Synths
The art and science of sound
Aphelion is a research-driven audio company exploring the outer reaches of what is practically possible in sound. We build instruments and effects by starting from first principles, whether that means modeling the physics of a room, the behavior of an analog circuit, or rethinking the assumptions behind synthesis, sequencing, and signal processing altogether. Our work sits somewhere between engineering, acoustics, music technology, and experimental design: rigorous enough to measure, strange enough to discover something new, and always built in service of music. We are less interested in reproducing the conventions of audio software than in finding out what becomes possible when those conventions are treated as questions instead of rules.
