Resample before frequency analysis

We want to resample before minimum phase reconstruction since that changes the
phase relationship of the sampled signal, introducing a slight bit of noise
from truncated sampling. It's not clear that the frequency domain resampling
method is accurate, so resampling prior to frequency analysis is an alternative
to ensure the resulting frequencies are given the proper phase for sampling.

This also cleans up some micro allocations in loops.
