02 / How it works

Three-act loop

Act 01
Process the signal

Build your own digital signal processing tools on a visual flowchart interface. No prior knowledge required. Connect blocks, filter out noise, and lock onto the carrier wave.

Act 02
Translate the language

The extracted symbols mean nothing yet. Analyze their frequency and distribution to find word boundaries, identify phonemes, map out grammar. You are not translating from a known language.

Act 03
Interpret the meaning

The message was designed to be understood. Mathematics first, then physics: building a shared vocabulary from first principles. Each decoded layer unlocks the next.
