Is there a way to keyframe the volume of a sound track attached to a prop?

I have a scene with a character sitting at a table in a room. I have an MP3 file attached to the room as a sound track. I want the sound track volume to start at one level, but when my character starts to speak I want to lower the volume of the sound track without turning it off. I haven't been able to figure out how to do this. Can the volume of a sound track be keyframed?

TIA

Anyway, I took a quick look in iClone. It doesn't seem like there is a way to set key frames to control sound volume. However, there is something that may achieve the effect that you want.

After importing the sound,  click at the sound file on the timeline. Place the cursor at the frame that you want the music to begin quite down, click the right mouse button and choose 'Break', move the cursor to the frame that you want the music to resume normal volume, click the right mouse button and choose 'Break'. You now have the sound file broken into three sections. The 2nd section is where you want to music at a lower volume.

If there is another place where you want the music to quiet down, then repeat the above until you have each of the quiet moments has its own section.

[Important: Proceed to adjust the volume ONLY AFTER the above have completed. Why? Just trust me on this for now -It is kind of late so I need to make this short]

Highlight a section where you want the music at a lower volume and move the volume slider to the left to reduce the volume. Do this for each of the sections where you want to music to quiet down.

I use Pinnacle Studio for video editing and simple compositing. I also use Sony Acid Music to create sound tracks for videos. Acid allows me to open a video player right inside the app, so that I can sync to the sound visually. Nice feature.

But, since IClone lets one add a sound to an object, I was wondering about volume control, etc.. I haven't tried it yet, but the method you describe makes sense according to what I have already learned in IClone. I'll get around to testing it this afternoon.

The other thing I've wondered about, regarding sound in IClone, is what happens when sound is attached to a moving object. I.E., if one attaches a sound to a car, and the car starts out close to the camera, will the sound fade as the car moves away? Cinema4D can do that.

In C4D you can place microphones and speakers. Speakers can have sounds attached, and if the speaker is animated in the scene, then, when rendered, the rendered sound will react according to how close or how far the speaker is from the microphone. It would be cool if IClone could do that. Maybe in a future version.

Thanks for the reply.
