Audio output from cp feed to arduino

We're trying to feed the audio output of cp to the arduino and use the serial plotter to read the values. We need a basic circuit and code. Somebody help us. Don't know about arduino that much. I appreciate your understanding thanks.

What exactly is a cp? cd-player?

If you want people to write your code there is a different page for that (but they will want to be payed). What exactly are you trying to do? Just plot the waveform of some audio signal?

Sorry I don't even understand who or what "cp" means to you or what the characteristics of audio coming from it are which makes it difficult to help.

Possibly a few more details might help. Are you trying to plot the detailed "audio" waveform (probably too much for an Arduino) or just its volume envelope or frequency or something else?
