I watched a really cool youtube video about additive synthesis. I wonder how did he or she make the "gen~ fold" Here is the link and image. And the youtuber uploaded the project file on the blog. See the description,

question-gen~-fold

The code is in the youtube description :-)

It isn't folding; it's additive synthesis -- just adding up sinewave partials to recreate classic waveforms.

Could this thing be modified to run off of a phasor? I'm kind of codebox illiterate.

the gen fold seems to be missing in the provided patcher.

you can put the pong~ object instead of it and get simmilar results

//partial = cos(i * ph + PI*i*i/np) / pow(i, spectralSlope);

partial = sin(i * ph) / pow(i, spectralSlope);

//partial = cos(i * ph + PI*i*i/np) / pow(i, spectralSlope) * np_frac;

partial = sin(i * ph) / pow(i, spectralSlope) * np_frac;

//partial = cos(i * ph + PI*i*i/np) / pow(i, spectralSlope);
  partial = sin(i * ph) / pow(i, spectralSlope);

//partial = cos(i * ph + PI*i*i/np) / pow(i, spectralSlope) * np_frac;
  partial = sin(i * ph) / pow(i, spectralSlope) * np_frac;

Question | Gen~ fold ??
