The 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.
The resulting sound was then transformed using only frequency stretching.
The FREQUENCY STRETCH parameters used were [0.0,1.1,1.0,1.05]
