Pangenerator Creates Troop Of Robotic Backing Singers And Dancers

Speakers that form an “eight-channel robotic choir” bob up and down in response to a singer’s voice in a setup by Polish studio Pangenerator (+ movie).

Making use of Pangenerator’s Echoooooooo system, a performer’s voice is processed via eight channels and fed to eight speakers, every of which moves in response to the volume and tone of the generated sound.

Echoooooooo is produced from off-the-shelf speakers mounted onto a simple frame. The voice of the user is fed from a microphone into a “pure information patch” – pure data is a visual programming language created by Miller Puckette in the 1990s for producing interactive computer music and multimedia works.

It is then delayed, glitched or pitch-shifted into eight separate audio channels, every of which is connected to 1 of the speakers.

This outcomes in eight different interpretations of the sound the user is creating.

“Considering that we can sequentially delay the signal to the speakers, the echo-like effect could be achieved and therefore the name of the project – Echoooooooo – with eight ‘o’s for the eight speakers,” said the designers.

The up-down movement of the speaker is linked to volume of the sound – the louder the voice, the higher the speaker moves. The proper-to-left movement is linked to the tone.

“The custom-made building is as minimalistic and unobtrusive as attainable,” stated the designers. “It really is in line with the significantly less-is-more aesthetic that we tend to apply.”

The project came about as a result of Pangenerator member Krzysztof Cybulski’s investigations into digitally-controlled acoustic feedback – he mechanically controlled the position of a single speaker in relation to the microphone to create a distinct tone.

“The unintended side impact was the lifelike, quite adorable movement of the speaker making it perceivable as a living organism in that Pixar lamp sense,” mentioned the designers.

That drew the focus of Jakub Koźniewski, an additional panGenerator member, and he developed the concept further.

Koźniewski linked specific sounds with planned choreography of multiple speakers, mounting them on a custom-created construction and creating the device interactive. The rest of the group completed the project.

“1 of the factors that is clearly observed in this project is the phenomenon of serendipity – discovering new concepts not by focusing challenging to create some thing in a totally planned style, but rather experimenting freely and sparking unexpected new suggestions along the way,” said the designers.

The designers see applications both for a general audience in a karaoke setting, and for live concerts given by expert singers with the robotic choir as backing singers.

Pangenerator has previously created jewellery with projected light and an installation of pyramids that flashed in waves of illumination.
