[Numpy-discussion] [OT] Interpolation of an unevently sampled bandwidth limited signal

I have several cases of hand digitized spectra that I'd like to resample these spectra at even spacings. My problem is that cubic or RBF splines often result in an unacceptible over-shooting. Is there a python module that provides something similar to sinc interpolation on unevenly space sampled signal? Nadav.
