Dear Tyler and Christian,

Theoretically yes, as it most likely uses zero-phase non-causal filter i.e.
a spike like a needle will be decomposed into a triangle, the left half of
which is 'information from the future'. Tim recommends slope fit and
subtract solution he supports in SIFT (that's for high-pass; for low-pass,
use cleanline).

Christian, is clean_rawdata high-pass filter zero-phase and non-causal? Or
was it zero-phase and causal?
