[0034] Figure 1 This is a flow chart of an audio processing method provided in an embodiment of the present disclosure. The embodiment of the present disclosure is applicable to the situation where the audio data of each microphone position is adjusted when a live broadcast room is connected to the microphone. The method can be executed by an audio processing device, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by configuring on any electronic device with network communication function, which can be a mobile terminal, PC or server, etc.

[0035] like Figure 1 As shown, the audio processing method in this embodiment may include but is not limited to the following processes:

[0036] S110. Detect a target sound source position of target audio data, where the target audio data is audio data associated with a target microphone position in the live broadcast room. The target sound source position is used to describe the sound position when a target sound source object emits a sound corresponding to the target audio data. The target sound source object is a sound source object corresponding to the target microphone position.

[0037] The channels of the host and guests in the live broadcast room are usually mono, so that the sound volume heard by the headphones on both sides is balanced. In the live broadcast room microphone connection scenario, the audio data of the microphone in the live broadcast room has a low sense of hearing and immersion in the audio experience, which may cause many problems such as audio flattening and lack of authenticity, audio confusion after sound fusion in multi-person connection scenarios, and inability to distinguish the ownership of sounds. For this reason, it is necessary to adjust the audio data of the microphone in the live broadcast room to improve the sense of hearing and immersion of the audio experience after the adjustment.

[0038] The live broadcast room may include at least one microphone. Different users can interact with each other remotely through multiple microphones in the same live broadcast room. Each user can input audio on the device corresponding to the microphone he / she uses, and the input audio can be shared through the microphones in the live broadcast room during the interactive session.

[0039] For the target microphone position in the live broadcast room, audio data associated with the target microphone position can be obtained by audio collection at the device end corresponding to the target microphone position, which is recorded as the target audio data. At the same time, the target audio data can be the audio data formed when the sound source object corresponding to the target microphone position emits sound at the device end corresponding to the target microphone position, and the sound position when the sound source object corresponding to the target microphone position emits the sound corresponding to the target audio data can be used as the target sound source position of the target audio data.

[0040] S120. Determine a target spatial audio coordinate corresponding to a target microphone position according to a target sound source position, where the spatial audio coordinate is used to simulate a three-dimensional spatial sound effect.

[0041] In order to further optimize the immersiveness of the audio and allow the audio corresponding to the connected microphone in the live broadcast room to jump out of the microphone position limit, this case no longer solidifies the audio of the live broadcast room and the microphone position. For the audio data emitted from different positions corresponding to the target microphone position, the target audio source position corresponding to the target audio data is dynamically adapted to the target microphone position through the target audio source position. In this way, it can be achieved that when the sound source position of the audio data corresponding to the target microphone position is different, the spatial audio coordinates corresponding to the target microphone position are different, and then it can be ensured that the same target microphone position uses different three-dimensional spatial sound effect simulation results as the sound source position of its corresponding audio data is different.

[0042] S130: Use the target spatial audio coordinates to adjust and output the target audio data corresponding to the target microphone position.

[0043] For the target audio data of the target microphone in the live broadcast room, the function of the target spatial audio coordinates to simulate the three-dimensional spatial sound effect can be used to adjust the audio effect of the target audio data of the target microphone in real time, so that the target audio data of the target microphone in the live broadcast room can be dynamically adjusted following the changes in the sound position of the target audio data of the target microphone, and then the adjusted audio data is output, so that the audio effect of the target audio data is more in line with the actual picture perception when the audio is output, and the audio listening experience and immersion are improved, and the problem of low listening experience and immersion of the audio experience in the live broadcast and microphone connection scene is solved, and it is ensured as much as possible that the audience has a clearer sense of direction when listening to the sound of each microphone, so as to achieve a better dynamic spatial audio effect.

[0044] Optionally, different spatial audio coordinates are associated with different spatial audio parameters, and the audio effect of the same target audio data is adjusted by using different spatial audio parameters, so that the same target audio data can have different spatial audio effects, that is, different three-dimensional stereoscopic spatial sound effects are simulated. Optionally, the target audio data is adjusted using the target spatial audio coordinates, and the audio is output through the target microphone position in the live broadcast room according to the adjusted audio data.

[0045] As an optional but non-limiting implementation, adjusting the target audio data corresponding to the target microphone position by using the target spatial audio coordinates may include steps A1-A2:

[0046] Step A1: Based on the target spatial audio coordinates corresponding to the target microphone position, the original spatial audio coordinates used by the target microphone position are adjusted and updated.

[0047] Step A2: adjusting the target audio data using the spatial audio coordinates used by the adjusted and updated target microphone position.

[0048] For the microphone positions in the live broadcast room, each microphone position corresponds to a preset spatial audio coordinate adjustment interface. By calling the preset spatial audio coordinate adjustment interface, the original spatial audio coordinates used by the target microphone position are adjusted in real time and dynamically to ensure that the spatial audio coordinates to be used by the microphone position can be adjusted as the sound source position of the audio data corresponding to the microphone position changes, that is, it is adjusted as the corresponding sound position changes when the audio data is emitted.

[0049] After updating and adjusting the spatial audio coordinates to be used by the target microphone, the updated spatial audio coordinates can be used to make real-time adjustments to the audio effect of the target audio data of the target microphone, so that the target audio data of the target microphone in the live broadcast room can be dynamically adjusted as the sound position of the target audio data of the target microphone changes.

[0050] Optionally, when the target sound source position of the target audio data is detected and no target spatial audio coordinates corresponding to the target microphone position are obtained, default spatial audio coordinates pre-associated with the target microphone position may be used as the target spatial audio coordinates corresponding to the target microphone position.

[0051] The technical solution of the disclosed embodiment detects the sound source position corresponding to the target audio data of the target microphone in the live broadcast room, and matches the target microphone with suitable target spatial audio coordinates based on the detected sound source position of the target audio data of the target microphone. The target spatial audio coordinates can simulate the three-dimensional spatial sound effect to adjust the target audio data of the target microphone in real time, so that the target audio data of the target microphone in the live broadcast room has a spatial audio effect, thereby solving the problem of low listening sense and immersion of the audio experience in the live broadcast and microphone connection scene, and ensuring as much as possible that the audience has a clearer sense of direction when listening to the sound of each microphone from the perspective of the audience, thereby achieving a better dynamic spatial audio effect.

[0052] Figure 2 The present disclosure provides a flowchart of another audio processing method. The technical solution of this embodiment further optimizes the process of detecting the target sound source position of the target audio data in the above embodiment on the basis of the above embodiment. This embodiment can be combined with various optional solutions in one or more of the above embodiments. Figure 2 As shown, the audio processing method of this embodiment may include the following process:

[0053] S210, determining the target part position of the target sound source object corresponding to the target audio data, where the target part position is the position of the target part of the target sound source object in the target picture, and the target picture is the image picture of the target sound source object corresponding to the sound corresponding to the target audio data when the target sound source object emits.

[0054] Among them, the target audio data is the audio data associated with the target microphone position in the live broadcast room, the target sound source position is used to describe the sound position when the target sound source object emits the sound corresponding to the target audio data, and the target sound source object is the sound source object corresponding to the target microphone position.

[0055] When the target sound source object emits a sound corresponding to the target audio data, an image screen including the target sound source object may be obtained as a target screen.

[0056] S220, determining the target sound source position of the target audio data according to the target part position.

[0057] Optionally, for the target part of the target sound source object, the position distribution of the sound part of the target sound source object on the entire target part (the sound part may be a part of the target part, and the target part includes the sound part) can be pre-stored. Combined with the position distribution of the sound part on the entire target part and the position of the target part, the position of the sound part of the target sound source object can be roughly estimated, and the estimated position of the sound part can be used as the target sound source position of the target audio data.

[0058] As an optional but non-limiting implementation, determining the target sound source position of the target audio data according to the target part position may include steps B1-B3:

[0059] Step B1, determining a target part image from a target picture according to the position of the target part.

[0060] Step B2: determining a center position of a reference side boundary of the target part image, where the reference side boundary is a preset side boundary of the target part image.

[0061] Step B3: determine the target sound source position of the target audio data based on the reference side boundary center position.

[0062] When the live broadcast room is connected to the microphone for interaction, the sound source objects corresponding to each microphone position are not fixed. That is, the sound source object may do some operations such as tilting the head when speaking, resulting in the determined target part positions being the position coordinates corresponding to the tilt of the head, rather than the target part positions determined from directly in front of the target part. As a result, the position of the sound part determined based on the target part position may be biased, which in turn causes the subsequent acquisition of erroneous spatial audio coordinates.

[0063] To this end, based on the position of the target part of the target sound source object in the target picture, a target part image that includes the entire target part of the target sound source object can be determined from the target picture. Furthermore, the lower side boundary of the target part image can be taken as the reference side boundary, and the center position of the reference side boundary can be taken as the position of the sound source part of the target sound source object, and the estimated position of the sound source part can be taken as the target sound source position of the target audio data.

[0064] S230. Determine the target spatial audio coordinates corresponding to the target microphone position according to the target sound source position, where the spatial audio coordinates are used to simulate a three-dimensional spatial sound effect.

[0065] As an optional but non-limiting implementation, determining the target spatial audio coordinates corresponding to the target microphone position according to the target sound source position may include steps C1-C2:

[0066] Step C1, determine the target relative position information of the target sound source position relative to the center of the target picture, the target relative position information includes the distance and / or angle from the target sound source position to the center of the target picture, and the target picture is an image picture obtained by capturing the target sound source object when the target sound source object emits a sound corresponding to the target audio data.

[0067] Step C2: determining the target spatial audio coordinates corresponding to the target microphone position according to the target relative position information, and the target spatial audio coordinates change with the adjustment of the target relative position.

[0068] According to the actual multi-person communication scenario, the audio generated at different positions has a certain correlation. If the target sound source position is detected and directly converted into the target spatial audio coordinates, the audio data of each microphone position will be greatly different from the actual multi-person scenario due to the lack of reference between the target sound source positions.

[0069] To this end, the target relative position information of the target sound source position relative to the target picture center can be calculated. The target relative position information includes the distance and / or angle from the target sound source position to the target picture center. The calculated target relative position information is then used to calculate the final spatial audio coordinates. In this way, different and relative spatial audio coordinates can be assigned based on the relative situation of the sound source position to the center of the picture, which is more in line with the relative position of each sound source object in an actual multi-person scene.

[0070] As an optional but non-limiting implementation, determining the target spatial audio coordinates corresponding to the target microphone position according to the target sound source position may include steps D1-D3:

[0071] Step D1, determining a target position difference of the target audio data, where the target position difference is determined based on a position difference between a target sound source position obtained by a current target sound source position detection operation and a target sound source position obtained by a previous target sound source position detection operation.

[0072] Step D2: If the target position difference does not meet the preset difference confidence condition, the target spatial audio coordinates corresponding to the target microphone position are determined according to the target sound source position.

[0073] Step D3: If the target position difference satisfies a preset difference confidence condition, the spatial audio coordinates originally used by the target audio data are determined as the target spatial audio coordinates corresponding to the target microphone position.

[0074] Each time the target spatial audio coordinates corresponding to the target microphone position are detected, not every detected spatial audio coordinates are very different from the previous detection. If the new target spatial audio coordinates are used to adjust the target audio data when the difference is not big, it will be found that the audio effect after adjusting the audio data using the two target spatial audio parameters will not change significantly. In other words, it is acceptable to use the original target spatial audio coordinates.

[0075] However, when the difference is not big, if you use the new target spatial audio coordinates and call the preset spatial audio adjustment interface or use the preset spatial audio adjustment information stream to reset the spatial audio coordinates to be used by the target microphone position, there will be a considerable setup overhead. It can be seen that frequently calling the interface to update the spatial audio coordinates will cause a large performance overhead.

[0076] To this end, this case sets a preset difference confidence condition, which is based on the target position difference between the target sound source position obtained by the current target sound source position detection operation and the target sound source position obtained by the previous adjacent target sound source position detection operation, so as to use the target position difference to detect whether the same or similar sound effects are produced after the two spatial audio coordinates are adjusted for the same audio data.

[0077] If the target position difference is greater than or equal to the confidence λ corresponding to the preset difference confidence condition, it means that the sound effects that can be produced by the current target spatial audio coordinates and the previous target spatial audio coordinates for the same audio data have changed significantly. At this time, the target spatial audio coordinates corresponding to the target microphone position can be determined based on the target sound source position, and the spatial audio parameters to be used by the target microphone position can be reconfigured.

[0078] If the target position difference is less than the confidence λ corresponding to the preset difference confidence condition, it means that the sound effect change that can be produced by the current target spatial audio coordinates and the previous target spatial audio coordinates for the same audio data is not very obvious. Even if the interface is called to change the spatial audio coordinates, the actual effect cannot be clearly distinguished from the audience's hearing, which is an invalid change. Therefore, this spatial audio change is discarded and the spatial audio coordinates originally used by the target audio data remain unchanged.

[0079] By adopting the above method, it is possible to determine whether it is necessary to reconfigure the spatial audio coordinates used by the target microphone position based on whether the audio effect change after the audio data adjustment is obvious according to the two target spatial audio parameters obtained from the two previous and subsequent detections, thereby reducing performance overhead.

[0080] S240: Use the target spatial audio coordinates to adjust and output the target audio data corresponding to the target microphone position.

[0081] The technical solution of the disclosed embodiment detects the sound source position corresponding to the target audio data of the target microphone in the live broadcast room, and matches the target microphone with suitable target spatial audio coordinates based on the detected sound source position of the target audio data of the target microphone. The target spatial audio coordinates can simulate the three-dimensional spatial sound effect to adjust the target audio data of the target microphone in real time, so that the target audio data of the target microphone in the live broadcast room has a spatial audio effect, thereby solving the problem of low listening sense and immersion of the audio experience in the live broadcast and microphone connection scene, and ensuring as much as possible that the audience has a clearer sense of direction when listening to the sound of each microphone from the perspective of the audience, thereby achieving a better dynamic spatial audio effect.

[0082] Figure 3The present disclosure provides another flow chart of an audio processing method. The technical solution of this embodiment further optimizes the process of detecting the target sound source position of the target audio data in the above embodiment. This embodiment can be combined with various optional solutions in one or more of the above embodiments. Figure 3 As shown, the audio processing method of this embodiment may include the following process:

[0083] S310: Determine a reference detection time interval used when performing a target sound source position detection operation.

[0084] S320, detecting the target sound source position of the target audio data according to a reference detection time interval, where the reference detection time interval is used to make the time interval between two adjacent target sound source position detection operations greater than a preset time length.

[0085] Among them, the target audio data is the audio data associated with the target microphone position in the live broadcast room, the target sound source position is used to describe the sound position when the target sound source object emits the sound corresponding to the target audio data, and the target sound source object is the sound source object corresponding to the target microphone position.

[0086] Although some of the aforementioned solutions mentioned that the detection efficiency of the sound source position is improved by optimizing the detection process of the sound source position of the audio data, the overhead of real-time sound source position detection is still relatively large compared to a real-time live broadcast, and frequent detection may cause device freezes. To this end, a dynamically adjustable reference detection time interval t(s) can be set, and the target sound source position detection of the target audio data needs to be periodically performed according to the interval duration indicated by the reference detection time interval, so that the time interval between the current target sound source position detection operation and the previous target sound source position detection operation that is located before the current target sound source position detection operation in time is greater than the preset duration.

[0087] Optionally, it is detected whether the time difference between the start time of the current target sound source position detection operation and the start time of the previous target sound source position detection operation exceeds a reference detection time interval; if it is detected that the time difference exceeds the reference detection time interval, a sound source position detection operation is performed on the target audio data of the target microphone position in the live broadcast room; if it is detected that the time difference does not exceed the reference detection time interval, the sound source position detection operation is not performed on the target audio data of the target microphone position in the live broadcast room.

[0088] By adopting the above scheme, the sound source position detection operation can be performed intermittently by setting an appropriate reference detection time interval, and the detection frequency of the sound source position can be appropriately reduced to avoid device freezes caused by high detection frequency as much as possible. At the same time, it can also reduce the delay in the device detection process caused by high detection frequency.

[0089] As an optional but non-limiting implementation, determining a reference detection time interval used when performing a sound source location detection operation may include steps E1-E3:

[0090] Step E1: determining the target detection time consumption when performing the target sound source position detection operation on the target audio data.

[0091] Step E2: If the target detection time is greater than or equal to the preset time threshold, the reference detection time interval is adjusted from the first time interval to the second time interval, and the first time interval is smaller than the second time interval.

[0092] Step E3: If the target detection time is less than the preset time threshold, the reference detection time interval is adjusted from the third time interval to the fourth time interval, and the third time interval is greater than the fourth time interval.

[0093] The device performance of the device end that performs the target sound source position detection is not static. The device performance may become smaller or higher during the detection process. Therefore, the reference detection time interval used for the interval target sound source position detection can be dynamically adjusted. The duration corresponding to the reference detection time interval can be dynamically adjusted as the device performance of the device end that performs the target sound source position detection changes.

[0094] Optionally, when the device performance of the device end performing the target sound source position detection becomes higher, the duration corresponding to the reference detection time interval can be reduced, indicating that the device end can appropriately increase the detection frequency; when the device performance of the device end performing the target sound source position detection becomes lower, the duration corresponding to the reference detection time interval can be increased, indicating that the device end can appropriately reduce the detection frequency.

[0095] The device performance of the device end performing the target sound source position detection can be described by the detection time required to perform the target sound source position detection operation on the target audio data. The target detection time can be determined based on the device performance performing the target sound source position detection operation, and the target detection time is negatively correlated with the device performance.

[0096] If the target detection time is greater than or equal to the preset time threshold, the reference detection time interval is increased from the first time interval to the second time interval, and the time interval between two adjacent target sound source position detections is increased. The detection frequency is reduced as much as possible when the performance of the device is weak, to avoid the increase in device temperature due to maintaining the original detection frequency, which in turn causes the device to reduce its frequency, resulting in a higher delay in the detection process.

[0097] If the target detection time is less than the preset time threshold, the reference detection time interval is adjusted from the third time interval to the fourth time interval, reducing the time interval between two adjacent target sound source position detections, and increasing the detection frequency as much as possible when the performance of the device is strong, to avoid wasting time due to maintaining the original detection frequency, which will affect the detection efficiency.

[0098] The above optional scheme can reduce the sampling rate of detection while ensuring the best spatial audio experience. The idea of ​​game theory is used to balance the losses between the two. An initial preset time threshold and reference detection time interval are given. If the detection time is greater than the preset time threshold, the reference detection time interval will be appropriately increased, otherwise it will be reduced.

[0099] Optionally, the reference detection time interval is adjusted according to a preset step size, and the target detection time is determined based on the performance of a device that performs the target sound source position detection operation, and the target detection time is negatively correlated with the device performance.

[0100] Given a preset time threshold, when the target detection time is less than the preset time threshold, it means that the performance of the device is good, and the reference detection time interval can be appropriately reduced by one step; when the target detection time is greater than the preset time threshold, it means that the performance of the device is poor. In order to ensure a stable live broadcast room experience, the reference detection time interval can be increased by one step.

[0101] As an optional but non-limiting implementation, determining a reference detection time interval used when performing a sound source location detection operation may include steps F1-F3:

[0102] Step F1, determining the device end temperature when performing a target sound source position detection operation on target audio data.

[0103] Step F2: If the temperature at the device end is lower than the preset temperature threshold, the reference detection time interval is adjusted from the first time interval to the second time interval, and the first time interval is lower than the second time interval.

[0104] Step F3: If the temperature at the device end is greater than or equal to the preset temperature threshold, the reference detection time interval is adjusted from the third time interval to the fourth time interval, and the third time interval is greater than the fourth time interval.

[0105] The device performance of the device end performing the target sound source position detection can be described by the device end temperature used when performing the target sound source position detection operation on the target audio data. The device end temperature can be determined based on the device performance performing the target sound source position detection operation, and the device end temperature is positively correlated with the device performance. When the device end performance decreases, the device end temperature will gradually increase; when the device end performance increases, the device end temperature will decrease.

[0106] S330. Determine the target spatial audio coordinates corresponding to the target microphone position according to the target sound source position, where the spatial audio coordinates are used to simulate a three-dimensional spatial sound effect.

[0107] S340: Use the target spatial audio coordinates to adjust and output the target audio data corresponding to the target microphone position.

[0108] As an optional but non-limiting implementation, when determining the target spatial audio coordinates corresponding to the target microphone position according to the target sound source position, the following steps F1-F2 are also included:

[0109] Step F1, receiving the reference spatial audio coordinates corresponding to the reference microphone position, the reference microphone position and the target microphone position belong to the same live broadcast room, the reference spatial audio coordinates are determined based on the reference sound source position, the reference sound source position is used to describe the sound position when the reference sound source object corresponding to the reference audio data emits the sound corresponding to the reference audio data, the reference audio data is the audio data associated with the reference microphone position in the live broadcast room, the reference sound source object is the sound source object corresponding to the reference microphone position, the target sound source position is detected at the device end corresponding to the target microphone position, the reference sound source position is detected at the device end corresponding to the reference microphone position, and the reference microphone position and the target microphone position correspond to different device ends.

[0110] Step F2: adjusting the reference audio data using the reference space audio coordinates, and outputting the audio through the reference microphone position in the live broadcast room according to the adjusted audio data.

[0111] The device end corresponding to the target microphone position in the live broadcast room and the device end corresponding to the reference microphone position in the live broadcast room belong to different device ends. If the processing logic of the audio data of the target microphone position and the reference microphone position is all placed on the device end corresponding to the target microphone position, it may cause greater pressure on the device end corresponding to the target microphone position. For example, if the target microphone position is the microphone position on the host side and the reference microphone position is the microphone position on the guest side, if the audio processing logic is all handed over to the device on the host side for processing, it will cause greater pressure on the host side, which may cause problems such as heating and freezing of the device.

[0112] Based on the above situation, the detection processing of the target audio data corresponding to the target microphone position and the detection processing of the reference audio data corresponding to the reference microphone position can be processed separately. In other words, the detection operation of the target sound source position of the target audio data can be placed on the device end corresponding to the target microphone position, and the detection operation of the reference sound source position of the reference audio data can be placed on the device end corresponding to the reference microphone position.

[0113] For the device corresponding to the target microphone position, it only needs to call the preset spatial audio adjustment interface to receive the reference spatial audio coordinates obtained by the device corresponding to the reference microphone position performing the reference sound source position detection operation of the reference audio data. The device corresponding to the target microphone position will not perform the reference sound source position detection operation of the reference audio data, but will be performed by the device corresponding to the reference microphone position. By performing the sound source position detection operations of the audio data corresponding to different microphone positions in the same live broadcast room separately on the device corresponding to each microphone position, the sudden increase in equipment overhead caused by concentrating on one device can be reduced.

[0114] The technical solution of the disclosed embodiment detects the sound source position corresponding to the target audio data of the target microphone in the live broadcast room, and matches the target microphone with suitable target spatial audio coordinates according to the detected sound source position of the target audio data of the target microphone, and uses the function of the target spatial audio coordinates to simulate the three-dimensional spatial sound effect to adjust the target audio data of the target microphone in real time, so that the target audio data of the target microphone in the live broadcast room has a spatial audio effect, solves the problem of low listening sense and immersion of the audio experience in the live broadcast and connected microphone scene, and ensures as much as possible that the audience has a clearer sense of direction when listening to the sound of each microphone, and achieves better dynamic spatial audio effect. It can be seen that this solution can get rid of the limitation of the microphone position, so that the audio of the connected microphone can produce different sound effects from left to right and from top to bottom.
