All I'm saying is that "music" is not a sine wave (although I do have
one release that is nothing but sine waves). Even though music can
theoretically be transformed into a series of sine waves that repeat
to infinity, inverting the polarity of a piece of music is not going
to shift each frequency by a certain number of degrees. I prefer a
separation from the physics and math term, which I understand, and
the audio engineering concept, which I believe is misnamed. I think
you're agreeing with me, when you say that "phase is for sinusoids
only" - and since the OP was talking about vocals, it's clearly a
case of other waveforms.

Sorry, I think you're wrong here. Since only a pure sinusoid has the
concept of "phase" I believe this term is actually quite correct. PI
radian / 180 degree phase shift = inverse polarity. For other
waveforms you usually talk about "period" or "cycle", but phase is for
sinusoids only. Not sure what audio engineers think about this (they
sometimes do use funny terminology) but this is how the physics and
math guys see it.

It's a bit misleading when folks refer to this sort of thing as
'phase' - a
more appropriate term would be 'polarity.' Only a pure sine wave
has a
180-degree phase shift when it's polarity is inverted, but any
changing
waveform will obviously not have its features shifted in phase at all,
because they remain at the same precise time.
