Woah, that's a *super* good way to remember that. Thanks. I love examples, and that's great! Charles Henry wrote: >> Any other ideas? > Another option is to use the 'plot as points' graph.

I would do that, but the single points are just too hard to see IMO. > If you're using fft~, you will see the full spectrum from 0 to N-1, > where the second half of the spectrum is the conjugate of the first > half.

Since I now understand that I'm dealing with a graph/display issue, maybe I need to do some heavier lifting? That is, unless somebody can suggest a better way, I guess I'll try and do block-synchronized snapshots, somehow walk/traverse the fft results myself and look for local discretized maximums. Doesn't seem like much fun... The real truth is that although I stand to learn a thing or two by going down this road, I'm probably just reinventing the wheel and could drop in an existing spectrum abstraction or external huh? -jason _______________________________________________ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
