ABOUT MIXER TOOLBOX

Mixer Toolbox is a collection of free audio engineering calculators and reference tools built by audio engineer James Fleege.

After years of jumping between bookmarked websites for various calculations and reference information, I wanted to bring the tools I regularly use into one convenient place. Along the way, I developed additional tools and features that I hadn't found elsewhere but felt would be useful to other audio engineers as well.

With 17 years of professional experience in recording, mixing, and producing across Nebraska, Nashville, and New York City, I've worked on music totaling over 40 million Spotify streams, with placements in multiple Netflix and Amazon productions.
