Isotropic noise generation
Isotropic noise generation
(OP)
Anyone know how or have experience with generating isotropic noise? I've used normally distributed noise but I can't seem to turn up any material on isotropic. Thanks.

1.79 x 10^12 furlongs per fortnight- that's as fast as I do anything

As we all probably already know, isotropic means equal in all directions. Perhaps the OP could provide more details of the application. Is it related to acoustical measurements?

Assuming VE1BLL is right then isotropic noise is easily generated on land, in a reverberant room.

Relying on reflections to fill the test space with noise may affect the spectrum of the noise.
I was also wondering about the use of that phrase.

time_data = randn(10, 1024); % 1 second of data assuming Fs is 1K
This looks like it is going in the right direction:

I'm trying to do this for noise that is now an isotropic field instead of a 1-D field.
Thanks again.

Might have been a bit quicker getting to here from there if you had explained you were only simulating the whole experiment.
