Transformation example 1. Analysis/synthesis process performed with the Harmonic plus Stochastic Model implemented in the sms-tools software package (http://github.com/MTG/sms-tools) on http://freesound.org/people/cafeface/sounds/329349/. The parameters used in the analysis are:

Window-type = Blackman; Window-size = 661; FFT-size = 1024; Magnitude-threshold = -70 dB; Minimum-duration-of-harmonic-tracks = 0.1; Maximum-number-of-harmonics = 7; Minimum-fundamental-frequency = 400; Maximum-fundamental-frequency = 700; Maximum-error-in-f0-detection-algorithm = 8; Max-frequency-deviation-in-harmonic-tracks = 0.0001; Stochastic approximation-factor = 0.025.

Transformation parameters are:

Frequency scaling factors: [0, 1, 0.45, 1, 0.451, 2, 0.75, 2, 0.755, 0.5, 1.4, 0.5, 1.5, 1, 1.6, 2, 1.7, 4, 1.8, 8, 1.9, 16, 2.1, 8, 2.3, 4, 2.5, 2, 2.7, 1, 2.9, 0.5, 3.4, 0.25] Frequency stretching factors: [0, 1, 0.4, 1, 0.45, 2, 1.4, 2, 1.405, 1, 4, 1] Timbre preservation: 0 (none) Time scaling factors: [0, 0, 0.8, 1,4, 5]
