[sdiy] Question about Envelopes

[Roman]

So many answers already, and I like the most Stephan's and Don's. But let me add 2 cents.  Like everything in early basic synthesizer stuff, it comes from radio engineering. An envelope is what you get after detecting/demodulating AM signal. Take a look at envelope detector for example. And plain vanila use of EG is to modulate a signal, so adding an envelope to it.   In Polish we have separate word for the envelope in AM sense, so noone gets confused with a "bag for a letter".   Roman  Dnia 30 listopada 2017 05:48 Chromatest J.

I'm getting my fiance into synths and I was going over her new synth with her, explaining what a VCO is, VCF, etc...    Then I get to the EG (ADSR) and she asks me why it is called an envelope generator?     I said because it generates envelopes.   That wasn't good enough for her, and I don't have a better answer.  I've been playing with and working on synths for decades, even took a synthesis class in college (they had the biggest Roland System 100M, I tell ya), but I don't know why they call it an envelope.  Google searches have not been helpful.   Silly question, but can anybody explain?   -c  ______________________________  Synth-diy mailing list   Synth-diy at synth-diy.org  synth-diy.org synth-diy.org
