[0001] The present disclosure relates to the field of audio processing technology, and in particular to an audio playback method, device, medium, electronic device and storage medium. Background Art

[0002] In game scenes, especially in game scenes with upper and lower spatial distinctions, the accuracy of sound positioning is crucial to enhancing the player's immersion and competitive experience. In related technologies, the sound can be spatialized so that the user can distinguish the left and right sources of the sound in the game scene. However, spatializing the sound does not allow the user to distinguish the source of the sound in the upper and lower spatial dimensions of the game scene. Summary of the invention

[0003] This summary is provided to introduce concepts in a brief form that will be described in detail in the detailed description below. This summary is not intended to identify key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0028] Figure 1 FIG. 1 is a flow chart of an audio playing method according to an exemplary embodiment. Figure 1 As shown, the embodiment of the present disclosure provides an audio playback method, which can be specifically performed by an audio playback device, which can be implemented by software and / or hardware and configured in an electronic device. Figure 1 As shown, the method may include the following steps.

[0029] In step 110, in response to a sound play event triggered in a virtual scene, a first position of a sound emitter corresponding to the sound play event in the virtual scene and a second position of a listener in the virtual scene are determined.

[0030] Here, the virtual scene may refer to a game scene, such as a three-dimensional game scene and a virtual reality scene, etc. The sound playback event may refer to an event triggered by a second virtual character other than the first virtual character controlled by the terminal device in the virtual scene. The second virtual character may be a player-controlled character or a non-player-controlled character. For example, the second virtual character may be a game character controlled by other players, or the second virtual character may be a monster in the virtual scene.

[0031] Of course, the sound playback event can be an event triggered by the second virtual character to instruct the playback of a specific type of sound. For example, the sound playback event can be an event triggered by the second virtual character to instruct the playback of footsteps. It should be noted that the audio resources in the game usually refer to the music, sound effects, voice and other audio in the game. The audio resources in the game are driven by the events of the game and controlled by the game parameters. For example, for shooting games, shooting is a game event and distance is a game parameter. When a character in the game performs a shooting action, the game will play the sound of the gun, and the distance will determine the hearing of the gun.

[0032] It is worth noting that, in the disclosed embodiment, all types of sound playback events can be played by the audio playback method provided by the disclosed embodiment. Of course, only specific types of sound playback events can be played by the audio playback method provided by the disclosed embodiment. For example, for a sound playback event for indicating the playback of footsteps, it can be played by the audio playback method provided by the disclosed embodiment. For a sound playback event for indicating the playback of gunshots, it may not be played by the audio playback method provided by the disclosed embodiment.

[0033] The sound emitter corresponding to the sound playback event refers to the object or event that generates sound in the virtual scene. The sound emitter can be any element in the game world as long as it can make a sound. For example, the dialogue of characters, the sound of weapons shooting, the sound of wind and rain in the environment, the sound of vehicle engines, the footsteps of virtual characters, etc. can all be considered as sound emitters.

[0034] For example, assuming that the sound playing event is triggered by the second virtual character, the sound source corresponding to the sound playing event is an object associated with the second virtual character and used to play the sound triggered by the second virtual character.

[0035] The listener refers to a character or player who receives and perceives sounds in a virtual scene. The listener corresponds to the virtual character controlled by the player, and the player perceives the sounds in the virtual scene through the listener. It should be noted that the second position of the listener is associated with the position of the virtual character controlled by the player corresponding to the listener.

[0036] The first position of the sound emitter in the virtual scene refers to the coordinate position of the sound emitter in the virtual scene. The second position of the listener in the virtual scene refers to the coordinate position of the listener in the virtual scene. In the case where the virtual scene is a three-dimensional game scene, the first position and the second position can be represented by three-dimensional coordinates.

[0037] In step 120, the hierarchical relationship between the sound source and the listener in the height direction of the virtual scene is determined according to the first position and the second position.

[0038] Here, the hierarchical relationship between the sound emitter and the listener in the height direction of the virtual scene refers to the hierarchical nature and relative height difference between different spaces of the sound emitter and the listener in the height direction of the virtual scene. Exemplarily, the hierarchical relationship may refer to the floor relationship between the sound emitter and the listener in the virtual scene. For example, the hierarchical relationship may refer to the sound emitter and the listener being on the same floor, the sound emitter being downstairs from the listener, or the sound emitter being upstairs from the listener.

[0039] Through the first position of the sound emitter and the second position of the listener, the hierarchical relationship between the sound emitter and the listener in the virtual scene can be calculated, so as to determine the audio resources emitted by the sound emitter according to different hierarchical relationships.

[0040] In step 130, a target audio resource that matches the sound playback event and is emitted by the sound emitter is determined according to the hierarchical relationship.

[0041] Here, different target audio resources correspond to different hierarchical relationships. That is, for the same sound playing event, under different hierarchical relationships, the target audio resources corresponding to the sound playing event are different.

[0042] In some embodiments, the hierarchical relationship includes a first hierarchical relationship, a second hierarchical relationship, and a third hierarchical relationship. The first hierarchical relationship indicates that the sound source and the listener are in the same height interval. The second hierarchical relationship indicates that the height interval where the sound source is located is greater than the height interval where the listener is located. The third hierarchical relationship indicates that the height interval where the sound source is located is less than the height interval where the listener is located.

[0043] The height space of the virtual scene can be divided into a plurality of different height intervals in the height direction of the virtual scene. For example, different floors can represent different height intervals. Accordingly, the first hierarchical relationship can represent that the sound emitter and the listener are on the same floor, the second hierarchical relationship can represent that the sound emitter is above the listener, and the third hierarchical relationship can represent that the sound emitter is below the listener.

[0044] Assuming that the sound playback event is an event for indicating the playback of footsteps, when the hierarchical relationship indicates that the sound emitter and the listener are on the same floor, the target audio resource emitted by the sound emitter and matching the sound playback event may be the original footsteps. When the hierarchical relationship indicates that the sound emitter is on the upper floor of the listener, the target audio resource emitted by the sound emitter and matching the sound playback event may be a first audio resource obtained by processing the original footsteps through a low-pass filter and superimposing a preset vibration sound on the processed footsteps. When the hierarchical relationship indicates that the sound emitter is on the lower floor of the listener, the target audio resource emitted by the sound emitter and matching the sound playback event may be a second audio resource obtained by processing the original footsteps through a high-pass filter and a reverb effector.

[0045] That is to say, although the sound emitters all play footsteps, the sound effects of the footsteps will be different under different hierarchical relationships.

[0046] It is worth noting that the target audio resource is determined by the hierarchical relationship. Under different hierarchical relationships, the same sound playback event will correspond to different target audio resources, so that the user can clearly distinguish the source of the sound in the height direction.

[0047] In step 140 , the target audio resource is played.

[0048] Here, the terminal device playing the target audio resource means outputting the target audio resource through the audio output hardware of the terminal device, for example, playing the target audio resource through a speaker of the terminal device or a connected headset.

[0049] Thus, by responding to the sound playback event triggered in the virtual scene, the first position of the sound source corresponding to the sound playback event in the virtual scene and the second position of the listener in the virtual scene are determined, and then the hierarchical relationship between the sound source and the listener in the height direction of the virtual scene is determined based on the first position and the second position, and the target audio resource emitted by the sound source that matches the sound playback event is determined based on the hierarchical relationship, and then the target audio resource is played. Since the same sound playback event will correspond to target audio resources with different sound effects under different hierarchical relationships, players can clearly distinguish the source of the sound in the height direction, which greatly improves the player's gaming experience. For example, in a multiplayer shooting game, for footsteps on the same floor, upstairs, and downstairs, since the sound effects of the footsteps are different, players can clearly distinguish that the footsteps come from the same floor, upstairs, or downstairs of the virtual character controlled by the player.

[0050] Figure 2 yes Figure 1 Detailed flow chart of step 120 is shown. Figure 2 As shown, in some possible implementations, step 120 may include the following steps.

[0051] In step 121, the distance between the sound source and the listener in the height direction is determined according to the first position and the second position.

[0052] Here, the distance between the sound source and the listener in the height direction of the virtual scene is calculated by the first position and the second position. For example, taking a three-dimensional game scene as an example, the first position is (X1, Y1, Z1) and the second position is (X2, Y2, Z2), then the distance between the sound source and the listener in the height direction is the absolute value of (Z1-Z2).

[0053] In step 122, a first angle between a line between the sound source and the listener and a horizontal plane is determined according to the first position and the second position.

[0054] Here, the line between the sound source and the listener is determined through the first position and the second position, and then the first angle between the line between the sound source and the listener and the horizontal plane is determined through the line between the sound source and the listener.

[0055] The horizontal plane of the virtual scene may refer to a plane in the virtual scene that is perpendicular to the direction of gravity, and the horizontal plane is a basic part of the virtual scene.

[0056] It is worth noting that the first angle has a direction and a magnitude. If the connecting line is below the horizontal plane, the first angle is negative, and if the connecting line is above the horizontal plane, the first angle is positive. Exemplarily, the value of the first angle can be [-90°, 90°].

[0057] In step 123, the hierarchical relationship is determined according to the distance and the first angle.

[0058] Here, after the distance and the first angle are determined, the hierarchical relationship between the sound source and the listener is determined by the distance and the first angle.

[0059] It should be noted that the direction of the sound source relative to the listener can be clearly distinguished by the first angle between the line between the sound source and the listener and the horizontal plane. For example, the first angle can be used to distinguish whether the sound source is below or above the listener. The height distance between the sound source and the listener can be used to clearly distinguish whether the sound source and the listener are in the same height range.

[0060] Following the above embodiment, when the distance is less than or equal to a preset distance threshold or the first angle is within a preset angle range, the hierarchical relationship is determined to be a first hierarchical relationship.

[0061] The preset distance threshold may be a distance threshold used to characterize that the sound source and the listener are in the same height range. Exemplarily, the preset distance threshold may be 300 cm. Of course, the preset distance threshold may be set according to actual conditions. For example, the preset distance threshold is determined according to the floor height of the building in the virtual scene. Exemplarily, if the floor height of the building in the virtual scene is 400 cm, the preset distance threshold may be 400 cm.

[0062] The preset angle range may be an angle range used to characterize that the sound source and the listener are in the same height range. Exemplarily, the preset angle range may be [-45°, 45°]. Of course, the preset angle range may also be set according to actual conditions. For example, the preset angle range may be determined according to the floor height of the building in the virtual scene. Exemplarily, the greater the floor height of the building in the virtual scene, the greater the upper limit of the preset angle range may be and the smaller the lower limit of the preset angle range may be. For example, the preset angle range may be [-60°, 60°].

[0063] When the distance between the sound source and the listener in the height direction is less than or equal to the preset distance threshold, it means that the sound source and the listener are in the same height interval. When the first angle is within the preset angle range, it means that the sound source and the listener are in the same height interval.

[0064] When the distance is greater than a preset distance threshold and the first angle is greater than an upper limit of a preset angle range, the hierarchical relationship is determined to be a second hierarchical relationship.

[0065] When the distance between the sound source and the listener in the height direction is greater than the preset distance threshold, it means that the sound source and the listener are in different height intervals. Under the premise that the distance is greater than the preset distance threshold, if the first angle is greater than the upper limit of the preset angle range, it means that the sound source is located above the listener, that is, the height interval where the sound source is located is greater than the height interval where the listener is located. Therefore, the hierarchical relationship between the sound source and the listener is a second-level relationship.

[0066] When the distance is less than the second distance threshold and the first angle is less than the lower limit of the preset angle range, it is determined that the hierarchical relationship is a third hierarchical relationship.

[0067] When the distance between the sound source and the listener in the height direction is greater than the preset distance threshold, it means that the sound source and the listener are in different height intervals. Under the premise that the distance is greater than the preset distance threshold, if the first angle is less than the lower limit of the preset angle range, it means that the sound source is located below the listener, and the height interval where the sound source is located is less than the height interval where the listener is located. Therefore, the hierarchical relationship between the sound source and the listener is a third-level relationship.

[0068] It can be seen that through the distance and the first angle, the different hierarchical relationships between the sound emitter and the listener can be clearly distinguished in the virtual scene, so that the target audio resources played by the same type of sound playback event in different hierarchical relationships are different.

[0069] Figure 3 is a schematic diagram of a virtual scene according to an exemplary embodiment. Figure 3 As shown, in the virtual scene 200, assuming that the listener 201 corresponding to the first virtual character controlled by the electronic device is 310 cm away from the first sound source 202 used to play the footsteps of the second virtual character in the height direction, and the first angle between the listener 201 and the first sound source 202 is 46°, the hierarchical relationship between the first sound source 202 and the listener 201 is a second hierarchical relationship.

[0070] Assuming that the distance in height direction between the listener 201 corresponding to the first virtual character controlled by the electronic device and the second sound-emitting body 203 used to play the footsteps of the third virtual character is 390 cm, and the first angle between the listener 201 and the second sound-emitting body 203 is -70°, the hierarchical relationship between the second sound-emitting body 203 and the listener 201 is a third-level relationship.

[0071] It is worth mentioning that Figure 3 The second position of the listener 201 in the embodiment is only used as an example to illustrate the embodiment of the present disclosure, and does not mean that in a specific implementation, the second position of the listener 201 can only be as follows. Figure 3 As shown, the specific setting method of the listener 201 in the virtual scene can be set according to actual conditions.

[0072] It should be noted that, for other extreme cases, the type of the sound playback event can be used to determine whether to use the audio playback method provided by the embodiment of the present disclosure to process the sound playback event. Of course, it is also possible to determine whether to use the audio playback method provided by the embodiment of the present disclosure to process the sound playback event by setting preset distance thresholds of different sizes for different types of sound playback events.

[0073] like Figure 3 As shown, it is assumed that the distance in the height direction between the listener 201 corresponding to the first virtual character controlled by the electronic device and the third sound-emitting body 204 for playing the footsteps of the fourth virtual character is 150 cm, and the first angle between the listener 201 and the second sound-emitting body 203 is -46°. At this time, the fourth virtual character is on the same floor as the third virtual character, but the fourth virtual character is located on the box, resulting in the distance between the listener 201 and the third sound-emitting body 204 being smaller than the distance between the listener 201 and the second sound-emitting body 203. Since the fourth virtual character and the third virtual character are in contact with different media, the type of footsteps will not be different, so the type of sound playback event will also be different. Therefore, the preset distance threshold corresponding to the sound-emitting body for emitting footsteps located on the box can be set smaller, so that the hierarchical relationship between the third sound-emitting body 204 and the listener 201 can also be determined as a third-level relationship.

[0074] Therefore, through the distance and the first angle, the different hierarchical relationships between the sound source and the listener can be clearly distinguished in the virtual scene, so that the target audio resources played by the same type of sound playback event in different hierarchical relationships are different.

[0075] In some feasible implementations, in step 130, when the hierarchical relationship is a first hierarchical relationship, the original audio resource corresponding to the sound playing event is determined as the target audio resource.

[0076] Here, for a detailed description of the first hierarchical relationship, please refer to the relevant description of the above implementation method, which will not be repeated here. When the hierarchical relationship between the sound source and the listener is a first hierarchical relationship, it means that the sound source and the listener are on the same floor. At this time, the original audio resource corresponding to the sound playback event can be determined as the target audio resource.

[0077] It should be understood that the original audio resource corresponding to the sound play event may refer to a stereo audio resource produced for the sound play event, and the original audio resource may be understood as a basic audio resource. Taking the sound play event as an event for indicating the play of footsteps as an example, the original audio resource is the original footsteps pre-produced by the game developer.

[0078] That is to say, when the hierarchical relationship is the first hierarchical relationship, the sound source plays the original audio resource.

[0079] In some feasible implementations, in step 130, when the hierarchical relationship is the second hierarchical relationship, the first audio resource is determined as the target audio resource, and the first audio resource is obtained by processing the original audio resource through a low-pass filter.

[0080] Here, for a detailed description of the second hierarchical relationship, reference may be made to the relevant description of the above implementation manner, which will not be repeated here. When the hierarchical relationship between the sound source and the listener is a second hierarchical relationship, it means that the sound source and the listener are on different floors, and the sound source is located above the listener. At this time, the first audio resource can be determined as the target audio resource.

[0081] The first audio resource is obtained by processing the original audio resource through a low-pass filter. It should be noted that the parameters of the low-pass filter can be set according to actual conditions.

[0082] In some embodiments, when the original audio resource is footsteps, the first audio resource is obtained by processing the original footsteps through a low-pass filter and superimposing a preset vibration sound on the processed footsteps.

[0083] For example, the preset vibration sound may be an audio resource representing floor vibration. By processing the original footsteps through a low-pass filter and superimposing the audio resource representing floor vibration on the low-pass filtered footsteps, the first audio resource can accurately simulate the footsteps coming from the upper floor.

[0084] In some feasible implementations, in step 130, when the hierarchical relationship is a third hierarchical relationship, a second audio resource is determined as a target audio resource, and the second audio resource is obtained by processing the original audio resource through a high-pass filter and a reverberation effector.

[0085] Here, for a detailed description of the third hierarchical relationship, please refer to the relevant description of the above implementation method, which will not be repeated here. When the hierarchical relationship between the sound source and the listener is the third hierarchical relationship, it means that the sound source and the listener are on different floors, and the sound source is located downstairs from the listener. At this time, the second audio resource can be determined as the target audio resource.

[0086] The second audio resource is obtained by processing the original audio resource through a high-pass filter and a reverb effector. That is, the second audio resource is obtained by adding a high-pass filter and a reverb effector to the original audio resource. It should be noted that the parameters of the high-pass filter and the reverb effector can be set according to actual conditions.

[0087] It is worth noting that the original audio resource, the first audio resource and the second audio resource can all be pre-made audio resources. Of course, in other implementations, the original audio resource can be a pre-made audio resource, and the first audio resource and the second audio resource can be made in real time based on the original audio resource.

[0088] Therefore, under different hierarchical relationships, the sound effects of the target audio resources corresponding to the same type of sound playback event are different, so that players can clearly distinguish the source of the sound in the height direction through hearing, greatly improving the player's gaming experience.

[0089] In some achievable implementations, after step 130, the volume and / or reverberation effect of the target audio resource is adjusted according to the second angle between the orientation of the virtual character corresponding to the listener and the horizontal plane to obtain an adjusted target audio resource. Accordingly, in step 140, the adjusted target audio resource can be played.

[0090] Here, the orientation of the virtual character may refer to the direction the virtual character faces or the main orientation of the body in the virtual scene. Since the listener is associated with the virtual character controlled by the player, and the virtual character has an orientation in the virtual scene, the sound effect of the target audio resource may be different when the orientation is different.

[0091] The second angle has a direction and a magnitude. If the connecting line is below the horizontal plane, the second angle is negative, and if the connecting line is above the horizontal plane, the second angle is positive. Exemplarily, the value of the second angle can be [-90°, 90°].

[0092] For second angles of different sizes, the volume and / or reverberation effect of the target audio resource may be adjusted to different degrees to obtain the adjusted target audio resource.

[0093] As some examples, when the second angle is greater than the first angle threshold, the volume of the target audio resource is increased and the reverberation effect of the target audio resource is reduced.

[0094] The first angle threshold may be 45°, and of course, the first angle threshold may also be set according to actual conditions. The second angle being greater than the first angle threshold actually indicates that the virtual character corresponding to the listener is facing a higher height interval, for example, the virtual character corresponding to the listener is facing upstairs.

[0095] When the second angle is greater than the first angle threshold, by increasing the volume of the target audio resource and reducing the reverberation effect of the target audio resource, the volume of the target audio resource that the player can hear can be louder and the reverberation effect can be lower.

[0096] As some further examples, when the second angle is less than a second angle threshold, the volume of the target audio resource is increased and the reverberation effect of the target audio resource is reduced.

[0097] The second angle threshold may be -45°, and of course, the second angle threshold may also be set according to actual conditions. The second angle being greater than the second angle threshold actually indicates that the virtual character corresponding to the listener is facing a lower height interval, for example, the virtual character corresponding to the listener is facing downstairs.

[0098] When the second angle is smaller than the second angle threshold, by increasing the volume of the target audio resource and reducing the reverberation effect of the target audio resource, the volume of the target audio resource that the player can hear can be louder and the reverberation effect can be lower.

[0099] That is to say, for the footsteps coming from downstairs and upstairs, when the virtual character corresponding to the listener faces different directions, the player will hear different footsteps coming from downstairs and upstairs. When the virtual character faces upstairs, the footsteps coming from upstairs are louder and have lower reverberation effect than those coming from downstairs. When the virtual character faces downstairs, the footsteps coming from downstairs are louder and have lower reverberation effect than those coming from upstairs.

[0100] Therefore, by adjusting the volume and / or reverberation effect of the target audio resource according to different directions, the played target audio resource can be made to meet the direction requirements of the virtual character, making the game more realistic.

[0101] In some feasible implementations, in step 140, based on the first position and the second position, the target audio resource is spatialized, and the spatialized target audio resource is played; and when the virtual character corresponding to the listener triggers the playing of an audio resource of the same type as the target audio resource, the audio resource is played directly.

[0102] Here, in the game, the first virtual character controlled by the electronic device and the second virtual character in the virtual scene usually use the same set of audio resources. For example, for footsteps, the footsteps triggered by the first virtual character and the second virtual character are all from the same set of footsteps resources. Therefore, if the same set of audio resources is used to play the same type of audio triggered by the first virtual character and the second virtual character, the player will not be able to distinguish whether the sound is generated by the first virtual character or the second virtual character.

[0103] In this regard, the target audio resource can be spatialized based on the first position and the second position, and the target audio resource after spatialization can be played. It should be noted that in the embodiments of the present disclosure, no specific limitation is made to spatialization. Spatialization is essentially to simulate the propagation of sound based on the relative position between the sound source and the listener using a sound propagation model, so that the target audio resource after spatialization can be more natural and realistic, or create a specific spatial atmosphere.

[0104] When the virtual character corresponding to the listener triggers the playback of an audio resource of the same type as the target audio resource, the audio resource is not spatialized and the stereo audio resource is played directly.

[0105] Of course, in other implementations, the volume of the target audio resource after spatialization processing may be further reduced to further distinguish the target audio resource triggered by the second virtual character from the audio resource of the same type as the target audio resource triggered by the first virtual character in terms of volume.

[0106] It is worth noting that, following the above implementation, the target audio resource may be an adjusted target audio resource obtained by adjusting the volume and / or reverberation effect of the target audio resource.

[0107] Therefore, through the above-mentioned implementation, even if the first virtual character and the second virtual character use the same audio resource, when the target audio resource triggered by the second virtual character and the audio resource of the same type as the target audio resource triggered by the first virtual character are played at the same time, the player can hear obvious differences in volume, sound image and timbre, thereby facilitating the player to distinguish between the sound triggered by the player himself and the sound triggered by other characters.

[0108] In some feasible implementations, in step 140, an occlusion coefficient corresponding to an obstacle between the sound-emitting body and the listener is determined, and then, when the obstacle includes a virtual object for distinguishing different hierarchical relationships in the height direction, the occlusion coefficient of the virtual object is reduced to obtain an adjusted occlusion coefficient, and based on the adjusted occlusion coefficient, sound occlusion processing is performed on the target audio resource to obtain the target audio resource after occlusion processing, and then the target audio resource after occlusion processing is played.

[0109] Here, in real scenes, the direct sound after the sound is emitted and the reflected sound after multiple reflections are heard by the human ear after a period of time. If there is an obstacle between the sound source and the human ear, the sound will bypass (diffraction) or pass through (transmission) the obstacle, thus forming different sound effects.

[0110] The obstacle between the sound source and the listener may refer to an obstacle on the propagation path between the sound source and the listener. The occlusion coefficient of an obstacle is a parameter used to quantify the effect of an obstacle on sound propagation. The occlusion coefficient indicates the degree to which the sound is attenuated when passing through the obstacle. The value of the occlusion coefficient is usually between 0 and 1. The larger the value, the stronger the occlusion effect of the obstacle on the sound.

[0111] The virtual objects used to distinguish different hierarchical relationships in the height direction are floors and roofs set in the virtual scene. When the sound propagation path between the sound source and the listener includes the virtual objects used to distinguish different hierarchical relationships in the height direction, the occlusion coefficient of the virtual objects is reduced to obtain the adjusted occlusion coefficient.

[0112] That is to say, in the virtual scene, the occlusion coefficient of the roof and the floor will be smaller than the occlusion coefficient of the wall, so that the sounds from upstairs and downstairs can more easily penetrate the roof and the floor and be heard by the first virtual character.

[0113] Sound occlusion processing refers to the process of adjusting and processing the sound signal of the target audio resource according to the impact of obstacles on the sound propagation during the sound propagation process. Obstacles can be walls, buildings, furniture, terrain, etc., which will block or weaken the propagation of sound and change the sound when it reaches the listener.

[0114] By performing sound occlusion processing on the target audio resource through the adjusted occlusion coefficient, the sound emitted from upstairs and downstairs can be more easily penetrated by the roof and the floor, so as to be heard by the first virtual character.

[0115] It is worth noting that, following the above implementation, the target audio resource may be a target audio resource after spatialization processing.

[0116] Therefore, through the above implementation, the sounds emitted from upstairs and downstairs in the virtual scene can more easily penetrate the roof and the floor, and thus be heard by the players.

[0117] In some feasible implementations, in step 140 , the audio format of the target audio resource may be converted into an object-based audio format, and the target audio resource in the object-based audio format may be played.

[0118] Here, the audio format is the carrier of the sound after digitization. Different audio formats have different abilities to record sound. For the stereo audio format, only the sound in the 180° plane in front of the user can be recorded. Sound outside this range will be compressed into this area.

[0119] For a sound of the target audio resource type, the audio format of the target audio resource may be converted to an object-based audio format so that the target audio resource may be played using the object-based audio format.

[0120] Among them, the object-based audio format allows audio content to be divided into multiple independent audio objects or entities, each object can contain different audio elements.

[0121] By playing the target audio resource in the object-based audio format, the sounds from different hierarchical relationships can be played from different height spaces, so that players can more accurately locate the source of the sound. For example, playing the footsteps in the object-based audio format can make the footsteps coming from upstairs or downstairs be played from the upper space of the upstairs or the lower space of the downstairs.

[0122] Of course, other types of audio resources can be played using the Ambisonics audio format. Ambisonics is an audio technology that can capture and reproduce the position and directionality of sound in three-dimensional space. Because Ambisonics simulates the way sound propagates in the real world, including the direction, distance, reflection, and reverberation of sound, Ambisonics makes the audio experience more immersive and realistic.

[0123] It is worth noting that, following the above implementation, the target audio resource may be a target audio resource after spatialization processing. Of course, the target audio resource may also be a target audio resource after occlusion processing.

[0124] Therefore, by converting the audio format of the target audio resource into an object-based audio format, sounds from different hierarchical relationships can be truly played from different height spaces, allowing players to more accurately locate the source of the sound in the height direction.

[0125] In some feasible implementations, in step 140, sound rendering parameters matching the device type can be determined according to the device type to which the electronic device belongs, and based on the sound rendering parameters, the target audio resource can be rendered and the rendered target audio resource can be played.

[0126] Here, sound rendering is the last step in the audio processing flow. Sound rendering adjusts and optimizes the decoded audio data according to specific sound rendering parameters. Among them, sound rendering parameters can include volume, timbre, sound effects and other parameters. Sound rendering parameters determine the final performance of the sound in the speaker. Through sound rendering, audio data is converted into an analog signal suitable for speaker playback. This analog signal can drive the speaker's diaphragm to vibrate, thereby generating sound.

[0127] The device type of the electronic device can be determined by the system version and model of the electronic device. Different sound rendering parameters can be corresponding to electronic devices of different device types.

[0128] Exemplarily, a mapping relationship between different device types and different rendering options may be preconfigured, wherein each rendering option includes a sound rendering parameter that matches the device type.

[0129] After determining that the sound rendering parameters matching the device type are obtained, the target audio resource is rendered using the sound rendering parameters to obtain the rendered target audio resource, and the rendered target audio resource is played.

[0130] It should be understood that if the game does not have a sound rendering parameter that matches the device type, the player can be prompted to enable the corresponding system permissions. If the player does not enable the corresponding system permissions, the preset sound rendering parameters can be used to render the target audio resources to provide a comprehensive spatial positioning experience.

[0131] It is worth noting that since different types of electronic devices use different sound playback technologies, it is difficult for users to understand the difference between different playback technologies. In order for electronic devices to better utilize the characteristics of the system and hardware and render the best sound effects, the target audio resources are rendered using sound rendering parameters that match the device type. The audio resources in the virtual scene can adaptively match electronic devices of different device types to play the target audio resources, thereby achieving the best effect.

[0132] It should be noted that, following the above implementation, the target audio resource may be a target audio resource after spatialization processing, of course, the target audio resource may also be a target audio resource after occlusion processing, or the target audio resource may be a target audio resource in an object-based audio format after format conversion.

[0133] Therefore, through the above implementation, the playback of the target audio resource can be adaptively adapted to electronic devices of different device types, so that the sound effect of the target audio resource can be optimized.

[0134] Below, combined with the attached Figure 4 The above-mentioned embodiment will be described in detail.

[0135] Figure 4 FIG. 1 is a flowchart of an audio playback method according to another exemplary embodiment. Figure 4 As shown, in response to a sound playback event triggered in a virtual scene, a first position of a sound source corresponding to the sound playback event in the virtual scene and a second position of a listener in the virtual scene are determined, and then, based on the first position and the second position, a hierarchical relationship between the sound source and the listener in the height direction of the virtual scene is determined, and then, based on the hierarchical relationship, a target audio resource emitted by the sound source and matching the sound playback event is determined.

[0136] After the target audio resource is determined, the target audio resource may be spatially processed based on the first position and the second position to obtain the target audio resource after spatial processing.

[0137] After obtaining the target audio resource after spatialization processing, sound occlusion processing may be performed on the target audio resource after spatialization processing to obtain the target audio resource after occlusion processing.

[0138] After obtaining the target audio resource after occlusion processing, the audio format of the target audio resource after occlusion processing may be converted into an object-based audio format.

[0139] Finally, the target audio resource in the object-based audio format is rendered using the sound rendering parameters that match the device type, and the rendered target audio resource is played.

[0140] It is worth noting that under different hierarchical relationships, the same sound playback event corresponds to different target audio resources. Then, combined with spatial processing, sound occlusion processing, audio format conversion and sound rendering, it can ensure that players can clearly distinguish the source of the sound in the height direction in multiple processes of sound playback, greatly improving the player's gaming experience.
