"Dub" refers to a genre of music that originated in Jamaica in the late 1960s. It is characterized by the remixing of existing recordings, often emphasizing bass lines and drum patterns while adding effects like reverb and echo. Dub music is closely associated with reggae and has influenced various other genres, including electronic and hip-hop. In addition to music, "dub" can also refer to the practice of replacing the original dialogue in a film or television show with a new language. This process, known as dubbing, allows audiences to enjoy content in their native language while maintaining the original visuals.
