Each Vocaloid is sold as "a singer in a box" designed to act as a replacement for an actual singer. Kagamine Len is a Vocaloid developed by Crypton Future Media as part of the Character Vocal series, like fellow Vocaloids Hatsune Miku and Megurine Luka. The software can change the stress of the pronunciations, add effects such as vibrato, or change the dynamics and tone of the voice. Since buying is the same process with some additional navigation, well only be showing you where to find the voicebanks. A piano roll type interface is used to input the melody and the lyrics can be entered on each note. Weve previously covered Sonicwire, but have yet to cover the Japanese side. To create a song, the user must input the melody and lyrics. It uses synthesizing technology with specially recorded vocals of voice actors or singers. The software enables users to synthesize singing by typing in lyrics and melody.
Backed by the Yamaha Corporation, it developed the software into the commercial product "Vocaloid".
Its signal processing part was developed through a joint research project led by Kenmochi Hideki at the Pompeu Fabra University in Barcelona, Catalonia, Spain, in 2000 (the same team that later founded Voctro Labs) and originally was not intended to be a full commercial project. Vocaloid (ボーカロイド Bōkaroido?) is a singing voice synthesizer.
