Help request! Making a 'hiss' echo

Hi there,

I'm trying to make a 'radio transmission' style voice effect that matches that used in the X Wing and TIE Fighter series computer games.
The effect I need I'll add an example of in a bit, but it sounds like a radio transmission.

I can get the voice sounding like it is coming over a radio using the equaliser and high pass filters, but what I can't get is the static hiss that accompanies it.

I can add white noise in the back ground, but in the game, the noise isn't constant - it is like an echo. It's as if someone has put a .1 second delayed echo, then convereted the echo into a static hiss rather than a voice.

Any way of doing this in Audacity? Will try to get an example.

Thanks!!

Either post a link to the effect, or a sample sound file of the actual effect.

There's not of actual noise there, so it could be almost anything. How about "Dirty Noise" (attached). Does that work?

It sounds like quantization noise ...
Dubya, before-after , EQ then Steve's Quantization distortion @85.wav
the setting of 85 on quantization distortion maybe a bit too much.

Steve made a distortion plugin for Audacity which includes a "quantization" option,
that plugin can be downloaded from here ... http://forum.audacityteam.org/viewtopic ... 96#p237796

Using a noise-gate with a 100-200ms decay will emulate the squelching effect of an actual radio transmission : where the hiss persists for a fraction of a second after the person stops speaking, then there is true silence until they speak again.
