Use foobar 0.9 beta (beta 6 onward I think), 0.8.3 with
my adapted Diskwriter component, or 0.8.3 to do the merge and then
foo_cuesheetcreator to create the cuesheet.
However, merging the files in foobar will mean re-encoding and therefore quality will be lost.
I can't think at the moment what tools there are to join MP3s without re-encoding. My brain is fried - there must be some...
It would be best to drag the files into a new playlist in foobar 0.8.3, use
foo_cuesheetcreator to create the cuesheet, and then join them without re-encoding using another tool.
I'm not overly sure why you'd bother joining them though...
Edit: searched and found these two (
one) (
two) threads. Neither seems overly convincing though.
Edit #2: Two more (
three) (
four)
