A free browser-based instrument that measures sound in hertz through a microphone, with pitch, spectrum, waveform, peak, history, and audio-file analysis tools.

Why it surfaced

This is more than a single-number frequency meter: it offers FFT controls, fundamental-frequency detection, harmonic peaks, CSV and JSON export, and a clearly documented measurement method. Audio stays on the device and is never uploaded, making the unusually thorough tool easy to try without much trust required.

Monica’s Calendar of Flowers

August 17’s newborn domains include a calendar that spreads flowers for Monica across the months after JP’s death, 17 years of a master mariner’s logbooks, the seconds between a modem connection and the first web request, and an Indian bus cabin carrying 632 songs.

This is one of 1,000 discoveries in the 2026-08-17 Domain Arrivals issue.
