That's incorrect, distortion products spread both upwards and downwards in frequency. The easiest example to analyze is x^2, which corresponds to the spectrum convoluted with itself. From there it's easy to expand into polynomials.
Anyway, what you're describing is pretty much a single step in a standard blue noise algo iteration.
- tlb 3y agoYou’re right. While a pure tone can only have higher harmonics when distorted, multiple tones can produce the difference frequency. And noise has every tone.
- FreeFull 3y agoEven when distorting a pure tone, the harmonics will reflect back down once they go past the Nyquist frequency.
- galangalalgol 3y agoAnd what happensnif you apply a high pass filter to white noise? That would have been my naive approach.
