N. I. Mueller (or NM for short) is a Black Forest-born maker and discoverer of sounds who works under a handful of project names such as Ypsmael, SmaelyP, AeLypsm, etc. Doubling as a producer at Soundindex, a compact studio in Meersburg, he spans composed, improvised and experimental musics as well as radio art. His work is noted for ranging between "opulent, raw, almost physical, a tour de force [...] sound composition that creates powerful images" (Award Jury, Hörspielwiese Köln, Germany); "delicate, highly atmospheric music" (Vital Weekly, Netherlands) and "exploring the grains and textures of his materials [...] to create a very distinctive language of his own" (The Sound Projector Music Magazine & Radio Show, UK). 

Since 2022, he works as an academic staff member in research and degree programme development for Trossingen University of Music's Master of Music - Composition, offering pathways in AI music design, electroacoustic composition and instrumental composition.
