Who made this

This was built by a producer, not a software company.

I've spent 25 years in the studio producing, mixing and composing. The analyzer measures with the same standard I use on my own deliveries: that's why the verdict tells you what to fix, not just a number. And how it measures each thing is documented — no black box.

Methodology How every number is measured, step by step. No black box. BPM Index The real tempo range per genre, curated by hand. Set planner Camelot compatibility and a printable sheet to play from. Plugins What the analyzer flags, these fix.

Already monetizing with an audience? I produce for artists who already have people listening and don't have time to sit down and produce. You keep doing your thing; I run the production. Tell me about the project and I'll listen.
