LC Concept was a 35 mm film projection sound format, developed in France and released in 1991. It used 5.25" 300 megabyte capacity re-writable magneto-optical disks to hold 4 or 5.1 channels of MUSICAM compressed audio. Two disks were used to hold approximately three hours of sound. The system was not widely adopted and the company failed in 1994 due to a lack of funding.

The system was developed by Elisabeth Lochen and Pascal Chedeville. A standard SMPTE timecode printed next to analogue soundtrack on the film print was read by a reader connected to the playback unit kept the playback in sync. The system was tested with a re-release of the Cyrano de Bergerac, and the first commericial release was "Bis ans Ende der Welt".
