krange -- the range of the random numbers (-krange to +krange). Outputs both positive and negative numbers.
For more detailed explanation of these distributions, see:

Here is an example of the gauss opcode. It uses the files gauss.orc and gauss.sco.
Example 170. Example of the gauss opcode.
/* gauss.orc */ ; Initialize the global variables. sr = 44100 kr = 4410 ksmps = 10 nchnls = 1 ; Instrument #1. instr 1 ; Generate a random number between -1 and 1. ; krange = 1 i1 gauss 1 print i1 endin /* gauss.orc */
/* gauss.sco */ ; Play Instrument #1 for one second. i 1 0 1 e /* gauss.sco */
Its output should include a line like this:
instr 1: i1 = 0.252
