Better auto-choice of frame sizes for convolution/dispersion/etc

[mhvk]

Should pick a sane number of input samples for FT. Should also include extra padding to avoid edge effects.

If you mean for FFT efficiency, I use this: https://docs.scipy.org/doc/scipy/reference/generated/scipy.fftpack.next_fast_len.html

Partially that, but more generally a smart choice for the amount of padding that gets discarded (beyond the convolution window). Plus perhaps your near-Nyquist taper function in the frequency domain.
