We’re a small team of engineers, composers, and developers building audio
tools for people who care about sound. Everything we make is shaped by
real-world use, not marketing trends.
Co-founder
Mastering Engineer
Stan has mixed on Billboard #1 albums for Rihanna, Big Sean, and Wale,
and multi-platinum singles for O.T. Genasis, Jaden Smith, and others. He
trained under Manny Marroquin and built Master Plan to streamline his
own mastering workflow.
Sam is a software developer and composer with a background in audio/DSP,
web, and embedded systems. He builds functional, studio-grade tools that
don’t look like airplane cockpits. If you ask nicely, he can also cook
up a mean marinara...
Developer
Web & Infrastructure
Alex is a software developer who moved into programming after working in
finance. Alex handles web development, APIs, payments, and product
authorization. She spends time listening to music, baking bread, and
thinking about elevators.
We like tools that feel immediate, sound great, and don’t need a manual.
Everything we add has to earn its place, otherwise we leave it out.
If you’re curious about how we make those calls — or what we’re figuring
out as we go — we write about it on the blog.

Null Tests: A Technical Deep-Dive
Null tests are an oft-misunderstood test people use in order to try to understand what a plugin or other piece of gear is doing.

The (Not So) Hidden Feature in All Our Plugins
The other day, a friend and close collaborator of Musik Hack texted Sam and me to report a bug... only... it wasn't one.
It was a key feature we've built into every single Musik Hack plugin since the first release of Master Plan.
In the Room with Sam, Stan, and Alex
Having gotten a few interviews under our belt, we finally decided to sit down without a guest and discuss everything from filter design and DSP, to product decisions, what mastering really means and what mixing engineers are looking for in a workhorse plugin.
