ESP32 audio recording

Postby RHanda02 » Fri Jul 20, 2018 3:36 pm

hello guys,
I am new on working with ESP32, I am currently working on recording audio using a microphone (I2S or MAX9814 with analog output) and saving it in a SD card in the form of wav file. I am confused about which microphone to use?
Also, I tried to use MAX9814 but was unable to get the correct output.
please help.

尝试通过短接增益引脚,修改增益数据。
