First, let me agree with the notion that through interference of the supersonic elements, audible artifacts through reverberation can come into existence. The early reverb can easily transfer some energy into the audio band and the (partially non-linear) reverb tail of any non-dead listening

Theo, My tl;dr answer to your question is it's difficult because even if it's digital, it's not digital. Ever. It's always analog. Like you, I'm a university EE (and Comp. Sci.) because I wanted to go into chip design. This was back in the early 80's. So maybe my classwork was different than

Comments in line. There's this preoccupation I have since the advent of going "digital", let's say since I heard music being played on CD in the early 80s. I grew up with access to electronics equipment that would generate "square waves" in some sorts of analogue fashion, including originally

How about square waves made from BLITs? That’s a standard approach. To hear the difference, try the test oscillator in Logic Pro. It has an anti-alias option to switch between a naive square / pulse wave, which is useful in some cases, since it has only 2 values, and a BLIT version, which
