[chuck-users] smoothing and scaling RMS data

Hello, I'm wanting to capture the amplitude envelope from a live source and generate feedback loops... I'm starting by obtaining RMS values, as per the examples on the home site: https://chuck.cs.princeton.edu/doc/examples/analysis/features/rms.ck First, does anyone have a preferred way of filtering the data that effectively captures transients and smoothes the decay? Second, is there a way to scale the range of this smoothed data - that is, map it onto a defined range to use as a parametric control for another UGen? While I'm at it, does ChucK have a filter for DC leak? I'm new to ChucK and am used to work, so I appreciate any help (and patience).
