I also was recently introduced to green noise. From Wikipedia:
- The mid-frequency component of white noise, used in halftonedithering[19]
- Bounded Brownian noise
- Vocal spectrum noise used for testing audio circuits[20]
- Joseph S. Wisniewski writes that "green noise" is marketed by producers of ambient sound effects recordings as "the background noise of the world". It simulates the spectra of natural settings, without human-made noise. It is similar to pink noise, but has more energy in the area of 500 Hz.
Wondering how I might generate this other than using something like a bandpass filter tuned to 500 Hz using pink noise. I want to generate it in the analog realm.
TIA,
Thomas
