Audio interfacing

Hi I want to read in the audio out coming from my computer to my arduino uno and make almost like a view meter that way so that my computer still plays music and doesn't need an aux. Is it possible to interface the audio out on my Ubuntu to my arduino

Did you mean a VU meter? If not, what did you mean?

An Arduino is not a good choice for this. Buy a kit a VU meter if you want to learn to solder.

This is an expensive one:

There are probably cheaper ones out there that Google can find for you.
