Help with Audio Level

Hi all,

Will someone please tell me as how I can Bring down the audio level in the middle of a scene and then raise the audio level up later? Is there a velocity envelope for audio as well?

Yes. On the menu, click insert, audio envelope, volume. A blue line appears on the track. At the start of where you want to reduce the volume, add a little marker box on the blue line by double clicking it. Then add another one just to the right of it. Go to where you want the sound to come back up on the track. Do the same (add two marker boxes by double clicking on the blue line). Now, inbetween the two inner boxes, click the blue line and drag it down to the bottom of the track. Notice that where the outside marker boxes are, the line stays at the same level. Play back your audio and listen to it "duck" to a lower volume, then return to normal. That's called ducking audio and is commonly used when there is voice over in your video that you want to hear. You can also raise the audio level the same way, just drag the line up. You can slide the marker boxes along the line to raise and lower the volume gradually. Add as many boxes as you want also. Hope this helps.

Another method would be to read/write automation data in the audio mixer. This way you could listen to the audio while riding the fader and be recording these volume changes. Reading back the automation will play back these moves while the project plays.

This is a slightly more audio engineer approach and works especially well if you have a controller like a Peavy PC1600 or whatever.
