume is calculated by adopting the following formula:
wherein L isPFor the current ambient volume, Prms2 is the valid value for all audio samples, and Pref is the reference sound pressure (typically 20 pa, the minimum sound pressure audible to humans). The representation degree of the current environment volume on the current environment audio, which is obtained by calculating the effective values of all the audio sampling points, is smaller than the first level, namely, the influence sensitivity degree of the volume adjustment of the media player on the environment volume is finally smaller than the condition of the first level.
And a third stage: in the T second current environment audio, representing the current environment volume by the average value of all audio sampling points, namely storing the pcm audio data of the recorded T second current environment audio, circularly taking out each sampling point from the pcm audio data, solving the square sum of the sampling points, and dividing the square sum by the sampling times in T seconds; and finally, calculating the current environment volume by adopting the following formula:
wherein L isPFor the current ambient volume, A1Is the average of all audio samples, A0Is a reference amplitude (typically an amplitude corresponding to a sound pressure value of 20 pa, which may be calculated as 1 directly). The current environment volume calculated by the average value of all audio sampling points is stable and is not easily influenced by extreme conditions, but the representation of the environment volume is slower compared with a mode of calculating the maximum value of the audio sampling points.
It should be noted that, for different requirements (degree of the environmental sound characterization by the DB), the level classification of the environmental sound characterization degree may be determined by comprehensively considering the above-mentioned three algorithms for calculating the environmental sound volume, for example, T seconds are divided into n equal parts, the maximum value of the audio sampling point in each equal part is taken, then all the maximum values are summed by the square sum according to the algorithm mentioned in the preset sound sensitivity 2, and then the sum is divided by n, so that the calculated sound volume DB value is between the current environmental sound volumes corresponding to the first level and the second level. Naturally, the method of calculating the current environment volume according to the present invention is not limited to the above-described combination of calculation, and any calculation method that can implement the technical solution of the present embodiment is applicable to the present invention.
Alternatively, step S23 may include: acquiring a playing volume grade corresponding to the current environment volume according to the corresponding relation between the environment volume and the media playing volume; and adjusting the playing volume of the media player to the media playing volume corresponding to the playing volume level. Specifically, a table of a corresponding relationship between the environment volume and the media playing volume may be established in advance according to human hearing habits, the playing volume level may be labeled in the relationship table, after the current environment volume is obtained through calculation, the playing volume level corresponding to the current environment volume is obtained from the relationship table, and then the playing volume of the media player is adjusted by the media playing volume corresponding to the playing volume level, for example, the table of the corresponding relationship between the environment volume and the media playing volume may be established with reference to the following manner:
the Android system defines the level of the playing volume as 0-15 levels (0: the minimum volume is equivalent to silence, and 15: the maximum sound) and divides DB into 15 levels according to the decibel entry on Wikipedia, the levels are respectively corresponding to the prompt tone levels of 1-15 of the Android system, and a table of the corresponding relation between the environment volume and the media playing volume can be obtained, and the table is shown as the following table:
| DB | grade of the warning tone |
| 0-10 extremely quiet, hardly felt | 1 |
| 10-20 | 2 |
| 20-30 quiet, soft talk | 3 |
| 30-35 | 4 |
| 35-40 | 5 |
| 40-45 general, ordinary indoor talk | 6 |
| 45-50 | 7 |
| 50-55 | 8 |
| 55-60 | 9 |
| 60-65 noisy | 10 |
| 65-70 | 11 |
| 70-80 are noisy and nerve cells may be affected | 12 |
| 80-90 | 13 |
| 90-100 hearing impairment | 14 |
| Over 100 | 15 |
Of course, the volume level allocation shown in the above table can be reasonably adjusted according to specific situations, for example, the sound size of each level of the volume level played by the mobile phone, the degree of change between levels, and the like can be adjusted. When the current environment volume is calculated, the corresponding volume level (namely the playing volume level) can be matched from the table, and then the playing volume of the media player is adjusted to the volume level, so that the media playing volume is not only related to the volume representation strength selected by the user and the current environment audio, but also influenced by the volume use habit of the user, and the media playing volume is more in line with the personal requirements of the user and is more humanized.
Optionally, before step S23, the method may further include: and when the media player is started, controlling the media player to output the playing volume at the preset volume. Specifically, when a user just starts the media player, the playing volume is output at a preset volume, where the preset volume can be very small and can hardly be heard by the user, so as to avoid disturbing others due to too large playing volume in a quiet environment, and meanwhile, it can be ensured that the playing volume is not delayed before the playing volume of the media player is adjusted according to the current environment volume.
In the method for adjusting the volume of the media playing provided in this embodiment, in the process that a user uses a media player of a terminal, the volume of the current environment is detected by recording the current environment audio, where the recording of the environment audio can be performed once every preset time duration, the recording time duration can be set as required, after the recording is completed every time, the current environment volume corresponding to the recorded current environment audio is calculated, and finally the playing volume of the media player is adjusted according to the calculated current environment volume, so that the playing volume is automatically adjusted according to the current environment volume at proper time without user operation, bad experience brought to the user by manually adjusting the volume in the prior art is avoided, and the humanization of the adjustment of the playing volume is improved.
