Four Essential Tools for Serious Producers
Three pro charts I actually use in the studio, sent to your inbox instantly — plus one practical mixing tip a week. One email gets you everything.
No spam. No courses pitched every day. Just useful stuff, then the occasional email when I have something worth sharing.
Vocal Range Chart
Know exactly where every voice sits
A clear, visual reference showing vocal ranges from bass to soprano — with the frequencies that matter for EQ, compression, and arrangement decisions. Stop guessing where to cut or boost. Pin this to your studio wall.
- Every vocal type mapped with frequency ranges
- EQ sweet spots for each register
- Printable A4 / Letter format
Note to Frequencies Chart
The reference chart every producer needs on their desk
Every musical note mapped to its exact frequency — from sub-bass fundamentals to the highest harmonics. Essential for surgical EQ, tuning kick drums, identifying resonances, and understanding where instruments live in the spectrum.
- Full range: C0 (16.35 Hz) to B8 (7,902 Hz)
- Colour-coded by octave for quick scanning
- Works for any DAW, any genre
Gain Staging Cheat Sheet
Stop guessing where your levels should sit
The signal path, the sweet spot, and the six-step routine I run before every mix — the one-page reference that has been taped above my desk for the last decade. Fix the gain staging first and everything downstream — EQ, compression, the limiter — gets easier.
- The sweet spot: hit your DAW at −10 dB, peaks at −5
- Six-step checklist to run at the start of every track
- One-page hi-res sheet · printable A4 / Letter

Who's Behind These?
I'm Claudio Passavanti — founder of Doctor Mix, a lifelong recording artist, and the person 819,000+ producers watch on YouTube. These aren't generic PDFs scraped together for a funnel. They're tools I built because I needed them in the studio — and figured you might too.
