Galaxian swooping sound

Does anyone have a wav similar to that in the galaxian game when the aleins swoop down that I could use, cant seem to find a suitable sound.

Mank thanks

Send me a version of Galaxian and I'll sort it out ;)

To be perfectly honest I can't remember what the sound was, I remember it just being a high pitched beep when they were high on the screen getting lower as they got lower... if that's the case all you need is a sine wave and adjust the pitch based on their Y co-ord.

Hi, this is the only sound that could find that shows the idea, but the quality is no good really. This is however a sample from the actual game

I was going to say that I didn't think it was a smooth sine curve more choppy and that sample proves it.

Just made this...
