I guess it's no problem. With sonar it's a bit more complicated, I for example use different averaging windows for slow and fast broadband .. which should affect the 'look' of the noise. I too use 'flat' pseudo-randoms for the fast display, and I average few to get more Gauss looking noise for the slow displays.

Hey SeaQueen .. since you mind .. you know something more about it ? Some links ? I haven't found any. Also about the importance of this in sonar (& ESM) ?
