<![CDATA[Micropython simultaneous ptt record n play wav]]>Hi, i wanted to use micropython amp skin daughter board code to simultaneous record n play voice over mems mic using mStack fire python code.I do not if m5stack has amp or not? Can we have official m5stack amp.

Upon receiving my m5fire board, i tried the mic menu but can see only voice data plot no echo or reverb. I hardly listen the speaker maybe i have to read data through specific pin?Tips
10khz i.e may reduce noise.

My plan to use button A or encoder for push to talk function and increase volume.
Problem 1, Micropython does not support multithread.Problem 2, i cant increase volume without digital potentiometer or encoder.
