Generate white noise.
in RTcmix/insts/std
NOISE(outsk, dur, AMP[, PAN])
CAPITALIZED parameters are pfield-enabled for table or dynamic control (see the maketable or makeconnection scorefile commands). Parameters after the [bracket] are optional and default to 0 unless otherwise noted.
| Param Field | Parameter | Units | Dynamic | Optional | Notes |
|---|---|---|---|---|---|
| p0 | output start time | seconds | no | no | |
| p1 | duration | seconds | no | no | |
| p2 | amplitude | absolute, for 16-bit soundfiles: 0-32768 | yes | no | |
| p3 | pan | 0-1 stereo; 0.5 is middle | yes | yes | default: 0 |
Parameters labled as Dynamic can receive dynamic updates from a table or real-time control source.

NOISE makes white (or pseudo-white…) noise. It is very noisy. It is good for annoying your family, unless your family is a bunch of weirdoes.
The series of random numbers that makes the noise is affected by any calls to the srand scorefile command in the script. If there are no such calls, the random seed is 1.
Output may be mono or stereo.
very basic:
rtsetparams(44100, 1)
load("NOISE")
ampenv = maketable("window", 1000, "hanning")
NOISE(0.0, 2.5, 20000*ampenv)
