yeah, there is brown noise....

So called because it's based on Brownian Motion....remeber
that from your science classes....

Give me a mo and I'll get the full defintions for ya...

p.s. Pink noise used to be called Tan noise...some epople
have a problem with Pink, it seems....:)...

white noise

White noise is a sound that contains every frequency within
the range of human hearing (generally from 20 hertz to 20
kHz) in equal amounts. Most people perceive this sound as
having more high-frequency content than low, but this is not
the case. This perception occurs because each successive
octave has twice as many frequencies as the one preceding
it. For example, from 100 Hz to 200 Hz, there are one
hundred discrete frequencies. In the next octave (from 200
Hz to 400 Hz), there are two hundred frequencies.
White noise can be generated on a sound synthesizer. Sound
designers can use this sound, with some processing and
filtering, to create a multitude of effects such as wind,
surf, space whooshes, and rumbles.

Pink noise is a variant of white noise. Pink noise is white
noise that has been filtered to reduce the volume at each
octave. This is done to compensate for the increase in the
number of frequencies per octave. Each octave is reduced by
6 decibels, resulting in a noise sound wave that has equal
energy at every octave

Brown noise has a spectral frequency of 1/f^2. This means,
in English, that there is much more low-end, and there are
many more low-frequency components to the noise. This
results in thunder- and waterfall-like sounds. Brown noise
is so called because, when viewed, the wave follows a
Brownian motion curve. That is, the next sample in the
waveform is equal to the previous sample, plus a small
random amount. When graphed, this waveform looks like a
mountain range. The wave pattern is very predictable.

Bronian motion is famous high-school experiment...

Bascially it lets you see a dust or smoke particle being
moved around by air Molecules...

Moelcules are obviously hard to see but their effect on the
larger dust particles is very obvious...

again, I'll try and find a link for ya...:)...

lol yes i am back ;) at least id like to think i am.

Where can I get cool edit? my dream for this stuff is doing
a mix between Pansonic's stuff and Aube's...but doing really
long simplisitic tonal work. I heard on one of Pansonic's
newer songs called Vaihtovirta a tonal thing where they seem
to be contradicting eachother...that and AFX's song Tassels.
Is there a proper name for that sound? Its incredibly
interesting.

with afx, its track 10 on disc two of SAW 2...the one where
the tones seem to be going off.

but check pansonic's song first...its a better example of
what i mean
