Parts of the soundtrack have been recorded with the Warsaw Philharmonic Orchestra, orchestrated by Yoshihisa Hirano.

The soundtrack was composed in a period of about one year. Hamauzu's first compositions for Final Fantasy XIII were scores for the footage shown in events or game shows in 20 (notably " Blinded By Light"), and he didn't begin composing the full soundtrack until autumn 2008. The main tools used in producing the soundtrack were Digital Performer, orchestral samples by East West, and some standard software synth by Native Instruments, although a lot of live instruments were used, along with vocals in the many background themes of different locations. The game's director, Motomu Toriyama, requested an orchestral and futuristic hybrid sound, but gave Hamauzu freedom to exercise his own style. The proposition was a surprise to Hamauzu, who was nevertheless eager to accept. Yoshinori Kitase asked Masashi Hamauzu to compose the soundtrack.
