Subject:Crossfade question Posted by: pbeshuk Date:5/16/2002 9:17:23 PM I'd appreciate any help with this: I have some live 2-track recordings with a lot of crowd noise between the songs. I'd like to delete portions of these crowd noise sections and not have any hearable break points. I've tried Crossfade, but it seems that unless the source and destination lengths are exactly the same (is that possible?), I introduce a discontinuity. THe levels are very low at these points, but it is an audible "seam". I suppose I could just delete the section I wanted to remove and try to repair (eg pencil tool repairing) the discontinuity at the seam, but sometimes the level is so low at these points it's like there is no waveform to work with. Just fading down to complete silence over these seams is probably not a solution as that might be also be an audible discontinuity. Also, the other repair tools are hard to use since there is not noticable "glitch" in the waveform (although I haven't tried all of them yet). Thanks.

Subject:RE: Crossfade question Reply by: doctorfish Date:5/17/2002 6:15:52 PM I agree. Use Vegas for crossfading different tracks. I always do and it's so easy. In my response to SF regarding the Forge 6 Beta, I asked for the ability to make crossfades easier by allowing for some dragging and adjusting after you mix from the clipboard, maybe by having some kind of "settle" button that would lock the mix in place once you've got it right. (That reminds me. I'll go back to the product suggestion page and ask again.) Or they could give Sound Forge some mutli-track capability, say two stereo tracks or 4 mono at once. Until then though, I'll use Vegas for crossfading. Dave
