Just going thru old list emails that I missed. This is interesting,
it seems to work pretty well. It would be nice to see it compared to
other techniques and using other input signals. I quickly added a
lop~ for comparison:

Nice. The graph says it all, it really snuffs out those spikes. Yeah, and it eats way too much CPU, but I enjoy the instructional value of seeing this filter done as signal expressions.

Hi, list, I've created an abstraction for performing weighted median
filtering on a signal using 5 coefficients. It's a real cpu hog. It uses heavily the expr, expr~ and fexpr~ externals, which leads to some redundant calculations on each sample. The test patch enclosed shows how effective this can be for
removing impulsive noises from a signal (like the pops on a record).Chuck

If nature has made any one thing less susceptible than all others of
exclusive property, it is the action of the thinking power called an
idea, which an individual may exclusively possess as long as he keeps
it to himself; but the moment it is divulged, it forces itself into
the possession of everyone, and the receiver cannot dispossess
himself of it. - Thomas Jefferson
