I was attempting to generate some band limited white noise today and noticed that it can only go down to 10Hz. Is it possible to extend this? 5Hz would do, 1Hz would be great though
ah ok so unchecking the low cut box expands the lower limit as opposed to it being user selectable?The White PN signal is flat down to the lowest frequency of the chosen FFT length, which is below 1 Hz for 64k FFT and above (for the shortest 8k FFT the limit is just over 5 Hz at 44.1k sampling).
it's predominantly a UI issue as it's not obvious that unchecking the box results in a full range signal, it would be nice to have the option though to limit it to a particular frequency though just to have that extra flexibility in what sort of signal one can create.It was changed for the full range noise. The low and high cut controls are shared between pink and white noise signals, the pink signals follow the pink profile to 9 Hz so allowing lower cut frequencies for them would be misleading. Is there a particular requirement for varying the low cut below 10 Hz for the WhitePN signal?
