Hi Josh,
     The [sig~] object seems to be used as a place holder in that video-- 
a way to say, "here are some initial values for [expr~], which can later be changed by using something else as the input."  Have a look at the 
help patch for [expr~] for more info.
     Have you looked at the tutorials in doc/3.audio.examples?  For 
example, see the "scratch machine" in B07.sampler.pd, and the attack detector in C07.envelope.follower.pd.
