The piece of audio visualisation artwork traced and responded to a piece of disappearing music/song in Hong Kong recently. It was a month long exercise(14 June – 13 July 2023) to create simple visualisations of the music using the various operations in TouchDesigner, every day before the music disappears in the public domain.
Unlike musical notations, audio visualisation is an irreversible process. It is quite impossible to recover the original music/song given a few visualisations of the same piece. Nevertheless, the variation in loudness, pitch and perhaps timbre can be visible.
Here are the screenshots all the animations in a month.
