Additionally, the use of “based on” means open and inclusive, as the process, step, calculation, or other action based on one or more recited conditions or values can in practice be based on additional conditions or values beyond those recited.

[0048] In this application, the word "exemplary" is used to mean "serving as an example, instance, or illustration." Any implementation described as "exemplary" in this application is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the application. In the following description, for purposes of explanation, specific details are set forth. It is apparent to those skilled in the art that the present application can be practiced without using these specific details. In other instances, well-known structures and processes are not described in detail in order to avoid obscuring the description of the application. Thus, the present application is not intended to be limited by the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0049] In one aspect, referring to Figure 1 and Figure 2 , the embodiments of the present application provide an atmosphere building audio control method, comprising the following steps:

[0050] S10, obtaining the number of audio output devices in the live environment.

[0051] In S10, the number of audio output devices in the live environment usually includes at least one.

[0052] S20, based on each audio output device, starting a group of designated receiving devices, and based on the at least one group of started designated receiving devices, performing cancellation processing on the audio information output by the audio output device; each group of designated receiving devices includes two designated receiving devices.

[0053] In S20, when the audio output device includes two or more, the designated receiving devices corresponding to different audio output devices can be shared. In a specific example, when there are two audio output devices, the two audio output devices correspond to two groups of designated receiving devices, and the two groups of designated receiving devices each include the same designated receiving device. At this time, the two groups of designated receiving devices include a total of three designated receiving devices. The live environment can include multiple designated receiving devices.

[0054] S30, continue to obtain the remaining audio information, and based on the obtained remaining audio information, obtain the distance between the audio information generation place and the closest designated receiving device.

[0055] In S30, the remaining audio information is a specific audio content, which can be a dialogue, music, etc. In the distance between the acquisition audio information generation place and the nearest designated receiving device, the designated receiving device here is already started, and can be a corresponding audio output device or an additionally started audio output device.

[0056] The remaining audio device information generation place is a specific location where the remaining audio information is generated. In this embodiment, it is not necessary to determine the specific location of the remaining audio information generation place, but only to determine the distance between the remaining audio information generation place and the nearest designated receiving device.

[0057] In S40, it is determined whether the acquired distance is within a first preset threshold range.

[0058] In S40, the first preset threshold range can be set according to actual conditions, such as the size of the live environment, the number of people in the environment, etc. The larger the size of the live environment, the larger the first preset threshold range can be. The more people in the environment, the smaller the first preset threshold range can be.

[0059] In S50, when it is determined that the acquired distance is within the first preset threshold range, the atmosphere parameters are adjusted based on the remaining audio information according to a preset rule. When it is determined that the acquired distance is not within the first preset threshold range, an end processing can be performed, or the steps of S10-S50 are repeated.

[0060] Taking the application scenario of KTV as an example, adjusting the atmosphere parameters based on the remaining audio information according to a preset rule can include: when the chorus part of a song or the information of a user singing loudly is received, all the lights can be automatically brightened or the flashing frequency of the lights can be enhanced; when the volume does not reach a peak (such as a drum point), the lights can be quickly flashed to create a “pulse” feeling; in the quiet part of the song prelude or interlude, the lights can be automatically dimmed and changed to soft color tones to create a relatively suitable atmosphere; the flashing frequency of the color spotlight and the laser light can be synchronized with the song BPM according to the beat speed of the audio, the fast flashing for fast songs and the slow color flow or breathing effect for slow songs; the video background can be switched and the flow speed and rhythm can be matched according to the beat speed of the audio; when the system recognizes a fast rhythm dance song, it can automatically switch to a “dynamic” light mode, and when it recognizes a slow rhythm love song, it can switch to a “romantic” mode, etc.

[0061] Through the arrangement of the above-mentioned embodiments, when there are multiple audio output devices in the live environment, the sound output by the multiple audio output devices can be respectively processed for deletion, thereby reducing the influence of multiple types of audio information in the live environment on subsequent atmosphere control. Further, the position of the remaining audio data and the closest distance of the closest specified receiving device are obtained, and then the closest distance is used to select the atmosphere parameter for controlling the live environment, thereby creating different atmospheres. By selectively controlling the atmosphere parameter of the live environment according to the distance, the input information can be reduced to avoid the situation of misjudgment caused by too many sound sources in the live environment, thereby making the final presented atmosphere more consistent with the expectations of the controller, and improving the user experience.

[0062] In some embodiments, after the S30 step of obtaining the remaining audio information, the following steps are further included:

[0063] T10, based on the remaining audio information received by the at least two specified receiving devices, positioning the position where the remaining audio information is generated.

[0064] In T10, the specific position where the remaining audio information is generated can be obtained through two or more receiving devices. The T10 step is independent of the subsequent steps S30, S40 and S50, and does not conflict with each other.

[0065] Further, in the S50 step, based on the remaining audio information, the atmosphere parameter is adjusted according to the preset rule: based on the position of the remaining audio information, the atmosphere parameter is adjusted according to the preset rule.

[0066] Through the arrangement of the above-mentioned embodiments, the position where the remaining audio information is generated is accurately determined, and then according to the determined position, the atmosphere can be further created in a targeted manner, such as gathering the light towards the specific position, to further improve the user experience.

[0067] In some embodiments, in the T10 step, based on the remaining audio information received by the at least two specified receiving devices, the position where the remaining audio information is generated is positioned, including:

[0068] T101, obtaining the remaining audio information received by the at least four specified receiving devices;

[0069] T102, obtaining the time difference of the remaining audio information received by any two specified receiving devices;

[0070] In T102, the time difference between one specified receiving device and any other two specified receiving devices in T101 is obtained, to obtain three time differences in the subsequent step T103.

[0071] T103、Based on the obtained time differences, a plurality of ambiguous locations is obtained.

[0072] T104、Obtaining the loudness of the remaining audio information received by the four specified receiving devices, and based on the loudness differences and the plurality of ambiguous locations, obtaining the precise location.

[0073] Based on the obtained time differences, a plurality of ambiguous locations can be obtained in a conventional manner. To illustrate with a specific example, there are four receiving devices (M1, M2, M3, M4), and the time differences t between all pairs of receiving devices are calculated.

[0074] For a pair of receiving devices (e.g., M1 and M2):

[0075] The cross-correlation function of the two signals is calculated. The cross-correlation function describes how similar two signals are when one is shifted relative to the other.

[0076] The time delay (τ) at which the cross-correlation function peaks is the most likely time difference in which the sound arrived at M1 and M2. That is: t 12 = argmax(R 12 (τ)) where R 12 (τ) is the cross-correlation function of the M1 and M2 signals.

[0077] This process is repeated for all pairs of receiving devices relative to a reference receiving device to obtain a set of time differences [t 12 , t 13 , t 14 ].

[0078] The position is calculated using the hyperbolic intersection method, because the locus of points for which the distance difference to a fixed point is constant is a hyperbola.

[0079] The coordinates of the receiving devices M1 and M2 are known to be (x1, y1, z1) and (x2, y2, z2), respectively.

[0080] The calculated t 12 is multiplied by the speed of sound c (approximately 343 m / s) to obtain the distance difference d 12 = c *t 12 between the sound source and M1 and M2.

[0081] This distance difference d 12 defines a hyperbola with M1 and M2 as foci, and the sound source must lie on this curve.

[0082] Similarly, t 13 can be used to draw another hyperbola with M1 and M3 as foci.

[0083] The intersection of the two hyperbolas in space is the estimated location of the sound source. In three-dimensional space, at least three hyperbolas (i.e. four receiving devices) are needed to determine a unique intersection point.

[0084] Find a point (x, y, z) by an algorithm (e.g. least square method) such that the total error between the distance difference of the point to each receiving device and the measured distance difference is minimized.

[0085] Then further refine the possible intersection points obtained:

[0086] Calculate relative loudness: Calculate the root mean square (RMS) or short-time energy of the sound source signal at each receiving device as a measure of loudness.

[0087] Theoretical distance attenuation model: According to the sound source position calculated in step three, back-propagate the theoretical distance ri of the sound source to each receiving device.

[0088] Check consistency:

[0089] Sound propagates in a free field, and loudness should be inversely proportional to distance (approximately). Therefore, the receiving device closest to the sound source should receive the signal with the largest loudness.

[0090] Further obtain the possible refined position.

[0091] In some embodiments, the atmosphere-building audio control method further comprises the following steps:

[0092] H10, constructing a three-dimensional coordinate system based on the live environment;

[0093] H20, partitioning the live environment based on the three-dimensional coordinate system;

[0094] After T10, positioning the remaining audio information generation based on the remaining audio information received by at least two designated receiving devices, further comprising the following steps:

[0095] T111, determining the partition in which the received remaining audio information generation is located;

[0096] T112, when it is determined that the received remaining audio information generation is located in the designated partition, continue with the subsequent steps.

[0097] Through the above embodiment, the live environment can be partitioned, for example, the live environment atmosphere control area and other areas. When the remaining audio information generation is located in the designated partition, for example, in the control area, the subsequent atmosphere parameter output operation is continued. Through this setting, the interference from other areas can be further reduced, and the final control effect is better.

[0098] In some embodiments, S20, based on each audio output device, sets a group of designated receiving devices, and based on the set at least one group of designated receiving devices, performs cancellation processing on the audio information output by all audio output devices, specifically comprising the following steps:

[0099] S201, select two designated receiving devices with the same distance from the audio output device as a group of designated receiving devices corresponding to the audio output device.

[0100] In S201, the audio output device is usually specific and stationary, such as a sound system in a KTV. Two designated receiving devices with the same distance from the audio output device can be selected from multiple designated receiving devices, or two designated receiving devices with the same distance from the audio output device can be specially set.

[0101] S202, delete the same audio information received by the two designated receiving devices in the group of designated receiving devices, and the same audio information includes the same content, timbre, frequency and / or loudness.

[0102] In S202, the same audio information can be the same content, the same timbre, the same frequency or the same loudness, and can include two, three or all of them.

[0103] Through the setting of the above embodiments, the sound output by the specific audio output device in the environment, such as the sound system, can be deleted, thereby reducing the influence of multiple types of sound in the live environment on subsequent atmosphere control.

[0104] In some embodiments, S50, when it is determined that the obtained distance is within the first preset threshold range, based on the remaining audio information, before adjusting the atmosphere parameter according to the preset rule, the following steps are further included:

[0105] S501, determine whether the obtained remaining audio information is the first occurrence within a preset time period.

[0106] In S501, the preset time period can be set according to actual conditions. In the specific example of a KTV, the time from the start of each performance is calculated as the preset time period. When determining whether it is the first occurrence, repeated judgment can be made based on the content.

[0107] S502, when it is determined that the obtained remaining audio information is not the first occurrence within the preset time period, obtain the decibel difference between the subsequent remaining audio information and the last audio information with the same information.

[0108] S503, when determining that the decibel difference between the subsequent remaining audio information and the audio information with the same information last time is within the second preset threshold range, using the atmosphere parameter output at the time when the audio information with the same information last time is output.

[0109] S504, when determining that the decibel difference between the subsequent remaining audio information and the audio information with the same information last time exceeds the second preset threshold range, switching to a new preset rule to adjust the atmosphere parameter.

[0110] Through the above-mentioned embodiment, the atmosphere parameter can be adjusted in the case of receiving the same content at different times and different stages for the same user. In the specific example, the adjustment of the atmosphere parameter is also based on the preset rule, such as presetting multiple rules for the same content, and then replacing the rules in sequence based on the same content during adjustment. The specific content can be the volume peak, the song prelude or interlude, the audio beat speed, etc.

[0111] In some embodiments, S50, after determining that the distance is within the first preset threshold range, based on the remaining audio information, the atmosphere parameter is adjusted according to the preset rule, further comprising the following steps:

[0112] S511, determining whether the acquired remaining audio information is the first time within a preset time period;

[0113] S512, when determining that the acquired remaining audio information is not the first time within a preset time period, acquiring the frequency difference between the subsequent remaining audio information and the audio information with the same information last time;

[0114] S513, when determining that the frequency difference between the subsequent remaining audio information and the audio information with the same information last time is within the third preset threshold range, using the atmosphere parameter output at the time when the audio information with the same information last time is output;

[0115] S514, when determining that the frequency difference between the subsequent remaining audio information and the audio information with the same information last time exceeds the third preset threshold range, switching to a new preset rule to adjust the atmosphere parameter.

[0116] The method provided by the embodiment of the present application for atmosphere building audio control first performs pre-arrangement, acquires the number of audio output devices of a live environment, sets a group of specified receiving devices corresponding to the number of audio output devices, the group of specified receiving devices includes two specified receiving devices, and the two specified receiving devices are the same distance from the corresponding audio output device; then the number of the set specified receiving devices is judged, if the number of the set specified receiving devices is less than 4, then more specified receiving devices are arranged, so that the number of the specified receiving devices reaches 4, and if the number of the set specified receiving devices is not less than 4, then no additional processing is needed.

[0117] In a specific implementation, the first preset threshold range is set according to the size of the live environment and the number of people in the live environment. When the audio information is acquired, the position of the sound is judged based on the specified receiving devices opened in the live environment, if the position of the audio information is the same distance from one group of specified receiving devices, the audio information is eliminated; for the remaining audio information, the distance from the nearest specified receiving device where the audio information is located is acquired, if the distance from the nearest specified receiving device where the audio information is located is in the first preset threshold range, the partition where the audio information is located is further judged, if the partition where the audio information is located is in the control area, it is further judged whether the audio information is the first occurrence, if it is the first occurrence, the atmosphere parameter is adjusted according to the preset rule based on the audio information; if it is not the first occurrence, the decibel difference and the frequency difference between the subsequent remaining audio information and the audio information with the same information last time are acquired; when it is determined that the decibel difference between the subsequent remaining audio information and the audio information with the same information last time is in the second preset threshold range, and it is determined that the frequency difference between the subsequent remaining audio information and the audio information with the same information last time is in the third preset threshold range, the atmosphere parameter output last time when the audio information with the same information is used; when it is determined that the decibel difference between the subsequent remaining audio information and the audio information with the same information last time exceeds the second preset threshold range, or it is determined that the frequency difference between the subsequent remaining audio information and the audio information with the same information last time exceeds the third preset threshold range, a new preset rule is switched for adjusting the atmosphere parameter.

[0118] In another aspect, the embodiment of the present application provides an atmosphere building audio control system, including a memory and a processor, the memory stores a computer program, and the processor executes the computer program to realize the atmosphere building audio control method of any one of the above embodiments.
