Audio, from zero.
A free course for anyone who got handed the sound board and a quiet “you’ll figure it out.” It opens on your first Sunday and goes as deep as you care to follow — all the way down to the physics under the noise.
The church soundbooth is the front door, not the whole house. Start there if you are nervous, and the course widens into general live sound, then a working engineer’s craft. Every lesson reads at the depth you choose — the same page serves the volunteer and the veteran.
The plain article
Warm, concrete, no jargon. Read it once and you can do the thing — built for the volunteer who has never touched a mixer.
Go deeper
A panel folded inside every lesson with the real why: the math, the physics, the reason it works. Skip it, or open it.
The Deep End
Level 9 is a full physics capstone for the working engineer. Sequenced, not dumped, and framed for live sound.
