re: random value
These are all great solutions. I didn't expect to see such good answers to
this problem. I tried various other approaches too, such as writing the
output of noise to a table, and then accessing the table values using a
phasor but I couldn't quite figure out how to write the rand

Attached is my code relating to this. There's a c++ function, which
takes a dummy

No, this isn't a problem - I have working code which gives different
random value
Hi, James.
Even if calling an external random function, don't you always have the
problem of calling it with a different seed each time to get a different
stream at each run?
If the external function uses, for example, time() to set a different seed,
I feel that it would be easier to have a primi
Thanks everybody.
Looking forward to the new random addition in stdfaust.lb

This is a bit of a limitation of faust for generative-type work.
Faust's no.noise gives part of what one wants from randomness: the
values in its sequence are uncorrelated with each other. However, it
fails to give you the other thing one would want: it is deterministic,
i.e. it gives the same seq
I'm glad this question has been asked,
was wondering myself how to do more generative work with Faust.
Has anybody some more 'generative' examples to study ?
Thanks

Hi Bob,
You could use latch to sample the random number stream. However, it's more
efficient to do something that can be completed at compile time, e.g.,
rtz = (*(1103515245) + 12345) & mask;
rt(i) = seq(j,i+1,rtz) / RANDMAX;
process = 1 <: par(i,N,*(rt(i)));

Hi, Bob.
You could reduce the rate of a process by using sample-and-hold functions
as in the example below:
import("stdfaust.lib");
mynoise(seed, period) = random / RANDMAX
with {
mask = 4294967295; // 2^32-1
random = +(seed) ~ ba.sAndH(clock, *(1103515245) & mask); // "linear
congruential"
clock
Hi,
I've pondered this code for a while, and am failing to understand how to
declare a variable which has a single random value. Of course this code
creates random values at the sample rate. How would you get just one value
instead of a constant stream of values?
mynoise = random / RANDMAX
with{
11 matches
