Can someone tell me the approach to an audio processor using arduino

So I have done a lot of coding , but new to electronics, and I have taken a project on audio processing , so can someone give me a complete hardware configuration of how to use a microphone and connect it to arduino and filtering processes required.Basically if in get the input waveform in audio frequency from my mic i can work further , so can someone give me the process till the required parts ,Thanks :slight_smile:
