[0021] Figure 1This is a flow chart of a mixing method provided in an embodiment of the present invention. The embodiment of the present invention is applicable to the case of adjusting mixing. The method can be executed by a mixing system, and the mixing system can include at least two gain controllers and at least two knobs. In a specific embodiment, the mixing method can be described by the mixing system. If the mixing system includes two gain controllers and two knobs, refer to Figure 1 The method of the embodiment of the present invention specifically includes the following steps:

[0022] S110: Acquire a sampling value of a first knob and a sampling value of a second knob.

[0023] Among them, the sampling value is a parameter used to measure the change of sound fluctuation; the sampling value of the first knob refers to the parameter corresponding to the first knob that controls the sound change; the sampling value of the second knob refers to the parameter corresponding to the second knob that controls the sound change.

[0024] Specifically, the parameter for controlling the sound change of the first knob and the parameter for controlling the sound change of the second knob at the current moment are read from the first knob and the second knob respectively.

[0025] S120 , determining the gain of the first gain controller and the gain of the second gain controller respectively according to the sampling value of the first knob and the sampling value of the second knob.

[0026] The gain controller is actually a kind of dynamic processor, and its gain varies with the change of the signal; the first gain controller and the second gain controller are gain controllers for outputting different gain amounts respectively.

[0027] Specifically, after obtaining the sampling value of the first knob and the sampling value of the second knob, the maximum-scale sampling value of the first knob and the maximum-scale sampling value of the second knob are further obtained, wherein the maximum-scale sampling value of the first knob and the maximum-scale sampling value of the second knob can be directly read from the first knob and the second knob, and the first sampling ratio is obtained by calculating the ratio of the sampling value of the first knob to the maximum-scale sampling value of the first knob, and at the same time, the second sampling ratio is obtained by calculating the ratio of the sampling value of the second knob to the maximum-scale sampling value of the second knob, and finally, the gain of the first gain controller is determined to be obtained by multiplying the first sampling ratio and the second sampling ratio, and the gain of the second gain controller is determined to be obtained by subtracting the product of the first sampling ratio and the second sampling ratio from 1.

[0028] Exemplarily, the gain of the first gain controller and the gain of the second gain controller are specifically determined as shown in Table 1.

[0029]

[0030] S130 , adjusting the first audio signal by using the gain of the first gain controller, and adjusting the second audio signal by using the gain of the second gain controller.

[0031] The audio signal is a signal for representing a mechanical wave and is an information carrier of changes in the wavelength and intensity of the mechanical wave; the first audio signal and the second audio signal are two different audio signals.

[0032] Specifically, after determining the gain of the first gain controller and the gain of the second gain controller, the first audio signal is adjusted by the gain of the first gain controller, and the second audio signal is adjusted by the gain of the second gain controller. Furthermore, the method of adjusting the first audio signal by the gain of the first gain controller and adjusting the second audio signal by the gain of the second gain controller includes: when the first knob is rotated clockwise, the "gain of the first gain controller" increases, the gain of the first gain controller increases, and the volume of the first audio signal increases. The "gain of the second gain controller" decreases, the gain of the second gain controller decreases, and the volume of the second audio signal decreases; when the first knob is rotated counterclockwise, the "gain of the first gain controller" decreases, the gain of the first gain controller decreases, and the volume of the first audio signal decreases. The result of "the gain of the second gain controller" becomes larger, the gain of the first gain controller becomes larger, and the volume of the second audio signal becomes larger; when the second knob is rotated clockwise, the results of "the gain of the first gain controller" and "the gain of the second gain controller" both become larger, the gains of the first gain controller and the second gain controller become larger, and the volume of the first audio signal and the volume of the second audio signal both become larger; when the second knob is rotated counterclockwise, the results of "the gain of the first gain controller" and "the gain of the second gain controller" both become smaller, the gains of the first gain controller and the second gain controller become smaller, and the volume of the first audio signal and the volume of the second audio signal both become smaller.

[0033] S140: Mix the adjusted first audio signal and the adjusted second audio signal.

[0034] Mixing refers to integrating sounds from multiple sources into a stereo track or a mono track.

[0035] Specifically, after the first audio signal and the second audio signal are controlled and adjusted by the first knob and the second knob, the controlled and adjusted first audio signal and the second audio signal are superimposed and mixed to finally obtain a mixed signal.

[0036] The embodiment of the present invention obtains the sampling value of the first knob and the sampling value of the second knob; determines the gain of the first gain controller and the gain of the second gain controller respectively according to the sampling value of the first knob and the sampling value of the second knob; adjusts the first audio signal by the gain of the first gain controller, and adjusts the second audio signal by the gain of the second gain controller; and mixes the adjusted first audio signal with the adjusted second audio signal. In the above technical solution, the gain of the gain controller is determined respectively by the sampling value of the first knob and the second knob, and then the audio signal is adjusted by the gain, and the adjusted audio signal is further mixed to avoid noise generated by the gain change of the gain controller corresponding to the regulator during the volume adjustment process of the audio signal.

[0037] Figure 2 This is another flow chart of a mixing method provided in an embodiment of the present invention. Based on the above embodiment, the method further optimizes the mixing of the adjusted first audio signal and the adjusted second audio signal by determining the gain of the first gain controller according to the sampled value of the first knob and the sampled value of the second knob, determining the gain of the second gain controller according to the sampled value of the first knob and the sampled value of the second knob, and further optimizing the mixing of the adjusted first audio signal and the adjusted second audio signal. The method specifically includes the following steps:

[0038] S210: Acquire a sampling value of a first knob and a sampling value of a second knob.

[0039] Specifically, the parameter for controlling the sound change of the first knob and the parameter for controlling the sound change of the second knob at the current moment are read from the first knob and the second knob respectively.

[0040] S220 : Determine the gain of the first gain controller according to the sampling value of the first knob and the sampling value of the second knob.

[0041] Specifically, the first parameter is calculated based on the sampling value of the first knob and the maximum range sampling value of the first knob; and the second parameter is calculated based on the sampling value of the second knob and the maximum range sampling value of the second knob; the gain gear of the first gain controller is determined based on the product of the first parameter and the second parameter; and the gain of the first gain controller corresponding to the gain gear of the first gain controller is obtained.

[0042] S230 : Determine the gain of the second gain controller according to the sampling value of the first knob and the sampling value of the second knob.

[0043] Specifically, the first parameter is calculated based on the sampling value of the first knob and the maximum range sampling value of the first knob; and the second parameter is calculated based on the sampling value of the second knob and the maximum range sampling value of the second knob; the gain gear of the second gain controller is determined based on the difference between 1 and the first parameter and the product of the second parameter; and the gain of the second gain controller corresponding to the gain gear of the second gain controller is obtained.

[0044] S240: Adjust the gain of the first audio signal by using a first gain controller.

[0045] Specifically, after determining the gain of the first gain controller and the gain of the second gain controller, the first audio signal is controlled by the gain of the first gain controller. Furthermore, if the gain design range of the first gain controller is minA dB to maxA dB, the gain gear is designed to be n gears, namely 0, 1, 2, 3... (n-1), each gear corresponds to a value from minA dB to maxA dB, and the sequence of this value can be an arithmetic sequence with equal intervals or an increasing sequence with unequal intervals. Gear 0 corresponds to minA dB, and gear (n-1) corresponds to maxA dB. The calculated result of "the gain of the first gain controller" is divided by "1 / n", and the integer part of the quotient is the corresponding gear. Finally, the first knob is adjusted according to the determined gear to ultimately control the first audio signal.

[0046] For example, if the gain gear of the first gain controller is designed to be 10 gears, the result of "the gain of the first gain controller" is 22%, and the integer part of the quotient of 22% divided by 1 / 10 is 2, then the corresponding gain gear is 2, and the gain controller A is set to the value corresponding to 2, and the first knob is further adjusted to the position of 2 to control the first audio signal.

[0047] S250: Adjust the gain of the second audio signal by using a second gain controller.

[0048] Specifically, after determining the gain of the first gain controller and the gain of the second gain controller, the second audio signal is controlled by the gain of the second gain controller. Furthermore, the gain design range of the second gain controller is minBdB~maxB dB, and the gain gear is designed to be m gears, namely 0 gear, 1 gear, 2 gear, 3 gear...(m-1) gear, each gear corresponds to a value in minBdB~maxB dB, and the sequence of this value can be an arithmetic sequence with equal intervals or an increasing sequence with unequal intervals. Gear 0 corresponds to minB dB, and gear (m-1) corresponds to maxB dB. The calculated result of "the gain of the second gain controller" is divided by "1 / m", and the integer part of the quotient is the corresponding gear. Finally, the second knob is adjusted according to the determined gear to ultimately control the second audio signal.

[0049] Exemplarily, the gain gear of the second gain controller is designed to be 10 gears, the result of "the gain of the second gain controller" is 22%, and the integer part of the quotient of 22% divided by 1 / 10 is 2, so the corresponding gain gear is 2 gears, and the second gain controller is set to the value corresponding to gear 2, and the second knob is further adjusted to the position of gear 2 to control the second audio signal.

[0050] S260: Input the adjusted first audio signal and the adjusted second audio signal into a mixer for superposition to obtain mixed audio.

[0051] Among them, mixed audio refers to the audio signal that integrates sounds from multiple sources into a stereo track or a mono track.

[0052] Specifically, after obtaining the controlled first audio signal and the controlled second audio signal, the controlled first audio signal and the controlled second audio signal are input into a mixer to superimpose the audio signals to obtain mixed audio.

[0053] S270 , inputting the mixed audio and the gain of the third gain controller into a monitoring amplifier for monitoring amplification to obtain monitoring audio.

[0054] The gain of the third gain controller is a fixed gain. The advantage of such a setting is that the noise generated by the gain change of the gain controller corresponding to the regulator is reduced.

[0055] Specifically, after obtaining the mixed audio of the controlled first audio signal and the controlled second audio signal from the mixer, the mixed audio is input into the monitoring amplifier, and at the same time, the fixed gain of the third gain controller is input to obtain the final monitoring audio, and the monitoring audio is monitored and amplified by the monitoring amplifier.

[0056] The embodiment of the present invention obtains the sampling value of the first knob and the sampling value of the second knob; determines the gain of the first gain controller according to the sampling value of the first knob and the sampling value of the second knob; determines the gain of the second gain controller according to the sampling value of the first knob and the sampling value of the second knob; adjusts the first audio signal by the gain of the first gain controller; adjusts the second audio signal by the gain of the second gain controller; inputs the adjusted first audio signal and the adjusted second audio signal into the mixer for superposition to obtain mixed audio; inputs the mixed audio and the gain of the third gain controller into the monitoring amplifier for monitoring amplification to obtain monitoring audio. In the above technical solution, the monitoring audio is obtained by further mixing the adjusted audio and inputting it into the monitoring amplifier for monitoring amplification with the gain of the third gain controller. The gain controller C of the monitoring amplifier is set to a fixed value, and the noise generated by the gain change of the gain controller corresponding to the regulator is reduced.
