 ͏    Follow-Up: https://trac.ffmpeg.org/wiki/denoise#favg

 ͏    Derived from my recent research on available denoise techniques.\\
 ͏    This seems to achieve theoretical best compressibility enhance:
 though unsure for subjective quality.\\
 ͏    .\\
 ͏    Some past research seems to prove the applicability:\\
 ͏    https://www.rationalqm.us/hiq/smoothhiq.html\\
 ͏    (sort of [https://ffmpeg.org/ffmpeg-filters.html#smartblur
 ͏"smartblur"] derived Local Means?)

 ͏    The idea should work for audio too.
