Embodiment 1

[0025] audio processing devices such as figure 1 As shown, it is used for voice and audio collection in high background noise and small space, including power supply, audio input device 101, MCU device 102 and communication device 103; wherein,

[0026] The power supply is used to provide power to the audio input device 101, the MCU device 102, and the communication device 103, mainly to convert the incoming power supply to meet the voltage requirements of each part of the system. The DC-DC conversion chip is used to improve the The conversion efficiency reduces the calorific value and ensures the stability of the system.

[0027] The audio input device 101 includes at least 2 channels of audio input, and also includes a digital potentiometer that can independently adjust the audio signal and a first operational amplifier that amplifies the signal. The audio input section includes a total of 16 independent audio inputs. These 16 audio inputs can be further divided into 12 ba...

Description

technical field [0001] The invention relates to the field of audio processing, in particular to an audio processing device and an audio processing method. Background technique [0002] Audio processing refers to audio processors, also known as digital processors. A digital processor is the processing of digital signals, and its internal structure is generally composed of an input part and an output part. The functions belonging to the audio processing part are generally as follows: the input part generally includes, input gain control (INPUTGAIN), input equalization (several segments of parameter equalization) adjustment (INPUT EQ), input audio processor DA206 audio processor DA206 input delay Adjustment (INPUT DELAY), input polarity (that is, the phase we say) conversion (input polarity) and other functions. The output part generally has signal input distribution routing selection (ROUNT), high-pass filter (HPF), low-pass filter (LPF), equalizer (OUTPUTEQ), polarity (pola...
