Hey There,

I'm using Pandora's Toolbox file "44 Area 53." It is a long
non-looped file. I'm trying to extend it. I would like to paint
it onto the track a second time, then erase the first few bars of the
second instance (because there isn't much
activity there) and append it to the first track. I've erased a bit
of the end of the first instance as it is silent. The
problem is that I get an audible click/pause at the meeting point. Is
this caused by the memory having to skip to a
different part of the file? I'm using a P233 with 32MB of RAM.

I tried duplicating the track and doing cross over volume fades. This
was effective in mixing the file, but ACID
couldn't save the project as there seemed to be a naming convention
issue. I tried it again after saving "44 Area 53"
as "44 Area 53b" from Sound Forge, and using that as the second track,
but I got the same error message
referring to a lack of disk space or not having write permission in
the file or folder. The error stopped appearing
when I deleted the duplicate track.

Any ideas?

Thanks,

Wolf

The best way to accomplish this is to edit the loop in an
audio editing program like Sound Forge or Cool Edit. The
loop ends need to either be cross faded or meet at zero
points. Let me know if you need any advice on how to
accomplish this.

This problem occures when the end of a loop contains samples which
are in a positive range and the begining of the next samples are in
the negative range, basically acid (and most sound programs) are
reading where the two loops meet as a major spike, which sounds like
a pop. To solve this you can apply a volume envelope to your loop
and lower the volume at just the very begining, so that the volume is
not even noticeable.

I run into this problem a lot when I am creating melodies in cool
edit. Because the melody is often sustained even beyond the loop
(i.e. the loop cuts off and starts over before the melody is actually
completed) there is often a pop where the loop begins and ends. I
apply a fade out to the end of the melody, but only for just about 20
samples or so (not a lot!) and that kills the problem.
