What's Inside
- Listening Lab — the same chord at A=432 and A=440 in random order. Pick which felt calmer and guess which was 432; the lab tracks your accuracy against 50% chance and your preference share.
- Binaural Generator — carrier frequency, Delta / Theta / Alpha / Beta presets or a custom beat, a timer and a safety-capped volume. Stopping logs the session automatically.
- Session Log — binaural, 432 music, 440 music or silence, with minutes, calm before and after, and focus after. Filter, sort and compare.
- Tuning Converter — every note from C3 to B5 at both references with play buttons, plus a converter for any frequency (432 ÷ 440 = −31.77 cents).
- Sound Journal — 24 reflection questions, mood score and streak.
- User Guide — the 1939 London conference and ISO 16:1975, Verdi's preference, what the 2019 pilot study did and did not show, and binaural basics with safety notes.

Questions
·
No. A small 2019 pilot study found slightly lower heart rates with 432 Hz music, which is interesting but not proof. This lab lets you test your own preference blind and track what helps you.
