One note to make here (more of an addition to your answer than anything else) is that very often nowadays most algorithms include an oversampling step before the processing and a downsampling step (to bring the audio back to its original rate) after the process. Before the latter, all high frequencies that would be aliased are filtered and the result is less aliasing in the final product. | |

And then we need an LTI filter that has for its step response something like a critical or over-damped 2nd-order response: $$ y(t) = (e^{-t} - e^{-2t}) u(t) $$ It's possible that the OP's algorithm did zero-crossing detection and the output would look the same no matter what periodic waveform went in. | |
