Er, no ;) Harris is a very common surname. > after some NR 5-10 reading, it looks to me like harmonic_gen is > missing the work pcshft() from the book text is performing, yet > its output seems well-scaled. I think thats for rescaling the domain from [-1,1] to [a,b], but our domain is [-1,1], more-or-less, so we are OK. To make sure we should probably clamp the input to [-1,1]. I could also have remembered it wrong though. > it just occurred to me that it may be feasible to skip the > coefficient calculation in realtime by simply storing these > instead of harmonic amplitude tables. makes lerping difficult > though. IIRC that is what we discussed before. It might well work, but its just an optimisation, so best leave it out for now. - Steve
