stm32f103c8t6 home-made USB microphone built on the basis of the microphone module MAX9814.All sound for the video was recorded on this microphone. The most popular microcontroller stm32f103c8t6 is used, arduino lovers call it STM32 Blue Pill. The microphone was tested on windows7 32\64 bit versions and Linux(Raspbian rasperry pi 3b). The ADC operates at a speed of 256kHz,
then the sampling rate is reduced to 32kHz by averaging every 8 ADC samples.
In order to save YOU from problems with the assembly of the project, I provide a ready-made hex file for firmware.
Which can be easily flashed without a programmer , this is suitable for arduino lovers. There are firmware instructions in the video.
