Help with synthesizing a high pitched hissing sound

[dajones]

Hello, any idea's to get me in the ball park? I know noise will be a component but I'm just not getting a high pitched hiss sound. Thanks for any help. Cheers

White noise (since it features all frequencies) through a HP filter .

Thanks for your reply. I tried that this morning and has helped me get a bit closer. I still can't seem to get that sssss or well defined hiss sound. I'll keep tweaking, thanks again.

Don't know if that's what you're after, but high resonance settings can lead to really cool sounds . Just tweak the cutoff and resonance on the filter. I'm pretty sure you'll end up with something you like and can use!

Thanks again. I'll play with that and see if I can get any closer.

Non-appropriate switching PSU powering any audio device? Bonus points for using unbalanced cabling.

Hard to say without a clearer idea of what type of thing you're after. I can't think of a more appropriate approach than the aforementioned white noise through HPF thing for a static, undifferentiated hiss. (A BPF with high resonance--or a few in parallel--might be a useful variation thereupon.) For more of a mechanical/electrical whine, I'd suggest something similar with a comb filter to bring out some annoying resonances. Alternately you might try something with one or more narrow pulse waves through a BPF with noise modulating the cutoff frequency. Or you could experiment with FM using high/non-integer ratios; or sample rate reduction to generate aliasing artifacts...there are a bunch of ways to get those sorts of sounds. I hope that provides some food for thought.
