OK, I didn't know how you were defining mirror().

changing this to :
f(x) = x - sgn(x)*abs(x)^a
allows 'a' to be continuously variable, not just an odd integer.
sgn(x) is the signum fun
In the same vein: a family of smoothed sawtooth waves
f(x) = x - x^a
evaluated from x = -1 to +1
where 'a' is an odd integer >= 3.
the greater 'a', the greater number of harmonics.

4x-3 transforms the interval .5 to 1 into -1 to 1.

dB
answer is correct, expression was wrong.

wouldn't using varying ZCR be defeated by frequency modulated or bell tones?
One could also craft a very noisy signal with a perfectly periodic ZCR.
