I am looking for a way to access the raw data of an audio signal that is being played on my computer realtime and make use of that data in the arduino IDE. Projects related to this topic usually use an extern Microphone connected to the arduino or read the signal of a headphone jack. The idea is to use this data for base sensitive led light installation for events, so I dont need to use the full spectrum of the data. looking for any guidance on this project. I don't even know if something similar has been done before, but idea seems quite exiting to me.
The Arduino IDE is solely for the development of Arduino programs. It cannot handle other types of data.
A PC application, developed using an IDE for the PC, could be used to read audio data and send instructions or data to an Arduino via the serial port.

How will you know the format of the "raw data" and it's data rate without proper equipment?

Fortunately I have found a well documented project which suits my requirements. It uses processing to handle the intern pc data. https://abhikpal.github.io/blog/2014/02/01/music-visualizer-upgraded
