This looks very, very, very good
Though actually this graphic is relative small it virtually creates the impression (using the 3D perspective) as if Stereo Tool is a big and massive peace of hardware (reminds me of a cuboid mainframe computer).
The only thing:
Reading "Stereo Tool - professional audio processor" there is this little voice in my head that asks: "Why is it necessary to say, that it is professional ?"
Almost every (for sure: many) software publisher use this phrase - so is this really an adjective that helps to convince people to try Stereo Tool ?
And suddenly I had the (weird ?) idea to re-arrange these words:
"Stereo Pro Tool - audio processor"
Though I cannot exclude either that a phrase like "Stereo Pro Tool" would violate an array of protected trademark phrases by Avid (formerly Digidesign) and maybe would lead to severe problems for Hans, because some people (lawyers and judges) might come to the conclusion that something like "Stereo Pro Tool" is too close to "Pro Tools".

Back to reason:
I especially like the look (and feel !) of the oscilloscope waves.
In this frozen state (in contrast to their instability in real processing) they really look like true waves of water (play

Beach Boys - "Surfin' USA" and you know what I am talking about).
So, yes indeed it looks very good (as first beta version of a central graphic element) !
