Steve, the link above was no good for me, so I'm gonna try and just wing it.
A "whoosh" effect can take place in a lot of ways, and in combinations of those ways.
The first I'll suggest will be the well known Doppler effect, which combines probably all of the ways I'll suggest:
1) amplitude, in which the sound gets louder as it comes into a certain range of hearing. This can be done easily in a variety of ways, but the fact remains in a stereo field, you will pick a certain spot where the audiences hearing is considered to be, and make it louder there, and more quiet in other spots. You'll do that over
time, and using
pan. That is, play a certain sound- let's say a sustained trumpet note that lasts for 15 seconds- and make it be louder in the center rather than on the left or right side at a certain point, and the listener will imagine themselves at the center of it, and picture movement occurring from left to right- or however you set it up.
2) tonality, again using the Doppler effect, things far off don't reveal themselves in their full audio range further away as they do close up. That is, they sound more fully in the sound spectrum when it's closer to you than they do far away. That's only natural- think of an echo's "HELLO- Hello- hello" and you can duplicate that by removing some amplitude, which I brought up above, and also by removing some of the original sound spectrum (removing bass and treble), which will make it seem as if it was moving away, which is what things in real life do, as illustrated above with the echo.
And the way to do this in a DAW is by using
automation, which will allow you to adjust the tonality (by automating EQ) and the volume (by automating amplitude) over time, and by using the pan controls (which can also be automated). I hope any of this helps, if you want, I can maybe send a file in which I've done this to your email, which may clear it up. Good luck, L
