ioa747,
You noted, "Now the script is ok? "...Yes it it! Thanks so much!
The .edl file I employ are derived from an application entitled, "Software Audio WorkShop"...or "SAW" for short.
From the SAWStudio User Manual, SAWStudio Fundamentals, SAWStudio Terminology:
"EDL: Edit Decision List.
An EDL stores all session related information including automation, mixer configuration, region data and soundfile link information. An EDL does not store the actual soundfile data."
Hope this helps?
