Audio fade

Can anyone point me to some good examples, or explanations, of fading audio? For my Screenblast "teeth-cutting" project, I am assembling a video which will contain a mixture of stills and video, with a soundtrack running all the time. For the portions of live video, I want to fade the soundtrack down, fade in the video "voice" track (I guess) and reverse that process near the end of the video track. I was playing with audio envelopes, setting points and such, but it seems like there has to be a much easier way - either that, or its the right feature(s), and I am not using them correctly.

Try this: Turn on the audio envelope on the audio track you're working with. Find the point you want the volume to start increasing (or decreasing) and mart 2 points fairly close together there. Don't actually move the line now, just mark the points. Now find the point you want the volume to go back down. mark 2 points there. Now you should have a straight horizontal blue line with 2 points at the beginning of the fade and 2 points at the end. Now just grab the line in the middle, between the 2 sets of points and drag it to where you want it. Play with the beginning and end as necessary. Hope this helps!

Thanks Brian - that is what I have been doing - it just seemed to me there must be something a bit easier - like the equivalent of a transition, but for audio... perhaps where you have the ability to mark the 2 audio tracks then have an option to adjust the audio output between 2 sources, rather than having to mark and adjust each individually.... no?

If you overlap the audio clips you will get a cross-fade. If you right click on the overlap you'll get options for how the volumes should fade / swell.

IanG - What is the option named if I right-click on the overlap as you suggested? I do not see anything.

What I have is a sound track on the music track, and audio on the voice track. I've accomplished what I wanted with by adding points on the audio envelope, but it just seemed overly manual, and I had to add separate points to each of the two audio tracks. I thought for sure there would be some way to apply a single "effect"...

I FOUND IT! Turns out that I can drag the voice track from the video down to the music track - THEN I see the audio fade options IanG was mentioning. Not sure if there is a down side to doing it this way, but it does seem to accomplish the intended purpose.

Let's back up a moment. How do you add markers to just the audio track? I can only add makers at the top to all the tracks, and these don't allow me to adjust the audio volume only between the markers. I'm on Screenblast MovieStudio 3.

I'm doing this from memory, so please forgive me if it's wrong! Select the audio clip (this is where I'm not sure - it might be the track) you want and then type V to add a volume envelope. You can click on the blue line to add marker points and then adjust the volume between the points.
