After using this great tut http://forum.doom9.org/showthread.php?s=&threadid=60137 , i understud alot of thigs . ok
I used Cool edit pro to conver an audio file 1.5 hour to 3 parts , each 30 mins and 48khz , than runned each throught Bidule . on every result runned it trhought besweet to get 6 mono channels . But now in the tut the next step says : Slip each channel together . example : 1 LFE + 2 LFE + 3 LFE = to get 1 LFE channel , what software can do that ?
