Who made this

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

I've been working in audio since 2003, 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.

Working with hundreds of tracks? Music Catalog organizes local songs, versions, BPM, key, artwork and release metadata in one Windows library.

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.
