The audio playback circuit includes: audio decoding module, audio signal processing module, the direct module of audio frequency/audio frequency mixing module, power amplifier module and the speaker that connect gradually, wherein, the direct module of audio frequency and audio frequency mixing module are parallelly connected, as follows:
the audio decoding module is used for decoding the audio encoding data received by the electronic equipment to obtain multi-channel audio data in a PCM format, wherein the multi-channel audio data can be stereo.
The audio signal processing module is used for performing sound effect processing on the multi-channel audio data, and the processing mode can adopt sound effect algorithms such as an equalizer and a virtual surround.

For example, an audio frame with the largest energy value may be selected as the first target audio frame from a plurality of audio frames in the first audio signal, and an audio frame with the largest energy value may be selected as the second target audio frame from a plurality of audio frames in the second audio signal.
Of course, for the selection of the first target audio frame and the second target audio frame, based on a set threshold, any audio frame greater than the threshold may be selected as the first target audio frame, and the corresponding second target audio frame is selected from the second audio signal according to the first target audio frame.
Since there are various selection manners of the first target audio frame and the second target audio frame, which are not listed here one by one, as long as one first target audio frame and one second target audio frame can be selected, and then, by obtaining an energy difference between the first target audio frame and the second target audio frame, a frame energy difference is obtained as signal difference information.
After obtaining the first target audio frame and the second target audio frame, step 103 includes:
and determining a target sound effect mode from a plurality of preset sound effect modes according to the frame energy difference.
The target sound effect mode can be selected by comparing the frame energy difference intervals corresponding to the plurality of preset audio modes to obtain the interval where the calculated frame energy difference is located.
In another embodiment, a plurality of third target audio frames may be selected from the first audio signal, a plurality of fourth target audio frames corresponding to the plurality of third target audio frames may be selected from the second audio signal, and energy differences between every two third target audio frames and the fourth target audio frames may be calculated, so as to obtain a plurality of energy differences.
Thus, in this embodiment, the signal difference information comprises a plurality of frame energy differences, wherein step 102 comprises:
determining a plurality of third target audio frames from the first audio signal, and determining a plurality of fourth target audio frames corresponding to the plurality of third target audio frames respectively in the second audio signal;
and calculating the frame energy difference between each third target audio frame and the corresponding fourth target audio frame to obtain a plurality of frame energy differences.
In this embodiment, a plurality of third target audio frames and a plurality of fourth target audio frames may be selected, and the energy difference between each frame of audio frames may be calculated, or all audio frames in the first audio signal and all audio frames in the second audio signal may be selected, and the energy difference between each frame of audio frames may be calculated. Based on this, the number of the third target audio frame and the fourth target audio frame is not limited in this embodiment, and may be selected according to actual requirements as long as the third target audio frame corresponds to the fourth target audio frame and the number of the third target audio frame is consistent with that of the fourth target audio frame.
For example, the target audio frame may be selected according to the above embodiments, for example, the frame energy value is larger, or the energy value is larger than a certain threshold, and the specific selection manner may refer to the above embodiments.
For the energy values of the audio frames in the above embodiments, in some embodiments, the energy value for each audio frame can be obtained in different ways, as follows:
for example, each audio frame has a plurality of sampling points, each sampling point has an energy value, an average energy value of the sampling points can be calculated, and the average energy value is used as the energy value of the audio frame.
For another example, the energy value of the sampling point at the same position can be selected from each audio frame to be used as the energy value representing the audio frame.
Since there are various ways to obtain the energy value of the audio frame, which are not listed here, as long as the frequency characteristic can be reflected by the energy value of the audio frame, all ways to obtain the frame energy of each audio frame can be used in the embodiments of the present application.
In the following embodiments, the energy value of each audio frame is exemplified in a manner that the energy value of the sampling point based on the maximum energy value is used as the energy value of the audio frame, that is, in the following embodiments, the energy value of the audio frame is represented by the maximum energy value selected from a plurality of sampling points, and the calculated energy difference of each frame is used as the frame energy difference representing the frame energy difference between the third target audio frame and the corresponding fourth target audio frame between the sampling point with the maximum energy value in the third target audio frame and the sampling point with the maximum energy value in the corresponding fourth target audio frame.
The following is a formula for calculating the frame energy difference:
d＝20*log10(max(x)/max(y))
where d is the frame energy difference, max (x) is the energy value of the sample point with the largest energy value in the third target audio frame, and max (y) is the energy value of the sample point with the largest energy value in the fourth target audio frame.
After the plurality of frame energy differences are obtained through calculation, there are various ways to select the target audio mode from the plurality of preset audio modes according to the plurality of frame energy differences, and the following description will be given by using specific embodiments.
In some embodiments, the target sound effect mode may be determined according to the number of the plurality of frame energy differences matching each preset sound effect mode, and in this embodiment, after the plurality of frame energy differences are calculated, step 103 may include:

counting the number of frame energy differences corresponding to each preset audio mode;
and determining a target sound effect mode from a plurality of preset sound effect modes according to the number of frame energy differences corresponding to each preset audio mode.
The frame energy difference interval may be divided by an energy difference threshold, for example, based on a first energy difference threshold and a second energy difference threshold, the frame energy difference may be divided into three frame energy difference intervals, and each frame energy difference interval represents a preset audio mode, which is illustrated as follows:
for example, continuing with the sound box example in the above embodiment, when the frame energy difference interval is [0,100], setting the first energy difference threshold to be 30 and the second energy difference threshold to be 60 to divide the frame energy difference into three frame energy difference intervals, which are [0,30), [30,60), [60,100), where [0,30) represents an indoor sound mode, [30,60) represents an outdoor sound mode, and [60,100) represents a hanging sound mode, and when the calculated frame energy difference is 40, dividing the frame energy difference into [30,60) intervals and accumulating the number of frame energy differences corresponding to the [30,60) intervals, and so on, dividing each frame energy difference into intervals according to a numerical value, and accumulating the number of frame energy differences corresponding to each interval, thereby obtaining the number of frame energy differences corresponding to each preset audio mode.
For another example, continuing with the television in the above embodiment, the sound effect modes of the television include a desktop sound effect mode and a wall-mounted sound effect mode, so that only one energy difference threshold needs to be set, for example, the energy difference threshold is set to be 60, when each frame energy difference is divided, the frame energy difference larger than 60 is divided into the wall-mounted sound effect mode, otherwise, the frame energy difference is divided into the desktop sound effect mode, and then the number of the frame energy differences corresponding to the desktop sound effect mode and the number of the frame energy differences corresponding to the wall-mounted sound effect mode are counted.
Based on this, it should be noted that the above examples are only used to illustrate the dividing form between the frame energy difference regions and the dividing manner of each frame energy difference calculated according to the pair of frame energy difference regions, and the specific values are also used only for illustration and are not used to limit the solution of the embodiment of the present application, wherein the energy difference threshold values used to divide the frame energy difference regions may be set as values and numbers according to the actual situations of different electronic devices, and may also be discontinuous between the frame energy difference regions.
In this embodiment, a plurality of frame energy differences are divided among the frame energy difference regions, and the number of frame energy differences of each frame energy difference region is calculated, that is, the number of frame energy differences corresponding to each preset sound effect mode is obtained, and then the degree of influence of environmental factors on the first audio signal can be reflected from the number corresponding to each preset sound effect mode.
There are various ways to select the target sound effect mode based on the number, such as:
in an embodiment, determining a target audio mode from a plurality of preset audio modes according to the number of frame energy differences corresponding to each preset audio mode includes:
and determining the preset sound effect mode with the maximum corresponding frame energy difference as the target sound effect mode.
The preset sound effect modes with the largest number can be selected as the target sound effect modes, and therefore one preset sound effect mode can be selected from the preset sound effect modes to serve as the target sound effect mode.
In another embodiment, the plurality of preset sound effect modes comprise a desktop sound effect mode and a wall sound effect mode;
counting the number of frame energy differences corresponding to each preset audio mode, and determining the preset audio mode with the largest number of corresponding frame energy differences as a target audio mode, wherein the method comprises the following steps:

and when the ratio of the first quantity to the second quantity is greater than a preset threshold value, determining the desktop sound effect mode as a target sound effect mode.
