You do realize this is totally off-topic for this mailinglist?
But fine, I'll bite.
set JOB=c:\work\MISS PETTIGREW LIVES FOR A DAY [2007]
set DELAY2CH=%JOB%DELAY2CH.ac3
set DELAY6CH=%JOB%DELAY6CH.ac3
set SOURCEa0_=%_JOB%a0.ac3

ffmpeg -y -safe 0 -i "%JOB%CONCATa0.txt" "%_DELAYEDa0_%"
echo ffconcat version 1.0>"%JOB%CONCATa1.txt"
echo file '%DELAY6CH%'>>"%JOB%CONCATa1.txt"

%_JOB% doesn't exist.
%_DELAYEDa0_% doesn't exist.
%_DELAYEDa1_% doesn't exist.
I would recommend quoting your variables when spaces are involved.
The following works for me:
SET "JOB=D:\work\MISS PETTIGREW LIVES FOR A DAY [2007]"
SET "DELAY2CH=%JOB%DELAY2CH.ac3"
SET "DELAY6CH=%JOB%DELAY6CH.ac3"
SET "SOURCEa0=%JOB%a0.ac3"
SET "SOURCEa1=%JOB%a1.ac3"
SET "DELAYEDa0=%JOB%DELAYEDa0.ac3"
SET "DELAYEDa1=%JOB%DELAYEDa1.ac3"
echo ffconcat version 1.0>"%JOB%CONCATa0.txt"
echo file '%DELAY2CH%'>>"%JOB%CONCATa0.txt"
echo file '%SOURCEa0%'>>"%JOB%CONCATa0.txt"
ffmpeg -y -safe 0 -i "%JOB%CONCATa0.txt" "%DELAYEDa0%"
echo ffconcat version 1.0>"%JOB%CONCATa1.txt"
echo file '%DELAY6CH%'>>"%JOB%CONCATa1.txt"
echo file '%SOURCEa1%'>>"%JOB%CONCATa1.txt"
ffmpeg -y -safe 0 -i "%JOB%CONCATa1.txt" "%DELAYEDa1%"
But why so many unneccesary variables? Also the creation of the
ffconcat-file can be done more efficiently. How about:
SET "JOB=D:\work\MISS PETTIGREW LIVES FOR A DAY [2007]"
(FOR %%A IN ("%JOB%DELAY2CH.ac3" "%JOB%a0.ac3") DO @ECHO file '%%~A') >
"%JOB%CONCATa0.txt"
ffmpeg -y -safe 0 -f concat -i "%JOB%CONCATa0.txt" "%JOB%DELAYEDa0.ac3"
(FOR %%A IN ("%JOB%DELAY6CH.ac3","%JOB%a1.ac3") DO @ECHO file '%%~A') >
"%JOB%CONCATa1.txt"
ffmpeg -y -safe 0 -f concat -i "%JOB%CONCATa1.txt" "%JOB%DELAYEDa1.ac3"
