What does a state change sound like and look like? A Japan-based artist who releases work under the name barbe_generative_diary explores these questions in a 2024 plotter drawing. Sound Visualization Plot | Dry Ice Using Various Types of Microphones is representative of the artist’s process, which begins with field recordings taken as a kind of media art diary. In this case, the recording is of the sound of dry ice turning instantly to gas upon contact with water, captured using four different types of microphones: stereo air microphones (basicUcho), a hydrophone (H2a), a contact microphone (C411 PP), and a geophone (Geofón).
For each drawing, the audio data is translated into a visual composition with the help of generative code, which is then executed by an Axidraw SE/A3 pen plotter. The monochromatic images of abstract forms are intended to both capture and evoke the sounds they were derived from: here, the alchemical process of a solid transforming into vapor.
