looking for envelope follower info

[Kevin Day]

Hi all,

I would like to build an envelope follower.  I've never built any
musical electronics before, but I am reasonably handy with a soldering
iron, so a schematic using (hopefully) easily available parts might be
sufficient.  Ideally, of course, more information will be available such
as design notes, full parts list, etc.  I didn't find anything very
detailed on the net... does anyone have any suggestions?

Thanks.
