The terms "first," "second," and the like in the description and in the claims, or in the drawings, are used for distinguishing between different objects and not necessarily for describing a particular sequential order.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.
In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Referring to fig. 1, a flow chart of a volume adaptive adjusting method according to an embodiment of the present invention is shown, where the volume adaptive adjusting method includes the following steps:
step 101: the method comprises the steps of obtaining a preset system standard volume N for playing audio, and obtaining a current playing volume X of the currently played audio.
Specifically, the standard volume of the system is a common volume when a user generally listens to a song or plays content such as video with audio by using a player. The current playing volume is the current system volume of the terminal device used by the user, and the terminal device may be various electronic devices supporting listening to Audio or watching video, including but not limited to a smart phone, a tablet computer, an MP3 player (Moving Picture Experts Group Audio Layer III, motion video Experts compressed standard Audio Layer 3), an MP4 player (Moving Picture Experts Group Audio Layer IV, motion video Experts compressed standard Audio Layer 4), a laptop portable computer, a desktop computer, and the like.
In some embodiments of the present application, when the system standard volume is preset, the optimal volume when the user plays audio may be obtained by querying a historical play volume used when the user plays different audio in a historical time period, and the optimal volume is used as the system standard volume when the audio is played.
For example, if the volume used by the user to listen to the audio is 50 in one month, then 50 may be used as the system standard volume N for audio playing, and of course, if the volumes used by the user to play the audio in a history time period are all different, the average value of the history playing volume in the history time period may be taken as the system standard volume for the user to play the audio.
When it is detected that there is no record for playing audio before the user, a system standard volume can be directly obtained from the server and used as the system standard volume when the current terminal plays audio.
Generally, the most suitable volume range for listening to audio is between 45 db and 65 db, and thus the system standard volume can be set between 45 db and 65 db. Of course, the standard volume of the system can be adjusted adaptively according to individual differences of different users.
Step 102: and before switching the currently played audio to the next audio, confirming the next audio to be played and acquiring the sound source volume Y of the next audio.
In the embodiment of the present application, since the audio file carries an initial volume, that is, a sound source volume, and the sound source volume is affected by different styles of music, music can be played at different volumes on the premise that the current playing volume is not changed. For example, when the current audio is a music of the lyric type, the music of the lyric type can be played with a smaller volume because the volume of the sound source carried in the music file is smaller; if the current audio is music of a rock type, the music of the rock type can be played at a higher volume because the volume of the sound source carried in the music file is higher. If the lyric type music and the rock type music are two adjacent audio frequencies, the user needs to turn the volume down (or up) and then turn the volume up (or down), so that the user cannot enjoy the music well, and inconvenience is brought to the user.
Step 103: and after a first adjusting coefficient A is calculated according to a first formula A ═ N/Y, the volume Z to be played of the next audio is calculated according to a second formula Z ═ A ×.X.
Specifically, since the actual playing volume of the audio is affected by the current playing volume X and the sound source volume Y, after the system standard volume N is obtained, the system standard volume N is first divided by the sound source volume Y to obtain a first adjustment coefficient a, the current playing volume X is multiplied by the first adjustment coefficient a to obtain the volume Z to be played, and the value of the volume Z is used as the volume when the next audio is played.
For example, the system standard volume N is set to 35 db, the sound source volume Y of the next audio is 50 db, and when the current playing volume X is 50 db, the first adjustment coefficient a is calculated to be 0.7, and the playing volume Z of the next audio to be played is 35 db.
Step 104: and after receiving an audio switching instruction for playing the next audio, responding to the audio switching instruction and playing the next audio at the volume to be played.
According to the method and the device, when the user uses the audio playing device to play music and outputs the music through the output device, the volume of the music with different styles is adjusted through the self-adaptive volume adjusting method, and the situation that the user repeatedly adjusts the current playing volume when listening to the music is avoided.
In this embodiment, a preset system standard volume N for playing an audio is obtained, a current playing volume X of a terminal is obtained, a sound source volume Y of a next audio is extracted from a next audio file to be played, a first adjustment coefficient a is obtained through calculation according to a first formula a ═ N/Y, and then a volume Z to be played of the next audio is calculated according to a second formula Z ═ a ×; and finally, the next audio to be played can be played through the adaptive volume Z to be played, so that the playing volume of the music with different styles can be adaptively adjusted, the playing volume of the music with different styles is suitable, and good audio using experience is provided for users.
In some embodiments of the present application, in the step 101, the step of obtaining a preset system standard volume N for playing audio includes:
step 1011: and querying historical playing volume set by a user when different audios are played in a historical time period, and taking the average value of the historical playing volume as the value of N.
In this embodiment, the system standard volume N may be set in advance, and during the setting, the historical playing volume used by all the audios played by the user in a historical time period may be queried, and the average value of the historical playing volumes of different audios played in the time period is used as the value of the system standard volume N.
In some embodiments of the present application, in the step 101, before the step of obtaining the current playing volume X of the currently played audio, the volume adaptive adjusting method further includes:
step 1012; comparing the value of X with a first preset value and a second preset value; wherein the second preset value is greater than the first preset value.
Step 1013: if the value of X is smaller than the first preset value, adjusting the value of X to the first preset value; and if the value of X is larger than the second preset value, adjusting the value of X to be the second preset value.
In this embodiment, for the current playing volume X, in order to ensure that the current playing volume X is within a range suitable for playing audio and avoid adverse effects of playing audio due to too small or too large of the current playing volume X, volume intervals with boundaries respectively being a first preset value and a second preset value are preset as limitations on the current playing volume X, where the second preset value is greater than the first preset value.
The value of the current playing volume X cannot be smaller than a first preset value, and when the value of X is smaller than the first preset value, the first preset value is used as the value of the current playing volume X; and the value of the current playing volume X cannot be larger than a second preset value, and when the value of the X is larger than the second preset value, the second preset value is used as the value of the current playing volume X.
The first preset value can be set to 20 db, and the second preset value can be set to 70 db. When the sound volume is less than 20 decibels, the current playing sound volume X is too small, so that the user cannot hear clearly; above 70 db, the user may feel too loud, causing user discomfort. Of course, due to individual differences of users, adaptive adjustment can be performed for the first preset value and the second preset value.
In this embodiment of the present application, the step 103 further includes:
Step 1031: and detecting whether the value of A is within a preset specific interval range, and if so, replacing the second formula with a third formula Z-a-X.
Step 1032: and correcting the A according to a preset rule to obtain a second adjusting coefficient a, and further calculating the volume Z to be played of the next audio according to the third formula.
Further, the preset rule specifically includes: when the value of A is between 0.4 and 0.6, correcting the A according to a first regulation formula a-A x 1.5 to obtain a second regulation coefficient a;
when the value of A is between 0.6 and 0.8, correcting the A according to a second regulation formula a-A x 1.2 to obtain a second regulation coefficient a;
when the value of A is between 1.2 and 1.4, correcting the A according to a third regulation formula a-A-0.85 to obtain a second regulation coefficient a;
and when the value of A is between 1.4 and 1.6, correcting the A according to a fourth regulation formula a-A0.65 to obtain a second regulation coefficient a.
Specifically, because the system standard volume N is a fixed value, and the sound source volume Y of the next audio to be played is also a determined value when the audio is determined, the current playing volume X plays an important role in the volume Z of the next audio to be played. Therefore, under the condition of different currently played volume X, the obtained Z value may not be suitable for the volume of the next audio to be played, so that the obtained Z value may be further corrected to ensure that the Z value can be suitable for the next audio to be played.
When the set first regulation formula, the second regulation formula, the third regulation formula and the fourth regulation formula are applied, the interval that the value of A corresponding to the first regulation formula is satisfied when the first regulation formula is applied is 0.4-0.6, namely more than or equal to 0.4 and less than 0.6, and other intervals are similar and are not repeated.
When the system standard volume N is set to 35 db, the sound source volume Y of the next audio to be played is 50 db, and the current playing volume X is 50 db, the first adjustment coefficient a is calculated to be 0.7, and Z is 35 db for example. At this time, the first adjustment coefficient is between 0.6 and 0.8, so that the first adjustment coefficient A is multiplied by 1.2 to obtain a corrected second adjustment coefficient a of 0.84, and then the value a is multiplied by the value 50 of the current playing volume X to obtain Z of 42 decibels, namely 42 decibels are taken as the volume to be played of the music to be played.
In some optional implementations of this embodiment, after the step 1032, the method for adaptively adjusting a volume further includes the step of:
detecting whether the value of Z is 0.6-1.4 times of the value of N, if not, updating the value of Z according to the following rules:
if the value of Z is more than or equal to 1.4 times of the value of N, taking 1.4 times of the value of N as the value of Z;
And if the value of Z is less than 0.6 times the value of N, taking 0.6 times the value of N as the value of Z.
Specifically, for the volume Z to be played of the next audio to be played after the correction, a detection step may be performed to ensure that Z can play the next audio as the most suitable volume.
In combination with the above example, when the volume Z to be played of the next audio to be played is 42 db, the system standard volume N is 50 db, and the volume to be played is 0.84 times the system standard volume and is between 0.6 and 1.4 times the system standard volume, so that 42 db is determined as the volume to be played. If the obtained volume to be played is 28 db and the system standard volume is 50 db, then 0.6 db, that is, 30 db, of the system standard volume is required to be used as the volume to be played of the next audio to be played. If the obtained volume to be played is 75 db and the system standard volume is 50 db, 1.4 times, i.e. 70 db, of the system standard volume is required to be used as the volume to be played of the next audio to be played.
Further, the step 103 further includes: detecting the value of A, and if the value of A is less than 0.4, taking 0.4 as the value of A; and if the value of A is more than 1.6, taking 1.6 as the value of A.
When the first adjustment coefficient a exceeds 1.6, at this time, the system standard volume N exceeds the sound source volume Y of the next audio to be played too much, and it cannot be ensured that the adjusted volume can be adapted by the user, so that 1.6 can be used as the first adjustment coefficient a, and it is ensured that the corrected volume can be adapted by the user.
For example, when the system standard volume N is 45 db, the sound source volume Y of the next audio to be played is 20 db, and the current playing volume X is 20 db, the first adjustment coefficient a is 2.25 and exceeds 1.6, and if the first adjustment coefficient is directly set to 2.25, the volume Z to be played of the next audio to be played is 45 db, which may cause a user adapted to a low volume to suddenly hear a high volume, and thus the user may be frightened. However, if 1.6 is used as the first adjustment coefficient, the volume Z to be played of the next audio to be played is 32 db, which can effectively prevent the user from being surprised by suddenly hearing the audio with high volume.
In a specific implementation manner of this embodiment, a historical playing volume set when a user plays different audios within a certain period is obtained, an average value of the historical playing volume within the period is taken as a system standard volume N, a current playing volume X is obtained at the same time, a range of the current playing volume X is detected, the historical playing volume is ensured to be between a first preset value and a second preset value, a sound source volume Y of a next audio to be played is extracted at the same time, then a first adjustment coefficient a is obtained by calculating a ratio of the system standard volume N to the sound source volume Y, the first adjustment coefficient a is modified by detecting an interval range of the first adjustment coefficient a to obtain a second adjustment coefficient a, the second adjustment coefficient a is multiplied by the current playing volume X to obtain a volume Z to be played, and finally a next audio is played at the playing volume Z, so that the current playing volume X and the first adjustment coefficient a can be modified, the final volume Z to be played can be ensured to be the most suitable volume of the next audio to be played to play the audio, and the requirement of the user for enjoying the audio is met.
Referring to fig. 2, as an implementation of the method shown in fig. 1, an embodiment of a volume adaptive adjusting apparatus is provided, where the embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 1, and the apparatus may be specifically applied to various electronic devices, and the volume adaptive adjusting apparatus 300 of the embodiment includes: a volume acquiring module 301, an audio confirming module 302, a volume calculating module 303 and an audio playing module 304.

Specifically, after the volume Z to be played is calculated by the volume calculation module 303, the next audio can be played at the volume Z to be played through the audio playing module 304, and the volume Z to be played at this time can be well adapted to the audio of different music winds, so that the user can enjoy music well.

Specifically, since the current playing volume is not necessarily within a reasonable range, before the volume calculation module 303 performs calculation, the volume adjustment sub-module 3011 may detect the current playing volume X, and determine whether the current playing volume X is between a first preset value and a second preset value, where the first preset value and the second preset value may be adjusted by the user. If the value of the current playing volume X is smaller than a first preset value, taking the first preset value as the current playing volume X; and if the value of the current playing volume X is larger than the second preset value, taking the second preset value as the current playing volume X, so as to ensure that the current playing volume X can be in a reasonable range, and the volume Z to be played is calculated to be the volume in the reasonable range.
