Hey Product Hunt! 👋 I'm Christian, solo maker of PurePitch432. I got curious about the 432Hz vs 440Hz tuning debate a while back — a lot of people say 432Hz feels warmer and easier on the ears. The science is genuinely mixed, but the community asking for it is real. The problem: there was no easy way to actually listen to your everyday Spotify or Apple Music library in 432Hz — you'd need special software or convert tracks one by one. So I built a browser extension that retunes your music in real time, right inside Spotify (Chrome & Firefox) and Apple Music (Chrome only — Apple's DRM blocks it in Firefox). No downloads, no re-encoding — it pitch-shifts the audio stream as it plays. You can try it free (1 song/day, no signup needed for that). I'd love your feedback on: 1. Does the pitch shift sound clean to your ears, or do you notice artifacts? 2. Had you heard of 432Hz tuning before, or is this new to you? 3. What would make this a no-brainer purchase for you? I'll be here all day answering questions — thanks for checking it out!
