A fast building white noise with added filter sweep and fade-out, layered with a pulsating synthesized bass tone with a slow attack and an affected decay.
Sounds of liquid-oxygen and liquid-nitrogen cooling towers next to a large industrial building, producing several different varieties of white noise as i walk past them.
Rhythmic noise from some kind of loud machine, recorded outdoors, as evidenced by birdsong in the background. I honestly have no idea what was making the noise, though, and my notes are missing. Mysterious!.
Leaves-recording with: dynamic glissando, frecuency glissando, panning and acceleration sounding at the same time with a noise. Ends with a white noise which starts at 0 hz and grows until 7500 hz and go back again at 0 hz.
