Detailed Implementation
[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.
[0017] Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processes, many of these steps can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the steps can be rearranged. The process can be terminated when its operation is complete, but may also have additional steps not included in the figures. The process can correspond to a method, function, procedure, subroutine, subroutine, etc.
[0018] Example 1 Figure 1 This is a flowchart of a permissioned in-pass matrix mixing method based on multi-source input and dynamic grouping provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where audio signals from multiple devices are mixed and processed on demand before output. This method can be executed by the permissioned in-pass matrix mixing device based on multi-source input and dynamic grouping provided in this embodiment of the invention. This device can be implemented in hardware and / or software, and is generally integrated into a mixer. Figure 1 As shown, the method specifically includes the following steps: S11, Receive the audio input data of the current frame.
[0019] S12. Perform channel separation on the current frame audio input data to obtain audio data for each audio input channel.
[0020] S13. Generate audio output data for each audio output channel based on the audio data and the preset mixing table, and output the audio output data to the corresponding audio output channel after waiting to receive the next frame of audio input data.
[0021] Specifically, this mixing method can be implemented through the audio mixing module in the mixer. External audio frames can be periodic at 1ms, with the latest frame of audio input data sent to the audio mixing module for processing in real time via the external SPI bus. The audio data forwarding function can be implemented through a CPLD hardware processing module, capable of transmitting 20 channels of audio data. It can convert the generated standard SPI signal into I2S and PCM physical port signals and send them to the codec and RF. Simultaneously, it can convert the received I2S and PCM signals from the codec and RF into SPI signals and send them to the SPI port for transmission to the audio mixing module.
[0022] Upon receiving the current frame's audio input data, the audio mixing module can separate the audio input data into channels, obtaining the audio data for each audio input channel. This data can be stored in a local buffer for subsequent mixing processing. While processing the current frame's audio input data, the audio output data from the previous frame can be sent to the corresponding audio output channel via SPI. After separation, the audio data can be processed using a mixing algorithm based on a locally stored preset mixing table. Specifically, matrix mixing can be employed. The preset mixing table indicates which audio input channels' audio data should be used for mixing a given audio output channel, thus obtaining the corresponding audio output data. Upon receiving the next frame's audio input data, this data can be output to the corresponding audio output channel for transmission to the appropriate audio device, such as monitoring headphones.
[0023] In an optional implementation, the preset mixing table includes a correspondence between each audio output channel and an audio input channel for mixing. Correspondingly, generating audio output data for each audio output channel based on the audio data and the preset mixing table includes: for each audio output channel, mixing the audio data of the corresponding audio input channel according to the correspondence to obtain the audio output data. Specifically, in the preset mixing table, audio output channels and audio input channels can be listed as row headers and column headers, respectively. The numbers in the cells can indicate whether the audio output channel in the corresponding row needs the audio data of the audio input channel in the corresponding column for mixing. Furthermore, the magnitude of the numbers can indicate the mixing intensity of the corresponding audio data, etc. The audio output channel and audio input channel can be the same. For example, audio data greater than 0 is used for mixing. An example preset mixing table is as follows: Figure 2 As shown, the audio output channels and audio input channels include Hp1, Hp2, Hp3, UAC, 3.5mm, BLE, and 4Line.
[0024] Based on the above technical solution, optionally, before generating the audio output data of each audio output channel according to the audio data and the preset mixing table, the method further includes: generating the preset mixing table according to the preset audio channel grouping status.
[0025] Specifically, audio channels can be pre-grouped, and a preset mixing table can be generated based on the preset audio channel group status to enable full-duplex communication within each group, while preventing communication between groups. Optionally, the preset audio channel group status includes the channel members within each group and their listening / speaking permissions, thus enabling permission-based intra-group communication. It can further include group ID, the total number of members within the group, etc. The same audio channel can appear in different groups. For example, group 1 includes Hp1, Hp2, and Hp3; group 2 includes Hp1, UAC, and BLE; group 3 includes 3.5mm, BLE, and 4Line; and group 4 includes Hp3, BLE, and 4Line. The preset audio channel group status can be transmitted from the audio control module to the audio mixing module via an external message service and stored in a local cache for generating the preset mixing table. Simultaneously, the audio control module can also use the external message service to transmit parameters required for the mixing algorithm to the audio mixing module for mixing processing based on the preset mixing table. Furthermore, preset audio channel grouping states and mixing algorithm configuration parameters can be freely set by users through device UI, Web, and App interactions, and are managed and integrated by the audio control module. The overall processing architecture is as follows: Figure 3 As shown.
[0026] Further optionally, generating the preset mixing table based on the preset audio channel grouping status includes: setting each audio output channel column as a row header and each audio input channel column as a column header; for each group, setting the cross position of each pair of different channel members in the table to 1, and decrementing the cross position of the row containing the member with only listening permission by 1, and decrementing the cross position of the column containing the member with only speaking permission by 1; the audio input channel corresponding to the cross position greater than 0 in each row is used for mixing the corresponding audio output channel.
[0027] Specifically, 0 can represent not being used for mixing, and the diagonal of the preset mix table can be forced to 0. All cells within the table can also be initialized to 0. Then, each group is processed individually. First, the cells at the intersection of pairs of different channel members within the group are incremented by 1. Then, for members with only listening permissions, the cells at the intersection of their row with other members in the same group are decremented by 1. For members with only speaking permissions, the cells at the intersection of their column with other members in the same group are decremented by 1. After processing all groups, the required preset mix table is generated. When audio input data is received, all channels with values greater than 0 in a row can be mixed together according to this table and output to the audio channel of that row.
[0028] Based on the above technical solution, optionally, the mixing method further includes: if the preset audio channel grouping state changes, then regenerating the preset mixing table according to the changed preset audio channel grouping state. Specifically, dynamic grouping can also be implemented at any time during device use, and users can set or modify the preset audio channel grouping state at any time. Whenever the preset audio channel grouping state changes, the preset mixing table needs to be regenerated for backup; the generation process can be referred to the above description.
[0029] The technical solution provided by this invention first receives the audio input data of the current frame and performs channel separation on the current frame audio input data to obtain the audio data of each audio input channel. Then, based on the obtained audio data and a preset mixing table, it generates the audio output data of each audio output channel and waits to receive the next frame audio input data before outputting the generated audio output data to the corresponding audio output channel. By mixing the audio data of each input channel frame by frame according to the specified mixing table and outputting it to the corresponding audio output channel, it is possible to achieve on-demand intelligent mixing of audio signals from multiple devices. It has the ability to recognize and process specific audio, and can effectively improve the audio amplification and distortion problems caused by signal superposition when multiple channels are played simultaneously, thereby significantly improving the audio clarity and overall listening quality in complex sound recording environments.
