The Cotodama lyric speaker was produced to act as a canvas that would digitally display the lyrics to any song playing through its speakers. Although this doesn’t exactly fall under the classification of computationally generated music, I feel like this is a product that works under very similar mechanics.
I like the product itself due to its elegant look, though it looks as if it comes as two separate pieces, it is actually one solid unit designed to look like vinyl record jackets leaned up against the wall. I also think it’s a great example of sound data being used in coordination with databases to create visuals. When connected to an audio source, its display panel sources lyrics from databases
and displays the lyrics in sync with the song. It also is programmed to analyze a song’s mood to pick corresponding fonts and animations. In cases where no lyrics can be found for a song, the speaker will display AI-generated animations that move in sync with the music instead.
