Human Coded Orchestraはコンピューターに演奏された人間の合唱です。集団の人々が即興でハーモニーを奏で歌えるようにする指向性スピーカーを利用した装置を使用し、人間の合唱の制御を可能にしています。複数の指向性スピーカーをそれぞれ違う方向に向け別の高さの音を発し，コンピューターで音階の空間分布を制御する．それぞれのスピーカーの前に立つ人々には，聞こえる音を真似してもらうだけで複雑なハーモニーを実現できます．利用者の側での準備がほとんどいらず，即興の集団パフォーマンスを実現する点において革新的です．

コンピューターに演奏された人間の合唱は，人間とコンピューターの関係において，音楽パフォマンス分野の新しい領域を開拓し，これからの時代において社会に革新的な変化をもたらすでしょう．

This is our installation, Human Coded Orchestra, a new approach to enable a group of individuals to sing in harmony by using computed directional speakers. The possibilities of musical performance by an untrained group have been explored in both scientific studies and artworks. However, previous work in this area has rarely gone beyond simple rhythm-based music and failed to achieve musical complexity. Human Coded Orchestra employs a number of directional speakers, each set at a different pitch, so that they will deliver different pitches to each participant to sing to, according to their positions.

The present system does not require any preparation on the part of singers, which opens up the possibility of practical application in the interactive performance area.

I am in charge of program (max / msp, Processing), song editing (GarageBand), paper writing, circuit design, circuit production, cabinet design (Adobe Illustrator), casing production (Laser Cut)
