Dolby B simulation

Oh HelpfulDad, you've really picked the wrong forum to post those kind of hand waving and incorrect attempts to justify high resolution audio. Your example is simply incorrect - if you actually did the experiment, rather than just talked about it and claimed "it can't work", you'd find that anything below 20kHz was preserved perfectly, irrespective of phase.

This is good...

You can avoid re-running an argument that was had several years ago by reading it here first...
