[0021] Continue to refer to Figure 2 This diagram illustrates a structural schematic of an embodiment of an audio processing system for simultaneous live streaming in three modes according to this application. The aforementioned audio processing system 200 for simultaneous live streaming in three modes includes: A housing 210 includes N sets of signal input ports 211, first signal output ports 212, second signal output ports 213, and third signal output ports 214, where N is an integer greater than zero; and an audio processing circuit 215 disposed within the housing 210, wherein the audio processing circuit 215 is electrically connected to the signal input ports 211, the first signal output ports 212, the second signal output ports 213, and the third signal output ports 214, wherein: The signal input port 211 is used to acquire an external sound source and convert the external sound source into an audio signal; The audio processing circuit 215 is used to generate a first digital signal at the first signal output port 212 according to the audio signal. The audio processing circuit 215 is also used to generate a second digital signal at the second signal output port 213 according to the audio signal; The audio processing circuit 215 is also used to generate a first analog signal at the third signal output port 214 based on the audio signal.

[0022] In this embodiment, the application receives N digital signals acquired through N input channels, where N is a positive integer. These input channels may include various sources such as microphones, line inputs, computer USB transmissions, mobile phone USB connections, or wireless connections.

[0023] In this embodiment, analog signals such as microphone and line input are converted into digital signals by an analog-to-digital converter (ADC); digital audio signals transmitted by the computer via USB are directly received by the DSP; audio signals input by the mobile phone via USB or wireless connection are also received by the DSP.

[0024] In this embodiment, a standardized digital signal is input to a mixing matrix for mixing to obtain a mixed digital signal corresponding to each output bus. The mixing matrix mixes and distributes the input signals according to preset routing rules to ensure that each output bus receives the required audio signal. The specific calculation process includes: 1) Initialize the output bus: Clear the left and right channel data of each output bus to prepare for receiving new signals; 2) Loop through the input channels: Read and process each input channel; 3) Apply gain and panning: Based on the routing table settings, apply gain and panning control to the input signal to position it in the stereo field; 4) Accumulate to bus: Accumulate the processed signal to the left and right channel buffers of the target output bus.

[0025] In this embodiment, the mixing matrix is ​​configured with an independent set of controllers for each input channel to determine the output content of each output bus. For each instantaneous audio signal (e.g., a sampling point every 1 / 48000 second), the mixing matrix performs the following operations: 1) Initialize the output bus: Clear the left and right channel data of each output bus (computer, mobile phone, camera, monitor) to prepare to receive new signals; 2) Loop through each input channel: • Read input signal: Obtain the current left and right channel values ​​for this input channel.

[0026] 3) Loop through each output bus: ① Query the routing table: Check if the input channel to this bus is "mute". If not, obtain its transmit level (Gain) and pan (Pan) settings. (The routing table is preset by the user). ② Application of gain and imaging: • Transmit level: (L_in × Gain, R_in × Gain).

[0027] • Imaging control: If it is a mono signal (such as a microphone), the imaging device will position it in the stereo field.

[0028] For example, when the sound image is centered, the left and right channels each receive ×0.707 (-3dB compensation); when the sound image is far to the left, the left channel receives ×1.0 and the right channel receives ×0.0.

[0029] ③ Accumulate to bus: Accumulate the calculated left and right channel signals to the left and right channel buffers of the target output bus, respectively.

[0030] 4) Final result: After traversing and accumulating all input channels, each output bus obtains a unique stereo signal that mixes all the specified input signals.

[0031] In this embodiment, the mixed signal undergoes final processing before being sent out. This independent bus processing includes: 1) Bus EQ: Fine-tunes the tone of the entire mix (e.g., improving vocal clarity); 2) Dynamic processing: Apply a compressor or limiter to prevent distortion caused by overload of the total output level; 3) Final level control: Adjust the overall volume using the "fader".

[0032] In this embodiment, the distribution of digital signals to the signal output device is optimized. The distribution path includes, but is not limited to: 1) Computer live stream: Sends the specified mixed audio signal to the live streaming software on the computer via a USB interface; 2) Mobile live streaming: Send another mixed audio signal to the mobile live streaming APP via USB OTG or wireless module; 3) Camera live stream: Output the third-channel mixed signal to the camera via the LINE OUT interface; 4) Real-time monitoring: The headphone amplifier drives the headphones, enabling the broadcaster to monitor all mixed signals in real time.
