This article is about the VOCALOID3 software known as a voicebank. If you are looking for the VOCALOID character then click here.


When Lia got married and became pregnant in 2009, she was forced to put her career on hiatus. Because of this, production began on IA as a way to "stand in" as a substitute during the singer's absence.[1] Lia had heard of Hatsune Miku, but was unfamiliar with the VOCALOID software.[2]

1st Place entered production when VOCALOID3 was in place. The company did not want to make IA fit into the existing VOCALOID market, and decided to aim for a separate market instead.

In November 2011, a cover of the song "Tori no Uta", one of Lia's most acclaimed original songs, was released. The cover featured the beta voicebank. On December 14, 2011, two more demos were released, an on January 13, 2012, the full version of the intial beta demo was released via YouTube Broadcast and SoundCloud.

Mac version[]

In October 2013, IA's software was announced to have an update for VOCALOID NEO during the promotional period for the IA x SUPER GT CIRCUT BEATS album.[3] The free downloadable version for Windows users wishing to obtain the Mac version was then made available via the IA PROJECT main site on December 7, 2013.[4][5] Users who previously purchased the Windows version of the voice bank must provide their serial code included with the voice bank in order to download this version, as well as ensure that the Windows version is deactivated before installation onto the Mac operating system.

Package details as noted:

She is voiced by a professional singer with her vocals being similar to that of her voice providers' "Crystal-like" voice, making her a more realistic VOCALOID. Lia herself commented in an interview that although IA was based upon her vocal, she can sound so different to her at times.[2]

The licensing for IA is slightly different than past VOCALOIDs, and it is worth taking the time to read this page for more details. 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, who require you to ask permission for use of their VOCALOIDs' images on things such as CDs, flyers and posters.

Vocal traits as noted:
  • She has a light-toned voice that is soft and clear.
  • Some producers also consider her to be one of the most realistic sounding of the Japanese VOCALOID3 vocals released, if not the most realistic sounding Japanese vocal.
  • She is especially capable of producing long, drawn out notes and has an almost opera-esque result to her vocals when used correctly.
  • Some users report that her mid-range is relatively flat in comparison to her high notes.
  • She lacks power in her vocal and her voice will collapse quite easily.
  • Other users report that her high notes sound slightly muffled and unclear, resulting in a lack of clarity. Adjustments to EQ are a must in such cases.
  • As highlighted by VOCALOID NET's article, IA's vocal has a variety of roles she can fulfill such as pop, rock, ballad and dance and recommended she be used for these genres. She was recommended for newbies because her voice was easy to tame owed to its transitions between words.[6]
  • One of the highlights of IA is the large tempo range allowing the vocal to cover a large umber of musical genres.
    • At 228BPM, IA and IA ROCKS have the fastest tempo range of VOCALOID3.
    • At a total coverage of 165 BPM range, IA and IA ROCKS also have the largest tempo coverage of any VOCALOID3 vocal.

Voicebank sample


Cross-Synthesis as noted:

If both IA and IA ROCKS are imported into VOCALOID4 then the option to cross-synthesis (XSY) the two vocals is possible.

  • In total the package offers the equivalent of 2 additional voicebanks achievable via XSY. The total tone variation offered by the package comes to a theoretical 4 voicebanks in total.
  • Note that these vocals were not designed to be used for XSY originally as it was not part of the VOCALOID3 engine functions. Results may be rougher than VOCALOID4 XSY vocals for that reason.
