CNSS model: Colored Noise by Sum of Sinusoids
with Myriam Desainte-Catherine
Sound examples
Synthetic sounds (flat spectral envelope), 44100Hz, 16bits, mono, wav format. Synthesis with 1024 samples using component offset method.
gaussian white noise
CNSS white noise
Harmonicity : noise with L parameter = 0 (insect-like sound) and noise with L parameter = 1 (liquid-like sound)
Impulsive noise : noise with P parameter = 1 (no pulse, white noise) and noise with P parameter = 0 (mpulsive noise)
Time stretching with CNSS model
Original sounds recorded in SCRIME studio, 44100Hz, 16bits, mono, wav format. Analysis with 4096 samples, resynthesized with 1024 samples using component offset method.

Synthetic sound composed by 9 stationary sinusoids (fundamental 1378 HZ) and a colored noise
Original
resynthesized,
analyzed on 21 overlapping frames of size 1024, values are smooth in
time (alpha=0,9)
resynthesized,
with temporal recursive computing of moments (alpha=0,95)
