Kagamine

Kagamine is a Japanese vocal software developed by Crypton Future Media. It is part of their Vocaloid series, which allows users to synthesize singing voices. The Kagamine voicebanks are notable for featuring twin characters, Rin and Len Kagamine, who are often depicted as siblings or alternate gender versions of each other. Their design is based on a yellow and white color scheme, and their initial release in 2007 marked a significant point in the Vocaloid community, offering a more youthful and energetic sound compared to earlier releases.

Their voices are derived from voice actresses who provided sampled speech and singing phrases. Crypton Future Media has released multiple iterations of the Kagamine voicebanks, including updates that refine the vocal quality and expand the range of expression. The characters are frequently featured in concerts and media, solidifying their status as prominent figures in the virtual idol landscape. Their accessibility and versatile vocal qualities have made them a favorite among music producers and fans alike.
