I have been doing home recording since mid-90's with a computer, mixing live sound since early 80's, and have had undergraduate and graduate courses and degrees involving acoustics and signal process. I took this course last year at roughly the same time frame.

While it is an introductory course, it also goes deep enough to make it worthwhile for someone with my background.

My 'AHA' moment in the course, was that when applying reverb in a bus in my DAW, that it should be post-track-volume fader. I have used a couple of DAW softwares in my lifetime, and countless live sound mixing desks (though my environments that I mix in have almost never used artificial reverb) and this was the first time the light came on for me that this is where you put reverb and sometimes delay. Yes, the course was kind of basic, but there are concepts in there for everyone on this forum.

One thing I hear in many home recorded tracks is comb-filtering due to recording too close to reflective surfaces. The instructor does a great job explaining what comb filtering is and how to avoid it.

It's a free course, and probably worth several hundred dollars at minimum if you feel like you are a newbie, or would like a new perspective on the topic of home recording and production. One note, the syllabus makes mention of covering MIDI, and in the course offering last year, that pretty much was dropped off the actual course material offered.
