hello, sorry, i don't have time, i'm not at home. so it's a short answer.
I try 2 other way to use msd as an audio generator. it's not very efficient either.i think it should not be very difficult to make a msd~ external. anyway, for this aplication, pmpd~ external should be easier to use.
there is no message to change the mass in msd, because equations are linear. i.e mass=1, K=0.1, D=0.1, F=0.1 is the same than mass=10, K=1,D=1,F=1: ++ c marius schebella a écrit :
one more. not at all cpu-friendly but a real msd. m. Andy Farnell wrote:You're a hero Chuck. This tallys well with the equations in Perrys book. What I was missing is the step where you get the transfer function.I made (attached) a little test rig. What isn't looking right is the underdampedbehaviour. I was expecting to see a decaying oscillation around the top point. Maybe my test has errors. a.On Sat, 15 Mar 2008 19:16:29 -0500 "Charles Henry" <[EMAIL PROTECTED]> wrote:Note, when c goes to 0, we get a harmonic oscillator at angular frequency w=k/m rad/sec, which is correct. When we increase the damping, we get terms of e^(-0.5*c/m*t) which damps the solution.made a typo here: angular frequency w=sqrt(k/m) rad/sec and f=sqrt(k/m)/2pi Hz _______________________________________________ PD-list@iem.at mailing listUNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list------------------------------------------------------------------------ _______________________________________________ PD-list@iem.at mailing listUNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list------------------------------------------------------------------------ _______________________________________________ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
