Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In some embodiments of the present invention, referring to fig. 1, there is provided an audio playing method, including:
step 101, collecting a sound signal played by a terminal through a loudspeaker, and acquiring the loudness L of the sound signal and the media volume level V of the terminal when the sound signal is played.
The real-time monitoring of the sound signal played by the terminal is realized by acquiring the sound signal played by the terminal through the loudspeaker and acquiring the loudness L of the sound signal and the corresponding media volume level V, so that the sound signal played by the terminal can be found and adjusted in time when the loudness changes suddenly.
The sound signals played by the terminal through the loudspeaker can be collected through the microphone mic. The loudness L of the sound signal played by the terminal through the speaker may be obtained by obtaining the average loudness of the sound signal played by the terminal through the speaker in the δ T every time the preset time period δ T passes, or by obtaining the loudness of the sound signal played by the terminal through the speaker at the current time every time the preset time period δ T passes.
The terminal generally has 32 levels of media volume levels (but not limited thereto), and the media volume level is higher from 1 to 32 levels (+1 represents increasing by one level and-1 represents decreasing by one level).
Step 102, if the obtained second loudness L2 is larger than the first loudness L1, determining whether the larger amplitude of the second loudness L2 meets a first preset condition; wherein the second loudness L2 is the loudness acquired next time after the first loudness L1 is acquired.
Here, if the second loudness L2 acquired later becomes larger than the first loudness L1 acquired earlier, it is determined whether the larger amplitude satisfies a first preset condition, where the first preset condition is a criterion for determining the larger amplitude of the loudness, and if the first preset condition is satisfied, the larger amplitude of the loudness becomes, that is, the sound has a large sudden change, the loudness needs to be reduced by adjusting, and if the first preset condition is not satisfied, the larger amplitude of the loudness is within a range accepted by the user, and the loudness does not need to be reduced.
The first preset condition may be set according to a requirement, for example, the first preset condition is that the second loudness L2 is greater than the first loudness L1 by a preset multiple, or the second loudness L2 minus the first loudness L1 is greater than a preset threshold, and the like.
Here, if the increased amplitude of the second loudness L2 satisfies the first preset condition, which indicates that the sound has a large sudden change, the media volume level V and/or the amplitude of the source audio signal are adjusted according to the first media volume level V1 corresponding to the first loudness L1 obtained before and the second media volume level V2 corresponding to the second loudness L2 obtained after, so that the loudness of the sound after follows the loudness before, and the sudden change of the sound is avoided.
The loudness of the sound signal played by the terminal is directly related to the media volume level and the amplitude of the source audio signal, and the loudness of the sound signal played by the terminal is larger when the media volume level is higher or the amplitude of the source audio signal is larger.
The audio playing method provided by the embodiment of the invention can automatically adjust the media volume level and/or the amplitude of the source audio signal according to the loudness change, ensures that the sound does not have great mutation when the video is played, improves the hearing and improves the user experience. The problem of play video in-process can appear among the prior art and play the condition that the sound loudness of content is very different, can cause the ear to not adapt to, influence user experience is solved.
Optionally, in step 101, acquiring a sound signal played by the terminal through a speaker, and acquiring a loudness of the sound signal, includes:
step 1011, collecting a sound signal played by the terminal through a loudspeaker, and converting the sound signal into an audio signal.
Here, the sound signal played by the terminal through the speaker is firstly collected, and then the sound signal is converted into an audio signal, which is convenient for further processing.
Here, the audio signal refers to an electrical signal propagated by an electric current. The acoustic signal is a vibration signal that propagates through a medium such as air. And audio signals in the terminal are played through a loudspeaker to obtain sound signals, and the sound signals are acquired and then need to be converted into audio signals for further processing.
The microphone mic can be used for collecting the sound signals played by the terminal through the loudspeaker, and then the sound signals are converted into audio signals.
Step 1012, determining the loudness of the sound signal according to the audio signal and the corresponding relationship between the preset audio signal and the loudness.
Here, according to the audio signal converted from the sound signal and the preset correspondence between the audio signal and the loudness, the loudness corresponding to the audio signal, that is, the loudness L of the sound signal, can be accurately determined.
Wherein the correspondence between the audio signal and the loudness may be obtained in advance through a large amount of experimental data. For example, the proportionality coefficient k between the audio signal and the loudness L (unit: dB) can be obtained in advance through experimental data, and then the corresponding loudness of the audio signal can be determined through the following formula: l ═ k × E, where E (unit: mV) is the magnitude of the electrical signal corresponding to the audio signal.
Further, in order to eliminate the influence of the ambient noise on the loudness of the collected sound signal, after the sound signal played by the collection terminal through the speaker, the method may further include:
step 1013, converting the sound signal into an audio signal.
Here, after the sound signal that the collection terminal passed through the speaker broadcast, convert the sound signal into audio signal, be convenient for further processing.
Step 1014, comparing the audio signal with a source audio signal corresponding to the sound signal, and denoising the audio signal according to a comparison result.
Here, a noise elimination algorithm similar to a hands-free voice call may be adopted to compare the audio signal converted from the sound signal with the source audio signal corresponding to the sound signal, and then perform denoising processing on the converted audio signal according to the comparison result to eliminate the influence of the environmental noise on the loudness of the collected sound signal.
Specifically, the denoising processing of the audio signal according to the comparison result may include: if the comparison result shows that the frequency spectrum of the audio signal is greatly different from the frequency spectrum of the source audio signal, the audio signal is judged to be noise, and the signal judged to be noise is attenuated, so that the influence of the environmental noise on the loudness of the collected sound signal is eliminated.
Optionally, in the step 102, judging whether the amplitude of the second loudness increase meets a first preset condition includes:
judging whether the second loudness L2 is greater than the loudness of the first loudness L1 increased by a preset multiple; if the loudness is greater than the first preset condition, determining that the increased amplitude of the second loudness L2 meets the first preset condition, otherwise, determining that the increased amplitude of the second loudness L2 does not meet the first preset condition.
Here, the first preset condition is that the second loudness L2 is greater than the loudness of the first loudness L1 increased by a preset multiple (e.g., 1.2 times). If the loudness of L2 is greater than that of L1 after the increase by a predetermined multiple (e.g., L2 > 1.2L1), that is, the first predetermined condition is satisfied, indicating that the sound has a large abrupt change, the loudness needs to be decreased by adjustment. If the L2 is not more than the loudness of the L1 increased by the preset times (such as L2 is less than or equal to 1.2L1), the first preset condition is not met, which indicates that the sound has no large abrupt change and does not need to reduce the loudness.
Of course, the above-mentioned 1.2 times are exemplified, but not limited thereto, and the preset times can be specifically adjusted according to actual situations.
Optionally, referring to fig. 2, in the step 103, adjusting preset parameters affecting the loudness of the sound signal according to the first media volume level V1 corresponding to the first loudness L1 and the second media volume level V2 corresponding to the second loudness L2 includes:
Here, by comparing V1 with V2, V2 can be adjusted according to the comparison result so that the loudness of the sound after the comparison is closer to the loudness before the comparison, thereby avoiding sudden changes in the sound.
In step 1032, if the second media volume level V2 is greater than the first media volume level V1, the second media volume level V2 is decreased to the first media volume level V1.
Here, if V2 > V1, the media volume level is lowered to V1, so that the loudness of the sound signal played by the terminal is reduced and abrupt changes in sound are avoided.
Optionally, with continuing to refer to fig. 2, after step 1031, the method further includes:
in step 1033, if the second media volume level V2 is less than or equal to the first media volume level V1, it is determined whether the second media volume level V2 is the minimum volume level.
Here, if V2 ≦ V1, it is determined whether V2 is the minimum volume level to make further adjustment according to the determination result.
At step 1034, if the second media volume level V2 is not the minimum volume level, the second media volume level V2 is decreased by a first predetermined number of levels.
Here, if V2 is not the minimum volume level, V2 is decreased by a first preset number (e.g., 1) of levels, so as to decrease the loudness of the sound signal played by the terminal and avoid abrupt changes in sound.
In step 1035, if the second media volume level V2 is the minimum volume level, the amplitude of the source audio signal corresponding to the sound signal is decreased.
Here, if V2 is already at the minimum volume level, the amplitude of the source audio signal is directly decreased, so as to reduce the loudness of the sound signal played by the terminal and avoid abrupt change of sound.
It has been mentioned above that the loudness of the sound signal played by the terminal is directly related to the media volume level and the amplitude of the source audio signal, and the loudness of the sound signal played by the terminal is greater when the media volume level is higher or the amplitude of the source audio signal is greater.
At the moment, the loudness of the suddenly increased sound signal can be reduced by adjusting the media volume level or the amplitude of the source audio signal, so that sudden change of sound is avoided, and the user experience is ensured.
Optionally, after the step 101, the method further includes:
judging whether the third media volume level V3 corresponding to the acquired third loudness L3 is increased or decreased by a second preset number of levels compared with the preset media volume level Vr; if so, the third media volume level V3 is adjusted to the preset media volume level Vr.
Here, after the loudness of the sound signal played by the terminal and the corresponding media volume level are acquired each time, the acquired third media volume level V3 is compared with the preset media volume level Vr, and if the V3 is increased or decreased by a second preset number (e.g., 2) levels compared with Vr, the V3 is adjusted to Vr, so that the media volume level of the terminal is controlled to change within the second preset number (e.g., 2) levels above and below Vr, abrupt change of sound is further avoided, and user experience is ensured.
Wherein the preset media volume level Vr may be a media volume level that a user manually adjusts in advance.
Assuming that the second predetermined number is 2, if V3-Vr is greater than or equal to 2, or Vr-V3 is greater than or equal to 2, V3 is adjusted to the level of Vr.
According to the audio playing method, the media volume level and/or the amplitude of the source audio signal are/is automatically adjusted according to the loudness change, so that when the video is played and the advertisement is inserted, the sound does not have great mutation, the hearing sense is improved, and the user experience is improved.
The following illustrates a specific application example of the audio playing method according to the embodiment of the present invention.
It is assumed that the audio playing method of the embodiment of the present invention is applied to a scene in which a video player is used to play a video at a terminal, and the terminal includes 32 media volume levels. When the terminal plays a video, the video player firstly obtains a source audio signal of the video, and transmits the source audio signal to the audio processing module, the audio processing module performs fade-in and fade-out, amplitude adjustment, other audio algorithm processing and the like on the source audio signal, and transmits the processed audio signal to the audio power amplifier PA module. The audio power amplifier PA module is used for amplifying the audio signals, increasing the driving capability and driving the loudspeaker SPK to vibrate and sound. Loudspeaker SPK drives the air sound production through the vibration, plays sound signal.
Because the audio processing module and the audio power amplifier PA module can perform amplitude adjustment, amplification and other processing on the source audio signal according to the media volume level, the media volume level has a direct relation with the loudness of the sound signal emitted by the final loudspeaker SPK. And the amplitude of the source audio signal also directly affects the loudness of the sound signal emitted by the final loudspeaker SPK.
The audio playing method of the embodiment of the invention firstly collects the sound signal played by the loudspeaker SPK through the microphone mic, converts the sound signal into the audio signal E, and then according to the proportion coefficient k between the audio signal and the loudness obtained in advance, the audio playing method is realized through the following formula: and determining the loudness corresponding to the audio signal, namely the loudness L of the sound signal, and determining the media volume level V of the terminal when the sound signal is played. Judging whether the third media volume level V3 corresponding to the acquired third loudness L3 is increased or decreased by 2 levels compared with the preset media volume level Vr; if so, V3 is adjusted to Vr, thereby controlling the media volume level of the terminal to vary within 2 levels up and down Vr. If the later acquired second loudness L2 is greater than the earlier acquired first loudness L1, and L2 > 1.2L1, then compare the first media volume level V1 corresponding to L1 with the second media volume level V2 corresponding to L2; if V2 > V1, then the media volume level is lowered to V1; if V2 is less than or equal to V1, judging whether V2 is the minimum volume level; if V2 is not the minimum volume level, then V2 is lowered by 1 level; if V2 is already at the minimum volume level, the amplitude of the source audio signal is directly reduced.
Therefore, when the amplitude of the loudness increase is large, the processing result of the audio processing module and the audio power amplifier PA module on the audio signal can be influenced by adjusting the media volume level or reducing the amplitude of the source audio signal, so that the loudness of the audio signal is reduced, the sudden change of sound is avoided, and the user experience is ensured.
In summary, the audio playing method of the embodiment of the present invention can automatically adjust the media volume level and/or the amplitude of the source audio signal according to the loudness variation, thereby ensuring that the sound does not have a great sudden change when playing the video, improving the listening experience, and improving the user experience. The problem of play video in-process can appear among the prior art and play the condition that the sound loudness of content is very different, can cause the ear to not adapt to, influence user experience is solved.
