Title: splicing tracs
Post by: admkrk on June 05, 2005, 01:04:10 PM
i have one that is missing about the first min. or so and want to splice the missing part w/ a different source. i figured the waveforms would be similar and it wouldn't be too hard to match them up, boy was i wrong!  using sf7, is there a way to get the two synced up so i can hook them together, or would i just be better off tossing my song and just puting the other in it's place?  i'd still need to smoth out the transition, but between tracs is simple. i'd like to work on this when i get back home tonight, so any advice would be grately 'priciated.

  thanks,        kirk

I don't know of a way to do it in SF. I've always used a montage in wavelab for this task.

experiment with the crossfade between the 2 sources - make sure they both have the same curve {actually straight would be best} - if they are really different sounding there isn't much you can do but by doing a longer crossfade it might smooth the transition so while still noticable it isn't as harsh and is more listenable

Line up the two WAV files in a multitrack/montage editor, so they overlap like so:
                                     [----------track 1, primary source, missing first min-----]
[-----track 2 w/ first min intact----------]
Make sure the two tracks are time-aligned for the part that overlaps by picking an easily identifiable section of each waveform to line up.  Then, apply to the parts that overlap:  crossfade-in track 1, crossfade-out track 2.

can't find anything like that in sound forge? here's a shot of the two lined up as best as i could.nothing i try works though.

Okay, so they seem reasonably well lined up (tough to tell for sure without a closer zoom).  Not sure how SF lists crossfade - have you tried the Help file?  All the online references I see to Soundforge include the keyword "crossfade", so I suspect it's in there.

yeah, went through it a couple of times. i might just be doing it wrong, but i can't get it to start at the begining. it always starts out were my tape cuts in, then starts playing both at the same time  ???.  maybe i'll just go w/ replacing the whole song, rather not though.

If you can "aquire" a copy of Wavelab or Vegas (I prefer Wavelab), you're task will be many times easier.

PM me if you have any more questions!
