The best way to achieve this would be to use the FM tone generator in Sound Forge. Lacking that and assuming you already have the 1KHz tone do this.

Add the Elastique FX to the track header. R Click the track header and select insert automation envelope. Select the Elastique FX and tick the pitch ratio box. Add nodes and adjust envelope as needed to get the effect reuqired. You are limited to +/- 2 octaves though. Give that it's a sine wave you could render out and repeat I suspect without anything falling apart too badly if you needed a larger pitch shift.

Sounds good but you lost me. How do I add Elastique FX? Can't find it in Vegas 9e.

The vibrato fx will do what you want.

Just played a little more with the vibrato. You can make all sorts of sirens, alerts, etc. Set the modulation frequency between 0.5Hz. and 2 or 3Hz and have fun.

Just checked in V9.0e and it is there as elastique Timestretch.

You did click the track FX icon in the track header?
Then select add and look under Sony and you should find it.

"What I want is a "pitch envelope" on a 1k tone on an audio track."

If you change the pitch, it's no longer a 1kHz tone.....

Try this:

Thanks Bob.

LarryP's Vibrato idea actually provides exactly what I was looking for.

The Vibrato plug-in works with FX Automation (not all plug-ins can be controlled with FX Automation) to provide a keyframe envelope for each of the selected Vibrato control perameters. Amazing!

Working with a simple 1k tone, Vibrato can modulate it eight ways from Sunday. Sounds like a Theremin from a1950's scifi flick.

Adding vibrato to other sounds creates really weird stuff. The preset pulldowns include "weird" as a setting. How cool is that? I used a slowed down section of a song and it's weirder than ever.

Add the Distortion plug-in and select its "wet slew" preset and the possibilities are endless.

I'm actually trying to create a sound that represents a jamming signal in space. This Vibrato will do great. Fun, too.

Thanks again.

That's the advantage of the elastique plug, best in the industry when it comes to artifacts.

I did send you an email so I could send you a project file using that FX, maybe your contact details are out of date. You can ping me if you still want it.

However on further thought maybe you don't have that plug.
I know V9 and V10 use the elastique technology for time remapping what I'm not certain of is if the actual plugin is also included. I also have SF10 and I may have 'acquired' that plugin in Vegas from SF10, don't know for sure.

If you'd like to be technically accurate, the normal IR tracking tone of the AIM-9M Sidewinder is a steady 1500 Hz, not a warbling 1000. In the newer version (AIM-9M-9) there are several different tones to indicate the Sidewinder is seeing (or thinks it is seeing) flares from the target aircraft and whether it thinks it can "hack" the IR countermeasures (flares). I forget the specifics on the different tones, but I'd suspect you're just looking for the normal lock-on tone anyway.
