How to record audio and save it to wav file using Electret Mic Amp - MAX9814?

I tried to use the code that you sent on other post

RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2, ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC2, ENABLE);
RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3, ENABLE);

Not really sure what is this code means as the code was undefined in my vscode.
