Re: fast editor for huge wav files

I just did a test run.  If you do not have .pk files already setup
and are going to use Cooledit.  You can do a multiple open of many
files by just "shift down arrow" on the open screen.  Then let it run
all night opening multi-gigs of files and creating your .pk files in
the process. Then just close the entire Cooledit in the morning and
when you want to open a file it will be fast. Then you can edit fast
and save one file while working on a second window of Cool Edit for
another file.

I hope that I understood your problems correctly.
