This is a trnsformation of the original sound: http://freesound. Org/people/ricemutt/sounds/23933/ , with the parameters:. For synthesis:window type: blackmanwindow size: 801fft size: 1024minimum f0: 100maximum f0: 2500number of harmonics: 20 (we don't need too many harmonic here)threshold: -100stochastic decimation factor : 0. 1minimum sine duration : 0. 1. For transformation :frequency scaling factors : [0,1,0. 4,1,0. 6,0. 9,1. 0,0. 5,1. 2,0. 3,1. 4,0. 6] <- (make frequency variation steady)frequency stretching factors : [0,2,0. 5,1,0. 51,0. 7] <- (create a frequency variation, high->low )timbrepreservation : 1 <- (no change)time scaling factors : [0, 0, 0. 8, 1. 5,1. 0,2] <- (make some "free fall" feeling).
