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.
Referring to fig. 1, fig. 1 is a flowchart of an audio playing method according to an embodiment of the present invention, as shown in fig. 1, including the following steps:
The audio to be played may include at least 2 notes, each note corresponds to a frequency point and loudness, and it should be noted that the frequency point and loudness corresponding to each note may be set at the beginning of the activation of the mobile terminal.
And step 102, determining whether a target frequency point consistent with a pre-stored frequency point exists in the frequency points corresponding to each note.
Whether a target frequency point exists in the frequency points corresponding to each note of the audio to be played can be determined. For example: and if the audio to be played comprises a first note and a second note, the first note corresponds to the first frequency point, and the second note corresponds to the second frequency point, judging whether the target frequency point exists in the first frequency point and the second frequency point. The target frequency point is consistent with the pre-stored frequency point, for example: if the pre-stored frequency point is the first frequency point or the second frequency point, it can be determined that a target frequency point exists in the frequency points corresponding to each note of the audio to be played, otherwise, the target frequency point does not exist. It should be noted that the frequency points and the frequencies are in a one-to-one correspondence relationship.
And 103, if the target frequency point exists, acquiring the target loudness corresponding to the target frequency point according to the corresponding relation between the pre-stored frequency point and the loudness.
When the mobile terminal is cracked and the sound production effect of the mobile terminal is poor, namely when noise or sound breaking exists in sound produced by the mobile terminal, the loudness corresponding to the pre-stored frequency point is a first loudness; when the loudness corresponding to the pre-stored frequency point is set as the target loudness, the occurrence effect of the mobile terminal can be improved. That is, the possibility of the sound emitted from the mobile terminal being a noise or a break sound is reduced.
And when the target frequency point exists, the loudness corresponding to the target frequency point is also the target loudness.
And step 104, controlling the musical notes corresponding to the target frequency points to be played at the target loudness.
When the mobile terminal plays the musical notes corresponding to the target frequency points in the audio to be played, the musical notes corresponding to the target frequency points can be controlled to be played at the target loudness.
The Mobile terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
In the embodiment of the invention, the frequency point corresponding to each note of the audio to be played is identified; determining whether a target frequency point consistent with a prestored frequency point exists in the frequency points corresponding to each note; if the target frequency point exists, acquiring the target loudness corresponding to the target frequency point according to the corresponding relation between the prestored frequency point and the loudness; and controlling the musical notes corresponding to the target frequency points to be played at the target loudness. Through the steps, the loudness of the mobile terminal when playing the musical notes corresponding to the target frequency points is controlled to be the target loudness, the possibility that the sound emitted by the mobile terminal has noise or sound breaking is reduced, and therefore the sound production effect of the mobile terminal is improved.
Referring to fig. 2, fig. 2 is a flowchart of another audio playing method according to an embodiment of the present invention. The main difference between this embodiment and the previous embodiment is that the mobile terminal can compare the generated target frequency response curve with the pre-stored frequency response curve, and if there is a pre-stored frequency point, the loudness corresponding to the pre-stored frequency point is set as the target loudness. As shown in fig. 2, the method comprises the following steps:
The content of the pre-stored audio may be a piece of music or a piece of poetry recitation, and the specific content is not limited herein.
Optionally, before step 201, the following steps may be further included:
acquiring a second audio signal, and generating a second frequency response curve according to the second audio signal, wherein the second audio signal is an audio signal acquired by a microphone of the mobile terminal when the mobile terminal does not play a pre-stored audio;
step 201 may include:
acquiring the first audio signal, and generating a first frequency response curve according to the first audio signal;
and obtaining a target frequency response curve according to the first frequency response curve and the second frequency response curve, wherein the ordinate of the target frequency response curve is the difference value between the amplitude corresponding to each frequency point on the first frequency response curve and the amplitude corresponding to the frequency point on the second frequency response curve, and the abscissa of the target frequency response curve is the frequency point corresponding to the difference value.
The second audio signal is an audio signal acquired by a microphone of the mobile terminal when the mobile terminal does not play a pre-stored audio. For example: and when the mobile terminal is in a noisy environment, the acquired second audio signal is the acquired noise signal in the environment.
The first audio signal is an audio signal acquired by a microphone of the mobile terminal when the mobile terminal plays a pre-stored audio. It is understood that the acquired first audio signal includes a signal of pre-stored audio played by the mobile terminal and a noise signal in the environment.
In this embodiment, the target frequency response curve is obtained by obtaining the second audio signal and the first audio signal and according to the first frequency response curve and the second frequency response curve. The influence of the noise signal in the environment where the mobile terminal is located on the collected audio signal can be reduced, and therefore the error of the judgment result caused by the noise signal can be reduced.
The frequency points corresponding to each note in the first audio signal have corresponding amplitudes on the target frequency response curve and the pre-stored frequency response curve, the difference value of the corresponding amplitudes of the frequency points corresponding to each note on the target frequency response curve and the pre-stored frequency response curve can be calculated, and whether the difference value is larger than a preset difference value or not is determined. It should be noted that the preset difference may be gradually adjusted in the process of using the mobile terminal, or may be set at the beginning of starting the mobile terminal, and the specific value of the preset difference is not specifically limited herein.
And 203, determining the loudness corresponding to the pre-stored frequency points as the target loudness.
The display screen of the mobile terminal is provided with a crack, and when the sound production effect of the mobile terminal is poor, namely when noise or sound breaking exists in sound produced by the mobile terminal, the loudness corresponding to the pre-stored frequency point is the first loudness. The loudness corresponding to the pre-stored frequency point can be determined as the target loudness from the first loudness. It should be noted that the target loudness is less than the first loudness. In addition, the specific value of the target loudness may be not determined, and the value obtained by subtracting the fixed value from the first loudness is the target loudness; of course, the specific value of the target loudness may be predetermined, and then the first loudness is directly determined as the target loudness.
In this embodiment, the mobile terminal may compare a target frequency response curve generated according to the acquisition of the first audio signal with a pre-stored frequency response curve, and if there is a pre-stored frequency point, determine the loudness corresponding to the pre-stored frequency point as the target loudness. Through the steps, the target loudness can be determined by controlling the loudness corresponding to the pre-stored frequency points, so that the possibility of the situation that noise or sound breaking exists in the sound emitted by the mobile terminal is reduced, and the sound production effect of the mobile terminal is improved.
Optionally, step 203 may include:
if the amplitude value of the prestored frequency point corresponding to the target frequency response curve is larger than the amplitude value of the prestored frequency response curve, determining whether a first amplitude value difference value is larger than a preset difference value, wherein the first amplitude value difference value is the amplitude value of the prestored frequency point corresponding to the target frequency response curve, and subtracting the amplitude value corresponding to the prestored frequency response curve;
if the first amplitude difference value is larger than the preset difference value, determining the loudness corresponding to the prestored frequency point as the target loudness by subtracting the first amplitude difference value;
or, if the amplitude of the pre-stored frequency point corresponding to the pre-stored frequency response curve is greater than the amplitude of the pre-stored frequency response curve corresponding to the target frequency response curve, determining whether a second amplitude difference value is greater than the preset difference value, wherein the second amplitude difference value is the amplitude of the pre-stored frequency point corresponding to the pre-stored frequency response curve, and subtracting the amplitude corresponding to the target frequency response curve;
and if the second amplitude difference is larger than the preset difference, determining the loudness corresponding to the pre-stored frequency point as the target loudness by adding the second amplitude difference.
In the embodiment of the invention, the processing mode is determined by determining the amplitude of the prestored frequency point corresponding to the prestored frequency response curve and the specific size of the amplitude corresponding to the target frequency response curve according to the specific size. Therefore, the judgment result is more accurate, and the processing mode is more reasonable.
Optionally, after step 203, the method may further include the steps of:
determining whether the frequency of determining the loudness corresponding to the prestored frequency point as the target loudness is greater than a preset frequency;
and if the loudness corresponding to the pre-stored frequency point is determined that the frequency of the target loudness is less than or equal to the preset frequency, returning to execute the step 201.
The specific numerical value of the preset number is not limited, for example: the preset number of times may be 3 times, 5 times, etc. When the number of times of determining the loudness corresponding to the pre-stored frequency point as the target loudness is greater than the preset number of times, a prompt message for indicating that the sound effect of the mobile terminal is improved and the expected effect is not achieved can be displayed on the mobile terminal.
In the embodiment of the invention, when the frequency of determining the loudness corresponding to the pre-stored frequency point as the target loudness is less than or equal to the preset frequency, the step of obtaining the first audio signal is returned to be executed.
And step 204, identifying a frequency point corresponding to each note of the audio to be played.
The audio to be played may include at least 2 notes, each note corresponds to a frequency point and loudness, and it should be noted that the frequency point and loudness corresponding to each note may be set at the beginning of the activation of the mobile terminal.
And step 205, determining whether a target frequency point consistent with a pre-stored frequency point exists in the frequency points corresponding to each note. If yes, go to step 206, otherwise, end.
Whether a target frequency point exists in the frequency points corresponding to each note of the audio to be played can be determined. For example: and determining whether the target frequency point exists in the first frequency point and the second frequency point or not if the first note corresponds to the first frequency point and the second note corresponds to the second frequency point. The target frequency point is consistent with the pre-stored frequency point, for example: if the pre-stored frequency point is the first frequency point or the second frequency point, it can be determined that a target frequency point exists in the frequency points corresponding to each note of the audio to be played, otherwise, the target frequency point does not exist.
And step 206, acquiring the target loudness corresponding to the target frequency point according to the corresponding relation between the pre-stored frequency point and the loudness.
When a crack exists on a display screen of the mobile terminal and the sound production effect of the mobile terminal is poor, namely when noise or sound breaking exists in sound produced by the mobile terminal, the loudness corresponding to the pre-stored frequency point is a first loudness; when the loudness corresponding to the pre-stored frequency point is determined as the target loudness, the occurrence effect of the mobile terminal can be improved. That is, the possibility of the sound emitted from the mobile terminal being a noise or a break sound is reduced.
And when the target frequency point exists, the loudness corresponding to the target frequency point is also the target loudness.
And step 207, controlling the musical notes corresponding to the target frequency points to be played at the target loudness.
When the mobile terminal plays the musical notes corresponding to the target frequency points in the audio to be played, the musical notes corresponding to the target frequency points can be controlled to be played at the target loudness.
In the embodiment of the invention, through the steps, the loudness of the mobile terminal when playing the musical notes corresponding to the target frequency point is controlled to be the target loudness, and the possibility of noise or sound breaking of the sound emitted by the mobile terminal is reduced, so that the sound production effect of the mobile terminal is improved.
