Thanks, you are right about the message format. My questions is with regard to a different behavior of sinesum vs cosinesum in Pd(0.45.0) when specifying the partials though. > On Wed, Jan 29, 2014 at 6:01 PM, Peter P. <[email protected]> wrote: [...] > > not sure if I am getting something wrong here, but it seems that > > sending the message > > > > ; cosinesum array999 1 should of course read: ; cosinesum array999 512 1 > > does something different (besides an obvious phase shift between sine > > and cosine functions) to the resulting contents of that table: > > > > the first partial on cosinesum seems to be the DC component, while the > > first partial in sinesum is the, well, first partial. > > > > Accordingly, the second partials have double frequency in sinesum as > > in cosinesum. > > > > Perhaps this is intentional, but was just wondering... best, Peter _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
