Fig. 1 illustrates a method of audio processing according to one embodiment. In the present embodiment, an audio processing method 100 is described by way of different examples. The audio processing method provided in this embodiment is executed on a mobile terminal, and the mobile terminal may be any terminal device such as a computer, a tablet computer, and an electronic device. The method comprises the steps of executing a software application on a processor of the mobile terminal and rendering the software application on a touch display of the mobile terminal to obtain a graphical user interface, wherein content displayed by the graphical user interface at least partially comprises a part or all of a game scene, and the game scene comprises a game picture and at least one virtual object.

The virtual object may be a virtual object for enemy camping or a virtual object for own camping, and the virtual object may implement corresponding behaviors in the game scene in response to the operation of the user, for example, the user may control the virtual object to perform actions such as walking, running, squatting, lying prone, attacking, shooting, and the like in the game scene, which is not limited herein. When other virtual objects in the game perform corresponding actions in the game scene, different sounds are triggered and generated, and the sounds are received by the current virtual object.

As shown in fig. 2, in the present embodiment, the space of the game scene is divided into a plurality of geometric bodies that are connected to each other. The geometric bodies can be cuboids, cubes, parallelepipeds, honeycomb bodies and the like, and can be understood to be spliced with each other, so that the space of the whole game scene is formed. Optionally, the geometric body is a rectangular parallelepiped with the same length and width. And establishing a coordinate system XYZ in the space of the game scene, wherein the coordinate system XYZ is respectively a horizontal direction XZ coordinate and a vertical direction coordinate Y.

The virtual resources in the game scene are established on the outer surface or the inner cross section of the geometric body, for example, when the virtual scene is a building, the walls of the building are respectively arranged on the surface of the geometric body to form a closed building space. The virtual resources arranged on the geometric body can be generated by loading during game running or can be corresponding building instructions, and the corresponding virtual resources are arranged on the geometric body according to the building instructions, wherein the step of responding to the building instructions is as follows: responding to a touch operation of the user on the preset building instruction control on the graphical user interface, where the touch operation may be a click touch operation or a slide touch operation for the preset building instruction control, and the like, and is not specifically limited herein.

In an alternative embodiment, a storage device is provided, in which geometric marking information of geometric objects in a game scene is stored, and a game program can determine specific geometric objects in the game scene through the geometric marking information. In the present embodiment, when a build instruction is responded, the virtual resource type for which the build instruction is directed and the geometry-related information for carrying the virtual resource are stored.

The audio processing method provided by the embodiment comprises the following steps:

step S310, determining a path geometry according to the positions of a sound source and a sound receiving object in a game scene, wherein the path geometry is a geometry through which sound is required to be transmitted from the sound source to the sound receiving object;

step S320, judging whether virtual resources meeting preset conditions exist in the path geometry;

and step S330, setting audio processing parameters according to the judgment result.

Through the embodiment, the game space is divided into the geometric bodies which are spliced with each other, the virtual resources are established on the outer surfaces or the inner sections of the geometric bodies, so that the relevant conditions of the virtual resources on the geometric bodies can be determined by inquiring the information of the geometric bodies, after the geometric bodies which need to pass through in the process of transmitting the sound emitted by the sound source to the sound receiving object are determined according to the positions of the sound source and the sound receiving object, the virtual resources on the geometric bodies are determined to meet the preset conditions by inquiring the relevant information, and then the audio processing parameters are set according to the virtual resources.

Hereinafter, each step of the audio processing method in the present exemplary embodiment will be further described.

As shown in fig. 3, in step S310, a path geometry is determined according to the positions of the sound source and the sound receiving object in the game scene, and the path geometry is the geometry through which the sound needs to travel from the sound source to the sound receiving object.

Specifically, sound refers to sound associated with a game scene. For example, the sound related to the game scene may be a sound associated with a virtual object in the game scene, such as an engine sound of an automobile, a footstep sound of the virtual object, or a sound associated with a virtual resource in the game scene, such as a sound in a natural environment constituted by the virtual resource, such as wind sound, water sound, and the like. In this embodiment, the sound source refers to a virtual resource or a virtual object configured according to a preset rule to trigger a sound effect, where the preset rule may trigger the sound effect according to a preset action of the virtual object, for example, the preset action may be walking, running, attacking, or skill special effect of the virtual object; the preset condition may also be that the sound effect is triggered according to the preset environment of the virtual resource, for example, the preset environment may be water flow. In this embodiment, the sound receiving object is a virtual object that satisfies a preset condition with the sound source in the game scene, where the preset condition may be a preset sound propagation distance, that is, when the sound receiving object and the sound source satisfy the preset sound propagation distance, the sound receiving object is controlled to receive the sound emitted by the sound source; the preset condition may also be other parameters set by a game developer, and is not specifically limited herein.

In this embodiment, the geometric body through which the sound propagates from the sound source to the sound receiving object is a geometric body through which a connection line defined by the position information of the sound source and the position information of the sound receiving object passes, where the position information may be a specific coordinate value or a coordinate value range. Specifically, step S310 specifically includes the following steps:

step S3101, a detection step of determining a second geometric body adjacent to a first geometric body according to positions of a sound source and a sound receiving object in a game scene, wherein the first geometric body is a geometric body where the sound source is located;

step S3102, a loop is made to determine the second geometry as the first geometry for the next detection step to determine the path geometry.

Through the embodiment, the geometric bodies through which the sound passes in the propagation process can be determined according to the positions of the sound source and the sound receiving object, and then the audio processing parameters can be determined by determining the virtual resources on the geometric bodies which can pass without determining the situation of irrelevant geometric bodies, so that the calculation pressure of data can be effectively reduced.

With respect to step S3101, the detecting step determines a second geometric volume adjacent to a first geometric volume, which is the geometric volume in which the sound source is located, according to the positions of the sound source and the sound receiving object in the game scene. As shown in fig. 4, the adjacent second geometry refers to a geometry having the same face, point or edge as the first geometry. Specifically, a coordinate system is established in the game, and the positions of the virtual resources and the virtual objects in the game scene are defined through the coordinate system, for example, the coordinate value of the center point of the virtual resource or the virtual object is determined as the position of the virtual resource or the virtual object. Similarly, the position of the geometric object constituting the space of the game scene is defined by a coordinate system, for example, the geometric object is determined by three vertexes on the geometric object, and the specific geometric object can also be defined by the coordinates of the center point of the geometric object and the preset relationship between the center point and the vertex of the geometric object. And acquiring the position of a virtual object or a virtual resource as a sound source, and comparing the position of the sound source with the position of a geometric body in the game scene to determine the geometric body where the sound source is located.

It should be noted that, in the present embodiment, since the space of the game scene is formed by splicing adjacent geometric bodies, the adjacent second geometric body here is a geometric body directly adjacent to the first geometric body. In other embodiments, the adjacent second geometry may also be determined according to the division manner of the game space, and determined as a geometry that is spaced and adjacent to the first geometry, where spaced and adjacent may mean that there is another geometry between the second geometry and the first geometry, or that there is no other geometry between the second geometry and the first geometry.

Specifically, in the present embodiment, step S3101 may be implemented by:

step S31011: and updating the value of the secondary detection direction counter along with the process of determining the second geometric body, and judging whether the value of the secondary detection direction counter meets a preset value or not. The number of the second geometric bodies that the sound propagates through may be 0, that is, the same geometric body is used for the sound source and the sound receiving object, and the number of the second geometric bodies may also be multiple. When determining the second geometric body through which the sound propagates from the geometric bodies constituting the space of the game scene according to the search direction, the second geometric body is determined at a frequency of one geometric body at a time, and the value of the secondary detection direction counter is updated once every time one second geometric body is determined. In the present embodiment, the value to be updated at each time is determined by the positions of the sound source and the sound receiving object. It should be noted that the number of the secondary detection direction counters corresponds to the number of the secondary detection directions, for example, if there are two secondary detection directions, then there are two secondary detection directions.

Specifically, in the present embodiment, step S31011 may include the steps of:

step S310111: and increasing the difference corresponding to the secondary detection direction counter or initializing the current value of the secondary detection direction counter at the current value of the secondary detection direction counter along with the process of detecting the geometric body adjacent to the first geometric body in the primary detection direction and/or the secondary detection direction to obtain the updated current value. The main detection direction refers to a detection direction which is included each time when the second geometry is confirmed, and the sub detection direction refers to a detection direction which is included only when the preset condition is met when the second geometry is confirmed. The secondary detection direction counter is used to trigger the determination of the second geometry in the search direction including the secondary detection direction, and the difference value corresponding to the secondary detection direction counter is determined by the positions of the sound source and the sound receiving object. The different secondary detection direction counters have corresponding differences, and the specific determination of the differences is detailed below in step 3103. When determining the second geometry along the main detection direction or along the main detection direction and the sub-detection direction, the value of the sub-detection direction counter is updated every time the second geometry is determined, wherein the value updating method includes two types: the first is to add the current value of the secondary detection direction counter and the corresponding difference value of the secondary detection direction counter; the second clock restores the current value of the sub-detection direction counter to the initial value, for example, the initial value is "0". In this embodiment, the value updating method of the secondary detection direction counter is determined according to whether the secondary detection direction is included in the current search direction when determining the second geometric solid, specifically, when detecting the geometric solid adjacent to the first geometric solid along the main detection direction, the current value of the secondary detection direction counter is increased by the difference corresponding to the secondary detection direction counter; when detecting a geometry adjacent to the first geometry along the primary detection direction and the secondary detection direction, a current value of the secondary detection direction counter is initialized.

Step S310112: and judging whether the updated current value is greater than or equal to the maximum difference value. In this embodiment, the finding direction for determining the second geometry has at least two detection directions, including: a primary detection direction and a secondary detection direction, each of which is determined according to the positions of the sound source and the sound receiving object and has a corresponding difference value, will be described in detail in step 3103 below with respect to the relevant contents of the detection direction and the difference value, and the maximum difference value is determined as a preset value in step 31011.

Step S31012: and determining the second geometric body according to the judgment result. Specifically, the method comprises the following steps:

in step S310121, when the value of the secondary detection direction counter satisfies a preset value, a geometric body adjacent to the first geometric body is determined as a second geometric body according to the secondary detection direction and the primary detection direction. When the current value of the secondary detection direction counter is determined to be greater than or equal to the maximum difference value according to the updated current value of the secondary detection direction counter obtained in step S31011, a geometric object adjacent to the current first geometric object is determined as the second geometric object along a direction determined by both the secondary detection direction and the primary detection direction. In the present embodiment, the direction determined in common by the sub detection direction and the main detection direction means a direction corresponding to a vector determined by vector synthesis from a unit vector corresponding to the sub detection direction and a unit vector corresponding to the main detection direction, and a second geometry adjacent to the current first geometry is searched for based on the direction. In other embodiments, determining the geometry adjacent to the first geometry as the second geometry according to the secondary detection direction and the primary detection direction may be sequentially searching for the second geometry adjacent to the current first geometry according to a unit frequency along the secondary detection direction and the primary detection direction, respectively, for example, determining a transition geometry adjacent to the first geometry along the secondary detection direction, and then determining the geometry adjacent to the transition geometry as the second geometry along the primary detection direction.

Step S310122: and when the value of the secondary detection direction counter does not meet the preset value, determining the geometric body adjacent to the first geometric body as a second geometric body along the primary detection direction.

By the above embodiment, it is possible to effectively determine the second geometry adjacent to the first geometry according to the positions of the sound source and the sound receiving object without performing complicated collision detection to determine the geometry through which the sound needs to pass during propagation.

With respect to step S3102, the step is looped to determine the second geometry as the first geometry for the next detection step to determine the path geometry. In determining a geometry traversed by the sound during the propagation from the sound source to the sound receiving object, a second geometry adjacent to the first geometry is detected by loop iteration to determine the geometry traversed by the sound during the propagation, wherein the geometry is determined as the path geometry. After determining a second geometry adjacent to the current first geometry according to step S3101, the first geometry in step S3101 is executed next time with the second geometry as the first geometry. In this embodiment, before step S3102 is executed, it is determined whether or not there is a virtual resource satisfying a preset condition in the path geometry by step S320, and if there is no virtual resource satisfying the preset condition, then according to step S3102, the current second geometry is determined as the first geometry, and step S3101 is executed in a loop until it is detected that there is a virtual resource satisfying the preset condition in the path geometry, so as to stop the loop. In other embodiments, after performing the ending step S3101, execution of step S3102 is triggered until it is determined that the current first geometry coincides with the geometry in which the sound receiving object is located. In this embodiment, determining the propagation number may be implemented as follows:

step 1, determining the type of a sound source; specifically, in the present embodiment, any virtual resource or virtual object that can trigger an audio effect can be used as a sound source, where the type of the virtual resource includes, but is not limited to, a pipeline, a carrier, a gun, and the like, and the preset number of transmissions corresponding to different types of the virtual resource is preset.

Step 2, determining path geometric bodies meeting a preset number according to the positions of sound sources and sound receiving objects in a game scene, wherein the preset number corresponds to the types of the sound sources; specifically, the type of the virtual resource or the virtual object is determined by acquiring the virtual resource or the virtual object which triggers the sound effect, and the preset number of path geometries which can be propagated by the sound effect triggered by the corresponding sound source is acquired according to the type.

Further, before step S3101, step S310 further includes step S3103: and determining a primary detection direction and a secondary detection direction according to the coordinate values of the sound source and the coordinate values of the sound receiver, and distributing a corresponding secondary detection direction counter for the secondary detection direction. In the present embodiment, the number of primary detection directions is "1", the number of secondary detection directions is "2", and a coordinate system including an X axis, a Y axis, and a Z axis is established in the space of the game scene, the primary detection direction corresponding to one of the coordinate axes, and the secondary detection directions corresponding to the other two coordinate axes. In other embodiments, the primary detection direction and the secondary detection direction may correspond to different coordinate axes, and the detection direction may be defined according to actual needs.

Specifically, step S3103 includes the steps of:

step S31031: and making difference values between the axial coordinate values of the sound receiving party and the axial coordinate values of the sound source to obtain the corresponding difference values of the axial directions. In the present embodiment, coordinate values (Xs, Ys, Zs) of a sound source and coordinate values (Xr, Yr, Zr) of a sound receiving object are acquired; the coordinate values of the sound receiving objects and the coordinate values of the sound source are differentiated to obtain corresponding differences on different coordinate axes, namely diffX is Xr-Xs, diffY is Yr-Ys, and diffZ is Zr-Zs.

Step S31032: and determining that the axial direction corresponding to the maximum difference value is the main detection direction, and the other axial directions are the secondary detection directions. In this embodiment, the differences diffX, diffY, and diffZ corresponding to the coordinate axes are determined in step S31031, the coordinate axis corresponding to the largest difference is determined as the primary detection direction by the comparison, and the other coordinate values are determined as the secondary detection directions.

The above steps are illustrated below by specific illustrative examples:

as shown in fig. 5, in this example, the sound source coordinates are (0,5,5), the sound receiving object coordinates are (20,10,10), the difference value corresponding to each coordinate axis is obtained by subtracting the sound receiving object coordinates from the sound receiving object coordinates, diffX is 20, diffY is 5, and diffZ is 5, so that the maximum difference value is 20, the X axis is determined as the primary detection direction, the Y axis and the Z axis are the secondary detection directions, and corresponding counters, i.e., a Y-axis secondary detection direction counter StepY and a Z-axis secondary detection direction counter StepZ, are assigned to the secondary detection directions, and the initial values of StepY and StepZ are 0; the difference corresponding to StepY is diffY, i.e., 5, and the difference corresponding to StepZ is diffZ, i.e., 5. Determining the sound source (0,5,5) as a first geometric body, determining that the current values of StepY and StepZ are 0 and less than the maximum difference value of 20, determining the geometric body adjacent to the first geometric body as a second geometric body [ 1 ] in the main detection direction, and updating StepY and StepZ, namely, StepY +5 is 5, and StepZ +5 is 5; by judging that the current values of StepY and StepZ are both 5, the current second geometric body is taken as the first geometric body, the geometric body adjacent to the first geometric body is continuously determined as a second geometric body [ 2 ] along the main detection direction, and meanwhile, StepY and StepZ are updated, namely StepY +5 is 10, and StepZ +5 is 10; and continuing to circulate until the current values of StepY and StepZ are both determined to be 20, determining a second geometric body [ 3 ] adjacent to the first geometric body along the primary detection direction and the secondary detection direction because the current values of StepY and StepZ are 20 and equal to the maximum difference value, namely determining the second geometric body adjacent to the first geometric body along the X axis, the Y axis and the Z axis, and simultaneously updating the values of StepY and StepZ to be 0 as the initial value.

Through the embodiment, the detection direction during the process of determining the path geometry can be determined according to the sound source and the sound receiving object, the counter is distributed to each detection direction, so that the corresponding detection direction can be determined according to the numerical value of the counter, the method can determine that the sound can pass through the geometry in the sound transmission process through a small amount of calculation, and determines the virtual resource which can generate the shielding effect in the sound transmission process through detecting the virtual resource information on the geometry, and the virtual resource which needs to pass through in the sound transmission process does not need to be determined through collision detection.

With respect to step S320, it is determined whether a virtual resource satisfying a preset condition exists in the path geometry. In this embodiment, the path geometry is composed of a preset number of geometric surfaces, and determining whether a virtual resource meeting a preset condition exists in the path geometry is determining whether a virtual resource meeting a preset condition exists in at least one geometric surface in the path geometry.

In an alternative embodiment, the space of the game scene is divided into a plurality of geometric objects spliced with each other, during the initialization process of the game, the terminal loads the mark information of each geometric object and the information of the virtual resource on the geometric object, or during the detection of the running process of the game, the terminal builds the virtual resource on the outer surface or the inner cross section of the geometric object by responding to the building instruction, at this time, the terminal creates the corresponding geometric object and the associated information of the virtual resource, and the specific content is described in detail above.

In the present embodiment, when determining the virtual resource on the path geometry, the following steps may be performed:

step S3203: at least one geometric surface in the path geometry is determined from the coordinate values of the path geometry. The path geometry is composed of a plurality of geometric faces. In the present embodiment, when the path geometry is a rectangular parallelepiped, the path geometry is composed of 6 geometric surfaces. In other embodiments, since the space constituting the game scene is formed by splicing geometric objects, adjacent geometric objects share a geometric surface, and thus each path geometric object is actually composed of 3 geometric surfaces. It should be noted that the number of the geometric surfaces included in the path geometry may be set according to practical situations, and is not particularly limited herein. Since sound travels from one path geometry to another during propagation, it is only possible to traverse the geometric surface of the path geometry depending on the direction of propagation.

In this embodiment, the at least one geometric surface may be determined by:

step S32031, acquiring a first coordinate value and a second coordinate value of two adjacent geometric bodies;

step S32032 of determining a coordinate axis direction in which the corresponding axial coordinate values of the first coordinate value and the second coordinate value are different; in the present embodiment, the first coordinate value and the second coordinate value are worst, and the coordinate axis direction corresponding to the difference value whose result is not 0 is determined;

step S32033, determining geometric surfaces adjacent to each other in the coordinate axis direction in the two geometric bodies; specifically, the geometric surfaces adjacent to each other in the coordinate axis direction refer to two geometric surfaces of two geometric bodies corresponding to each coordinate axis, and planes in which the two geometric surfaces are located are adjacent to each other, where the geometric surface may be a geometric surface included in the geometric body, or may be a geometric surface shared by the geometric body and another geometric body. As shown in fig. 6, for example, assuming that the coordinate values of the adjacent a geometry and B geometry are (1,1,2) and (2,2,2), respectively, and by making a difference between the two coordinate values, it is determined that the difference value corresponding to the X axis and the Y axis is not 0, the right side geometry surface of the a geometry and the left side geometry surface of the B geometry are determined as geometry surfaces adjacent to each other on the X axis, and the upper side geometry surface of the a geometry and the lower side geometry surface of the B geometry are determined as geometry surfaces adjacent to each other on the Y coordinate axis.

Step S3204: and judging whether virtual resources meeting preset conditions exist in at least one geometric surface. In this embodiment, virtual resource information of a corresponding geometric surface on a geometric object is obtained to determine whether the virtual resource satisfies a preset condition.

Through the implementation mode, the information of the geometric surface needing to be judged can be effectively reduced, and only the virtual resource condition on the specific geometric surface needs to be acquired, so that the running speed of the game can be increased, and the game experience of a user is improved.

In the present embodiment, when determining whether there is a virtual resource satisfying a preset condition, the following steps may be performed:

s3201: acquiring the type of the virtual resource;

s3202: judging whether the type of the virtual resource meets a preset condition or not; in this embodiment, the preset condition means that the type of the virtual resource is a wall. In other embodiments, the preset condition may also refer to other types of virtual resources.

Regarding step S330, audio processing parameters are set according to the determination result.

Specifically, when the type of the virtual resource satisfies a preset condition, the audio processing parameter is set. In the present embodiment, the audio processing parameter refers to loudness of an audio effect or the like. In other embodiments, the audio processing parameter may be other audio-related parameters, and the specific parameter content for adjustment is not limited herein.

It should be noted that, the above steps may be executed simultaneously or sequentially.

Through the implementation mode, when the sound is transmitted from the sound source to the sound receiving object and the influence of the virtual resources in the game scene on the sound is determined, only the path geometric body which is possibly passed through in the sound transmission process is determined according to the preset query rule, then the virtual resource type on the path geometric body is queried in the data query mode, when the virtual resource type is the preset type, the influence of the virtual resources on the sound is determined, and then the parameters of the sound effect are set.
