This is in the from of utility code that creates all the bandwidth-reduced tables for the wavetable oscillator. So, you can create any (power-of-2 length) single-cycle waveform, without regards to aliasing, and it creates a wavetable oscillator that's alias-free at any audio frequency.

In my opinion a lot of intro DSP material is overly formal and more difficult to grasp than it needs to be. You're doing a great job of explaining this stuff in a simpler and more direct way. Please keep it up!

I write because when I was figuring this stuff out, there was no internet, and the text books were tough to read and didn't tell me what I wanted to know.
I realise that you were one of the engineers who have worked on a line6 product that I use (that can be seen from some of your other posts) and this is how you had started to learn this stuff... that's a tutorial/lesson in itself, thanks for posting.

I'm putting up a multipart tutorial, including code, on ADSR envelope generators. Way too many words for such a simple thing, maybe, but there were a lot of basic points I wanted to elaborate on. (I wrote most of it, and the code, about six months ago over the holidays, and it's taken this long for final editing...plus I kept thinking of other things I wanted to write about that moved ahead of it.) I've just about finished up all parts today, but I might do a quick video demonstration of ADSR to highlight a few things. The first installment is posted, and I suppose I'll finish and post one per day over the next few days, so the whole thing should be up shortly...
