Is there a simple way to do a velocity envelope type thing for audio? I know there must be. Then again I know I should have gotten more sleep last night too.
That is so bizzare! I would have thought it was a fairly common effect, for example to mimic a record being slowed down, or one of those scenes where image and sound slow down (like when the hero's friend gets killed and time seems to slow down).
Of course, you can slow down audio in Vegas, but only at constant rates instead of a smooth variation. I suppose you could split the audio into lots of little bits and stretch each successive bit just a little more than the one before it.. The transitions between the bits would probably be rather noticeable though.
Option 1: dump it to tape and slow the tape down (analog).
Optoin 2: open the audio into SoundForge and apply not a pitch shift, but a PITCH BEND, linear curve, lasting the same amount of time that the video is slowed down.
Save it, go back to Vegas, and there you go.
(Actually, i'd "OPEN A COPY IN SOUND FORGE", thereby keeping the orignal audio clip untouched just incase you want to go back and undo it)
