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.

That's it. There is a natural granularity (1 frame) to CD tracks, and if
files don't fade to zero at each end, the odds of clicks are pretty good
when you try to butt them together.

OK this sounds like what my problem is.

Fractional frames are padded out with zeroes, and if the adjoining data is
non-zero you get clicks.

does anyone know how to split on block boundaries in sound forge?

There should be an option for setting the time base to be in frames, which I
believe forces all files to begin and end on frame boundaries.
