- Worth noticing
- The page says audio stays in the browser; its 808 tuner benchmark covers 780 synthesized kicks.
Field notes
The tools cover both quick lookups and small production tasks: the tempo finder reports half- and double-time alongside delay times, while Hum to MIDI offers MIDI and WAV files in a zip. A separate 432 Hz converter is described as preserving the song's length while lowering it by 31.8 cents. The page names Daniel Breyer in Berlin as the maker and calls the work human-made, AI-assisted.
