he original sound from freesound.org https://www.freesound.org/people/xserra/sounds/317745/ was transformed using sms-tools transformation package to demonstrate the frequency stretching of the sound. The attached sound was first transformed using the sms-tools HPS (Harmonic plus Stochastic Model). The parameters used are as shown below:- Window = Hamming, M=1101 (window size), N=2048 FFT size, t = -100db threshold, minSinDur = 0.07s, nH = 80 (Max harmonics), minf0 = 120, maxf0=260, foet=7,(Harmonic selection parameters) an stocf = 0.5. Time-scaling ONLY. The time axis was divided into 6 equal segment 0 to 1.0 in steps of 0.2. The transform was y= x^(1/3) [0.0,0.0,0.2,0.58,0.4,0.74,0.6,0.84,0.8,0.93,1.0,1.0]
