Soundscape Maa was released by the Istitute For Alien Research (ifarlabel) in a compilation entitled Concrète Poetry Four on Bandcamp.

The composition combines everyday sounds such as footsteps on different surfaces, the tearing of paper, lighting a match, playing tennis, clapping hands, horses clattering, machine noises and the like with voice samples from my archive, which the Dutch mezzo-soprano singer Jannie Pranger made available to me some time ago and of which a few have been electroni- cally manipulated. These two components are tightly interwoven and form an exciting, multi-layered and multi-faceted musique concrète.
The everyday sounds are treated in the same way as the vocal sounds; for example, in the way one deals with the sounds of percussion instruments, which are also largely noisy. A drum roll, a cymbal crash, a rattle ... or an electric saw, a creaking door, shattering glass, the impact of a golf ball, a swarm of bees, etc. The mezzo-soprano voice involved is extremely varied. Snapping or hissing sounds, whispering, speaking, singing, whistling, blowing and every conceivable sound that can be produced with the voice are included. Earth is the only planet known to date that sounds; where we are constantly surrounded by sounds and noises produced by humans and animals, wind, water, etc. I wanted to represent and celebrate a tiny section of this unique sonic diversity of planet Earth in my composition. The word “maa” in the title is the Finnish word for earth/land.

Soundscape Maa

In TrajSynth, created for 32-channel diffusion, I explore the use of artificial intelligence as a generative tool - not for producing entire sound materials directly, but for sonifying the dynamic numerical processes that AI methods inherently generate. These constantly evolving numbers, often ignored in mainstream AI-music platforms, carry a latent energy that I find highly effective for sound creation. Rather than relying on ready-made platforms, I focus on tapping into the internal workings of AI – extracting numerical data from within neural networks or training loops - and translating tha...

Special Thanks To Jean Voguet, for giving me the opportunity to work on CRANE lab's 32.2 volumiphonic device in 06/07/2025 and for inviting me to participate in his Curated By series on Sounding Future. And to Fränk Zimmer, for organizing the project and guiding us through the process, offering the opportunity to present our works on the Sounding Future platform for 3D Audio Space.
