Code C++ for microcontroller

I have a microphone connected to a microcontroller. A microphone is used to record specific sounds.

I need the code required to detect in real time a characteristic sound within the incoming frame.

The result has to be the percentage of coincidence with the pattern sound.

The detection must be done continuously without losing data. Is recommended to use 2 buffers: one for data acquisition and another one for interpretation.

microcontrollers that I will use for testing: ATTINY85 or ESP32.

We will provide a sound sample we want to detect.

If you don't have experience with audio waves, please, don't bid.

Higher order statistical techniques (such as wavelet transforms and HOS) will be used when processing the signals to make the analysis immune to environmental noise. Do you know something about it?
