I am not sure if I understand this distinction correctly. If I use Pd at
44100Hz to generate a high frequency wave that aliases, and save it as
a 44100Hz wave file, shouldn't that wave file be subjected to different
aliasing if I play it back at say 22050Hz? What about if I upsample it
to 96kHz? Will the aliasing weirdness disappear if the tone I played was
below 96kHz? Or is it somehow baked into the wav file. I think I am out
of my depth here.

Chris.
