-    - Sliding decimation methods :func:`.filters.sliding_average`, :func:`.filters.median_filter` and :func:`.filters.sliding_filter` are related, but use a sliding window of `n` points instead of complete decimation of `n` points together. It only works for 1D traces or 2D multi-column datasets. Note that :func:`.filters.sliding_filter` is implemented through a simple Python loop, so it is not very efficient.
