Eep. I certainly hope you do not consider me a charlatan. I work with biodata-sonification modules (also build & occasionally sell them). Still, I also do not claim its use as direct fungi or plant communication, more towards speculation/imagining other communication forms. The modules I work with are from open source code and schematics from one of the original engineers designing the MIDI Sprout (which eventually turned into the plant wave).
It works through detecting micro-fluctuations in conductivity (between 1,000-100,000 sec), with a 555 timer acting as a galvanizer, translating these signals in real-time (to MIDI &/or cv) through an ATMega with code allowing users to change scale, pitch, velocity, and more. That said imho if these tools offer humans a means of connecting on different levels with nonhumans by creating other forms of music/sounds. Or using the MIDI to disrupt visuals, control lighting (coming from a plant), and in return bring this into a public sphere of awareness - that is great and highly needed (positive human and nonhuman entanglements).
I have found my works that incorporate real-time, nonhuman bio-sonification illicit strong emotional, empathic responses towards nonhuman organisms.
I feel the most dangerous disease of humankind is the inability to imagine the world from another person’s, animal’s, and/or plant’s perspective. My work in nonhuman bio-sonification, fungi bio-materials, and immersive environments strive to overcome these biases.
