[0039] The audio channel parameter adjustment method, device, medium and program product provided in the present application are intended to solve at least one technical problem existing in the prior art.

[0040] An embodiment of the present application provides an audio channel parameter adjustment method, which can be used in mobile phones, computers, mixers, mixing consoles, digital audio workstations, and other terminals that can be used for audio channel parameter adjustment.

[0041] Alternatively, if Figure 1 , Figure 2 As shown, the audio channel parameter adjustment method of the present application includes:

[0042] S101: Detecting parameters of an audio channel.

[0043] Optionally, the parameters of the audio channel include volume, pan, equalizer, etc. In live performances or audio production and other scenarios where the audio channel is required, the parameters of the audio channel can be detected in real time (detected at a preset frequency or a preset period), and the parameters of the audio channel can be compared with the historical parameters of the audio channel, and whether the parameters have changed can be detected based on the comparison result.

[0044] Optionally, each time a parameter of an audio channel changes, the changed parameter may be recorded, and the changed parameter may be compared with a historical parameter recorded last time to detect whether the parameter has changed.

[0045] S102: If a parameter change is detected, the grouping corresponding to the audio channel is obtained, and the changed parameter is applied to the audio channel in the grouping.

[0046] Optionally, the grouping includes at least two audio channels, and the grouping is created based on a received grouping instruction.

[0047] Optionally, after detecting that the parameter has changed, it is also possible to detect whether the grouping corresponding to the audio channel where the parameter has changed has the same parameter change (such as the values ​​of the same parameter have all changed to the same value). If so, it is determined that the parameter change is caused by parameter synchronization, and no subsequent operations are performed. If the same parameter change has not occurred, it is determined that the parameter change is not caused by parameter synchronization, and subsequent operations are performed.

[0048] Optionally, after detecting the parameter change, it may also be detected whether the audio channel corresponding to the parameter change has a corresponding grouping. If no grouping exists, parameter synchronization is not performed.

[0049] Optionally, the creation of the grouping includes: in response to the selection instruction, obtaining the audio channel corresponding to the selection instruction; if it is determined that the grouping instruction corresponding to the selection instruction is received, the audio channel corresponding to the selection instruction is associated and grouped to obtain the group corresponding to the grouping instruction, and the identification information of the group is determined. The identification information is unique, and different groups correspond to different identification information, and the audio channels in the same group are identified by the identification information.

[0050] Optionally, each audio channel corresponds to a group, and different groups can be set for different scenes, working environments, users, music types, changed parameters, parameter change ranges and other classification information, so that different groups are set for the same audio channel according to different classifications. After detecting that a parameter has changed, the group corresponding to the audio channel with the parameter change is determined according to the current corresponding classification.

[0051] Optionally, before responding to the selection instruction, an audio channel display interface may be displayed to display the audio channels available for grouping, and the selection instruction and the grouping instruction may be obtained through the display interface. The user may input the selection instruction and the grouping instruction by touching the screen, displaying a specific gesture, or voice input.

[0052] In one embodiment, an audio channel display interface is displayed based on a user's instruction, and the audio channel is displayed using the audio channel display interface. The user inputs a selection instruction for selecting an audio channel through the interface. The terminal determines the selected audio channel according to the selection instruction and displays the selected information of the audio channel. It is detected whether a grouping instruction indicating associated grouping is received, and if so, the selected audio channel is grouped.

[0053] Optionally, in order to store the information of the audio channel and improve the speed of parameter synchronization, before the group is created, it includes: creating a data object, the data object includes a channel address memory; using the channel address to store the information of the audio channel, the information includes a channel index, a base address, and an offset.

[0054] Optionally, the channel index is used to identify the position of the audio channel in the memory, and the channel index may also include identification information of the group corresponding to the audio channel, and the group to which the audio channel belongs may be identified by the identification information. The channel index may also include the code and name of the audio channel and other information that can be used to find and identify the audio channel.

[0055] Optionally, determining the offset includes: acquiring a storage space of the audio channel, and determining the offset of the audio channel according to the storage space. Specifically, the offset of each audio channel can be determined according to the size of the audio channel space.

[0056] Optionally, the data object also includes a queue and a marshaling thread, and obtaining the marshaling corresponding to the marshaling instruction includes: determining the queue corresponding to the marshaling, storing the marshaled data in the queue; detecting a parameter change, including: adding the changed parameter to the queue, and parsing the parameter using the marshaling thread. The marshaling thread performs parameter synchronization operations based on the data in the queue, and the marshaling data can be the parameters of the audio channel changes in the marshaling, the audio channel is turned on or off, and other data that require the marshaling thread to perform parameter synchronization or processing.

[0057] In one embodiment, before the grouping is created, the offset of each audio channel is determined according to the storage space size of each audio channel. A queue, a grouping thread and a channel address memory are created. Wherein, the queue can be a circular queue, and the storage format of the circular queue can be a structure to improve the storage speed. The queue stores data from the grouping that needs to be processed by the grouping thread. The created grouping thread is used to synchronize parameter changes from the channel, and the created channel address memory is used to store information such as the channel index, base address, and offset of each audio channel. The actual address of the audio channel can be determined according to the channel index, base address and offset. When it is detected that the parameters of the audio channel have changed, the changed parameters are added to the queue so that the grouping thread can process.

[0058] Optionally, obtaining the grouping corresponding to the audio channel includes: using the grouping thread to parse the changed parameters to obtain the actual address of the audio channel; and locating the audio channel according to the actual address and information stored in the channel address memory.

[0059] In one embodiment, the changed parameter may include the actual address of the audio channel, and the grouping thread takes the changed parameter from the queue, parses the parameter, and obtains the actual address of the audio channel. The audio channel where the parameter change occurs is determined based on the actual address and the channel index, base address, and offset of each audio channel stored in the channel address memory, wherein the actual address of each audio channel can be determined by the channel index, base address, and offset in the channel address memory, and the actual address is compared with the actual address corresponding to the changed parameter to determine the audio channel where the parameter change occurs. After determining the audio channel where the parameter change occurs, the grouping to which the audio channel belongs can be determined based on the identification information corresponding to the audio channel, and then all audio channels corresponding to the same grouping can be determined based on the identification information of the grouping.

[0060] Optionally, applying the changed parameters to the audio channels in the grouping includes: using the grouping thread to obtain the grouping corresponding to the audio channel, determining the actual address of the audio channel in the grouping according to the base address and offset of the audio channel in the grouping; and applying the changed parameters to the audio channel in the grouping based on the actual address.

[0061] In one embodiment, the base address can be obtained by S=R-(I*F), where R is the actual address, I is the channel index, F is the offset, and S is the base address. After obtaining the base address, the actual address of each audio channel in the grouping that needs parameter synchronization is obtained by S+1*F. Based on the actual address, the changed parameters are distributed to the audio channels in the grouping.

[0062] The following is a specific example of audio parameter adjustment to illustrate the audio channel parameter adjustment method of the present application.

[0063] In one embodiment, Figure 2 As shown, the offset of each audio channel is determined according to the storage space size of each audio channel, and the actual address of each audio channel is determined based on the offset. Create a queue, a grouping thread and a channel address memory, and store the channel index, basic address and offset of the audio channel through the channel address memory. Among them, the number of audio channels is 4, and the 4 audio channels are divided into the same group. The basic address R of the audio channel in the group is 100, the offset (address offset) of each audio channel is F=10, and the channel index \(I\) is the unique identifier of the audio channel, which is used to determine the position of the audio channel in the memory. There are 4 audio channels: channel 1, channel 2, channel 3, and channel 4. The volume parameter of audio channel 1 changes, the new value is 75, and the old value is 60. Add the changed parameters (including the parameter type of the volume, change data, timestamp and other data) to the created queue. The grouping thread obtains the changed parameters from the queue, determines the grouping that needs to be synchronized according to the parameters, and calculates the original address of each audio channel in the grouping. Now it is necessary to calculate the address of channel 2 / 3 / 4. It is known that the base address R=1000, offset F=10, and channel index 0 of channel 1 are calculated according to the formula s=R-(I*F), and the actual addresses of other audio channels are obtained based on the base address, where S+1*F represents the actual address of the second audio channel, S+2*F represents the actual address of the third audio channel, and S+3*F represents the actual address of the fourth audio channel.

[0064] The volume of channel 1 changes from 60 to 75, and based on the calculated address of the audio channel, this parameter is applied to the other audio channels of the group (channel 2, channel 3, channel 4).

[0065] The audio channel parameter adjustment method provided in this application allows users to dynamically create and adjust audio channel grouping to adapt to the ever-changing audio production needs. Users can freely add or remove channels during the grouping process without interrupting the ongoing operation, thereby enhancing the flexibility of the grouping. Through this grouping, users can complete the grouping and parameter synchronization adjustment of audio channels without complicated operation steps, and through the optimized data structure and event-driven mechanism, it is ensured that efficient and stable performance can be maintained when processing a large number of audio channels.
