could someone take a second to explain which one of these two objects (or any other for that matter) is better for envelope following and why? I have always used snapshot~ but recently started using avg~ and it seems to work/sound better...but I am not sure why...

avg-vs-snapshot

avg~ reports a float (control-rate) of the mean average of the amplitude that it has received between bangs that you give it.

this is very different from snapshot~, which outputs a float of whatever signal it is receiving at a millisecond interval that you set via it's arg.

still different is average~, which outputs a signal average based on its input signal in sample intervals that you designate via its argument, or an integer message. this object is more flexible, having 3 different modes at which it can average- bipolar/rms/absolute.

all this is covered in the documentation/help files.

for an explanation of averaging, check out:

the preferred method for envelope following would generally be average~, or you could check out rampsmooth~.

because snapshot does not measure power at all, it outputs

if you want messages, meter~ can be a possible equivalent

because snapshot does not measure power at all, it outputs
the value of the current sample.

if you want messages, meter~ can be a possible equivalent
to avg~/average~


for envelope following, you can also use slide~.

avg~ vs snapshot~
