That video was pretty great. He always does a really good job of explaining things in a way that make sense.
I question a couple of the things he showed though. The part about intermodulation distortion, he shows the harmonics show up, but nothing about his test indicated that the distortion was intermodulation distortion rather than aliasing. I’m not saying the test was wrong, I just think it was oversimplified.
Also, the part about the compressor adding side bands to the tone when sidechained with the drums. He didn’t show how it would be different if it was higher sample rate. Maybe he was just pointing out a scenario where it could theoretically cause aliasing, but couldn’t come up with an actual audible example because it’s so minimal.
