Educational - Audio
Educational - Music Business
Rather than list every plug-in developer and microphone manufacturer, I've restricted the list to people you may not have heard of, or that I've found educational in some way.
- Sweetwater - the going rate on any piece of gear. They have a ton of educational material as well, including mic shootouts and more.
- Sonic Circus and Vintage King - the best places to find classic, refurbished gear alongside new, high-end, pro-audio stuff. If what you're looking for is not there, it's because it's consumer-level garbage and these guys don't sell it.
Knowledge is out there.
Go get it.
