Put simply, if you distort a signal in the same way, on both sides, you create odd harmonics (distortion which sounds like square waves, in a roundabout way).
What I have understood for quite some time, though, is that when you affect both sides of the audio signal (the positive and negative) differently, different harmonic structures are generated and enhanced.
Now that stuff is far on the horizon of my menial coding world, so I don’t bother with it. Distortion happens almost all the time in the electronic circuitry, you can’t emulate that stuff (but the developer can make it sound like he does by adding noise into the ‘analogue emulation’ by generating/playing white noise through the effect. Analogue distortion is ‘real’ it’s electrons passing energy to each other, and the management of that energy using resistors, capacitors, diodes and all those kinds of things.

If you got past the title, then welcome to this post! Prepare for small nerdĭigital distortion is mostly ‘ugly horrible’*, compared to analogue distortion, but it always depends on what you’re looking for in the moment Hard-clipping, wave-folding, sample-rate and bit-rate reduction, complex wave-shaping… these techniques can not be implemented in analogue circuitry (that I’m aware of).īut folks try to emulate what analogue distortion does to sound in software all the time.
