audio recording using USB microphone to ESP32. #629

Is it possible to plug in USB mic into the USB Host shield 2.0, and record stereo audio to the ESP32? And then save the .wav file into SD card. I heard that there is no audio driver for this USB module? Or do I have to write my own drivers as mentioned in the USB_HID library?

Possibly, but you would have to write the driver for that.

hey thanks. So I need to write the driver for USB host shield 2.0 or for the ESP32? If you could share me some links to study these would be great!

I read somewhere that we need to do this: "After writing the driver, Then, you’d have to re-write the tone() function to communicate with the driver. And, you have to deal with the fact that the ESP32 is normally a USB device and you need it to operate as a USB host controller. Not really practical…"

or should i hack to the USB mic's USB head to make it connect to the analog?
