hello pro audio people
i use sound forge all the time for splitting up tracks. for example
when i record a concert on tape then prepare it for cd. my problem is
when i split a track during crowd noise before a song starts, after i
burn it to cd, maybe
50% of the time, i hear a click when the tracks move from one to
another when i listen to the cd. if i copy the files back to my
computer and rejoin them, there is no click. i have analyzed store
bought cds that have songs which segue and it seems there is no
particular spot that they split them, yet there is never a problem
with a click when you listen. is my burner adding the click?
is there a special point in the wave file where you should split the
tracks?

Others have suggested to make sure you make the splits at
zero-crossing points, and that will certainly help, but it is merely
reducing the effect rather than addressing the cause.

A CD is organised in blocks, each block being 1/75th second long (588
samples). If you present a file to be burned as a track that is not an
exact multiple of 588 samples, then the CD writing software will pad
the last block out (usually with silence). This is almost certainly
the source of the clicks you hear. You have to make sure that you
split the large file up on CD block boundaries (and then burn the CD
in Disc At Once mode to ensure there can be no pause between tracks).
I'm not that familiar with Sound Forge, but would have expected there
might be some way to tell it to place split points at CD block
boundaries. If not, there are very cheap programs out there that will
do the job. CD Wave (www.cdwave.com) is the best known one. My own
program Wave Repair (www.waverepair.com) will also do the job, but if
all you want is track splitting, CD Wave is easier to use.

this was the info that helped me...thanks
i split the tracks up and made sure that the total sample
length was divisible by 588 and I got perfectly clickless
segues. and the splits don't have to be a zero crossings.
