About the CERtification Program

Audio, understood from the inside out.

Understanding audio isn't just about learning tools — it's about understanding how sound works, how systems are built, and how real-world decisions affect what we hear. The Core Audio Certification Program provides a structured, hands-on foundation for anyone who wants to work confidently with sound, whether in music, post-production, or related audio fields.

Across four interconnected courses, the program guides learners from industry context and workflow, through the physics of sound and human perception, into the technical systems that carry audio, and finally into the creative decisions that shape recorded sound.

Taught by Andrew Scheps, the program reflects how audio professionals actually think and work — connecting theory and practice so learners understand not just what to do, but why it works.

I’ve taken some Audio Fundamentals classes in school. Will this course be similar?

While some concepts may overlap, this course is very different from a typical classroom audio fundamentals class. It’s designed for anyone who wants a broad understanding of the core principles of audio production, as well as insight into the different professional paths in the industry. What sets this course apart is the instructor: world-renowned producer and engineer Andrew Scheps. Drawing on decades of experience, he shares both expert knowledge and personal perspective across a wide range of audio topics, giving you practical guidance that will strengthen your technical skills and creative approach.

How is the course structured? 

The course is divided into four parts that build on each other to give you a complete foundation in audio. It starts with How We Work, which introduces professional workflow and industry context. Next, The Nature of Sound explores the science of sound and how it informs mixing decisions. Audio Electronics covers circuits, signals, and signal flow so you understand how audio moves through gear. Finally, Shaping Sound focuses on digital audio, signal processing, and microphone techniques, connecting technical knowledge to practical application. Each section combines theory, guided exercises, and real-world examples so you learn concepts and immediately understand how to use them in your own work.
