The application will be further described by the description of embodiments with reference to the accompanying drawings.
The present embodiment provides a volume adjustment method, as shown in fig. 2 and fig. 3, including:
s10, acquiring a sound source data set corresponding to the target equipment.
Specifically, the sound source data set includes original sound source data and reference sound source data, and the target device is a terminal device for playing the sound source data, for example, a smart television or the like. The original sound source data is data used by the target device to play as audio information, for example, the original sound source data is audio data sent to the target device by an external signal source, or the external signal source sends audio information in video data of the target device. The reference sound source data is sound source data picked up by the electronic device when the target device plays the original sound source data, where the electronic device may be a device for running the volume adjustment method provided in this embodiment, or may be a device connected to a device for the volume adjustment method provided in this embodiment, and when the electronic device is a device connected to a device for the volume adjustment method provided in this embodiment, the electronic device transmits the reference sound source data to the device for the volume adjustment method provided in this embodiment after picking up the parameter sound source data. In a specific implementation manner of this embodiment, the electronic device may be a smart phone.
In one implementation manner of this embodiment, the original sound source data is sound source data played by the target device, and the reference sound source data is sound source data obtained based on the original sound source data played by the target terminal device. Correspondingly, the acquiring the sound source data set corresponding to the target device specifically includes:
acquiring original sound source data of the target equipment through network communication, and picking up reference sound source data of the target equipment through an audio pick-up device;
and taking the sound source data set formed by the acquired original sound source data and the reference sound source data as the sound source data set corresponding to the target equipment.
Specifically, when the reference sound source data is the original sound source data played by the target device, the audio pick-up device picks up the sound source data. In other words, after the target device acquires the original sound source data, the target device plays the original sound source data and transmits the original sound source data to the electronic device (for example, a smart phone or the like) for running the volume adjustment method provided in this embodiment through network communication, and the electronic device receives the original sound source data and picks up the sound source data played by the target device through the audio pickup device, so as to obtain the reference sound source data.
In one implementation manner of this embodiment, since the reference audio source data is obtained by picking up the original audio source data by the audio pickup device, the similarity between the audio content corresponding to the original audio source data and the audio content corresponding to the reference audio source data may satisfy a preset condition, where the preset condition may be preset, and is used to measure whether the audio source data picked up by the pickup device may be used as a basis of the reference audio source data; when the similarity of the audio content corresponding to the audio data picked up by the pick-up device and the audio content corresponding to the original audio data meets a preset condition, the audio data picked up by the pick-up device can be used as reference audio data; on the contrary, when the similarity of the audio content corresponding to the audio data picked up by the pickup device and the audio content corresponding to the original audio data does not meet the preset condition, the audio data picked up by the pickup device cannot be used as the reference audio data. In a specific implementation manner of this embodiment, the similarity between the audio content corresponding to the original audio source data and the audio content corresponding to the reference audio source data is greater than a preset threshold, where the preset threshold may be preset, for example, 95%.
In addition, the reference sound source data is picked up by the audio pick-up device, and when the pick-up device picks up the reference sound source data, the pick-up device picks up the environmental sound of the environment where the target device is located, so that the reference sound source data carries noise, and therefore, the environmental parameters of the original sound source data are higher than those of the reference sound source data. For example, the pickup device picks up the user speaking voice or the like at the time of picking up the reference sound source data.
In one implementation manner of the present embodiment, in order to quickly acquire reference sound source data, before acquiring a sound source data set corresponding to a target device, an electronic device configured to execute the volume adjustment method provided by the present embodiment communicates with the target device, and negotiates a playing time period of the original sound source data; the target device plays the original sound source data in the playing time period, and the electronic device picks up the sound source data through the audio pick-up device (e.g. a pickup, a microphone, etc.) in the playing time period to obtain the reference sound source data corresponding to the target device.
In one implementation manner of the present embodiment, in order to improve the accuracy of the playing volume of the target device, the electronic device for executing the volume adjustment method provided in the present embodiment of the present invention may execute the volume adjustment method provided in the present embodiment once every preset time interval. For this reason, the target device negotiates with the electronic device for an interval time for executing the volume adjustment method provided in the present embodiment at an interval when it is connected to the electronic device, and for a time for executing the volume adjustment method provided in the present embodiment for the first time; the electronic device runs the volume adjustment method provided by the embodiment based on the time and the interval time of the first execution, and the target device transmits the original sound source data to the electronic device based on the time and the interval time of the first execution, so that the electronic device can acquire the original sound source data and the reference sound source data each time. Of course, in practical application, when the electronic device and the target device carry the time and the interval time of the first execution, the playing duration of the original sound source data is obtained each time the volume adjustment method provided in this embodiment is operated, so that the electronic device can determine the picking duration of playing the audio data by the electronic device each time. In addition, the electronic device can also pick up the sound source data played by the target device in real time, so that the volume of the target device is adjusted in real time. And when the electronic equipment is disconnected with the target equipment, the electronic equipment automatically stops running the volume adjusting method provided by the embodiment.
S20, determining the environmental parameters of the reference sound source data based on the sound source data set.
Specifically, the environmental parameter is used for reflecting environmental information of the terminal device acquiring the reference sound source data, where the environmental information may include a distance between the terminal device acquiring the reference sound source data and the target device, environmental noise of an environment where the terminal device acquiring the reference sound source data is located, and the like. In one implementation of this embodiment, when determining an environmental parameter based on a sound source data set, the signal strength and the signal-to-noise ratio of reference sound source data are used as influencing factors of the environmental parameter, and the environmental parameter is determined by comparing sound source error information based on the original sound source data and the reference sound source data. Thus, in one implementation manner of this embodiment, the determining, based on the sound source data set, the environmental parameter of the reference sound source data specifically includes:
determining sound source error information of the target device based on the original sound source data and the reference sound source data;
and determining the environmental parameters of the reference sound source data based on the sound source error information and the reference sound source data.
Specifically, the audio error information is used to reflect audio content that is different from the original audio data in the reference audio data. When the sound source error information of the target equipment is determined, the original sound source data are standard sound source data corresponding to the reference sound source data, and the sound source error information are difference audio information of the reference sound source data relative to the corresponding standard sound source data. In other words, the sound source error information is audio information different from the original sound source data in the reference sound source data.
In one implementation manner of this embodiment, the determining, based on the original sound source data and the reference sound source data, sound source error information of the target device specifically includes:
performing adaptive filtering processing on the reference sound source data to obtain filtered sound source data;
and acquiring error signals of the original sound source data and the filtered sound source data to obtain sound source error information of the target equipment.
Specifically, the adaptive filtering is a finite impulse response digital filtering method with adaptively adjustable parameters, and the input signal vector of the adaptive filtering is determined based on a reference sound source signal, for example, the reference sound source signal is sampled at different moments. In other words, when the adaptive filtering processing is performed on the reference sound source data, the reference sound source signal is first sampled at different moments to obtain an input signal, and then the input signal is adaptively filtered to obtain filtered sound source data, wherein the filtered sound source data is equal to the linear weighted sum of elements of the input signal.
For example, the input signal X (n) constitutes a sampled signal vector for the sampled signal X (n):
X(n)＝[x(n),x(n-1),x(n-2),…x(n-L+1)]
then, the filtered sound source data y (n) can be expressed as:
y(n)＝W(n) T X(n)
wherein W (n) is an x (n) weight coefficient.
Further, after determining the expression of the filtered sound source data, weight coefficients in the expression of the filtered sound source data may be learned based on a steepest descent method, and filtered sound source data corresponding to the reference sound source data may be determined based on the learned weight coefficients. Correspondingly, in an implementation manner of this embodiment, performing adaptive filtering processing on the reference sound source data to obtain filtered sound source data specifically includes:
determining a convergence factor of adaptive filtering corresponding to the reference sound source data based on a steepest descent method;
and determining the filtered sound source data based on the convergence factor and the reference sound source data.
Specifically, the steepest descent method is to determine a convergence factor of the adaptive filtering based on a steepest download principle of minimum mean square error and gradient estimation, wherein an objective function of the steepest descent method may be:
J(n)＝E[e(n)] 2
e(n)＝d(n)-y(n)
y(n)＝W(n) T X(n)
X(n)＝[x(n),x(n-1),x(n-2),...x(n-L+1)]
wherein, the error function corresponding to the e (n) error signal, X (n) is a sampling signal X (n) to form a sampling signal vector, X (n) is a sampling signal at the n-th moment, X (n-1) is a sampling signal at the n-1-th moment, d (n) is original sound source data, and L+1 represents the number of the sampling signals.
The convergence factor of the adaptive filtering is used for determining a weight coefficient corresponding to the reference sound source data, wherein the latter weight coefficient vector can be obtained from the weight coefficient vector of the previous moment, the error information of the previous moment, the input signal vector of the previous moment and the convergence factor of the adaptive filtering. For example, where the weight coefficient vector of n+1 is W (n+1) and the weight coefficient vector of n is W (n) at two adjacent times n+1 and n, then the relationship between W (n+1) and W (n) can be expressed as:
wherein,as the partial derivative of the error function, it can be used μX (n) T e (n) instead, the corresponding relationship of W (n+1) to W (n) may be expressed as:
W(n+1)＝W(n)+μX(n) T e(n)
where μ represents the adaptive filter convergence factor.
Further, after determining the convergence factor of the adaptive filtering, filtered sound source data corresponding to the reference sound source data may be determined based on the convergence factor of the adaptive filtering, so that sound source error information corresponding to the target device may be determined, where the sound source error information is error information of the original sound source data and the filtered sound source data. For example, the filtered source data is denoted as y (n), the original source data is denoted as d (n), and then the error signal is: e (n) =d (n) -y (n).
In an implementation manner of this embodiment, the determining, based on the audio error information, the environmental parameter of the reference audio data specifically includes:
acquiring the mean square error corresponding to the reference sound source data;
and determining environmental parameters of the reference sound source data based on the mean square error, the sound source error information and the reference sound source data.
Specifically, the mean square error is the mean square error of each signal point included in the reference sound source data, where the calculation formula of the mean square error may be:
wherein n represents the number of sampling signals included in the reference audio source data, x i Representing the i-th sampling signal.
After the mean square error is obtained, calculating an environmental parameter based on the mean square error, the sound source error information and the reference sound source data, wherein a calculation formula of the environmental parameter may be:
J(n)＝E[e(n)] 2
where S represents the mean square error, E (n) represents the source error information, and X (n) represents the sampling signal X (n) to constitute a sampling signal vector.
S30, adjusting the volume of the target equipment based on the sound source data set and the environment parameters.
Specifically, the volume refers to the volume set by the target device and used for playing the original audio data, and correspondingly, the volume adjustment of the target device refers to the volume adjustment used for playing the original audio data. The adjusting the volume of the target device may be that the electronic device running the volume adjusting method provided in this embodiment sends an adjusting instruction to the target device, so that the target device adjusts the volume based on the adjusting instruction; the electronic device running the volume adjustment method provided in this embodiment may send a target volume to the target device, where the target device directly adjusts its own configured volume to be the target volume, or determines whether volume adjustment is needed based on the target volume and its own configured current volume, and when volume adjustment is needed, automatically adjusts the configured volume to be the target volume; the electronic device running the volume adjustment method provided in this embodiment may send an adjustment coefficient to the target device, where the target device determines a target volume based on its own configured current volume and the adjustment coefficient, and adjusts its own configured current volume to the target volume. In the embodiment, the volume data of the target device is adjusted based on the sound source data set and the environmental parameter, and the signal-to-noise ratio of the reference sound source data and the signal strength corresponding to the original sound source data are used as the influence factors of the environmental parameter, because the signal strength can reflect the distance between the electronic device (such as a smart phone carried by a user) and the target device (such as a smart television), the signal-to-noise ratio can reflect the interference degree of the current environmental noise on the sound source, and the accuracy of the volume adjustment factor can be improved by adopting the signal strength and the signal-to-noise ratio as the influence factors.
In one implementation manner of this embodiment, adjusting the volume of the target device based on the sound source data set and the environmental parameter specifically includes:
determining sound source error information of the target device based on the original sound source data and the reference sound source data;
determining a volume adjustment factor of the target device based on the sound source error information, the environmental parameter, and the original sound source data;
and adjusting the volume of the target equipment based on the volume adjustment factor.
Specifically, the audio error information is the same as the audio error information described above, and the determination process is the same, which is not described herein, and reference may be made to the description of the audio error information described above. The volume adjustment factor is used for adjusting the volume of the target device, wherein a calculation formula of the volume adjustment factor may be:
wherein μ is a convergence factor, Q (n) is an environmental parameter, e (n) is sound source error information, S is a mean square error, X (n) is a sampling signal X (n) to form a sampling signal vector, Y (n) is original sound source data, and B (n) is a volume adjustment factor.
And after the volume adjustment factor is acquired, the volume adjustment factor is taken as an adjustment proportion to adjust the volume of the target equipment. For example, B (n) =1.5, for example, represents that the actual volume is 1.5 times the ideal volume, and the actual volume needs to be reduced by 1.5 times. In addition, in practical application, when the target device is connected with the sound box, the adjusted volume can be sent to the sound box, so that the sound box plays the original sound source data according to the volume. For example, the target device is connected with a sound box configured on the refrigerator, the target device sends the sound volume to the air conditioner, and the sound volume of the sound box is adjusted through the air conditioner, so that the sound volume of the sound box is matched with the adjusted sound volume of the target device, and the target device plays the adjustment of the sound volume.
