Here's a simple one, (at least I'm guessing it is):

	I'd like to find a simple and effective way to apply the
	envelope of one signal to another without effecting frequency
	spectrum. Both signals are .wav files using soundin. I 
	expected I could use follow but I can't find a way to use
	its output, kr, with anything but a generator like oscil.
	So far I have ok results using balance, but it strikes me
	that there is a better way to do this. The specific thing
	I'm trying to do at the moment is to apply the envelope
	of a sample of ocean waves to another soundfile which happens
	to be a relatively regular texture of granulated sounds. 
	(BTW- I'm still using 3.47, just in case there are any new opcodes
	that handle this better in .48). It seems simple enough, I 
	just haven't had occaision to do this before and would like
	advice on better ways to do it. Thanks....

This sort of thing is exactly what balance is for. If it doesn't seem
right, try adjusting ihp from the default of 10. I find something in the
range of 12 to 18 usually works best. Also make sure kr=sr. Balance adjusts
its scaling factor once per control frame (ps jpff et al., Life would be
much easier if balance updated every sample instead of every frame).
Without kr = sr you get amplitude jumps and buzzing at a frequency of kr.

I thought that the follow opcode was for this kind of reshaping.  Have
not used it for a while though.
