Sound Of the Month Edition
Gusty wind effect – achieved by applying double noise
Wind effect spectrogram
330Hz harmonic randomized by both:
- High 44100Hz frequency noise of 1.5 octave on Harmonic – the grains on the image
- Low 1.5Hz frequency noise of 0.5 octave on Envelope – visible as hills
Let’s listen to it:

Zipped falasol project. Quite chilly, huh?

Harmonic noise vs Detuned noise
Harmonic - noise applied to sound envelope
Detuned - noise applied separately to each harmonic
4 harmonics randomized by 1 octave normal deviation with slow frequency of 10hz.

Sound Of the Month Edition
Transition from random pitch sliding into pinkish noise
880 Hz frequency randomized with standard variance of 1 octave and rising change rate
I took a simple 880 Hz sine wave and applied noise of standard variation = 1 octave.
At the beginning the random changes are slow – you can clearly hear the sliding tone. As the rate of changes gains more speed human ear tend to loose track of the tone and start hearing burping sounds. In the end, when the temperature gets really high (higher than tone frequency), the whole wave melts down into one uniform noise.
It’s just like blending a smoothie from an audio tone :)
