Effects

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.

How do we model circuits?

Why a circuit rather than a curve

Because the parts have state, and a curve does not. A transformer core integrates voltage over time, so it saturates differently on a low note than a high one - the frequency is in the answer because the time is in the equation. A photocell has a chemistry that takes a tenth of a second to relax, so the sweep it drives is lopsided whatever shape you feed it. A shared supply droops under load, so the sound changes while you hold it and the other channel hears about it.

None of those can be drawn as a curve and then looked up, which is the whole reason to solve the circuit instead. It costs more to run and it is the only way to get behaviour that depends on what you just did.

The same library builds the synths and the drum machines.
