I have seen a few projects for displaying frequency content of music. However, I am dis-satisfied with what I have seen.
FFT is obviously not practical if possible on an arduino.
Therefor, I want to go with an external solution.
The MSI MSGEQ7 is a fantastic solution.

It isn't readily available though. I can only find it on a users' site (5$) AND it is SMD.
I figure that there has to be more ICs available that do similar things. I would love to find something more readily available and maybe less expensive. (Not that 5$ is huge but it's hefty for an IC)
Does anybody know of any good frequency spectrum analyzation ICs?
