IA (Japanese:イア) is a humanoidpersona voiced by a singingsynthesizer application developed by 1st Place Co., Ltd., headquartered inMeguro,Tokyo, Japan. She usesYamaha Corporation'sVocaloid 3 singing synthesizer technology. Her voice is created using samples ofLia. She has performed at live concerts onstage as either an animated projection or aPepper's ghost. Arhythm game featuring her calledIA/VT Colorful was made. Many songs have been made with her.
IA's name was taken from her voice provider's name, "Lia". She was illustrated byAka Akasaka, the author ofKaguya-sama: Love Is War andOshi no Ko.
AfterLia got married and became pregnant in 2009, she was forced to put her career on hold. Because of this, production began on IA as a way to "stand in" as a substitute during the singer's absence.[1]
IA was developed by 1st Place Co., Ltd. using Yamaha's Vocaloid 3. Her voice was created by taking voice samples fromJapanese singer Lia at a controlled pitch and tone. She was the first release for the "Aria on the Planetes" project, of which theCeVIO Creative Studio vocal, also made by 1st Place, named "One", is also a part of.[2]
The design philosophy 1st Place worked toward was to make the voice simple but easy to adjust and customize, letting creators create their own version of IA.[1]
In October 2013, IA's software was announced to have an update for the Mac during the promotional period for the IA × Super GTCircuit Beats album.[3]
In 2014, a prototype vocal called "IA -Aria On the Planetes- α Type C" was released as a free trial version via a one-month-long feedback campaign.
On June 27, 2014, a new add-on for IA, called IA Rocks, was released.[4] Once imported into theVocaloid 4, it was possible to cross-synthesis the two vocals.
In January 2016, it was announced she would be released forCeVIO Creative Studio, receiving a talking vocal; this was released in 2018.[5]
Information on IA was released much more slowly than the average Vocaloid. Her promotions have taken the approach to make her seem otherworldly and mysterious.
The licensing for IA is slightly different than past Vocaloids. Unlike some past Vocaloids, users can use her image on CDs, flyers and posters without requesting permission, although some consent from the company is needed for greater use of her image. This is a departure from past Vocaloids such as Crypton Future Media, which requires permission for use of their Vocaloids' images on things such as CDs, flyers and posters.
