I have used REW to set the equalizers in my two cars. Since I normally use Spotify as my music source, I thought it wise to use a Spotify pink noise track from Sheffield Labs to do the real-time analysis. I then do an EQ and tweak the equalizer sliders to match a particular house curve. So far, so good, right?

After listening to music for a while, I almost always find myself punching up the treble to get the brightness I desire. This always bugged me, so I took a different approach.

Instead of using pink noise for the RTA, I captured a number of high-quality songs. Lo-and-behold, I found that the music's spectrum always rolled off pretty dramatically above 5k, confirming what my ears were telling me. I then re-adjusted the equalizes to match my house curve using actual music as the basis, not pink noise. It now sounds better to my wooden ears.

What's going on here? Am I doing something wrong? Comments are appreciated.
