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:
