I also have a cremez module that can be used to design equi-ripple filters
with complex Hermitean coefficients. It is like the current remez in signal
but more general. It uses the fft for interpolation, is written in cython
and can also be used for L_inf fitting of functions on an interval with the
coefficients naturally returned as a Chebyshev series. I don't know how much
time I will have to polish it up, nor do I know the best place to put it,
although I've been thinking scipy.optimise would be a good spot.
