newbie- using sf to fill gaps in audio -Sound Forge - PC

Subject:newbie- using sf to fill gaps in audio Posted by: Tempest Date:5/4/1999 7:43:02 AM I've recorded some streamed audio into wav files off the internet. I'm trying to use sf to clean them up in order to burn to cd. The problem I have is that there are drop outs in the music lasting from a fraction of a second to 3-5 seconds. As it's "dance" music, I could probably "patch" the sounds, but I'm having trouble figuring out what the best way to start is. If I just want to eliminate a small gap, what's the best way to do this? Deleting takes forever (the file I'm working with is 2 hours). For the longer gaps, how to I overlay (and synch) another region? What I'm trying to explain is that the music has a certain beat pattern (wave pattern too, I guess) and that theoretically I could copy, say, 5 seconds and overlay it right over a gap, but the overlay is off by milliseconds resulting in garbage.

Try replacing a phrase containing the gap with a similar one, copied from somewhere else. If you take a bigger phrase it will be easier to line up beats. Then you have to zoom in and line up the wave form so that it doesn't pop. Using zero-crossings and smoothing helps with this. It takes a bit of trial and error to get things right. James

I've recorded some streamed audio into wav files off the internet. I'm
trying to use sf to clean them up in order to burn to cd. The problem I
have is that there are drop outs in the music lasting from a fraction of
a second to 3-5 seconds.

As it's "dance" music, I could probably "patch" the sounds, but I'm
having trouble figuring out what the best way to start is.

If I just want to eliminate a small gap, what's the best way to do this?
Deleting takes forever (the file I'm working with is 2 hours).

For the longer gaps, how to I overlay (and synch) another region? What
I'm trying to explain is that the music has a certain beat pattern (wave
pattern too, I guess) and that theoretically I could copy, say, 5 seconds
and overlay it right over a gap, but the overlay is off by milliseconds
resulting in garbage.

If there are any good resources, web sites and the like, please point me
to them.

Thanks,

Try separating the file into smaller chunks first, do your deletions, then
paste the chunks back together again.

Try replacing a phrase containing the gap with a similar one, copied from
somewhere else. If you take a bigger phrase it will be easier to line up
beats. Then you have to zoom in and line up the wave form so that it doesn't
