Pawel already answered to Christian's question. More: Christian, you don't mention, how old the movie examples are. The majority of movie sound has been using Dolby Surround from the beginning of the 80's. With Dolby Surround sound, you can try to decode the soundtrack with a Pro Logic decoder and simply leave the center channel out. Practically all dialogue is placed center front at the mix. With Dolby Digital or DTS movies, decode the sound and leave center out. The music and the sound effects are usually stereo between L and R channels. The rear channels contain mostly ambience and occasional sound effects. If the soundtrack is plain two channel stereo, Pawel already made good points on it. It may be difficult to "separate" the dialogue from it. In addition to the Adobe Audition feature, google for "vocal removers". Some of them just cancel out all such information that is in-phase and equal level between the channels, some use a bit more clever strategy. hope this helps Eero Aro
