Learn frequency using the A8 second. The physical sound does not change; the time ruler used to count its cycles does.
This bench is disconnected by default. Playback is locked until you explicitly connect it to the recovered A8 Core. Browser / Web Audio timing is downstream DAC machinery only; it never supplies the A8 second, score position or run state.
Start low and use modest volume. Sine is recommended. High frequencies can be unpleasant or inaudible, and browser hardware cannot reproduce every theoretical A8 value.
Native A8 waveform generated directly from the selected A8 frequency × A8 time ruler. This visual does not depend on browser audio samples, the DAC or the speaker. Audible output remains a downstream browser / hardware demonstration and may exhibit transducer artifacts at higher frequencies.
This selector sets the horizontal ruler in native A8 time. Changing frequency does not change the selected time window; it changes how many cycles fit inside that window.
Every adjacent button is an exact ×2 or ÷2 in cycles per A8 second. The small Hz number is deliberately secondary and generally does not look clean.
Halving and doubling operate on the native A8 frequency value. The physical browser oscillator is translated afterward.
A8 frequency is counted in cycles per A8 SECOND. The A8 timebase is referenced to the Jovian 1:2:4 recovery architecture — Io ×4 · Europa ×2 · Ganymede ×1. The conventional value below exists only so the browser audio engine can render the selected native A8 frequency. It is an implementation reference, not the A8 frequency ruler.
Primary: frequency is displayed as cycles per A8 second. Conventional Hertz remains a secondary browser/reference translation because Web Audio still requires cycles per conventional second.
Browser / DAC implementation: the physical output target is measured only after explicit connection to live recovered DAY_PHASE17. No fixed conventional-second constant drives playback.
A musical octave is a physical 2:1 frequency ratio. A8 does not create that acoustic relationship; it represents it cleanly because binary doubling and halving are already native operations.
The 2:1 octave ratio is the physical/acoustic fact. The unusually clean sequence 256 → 512 → 1024 is the A8 representation of that fact. This is “octave-friendly by structure,” not a claim that Nature itself uses an engineered numeral system.
