Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the prior art, in the development process of a sound system, the structure size is limited, a high-performance loudspeaker cannot be installed frequently, under the existing condition, the front-end DSP sound effect processing is required to be relied on to exert the performance of a loudspeaker as far as possible, different PEQ parameter sets are set according to different volumes, the common DSP sound effect processing scheme is adopted, high-low-frequency boost gain is achieved at low volume, and the low volume hearing is improved; and when the volume is large, the gain of high and low frequencies is reduced to reduce distortion.
The PEQ parameter is set by judging the volume value of the system in the existing scheme, and the scheme has scene defects. When the user adjusts the system volume to the maximum and the input sound source is small, although the output is not large, the DSP algorithm still considers the output to be the maximum, and then a frequency response curve with large volume is applied, so that high and low frequency loss is caused, and the hearing sense is sacrificed.
In order to solve the problems in the prior art, the present embodiment provides a dynamic adjustment method for sound effect frequency response parameters, as shown in fig. 1. The dynamic adjustment method for the sound effect frequency response parameters in the embodiment comprises the following steps:
and S100, acquiring a sound signal, and carrying out loudness analysis on the sound signal to obtain a current frequency response parameter.
In this embodiment, the sound signal is collected in real time by a microphone device. And then, carrying out loudness analysis on the sound signal at preset time intervals to obtain the current frequency response parameter. In specific implementation, the present embodiment may utilize a built-in microphone of the audio device to collect external sound signals in real time, the collection may be implemented by recording, and loudness analysis is performed every 5s of recording, then an average sound pressure of the sound signals is obtained based on a C-weighted (C-weighted is a frequency characteristic simulating high-intensity noise, and dB is usually marked by measurement of C-weighted), a current sound signal is collected by the built-in microphone and subjected to Fast Fourier Transform (FFT) calculation to obtain a loudness value, and a time domain signal is converted into a frequency domain signal. Since the present embodiment may set the plurality of sampling points according to the time interval when the sound signal is collected, the present embodiment may obtain the average loudness value based on the preset sampling points and the loudness value of each sampling point, where the average loudness value is the average sound pressure value, and set the average loudness value as the current frequency response parameter.
It should be noted that, in the embodiment, the time interval for collecting the sound signal is adjustable, and the interval of the loudness value is also adjustable. Because many power amplifiers are provided with I2S for output, because the amplification gain of the power amplifier PWM (pulse width modulation) is controlled by hardware, the actual output of I2S is directly related to sound pressure, and power amplifier signals before the power amplifier enters the PWM for amplification can be collected as reference points, so that the signal collection cost is reduced.
Step S200, obtaining a frequency response reference parameter of a preset frequency response curve, and comparing the current frequency response parameter with the frequency response reference parameter to obtain a comparison result.
After the current frequency response parameter is obtained, in this embodiment, a frequency response reference parameter of a preset frequency response curve is first obtained, and the frequency response reference parameter is provided with multiple groups. And then subtracting the current frequency response parameter from each group of frequency response reference parameters to obtain a loudness difference absolute value, wherein the loudness difference absolute value is the comparison result.
Because the human ear is most sensitive to the loudness in the interval of 500Hz-3kHz, the embodiment can take 500Hz-3kHz as the reference frequency range, and when the average sound pressure is 60/65/70/75/80/85/90dB, a group of electric frequency response curves are respectively debugged and identified. Specifically, a-12 dB _500 Hz-3kHz powder noise signal is input, the volume of the system is adjusted, the average sound pressure is tested by C weighting, an external microphone is used for collecting the current signal and carrying out FFT calculation, and a time domain signal is converted into a frequency domain signal. Sampling sound pressure samples from 500Hz-3kHz according to 1/3 frequency multiplication:
fc＝f0×21/n
with the first frequency point being 500Hz, the eight frequency points 500, 630, 800, 1000, 1250, 1600, 2000, 2500 can be approximately sampled according to the above formula, with the unit being Hz. Calculation formula of average sound pressure:
P＝(P1+P2+P3+...+Pn)/n
when the average sound pressure reaches 60dB, a group of frequency response curves are set by taking the equal frequency response curve as a reference, and the frequency response curve when the average sound pressure is 65/70/75/80/85/90dB is debugged by the same method, so that a plurality of groups of frequency response curves are obtained.
In this embodiment, the comparison result may be obtained by subtracting the current frequency response parameter from each group of frequency response reference parameters, and the comparison result includes an absolute value of a loudness difference obtained by subtracting the current frequency response parameter from each group of frequency response reference parameters.
Step S300, determining a target frequency response parameter according to the comparison result, and applying the target frequency response parameter
The embodiment acquires the minimum value in the absolute value of the loudness difference value and a frequency response curve corresponding to the minimum value; and then, taking the frequency response reference parameter of the frequency response curve corresponding to the minimum value as the target frequency response parameter, and importing the frequency response reference parameter into a processing module for application. As can be seen, in this embodiment, the final target frequency response parameter can be obtained based on the obtained current frequency response parameter and then based on the comparison between the current frequency response parameter and the frequency response reference parameter of the preset frequency response curve.
In one implementation, when a new current frequency response parameter is obtained, the new current frequency response parameter is subtracted from a previous current frequency response parameter to obtain a difference absolute value; comparing the absolute value of the difference value with a preset value; and if the absolute value of the difference is smaller than or equal to the preset value, applying the target frequency response parameter obtained based on the last current frequency response parameter. For example, in this embodiment, the preset value may be set to 5, and if the absolute value of the difference is less than or equal to 5, the frequency response reference parameter of the frequency response curve corresponding to the minimum value obtained after subtracting the current frequency response parameter from the previous current frequency response parameter is used as the target frequency response parameter, that is, when the absolute value of the difference is less than or equal to 5, the target frequency response parameter determined based on the previous current frequency response parameter may be reused.
And when the absolute value of the difference is larger than the preset value, sequentially applying the intermediate state frequency response parameters between the new current frequency response parameters and the target frequency response parameters from the sequence of the new current frequency response parameters and the target frequency response parameters. For example, when the absolute value of the difference is greater than 5, the frequency response parameters between the new current frequency response parameter and the target frequency response parameter determined by the previous current frequency response parameter are sequentially applied. Therefore, the present embodiment may analyze the current frequency response parameter, and may obtain the final target frequency response parameter after comparing the current frequency response parameter with the frequency response reference parameter of the preset frequency response curve, thereby avoiding the problem of failure in some scenes in the prior art, and better conforming to the auditory sensation of human ears.
In summary, the present embodiment provides a dynamic adjustment method for sound effect frequency response parameters, which first obtains a sound signal, and performs loudness analysis on the sound signal to obtain a current frequency response parameter. And then, acquiring a frequency response reference parameter of a preset frequency response curve, and comparing the current frequency response parameter with the frequency response reference parameter to obtain a comparison result. And finally, determining a target frequency response parameter according to the comparison result, and applying the target frequency response parameter. In the embodiment, the loudness analysis is performed, so that the frequency response parameters are determined, frequent change of the frequency response parameters is avoided, and influence on hearing due to overlarge frequency response parameter difference is avoided.
