Question about decaying noise generation #62

Hi. The question is about noise generation. More specifically, I would like to generate white/ pink noise that decays (exponentially) by given time parameters. Could anyone share some advice about it? Thanks a lot.

Do you mean you want the amplitude to decay exponentially? If so, you could generate white noise and then multiply by an exponential function.
