The Creative Voice (VOC) format is a proprietary audio container developed by Creative Labs for its line of Sound Blaster sound cards. This file type was extensively utilized to store digital sound samples and recorded speech in early DOS-based video games and multimedia applications. Although now considered a legacy format, it is generally safe for modern use and remains recognized by specialized media players for historical preservation and data recovery purposes.
