Hi Steve,

This is easily done with Sound Forge 10 or 11 Pro by using the Event Tool. If you have two side consecutively in the same file, insert a short silence between them. Then, switch from the Edit Tool to the Event Tool. The areas either side of the silence are Events. Simply drag the one on the left over the one on the right and position it until you've got it in the right place. Alternately, if you pasted the file for one side into a new window, and then paste the second side at the end of that window, you've created two events. When you switch to the Event Tool, you can drag the second side over the first the same way.

If you right click where the curves intersect in the overlap area, you'll get a window that allows you to select the shape of the fade-out and fade-in in the overlap region. The default shape has a dot next to it - that's the one I use most of the time. 

There's an alternate way of doing this, which is useful if you don't want the same fade-out and fade-in shapes at the join. Use the Graphic Fade function (perhaps in conjunction with the other fade-in and fade-out choices) in Sound Forge to create the fades you want. Then, select the second side and CUT it. Then, use the Mix Paste function to set it into the end of the first side where you want it (Edit/Paste Special/Mix). I rarely get it right the first time this way. You'll have to try it a few times to get it right. If you've faded beforehand, this may be your best bet. But, if you faded only on the noise at the end of the side beforehand, the first method will probably work best. 

When I join 78 sides, I don't do any manual fading during the transfer. I do everything in my editor.

I had thought that you were using Sound Forge, but I could be mistaken. I hope this helps, and I hope I've understood your question correctly.

Subject: [ARSCLIST] 78 overlap program

I'm looking for software that will allow me to do the following: 


Work on a mono file of 78s sides of long works divided into 4 minute or so segments and, by dragging and dropping, make overlaps.  The 78 files will have been faded beforehand.  I want to be able to try, audition, and reposition each overlap until I'm satisfied.  


If this is not available in a program marketed for music, might it be included in one for verbal material?


I work in Windows wav files, 96/24.


It can just be a plug-in or separate for this purpose alone.


Anything out there?
