Oh hello,
I beleive I can get the job done pretty esaily.
I will provide you with the C code that you can run on your MCU to get the task done.
I have 5 years of experience working with embedded projects, and I think I'm a perfect candidate.
So can you please message me with more details on the hardware that you are using (i.e what MCU you are using, are you using any external hardware to interface the MCU with the spekaers and microphone.. etc) so we can discuss in detail.
