LM393 Mic_Unit Core2 Recording Microphone

[uin00b]

Hi There,

I am trying to record audio from the microphone. I would like to record voice.

I have found the following example on the M5Stack repo:

https://github.com/m5stack/M5-ProductExampleCodes/blob/master/Core/M5Core2/Arduino/record/record.ino

This one takes the internal mic and plays it out the speaker.

https://github.com/m5stack/M5-ProductExampleCodes/blob/master/Unit/MIC_Unit/MIC_Unit.ino

This one uses the LM393 Mic_Unit to display a frequency line on the LCD using the analog pin.

I have tried unsuccessfully to somehow merge the two together.

Question: Is it possible to record human voice using the LM393 or is it simply a sound sensor? I ask because of the results I have been getting and also conflicting information i've been reading.

Thanks.

Hey! I have been trying to do this too. How was your trial going?

I am aftaid that this MICUNIT is just a sound sensor.. but actually LM393 is a mic. It says in the description I believe is for audio sampling and recording. But don’t know if its legit.
Please let me know if you able to figure it out.
